Restartowanie usług w dockerze
by rysiek 21 Aug '15

21 Aug '15

Elo, no więc mamy kilkadziesiąt różnych kontenerów z różnymi usługami, oddzielonymi i oddzielnie zarządzanymi -- a życie jest dobre. Na dole drzewka mieszkają sobie jakieś kontenery z mysql czy innym neo4j, nad nimi php-fpmy i django, wyżej jakiś nginx, a nad nginxem kontener co to musi mieć dostęp po www do jakiejś usługi na przykład. To wszystko rzecz jasna połączone, i zarządzane przez docker-compose. Zrestartowanie kontenera z mysql gdzieś na dole oznacza zerwanie linków i koniecznośc restartowania wszystkich kontenerów linkujących do niego, oraz linkujących do tychże kontnerów, i tak dalej -- czyli w najgorszym wypadku ~50 kontenerów na trzech poziomach: mysql -> php-fpm/django -> nginx -> nad nginxem To zajmuje czas i oznacza downtime, le fu-. Oczywiście mogę sobie ręcznie przepiąć iptablesy i inne /etc/hostsy, ale to też le fu-. Więc pytanie do wymiataczy dockerowych, których mam nadzieję mamy na tej liście: jak żyć, panie premierze? W sensie, what is the best practice jeśli idzie o restartowanie linked containers? Bo na pewno się jakoś da. Tylko jak? -- Pozdrawiam, Michał "rysiek" Woźniak Zmieniam klucz GPG :: http://rys.io/pl/147 GPG Key Transition :: http://rys.io/en/147

Elo, taka sytuacja. ---------- Treść przekazywanej wiadomości ---------- Temat: Death lists. Data: sobota, 8 sierpnia 2015, 19:25:26 Od: jim bell <jdb10987(a)yahoo.com> Do: Cpunks List <cypherpunks(a)cpunks.org> http://news.yahoo.com/rush-put-death-records-online-lets-anyone-killed-0744… Las Vegas (AFP) - Hackers at an infamous annual Def Con gathering in Las Vegas got schooled in how to be online killers.A rush to go digital with the process of registering deaths has made it simple for maliciously minded folks to have someone who is alive declared dead by the authorities. "This is a global problem," Australian computer security specialist Chris Rock said as he launched a presentation titled "I Will Kill You."The process of having someone officially stamped dead by getting a death certificate issued typically involves a doctor filling out one form and a funeral home filling out another, according to Rock's research.Once forms are submitted online, certificates declaring the listed person legally dead are generated. A fatal flaw in the system is that people can easily pose as real doctors and funeral directors, Rock demonstrated to a rapt audience. Doctors practising general medicine often don't bother setting up accounts at online portals for filling out information for death certificates.An aspiring online assassin can step into that void, and borrow the identity of a doctor. Setting up accounts requires a doctor's name, address, and medical license number. A basic Internet search will turn up that information, which is publicly available for the well-intended purpose of letting people check that physicians are legitimate before seeking care. Drop down boxes containing illness categories and online guides are available for filling in "doctor speak" on forms and avoiding medical causes or circumstances that might trigger needs for autopsies or investigations, Rock's demonstration showed. - No one off limits -Borrowing a funeral director's identity to establish an online account for death certificate purposes was shown to be simple as well. Required information about legitimate funeral directors is posted on the Internet, and one could even claim to work at a funeral home. In Rock's case, he made a website for a bogus funeral home and used that to back his application for an account as director. He got an automated call days later saying he was approved.With both online accounts in place, deaths can be registered in the real world. "You could kill anyone you want," Rock told AFP after the presentation. "No one is off limits."A humor-infused list of scenarios included killing oneself off to get life insurance cash or going after others for vengeance.Someone targeted might not even know they were declared dead until doing something official like trying to renew a passport or driving license. Rock began digging into the death industry a year ago after an Australian hospital accidentally declared 200 patients dead.- Virtual babies -Getting birth certificates for virtual babies was demonstrated to be even easier than killing off people in the digital world, because registering births online only involves doctors and parents. "Once you log on as a doctor, not only can you kill someone, you can actually birth someone," Rock said.Given the time it takes for even a make-believe baby to grow into adulthood, he saw that as more tempting to crime gangs who could invest in the future by creating legions of virtual people for shady doings involving loans, stock trading, imports or other activities. "You could even make fake identities for your children, so when they grow up they have burner identities," Rock said.He dove into virtual birth and death in his book titled "The Baby Harvest: How virtual babies become the future of terrorist financing and money laundering." ----------------------------------------- -- Pozdrawiam, Michał "rysiek" Woźniak Zmieniam klucz GPG :: http://rys.io/pl/147 GPG Key Transition :: http://rys.io/en/147

You must be able to remember three things to (re)generate your key pair; A user defined "username", which can be any string. A Teneo defined "profile" name. There's currently only one profile available: 2015v1, which uses scrypt() + salsa20/8 + sha256 as KDF.

TVN Turbo - program o kradzieżach.
by Wiktor Przybylski 29 Jul '15

29 Jul '15

Hej. TVN kręci siakiś program o kradzieżach w związku z czym dostalim takiego o maila (troche udziabałem z treści i personaliów, coby zapobiec ewentualnej tragedii): /"W serialu chcielibyśmy pokazać jakimi sposobami złodzieje okradają Polaków. Program ma być niejako poradnikiem dla widzów- jak ustrzec się przed kradzieżami- m.in. korzystając z materiałów, prezentowanych przez policję, z którą również współpracujemy. Tematyka będzie dość rozległa –począwszy od kradzieży samochodów, przez włamania i kradzieże kieszonkowe, na kradzieżach Internetowych kończąc. // / /W związku z odcinkiem o kradzieżach internetowych, //chciałabym móc skontaktować się z dziennikarzami i administratorami, którzy mogliby mi pomóc od strony merytorycznej//. Naszym wydawcom bardzo zależy również na utrzymaniu programu w bardzo realistycznej formie, stąd prośba o sugestię bądź kontakt z hakerem- który mógłby w programie opowiedzieć jakimi metodami się posługiwał- oraz jak każdy z nas może się przed nimi ustrzec. // / /Pragnę dodać , że współpracujemy z czołowymi, renomowanymi stacjami w Polsce - w tym z National Geographic, czy kanałami z grupy TVN. "/ I teraz tak, ja tu widzę kilka rzeczy: a) "chciałabym móc skontaktować się z dziennikarzami i administratorami, którzy mogliby mi pomóc od strony merytorycznej" - jeśli ktoś chce być mądrą gadającą buzią w telewizorni, która dodatkowo w swoje wypowiedzi powplata ponad dziewięć tysięcy memsów internetowych (bez tych o papieżu, zwyrodnialcy) - droga wolna. Jeśli bez memów, też droga wolna. b) "stąd prośba o sugestię bądź kontakt z hakerem- który mógłby w programie opowiedzieć jakimi metodami się posługiwał- oraz jak każdy z nas może się przed nimi ustrzec." - cheesy shit to unscrew - Ponad to czego potrzebują do tego serialu, to możnaby coś podziałać w sprawie ogólnopojętego ocieplania wizerunku hakera a także promocji naszych spejsów. Z tego co wiem o dziennikarzach, to lubio jak im sie gotowy temat podsuwa pod nos - polska scena hakerska i hakerspejsy w tefałenie? Wchodzę w to "jak nóż wjeżdża w masło" b) TVN często 'hakeruje' w tekstach - czy to nie dobry backdoor żeby to poodkręcać? Discuss.

Fwd: Announcement: Replicated Encrypted PasteBin

---------- Treść przekazywanej wiadomości ---------- Temat: Announcement: Replicated Encrypted PasteBin Data: sobota, 4 lipca 2015, 16:14:20 Do: cypherpunks(a)cpunks.org It's been a while since code was announced on cypherpunks... RepBin: https://github.com/repbin/repbin/tree/v0.0.1 Repbin is an encrypted pastebin for the command line that runs over Tor! Repbin servers form a distributed network where nodes sync posts with each other (like in Usenet or BBS/Fido systems). This makes Repbin resilient and scalable. Repbin focuses on privacy (encrypted messages) and anonymity (padding and repost chains). Features -------- - Forward secure encryption of posts using DHE-curve25519. Even a compromised long-term key does not allow to decrypt old posts. - Integrity protection of posts using HMAC-SHA256. You can be sure that posts have not been tampered with. - Confidentiality of posts using AES256-CTR. Without the recipient key, nobody can read the post. - All posts are padded to a common size. That means that posts are not distinguishable by their size when looking ``on the wire''. - Post are replicated between all servers in the Repbin network. - Optional constant receiver keys for post-box functionality. - Receiver key attributes for synchronization and post-box authentication. - Resource control via hashcash (sha256) and ed25519. - Some privacy protection by using Tor for all communication and ephemeral keys. - undocumented goodies. Post a file ----------- $ cat FILE | repclient As a response you will receive output like this: Pastebin Address: http://bvuk3xmvslx3idcj.onion/3x77hJtt42MkGbs18e1ZvBw9oAftAUrr9K9x4E8rQzed_… Simply give the Pastebin Address to whoever should gain access to the file. Fetch: $ repclient http://bvuk3xmvslx3idcj.onion/3x77hJtt42MkGbs18e1ZvBw9oAftAUrr9K9x4E8rQzed_… Installation ------------ Client software to send and receive file: $ go get -u github.com/repbin/repbin/cmd/repclient Peering ------- If you are an experienced UNIX sysadmin, please consider running your own Repbin server to help the Repbin network. While running a server requires hardly any interaction, setting up a server in the Repbin network requires at least one manual peering agreement with another server in the network. This is a time-tested architecture which is used successfully to run the Internet, the Usenet, and BBS networks like FidoNet. To set up a peering you have to exchange public peering keys with another server and configure your server accordingly. To get in touch with us for peering send a message to 7VW3oPLzQc7VS2anLyDtrdARDdSwa7QTF7h3N2t6J2VN_AjWZQfHoqK3yNqvXPkcswLNXSzFrCzJuRRKZKvY71UWT and don't forget to put your own key into the message. The server installation and the peering process is described in detail in the documentation. Here be dragons... ------------------ Dive deeper into the documentation and the code, if you want to figure out how to send repost messages (remailer style) and how to run your own reposter service!

Peer review
by Marek Marecki 19 Jul '15

19 Jul '15

Cześć! Pół roku temu (z małym hakiem) zacząłem pisać maszynę wirtualną. Nie potrafi jeszcze tyle co maszyna Javy czy interpreter Pythona, ale coś już można w niej napisać (jest gotowy wrapper na libnotify więc można np. wysłać sobie powiadomienie na pulpit, a na kod źródłowy składa się między innymi ponad 1500 linii kodu testów napisanych w języku assemblera maszyny). Z okazji wydania wersji 0.5.0 uznałem, że zapostuję na liście i poproszę brać hakerską o peer review. Thank you from the mountain za czas i każdy komentarz! Krótki przegląd podstawowej funkcjonalności: * programy są pisane w jeżyku assemblera maszyny i kompilowane do bytecodu przed wykonaniem, * instrukcje w maszynie operują na rejestrach (w przeciwieństwie do Javy czy Pythona, które operują stosem operandów), * maszyna obsługuje mechanizm throw/catch (można rzucać obiekty dowolnego typu, nie tylko wyjątki), * dostępne typy danych to int, boolean, float, string i vector, * dostępne są instrukcje warunkowe "jump" i "branch" oraz funkcje, Z bardziej zaawansowanych rzeczy, maszyna wspiera programowanie funkcyjne (w źródłach umieściłem moduł, który implementuje trzy główne funkcje: "map", "apply" i "filter", oraz również przydatną "invoke"). Da się też tworzyć funkcje zagnieżdżone. Jeśli ktoś lubi takie rzeczy to wie, że to fajna sprawa; a jak ktoś nie lubi to szkoda ;-) Przy błędach i niezłapanych wyjątkach CPU wyświetli ładny stack trace, z informacjami wystarczającymi do uruchomienia debuggera z breakpointem na odpowiedniej instrukcji. Zaimplementowałem wsparcie dla kompilacji rozłącznej, linkowania statycznego i dynamicznego, oraz linkowania modułów zewnętrzych napisanych w C++. Nie istnieje jeszcze możliwość tworzenia własnych typów danych, ale można symulować je za pomocą wektorów (z tego co wiem, w podobny sposób działa Lua). Nad utworzeniem systemu typów właśnie pracuję. Nie chcę pchać na listę zbyt dużego maila. Jeśli jednak ktoś będzie chciał dowiedzieć się więcej, z przyjemnością rozwinę temat.

Send them to us. In December 2014, over 500 books were brought to Chaos Communication Congress in Hamburg for an experiment: During the busy days of Congress, with over 12.000 visitors, how will people react to a library of dead trees? In partnership with La Quadrature Du Thé and the Congress team, a cozy reading area was set up on the fourth floor. For us Dead Tree Lovers, to see all seats and carpet space occupied almost 24/7 by interested readers filled us with delight. The library lives on! And has considerably grown since. The database now contains over 666 titles. As a travelling library, we will bring it to places near you, to hacker events and hackerspaces, to other public spaces. It is currently hosted and accessible around the clock at OpenLab Augsburg, Germany, for free borrowing or cheap purchase, replacing existing books by other used copies. The database is limited in that it does not yet contain all of the historical material that we have so far collected on the earlier days of hacking, pre-80s. Thanks to Werner Pieper, a friend of Wau Holland and publisher, we have started to add rare material from the good old times when hacking was part of the broader political counterculture movement and not yet mainstream. Thanks to the CCC, we are now hosting a complete paper archive of the Chaos Computer Club publication 'Die Datenschleuder'. The Humanistische Union (HU) donated most (all?) of their publications. WE WANT MORE. The library needs your help. Please send us your books and reading suggestions for us to hunt down paper copies! Or better yet, send us offers first. We're open for anything tech, political, scifi, as long as you feel it influenced your life profoundly and is worth reading. The focus is hacker culture and its history in the broader sense. It is not necessary to give your books away forever, we can log the source and return it if and when you want it back. Dead Tree Lovers c/o OpenLab Augsburg e.V.

Welp. ---------- Treść przekazywanej wiadomości ---------- Temat: Re: Hacking Team has been hacked (hard) Data: środa, 8 lipca 2015, 03:29:59 DW: cypherpunks(a)cpunks.org why just the header Rayzer? a guide this good demands completeness --- _ _ _ ____ _ _ | | | | __ _ ___| | __ | __ ) __ _ ___| | _| | | |_| |/ _` |/ __| |/ / | _ \ / _` |/ __| |/ / | | _ | (_| | (__| < | |_) | (_| | (__| <|_| |_| |_|\__,_|\___|_|\_\ |____/ \__,_|\___|_|\_(_) A DIY Guide for those without the patience to wait for whistleblowers --[ 1 ]-- Introduction I'm not writing this to brag about what an 31337 h4x0r I am and what m4d sk1llz it took to 0wn Gamma. I'm writing this to demystify hacking, to show how simple it is, and to hopefully inform and inspire you to go out and hack shit. If you have no experience with programming or hacking, some of the text below might look like a foreign language. Check the resources section at the end to help you get started. And trust me, once you've learned the basics you'll realize this really is easier than filing a FOIA request. --[ 2 ]-- Staying Safe This is illegal, so you'll need to take same basic precautions: 1) Make a hidden encrypted volume with Truecrypt 7.1a [0] 2) Inside the encrypted volume install Whonix [1] 3) (Optional) While just having everything go over Tor thanks to Whonix is probably sufficient, it's better to not use an internet connection connected to your name or address. A cantenna, aircrack, and reaver can come in handy here. [0] https://truecrypt.ch/downloads/ [1] https://www.whonix.org/wiki/Download#Install_Whonix As long as you follow common sense like never do anything hacking related outside of Whonix, never do any of your normal computer usage inside Whonix, never mention any information about your real life when talking with other hackers, and never brag about your illegal hacking exploits to friends in real life, then you can pretty much do whatever you want with no fear of being v&. NOTE: I do NOT recommend actually hacking directly over Tor. While Tor is usable for some things like web browsing, when it comes to using hacking tools like nmap, sqlmap, and nikto that are making thousands of requests, they will run very slowly over Tor. Not to mention that you'll want a public IP address to receive connect back shells. I recommend using servers you've hacked or a VPS paid with bitcoin to hack from. That way only the low bandwidth text interface between you and the server is over Tor. All the commands you're running will have a nice fast connection to your target. --[ 3 ]-- Mapping out the target Basically I just repeatedly use fierce [0], whois lookups on IP addresses and domain names, and reverse whois lookups to find all IP address space and domain names associated with an organization. [0] http://ha.ckers.org/fierce/ For an example let's take Blackwater. We start out knowing their homepage is at academi.com. Running fierce.pl -dns academi.com we find the subdomains: 67.238.84.228 email.academi.com 67.238.84.242 extranet.academi.com 67.238.84.240 mail.academi.com 67.238.84.230 secure.academi.com 67.238.84.227 vault.academi.com 54.243.51.249 www.academi.com Now we do whois lookups and find the homepage of www.academi.com is hosted on Amazon Web Service, while the other IPs are in the range: NetRange: 67.238.84.224 - 67.238.84.255 CIDR: 67.238.84.224/27 CustName: Blackwater USA Address: 850 Puddin Ridge Rd Doing a whois lookup on academi.com reveals it's also registered to the same address, so we'll use that as a string to search with for the reverse whois lookups. As far as I know all the actual reverse whois lookup services cost money, so I just cheat with google: "850 Puddin Ridge Rd" inurl:ip-address-lookup "850 Puddin Ridge Rd" inurl:domaintools Now run fierce.pl -range on the IP ranges you find to lookup dns names, and fierce.pl -dns on the domain names to find subdomains and IP addresses. Do more whois lookups and repeat the process until you've found everything. Also just google the organization and browse around its websites. For example on academi.com we find links to a careers portal, an online store, and an employee resources page, so now we have some more: 54.236.143.203 careers.academi.com 67.132.195.12 academiproshop.com 67.238.84.236 te.academi.com 67.238.84.238 property.academi.com 67.238.84.241 teams.academi.com If you repeat the whois lookups and such you'll find academiproshop.com seems to not be hosted or maintained by Blackwater, so scratch that off the list of interesting IPs/domains. In the case of FinFisher what led me to the vulnerable finsupport.finfisher.com was simply a whois lookup of finfisher.com which found it registered to the name "FinFisher GmbH". Googling for: "FinFisher GmbH" inurl:domaintools finds gamma-international.de, which redirects to finsupport.finfisher.com ...so now you've got some idea how I map out a target. This is actually one of the most important parts, as the larger the attack surface that you are able to map out, the easier it will be to find a hole somewhere in it. --[ 4 ]-- Scanning & Exploiting Scan all the IP ranges you found with nmap to find all services running. Aside from a standard port scan, scanning for SNMP is underrated. Now for each service you find running: 1) Is it exposing something it shouldn't? Sometimes companies will have services running that require no authentication and just assume it's safe because the url or IP to access it isn't public. Maybe fierce found a git subdomain and you can go to git.companyname.come/gitweb/ and browse their source code. 2) Is it horribly misconfigured? Maybe they have an ftp server that allows anonymous read or write access to an important directory. Maybe they have a database server with a blank admin password (lol stratfor). Maybe their embedded devices (VOIP boxes, IP Cameras, routers etc) are using the manufacturer's default password. 3) Is it running an old version of software vulnerable to a public exploit? Webservers deserve their own category. For any webservers, including ones nmap will often find running on nonstandard ports, I usually: 1) Browse them. Especially on subdomains that fierce finds which aren't intended for public viewing like test.company.com or dev.company.com you'll often find interesting stuff just by looking at them. 2) Run nikto [0]. This will check for things like webserver/.svn/, webserver/backup/, webserver/phpinfo.php, and a few thousand other common mistakes and misconfigurations. 3) Identify what software is being used on the website. WhatWeb is useful [1] 4) Depending on what software the website is running, use more specific tools like wpscan [2], CMS-Explorer [3], and Joomscan [4]. First try that against all services to see if any have a misconfiguration, publicly known vulnerability, or other easy way in. If not, it's time to move on to finding a new vulnerability: 5) Custom coded web apps are more fertile ground for bugs than large widely used projects, so try those first. I use ZAP [5], and some combination of its automated tests along with manually poking around with the help of its intercepting proxy. 6) For the non-custom software they're running, get a copy to look at. If it's free software you can just download it. If it's proprietary you can usually pirate it. If it's proprietary and obscure enough that you can't pirate it you can buy it (lame) or find other sites running the same software using google, find one that's easier to hack, and get a copy from them. [0] http://www.cirt.net/nikto2 [1] http://www.morningstarsecurity.com/research/whatweb [2] http://wpscan.org/ [3] https://code.google.com/p/cms-explorer/ [4] http://sourceforge.net/projects/joomscan/ [5] https://code.google.com/p/zaproxy/ For finsupport.finfisher.com the process was: * Start nikto running in the background. * Visit the website. See nothing but a login page. Quickly check for sqli in the login form. * See if WhatWeb knows anything about what software the site is running. * WhatWeb doesn't recognize it, so the next question I want answered is if this is a custom website by Gamma, or if there are other websites using the same software. * I view the page source to find a URL I can search on (index.php isn't exactly unique to this software). I pick Scripts/scripts.js.php, and google: allinurl:"Scripts/scripts.js.php" * I find there's a handful of other sites using the same software, all coded by the same small webdesign firm. It looks like each site is custom coded but they share a lot of code. So I hack a couple of them to get a collection of code written by the webdesign firm. At this point I can see the news stories that journalists will write to drum up views: "In a sophisticated, multi-step attack, hackers first compromised a web design firm in order to acquire confidential data that would aid them in attacking Gamma Group..." But it's really quite easy, done almost on autopilot once you get the hang of it. It took all of a couple minutes to: * google allinurl:"Scripts/scripts.js.php" and find the other sites * Notice they're all sql injectable in the first url parameter I try. * Realize they're running Apache ModSecurity so I need to use sqlmap [0] with the option --tamper='tamper/modsecurityversioned.py' * Acquire the admin login information, login and upload a php shell [1] (the check for allowable file extensions was done client side in javascript), and download the website's source code. [0] http://sqlmap.org/ [1] https://epinna.github.io/Weevely/ Looking through the source code they might as well have named it Damn Vulnerable Web App v2 [0]. It's got sqli, LFI, file upload checks done client side in javascript, and if you're unauthenticated the admin page just sends you back to the login page with a Location header, but you can have your intercepting proxy filter the Location header out and access it just fine. [0] http://www.dvwa.co.uk/ Heading back over to the finsupport site, the admin /BackOffice/ page returns 403 Forbidden, and I'm having some issues with the LFI, so I switch to using the sqli (it's nice to have a dozen options to choose from). The other sites by the web designer all had an injectable print.php, so some quick requests to: https://finsupport.finfisher.com/GGI/Home/print.php?id=1 and 1=1 https://finsupport.finfisher.com/GGI/Home/print.php?id=1 and 2=1 reveal that finsupport also has print.php and it is injectable. And it's database admin! For MySQL this means you can read and write files. It turns out the site has magicquotes enabled, so I can't use INTO OUTFILE to write files. But I can use a short script that uses sqlmap --file-read to get the php source for a URL, and a normal web request to get the HTML, and then finds files included or required in the php source, and finds php files linked in the HTML, to recursively download the source to the whole site. Looking through the source, I see customers can attach a file to their support tickets, and there's no check on the file extension. So I pick a username and password out of the customer database, create a support request with a php shell attached, and I'm in! --[ 5 ]-- (fail at) Escalating ___________ < got r00t? > ----------- \ ^__^ \ (oo)\_______ (__)\ )\/\ ||----w | || || ^^^^^^^^^^^^^^^^ Root over 50% of linux servers you encounter in the wild with two easy scripts, Linux_Exploit_Suggester [0], and unix-privesc-check [1]. [0] https://github.com/PenturaLabs/Linux_Exploit_Suggester [1] https://code.google.com/p/unix-privesc-check/ finsupport was running the latest version of Debian with no local root exploits, but unix-privesc-check returned: WARNING: /etc/cron.hourly/mgmtlicensestatus is run by cron as root. The user www-data can write to /etc/cron.hourly/mgmtlicensestatus WARNING: /etc/cron.hourly/webalizer is run by cron as root. The user www-data can write to /etc/cron.hourly/webalizer so I add to /etc/cron.hourly/webalizer: chown root:root /path/to/my_setuid_shell chmod 04755 /path/to/my_setuid_shell wait an hour, and ....nothing. Turns out that while the cron process is running it doesn't seem to be actually running cron jobs. Looking in the webalizer directory shows it didn't update stats the previous month. Apparently after updating the timezone cron will sometimes run at the wrong time or sometimes not run at all and you need to restart cron after changing the timezone. ls -l /etc/localtime shows the timezone got updated June 6, the same time webalizer stopped recording stats, so that's probably the issue. At any rate, the only thing this server does is host the website, so I already have access to everything interesting on it. Root wouldn't get much of anything new, so I move on to the rest of the network. --[ 6 ]-- Pivoting The next step is to look around the local network of the box you hacked. This is pretty much the same as the first Scanning & Exploiting step, except that from behind the firewall many more interesting services will be exposed. A tarball containing a statically linked copy of nmap and all its scripts that you can upload and run on any box is very useful for this. The various nfs-* and especially smb-* scripts nmap has will be extremely useful. The only interesting thing I could get on finsupport's local network was another webserver serving up a folder called 'qateam' containing their mobile malware. --[ 7 ]-- Have Fun Once you're in their networks, the real fun starts. Just use your imagination. While I titled this a guide for wannabe whistleblowers, there's no reason to limit yourself to leaking documents. My original plan was to: 1) Hack Gamma and obtain a copy of the FinSpy server software 2) Find vulnerabilities in FinSpy server. 3) Scan the internet for, and hack, all FinSpy C&C servers. 4) Identify the groups running them. 5) Use the C&C server to upload and run a program on all targets telling them who was spying on them. 6) Use the C&C server to uninstall FinFisher on all targets. 7) Join the former C&C servers into a botnet to DDoS Gamma Group. It was only after failing to fully hack Gamma and ending up with some interesting documents but no copy of the FinSpy server software that I had to make due with the far less lulzy backup plan of leaking their stuff while mocking them on twitter. Point your GPUs at FinSpy-PC+Mobile-2012-07-12-Final.zip and crack the password already so I can move on to step 2! --[ 8 ]-- Other Methods The general method I outlined above of scan, find vulnerabilities, and exploit is just one way to hack, probably better suited to those with a background in programming. There's no one right way, and any method that works is as good as any other. The other main ways that I'll state without going into detail are: 1) Exploits in web browers, java, flash, or microsoft office, combined with emailing employees with a convincing message to get them to open the link or attachment, or hacking a web site frequented by the employees and adding the browser/java/flash exploit to that. This is the method used by most of the government hacking groups, but you don't need to be a government with millions to spend on 0day research or subscriptions to FinSploit or VUPEN to pull it off. You can get a quality russian exploit kit for a couple thousand, and rent access to one for much less. There's also metasploit browser autopwn, but you'll probably have better luck with no exploits and a fake flash updater prompt. 2) Taking advantage of the fact that people are nice, trusting, and helpful 95% of the time. The infosec industry invented a term to make this sound like some sort of science: "Social Engineering". This is probably the way to go if you don't know too much about computers, and it really is all it takes to be a successful hacker [0].

This includes familiarity with the windows command prompt and unix shell, basic scripting skills, knowledge of ldap, kerberos, active directory, networking, etc. --[ 10 ]-- Outro You'll notice some of this sounds exactly like what Gamma is doing. Hacking is a tool. It's not selling hacking tools that makes Gamma evil. It's who their customers are targeting and with what purpose that makes them evil. That's not to say that tools are inherently neutral. Hacking is an offensive tool. In the same way that guerrilla warfare makes it harder to occupy a country, whenever it's cheaper to attack than to defend it's harder to maintain illegitimate authority and inequality. So I wrote this to try to make hacking easier and more accessible. And I wanted to show that the Gamma Group hack really was nothing fancy, just standard sqli, and that you do have the ability to go out and take similar action. Solidarity to everyone in Gaza, Israeli conscientious-objectors, Chelsea Manning, Jeremy Hammond, Peter Sunde, anakata, and all other imprisoned hackers, dissidents, and criminals! ----------------------------------------- -- Pozdrawiam, Michał "rysiek" Woźniak Zmieniam klucz GPG :: http://rys.io/pl/147 GPG Key Transition :: http://rys.io/en/147

longblob w mysql - good practices for a bad practice? :]
by spin＠hackerspace.pl 13 Jul '15

13 Jul '15

in b4 na longbloby jest baza danych i nazywa się filesystem - tak wiem o tym. Mimo to chciałem pobawić się pakowaniem danych binarnych w DB, bo ma to parę zalet. Jakie są good practices trzymania i adresowania longblobów w MySQL (poza 'don't fuckin' do it')? Wiem że Microsoft coś kombinował z wydajnością tego, i InnoDB coś tam miało swojego, a Oracle zostawał w tyle... Dorobili się czegoś, jest coś w planach, są obejścia/hax, czy zlać MySQLa i pójść gdzie indziej? Jak trzymać w bazie dane dłuższe niż 4gb? Concat z kilku regionów? Jak adresować longbloby typu video, które mogą być streamowane i mają czas trwania, więc wywołąnie może być fragmentaryczne? Ew. inne ciekawe case'y, dawajcie mi, ponieważ mój mózg om nom nom je z chęcią. Again, wiem że pakowanie longblobów do bazy danych jest bad practice, ale ma kilka zalet które mnie interesują i chciałem się pobawić.

Oy. Potrzebuję rekomendacji na płytę główną do domowego NASa. Must have: Procesor zintegrowany, minimum 6 portów SATA, luniks-friendly. Bonusy: Mały form factor, energooszczędna, fajnie jeśli pasywny radiator. Będzie pewnie robiła enkrypcję, pewnie luks, więc byłoby megamiło gdyby proc dał rade bez gotowania wątróbki. Chyba że ktoś ma fajne rozwiązania na client-side decrypt, to z chęcią poznam :) Ktoś coś mógłby polecić?

trawienie ribbon cables/flexPCBs

Yo, potrzebuję wytrawić ścieżki na czymś giętkim. Wiem że jest kapton powlekany miedzią od 3M, ale jest trudny do dostania. Plz opinie czy dałoby radę zkleić cienką folię miedzianą z taśmą kaptonową i tak trawić. Co z reaktywnością kleju? Taśmy miedziane widziałem tylko powlekane klejem, ktoś z tym pracował? Jak to się zachowuje w lutowaniu? etc. Sugestie/opinie mile widziane. Ew. jak ktoś ma odrobinę folii miedzianej żebym nie musiał kupować całej rolki, to bym na kapton nalepił i przetrawił, przelutował, ztestował. Jak nie da rady to wezmę zwykłą taśmę AWG28 ale wolałbym tego uniknąć, bo będzie nieelegancko.

Fwd: [Cryptography] Did Intel just execute its warrant canary ?
by rysiek 11 Jun '15

---------- Treść przekazywanej wiadomości ---------- Temat: Fwd: [Cryptography] Did Intel just execute its warrant canary ? Data: wtorek, 9 czerwca 2015, 01:01:44 From: Henry Baker [via garpgarp] FYI -- I conjecture that the second GPU story following less than one month after the first GPU story is not just coincidence, but one of the requirements of a secret National Security Letter to Intel. The first story shows how GPU's can house malware, while the second story explains that Intel won't be sharing its GPU code where such malware will be housed. "no reverse engineering, decompilation, or disassembly of this software is permitted" As feared, the DMCA will be used against those who attempt to look for this malware in Intel GPU's. https://en.wikipedia.org/wiki/Digital_Millennium_Copyright_Act -------- http://arstechnica.com/security/2015/05/gpu-based-rootkit-and-keylogger-off… GPU-based rootkit and keylogger offer superior stealth and computing power Proof-of-concept malware may pave the way for future in-the-wild attacks. by Dan Goodin - May 7, 2015 3:43 pm UTC Developers have published two pieces of malware that take the highly unusual step of completely running on an infected computer's graphics card, rather than its CPU, to enhance their stealthiness and give them increased computational abilities. Both the Jellyfish rootkit and the Demon keylogger are described as proofs-of-concept by their pseudo-anonymous developers, whom Ars was unable to contact. Tapping an infected computer's GPU allows malware to run without the usual software hooks or modifications malware makes in the operating system kernel. Those modifications can be dead giveaways that a system is infected. https://github.com/x0r1/jellyfish https://github.com/x0r1/Demon Here's how the developers describe their rootkit: Jellyfish is a Linux based userland gpu rootkit proof of concept project utilizing the LD_PRELOAD technique from Jynx (CPU), as well as the OpenCL API developed by Khronos group (GPU). Code currently supports AMD and NVIDIA graphics cards. However, the AMDAPPSDK does support Intel as well. Advantages of gpu stored memory: * No gpu malware analysis tools available on web * Can snoop on cpu host memory via DMA * Gpu can be used for fast/swift mathematical calculations like xor'ing or parsing * Stubs * Malicious memory is still inside gpu after shutdown Requirements for use: * Have OpenCL drivers/icds installed * Nvidia or AMD graphics card (intel supports amd's sdk) * Change line 103 in rootkit/kit.c to server ip you want to monitor gpu client from Stay tuned for more features: * client listener; let buffers stay stored in gpu until you send magic packet from server Disclaimer: Educational purposes only; authors of this project/demonstration are in no way, shape or form responsible for what you may use this for whether illegal or not. They provide no technical details about Demon keylogger other than to say it's a proof-of-concept that implements the malware described in this 2013 academic research paper titled You Can Type, but You Can’t Hide: A Stealthy GPU-based Keylogger. The Demon creators stress that they aren't associated with the researchers. http://www.cs.columbia.edu/~mikepo/papers/gpukeylogger.eurosec13.pdf "The key idea behind our approach is to monitor the system’s keyboard buffer directly from the GPU via DMA [direct memory access], without any hooks or modifications in the kernel's code and data structures besides the page table," the researchers behind the 2013 paper wrote. "The evaluation of our prototype implementation shows that a GPU-based keylogger can effectively record all user keystrokes, store them in the memory space of the GPU, and even analyze the recorded data in-place, with negligible runtime overhead." Aside from malware that taps GPUs to mint Bitcoin and other crypto currencies, Ars isn't aware of malicious software actively circulating in the wild that makes use of infected computers' graphics processors. And even then, most or all of those titles run mainly on the CPU and offload only the computationally intensive workloads to the GPU. In March, researchers from Kaspersky Lab documented highly sophisticated malware in the wild that infected firmware that runs 12 different models of hard drives. The group that created the malware had flown under the radar for 14 years. In its current form Jellyfish is likely to remain a highly niche undertaking, since it requires a dedicated GPU. Since many computers don't contain stand-alone graphics cards, such malware might greatly limit the machines that could be infected. Still, the approach may make sense in certain situations, say for attackers targeting gamers or video enthusiasts, or espionage campaigns where stealth is crucial. And as readers have pointed out in comments below, it's feasible malware could be developed that runs on graphics processors integrated into CPUs. Post updated to recast the last paragraph to account for integrated graphics processors, and to add details in the second-to-last paragraph about malware infecting hard-drive firmware. ---------------- https://www.phoronix.com/scan.php?page=news_item&px=Intel-SKL-BXT-Firmware-… Intel Skylake & Broxton To Require Graphics Firmware Blobs Published on 05 June 2015 06:20 PM EDT Written by Michael Larabel in Intel Intel's upcoming Skylake and Broxton hardware will require some binary-only firmware blobs by the i915 DRM kernel graphics driver. Rodrigo Vivi of Intel's Open-Source Technology Center sent in the pull request for landing these binary files into the linux-firmware repository. Up to now there's been no i915 blobs within the linux-firmware tree. These first i915 DRM firmware blobs are for Skylake and Broxton for the GuC and DMC. DMC in this context is the Display Microcontroller, which is present in Skylake (Gen9) and newer and used within the display engine to save and restore its state when entering into low-power states and then resuming. The DMC is basically saving/restoring display registers across low-power states separate of the kernel. The GuC engine on Skylake is responsible for workload scheduling on the parallel graphics engines. Intel explained on 01.org, "GuC is designed to perform graphics workload scheduling on the various graphics parallel engines. In this scheduling model, host software submits work through one of the 256 graphics doorbells and this invokes the scheduling operation on the appropriate graphics engine. Scheduling operations include determining which workload to run next, submitting a workload to a command streamer, pre-empting existing workloads running on an engine, monitoring progress and notifying host SW when work is done." This page also seems to indicate that these firmware blobs are required by the DRM driver rather than being an optional add-on. The license of these firmware blobs also indicate that redistribution is only allowed in binary form without modification. Beyond that, "no reverse engineering, decompilation, or disassembly of this software is permitted." These new firmware blobs will certainly have some open-source enthusiasts less excited now about Skylake, Broadwell's successor beginning to ship later this year, and Broxton meanwhile is the new Atom SoC built using the Goldmont architecture and will feature Skylake graphics. If there's any good news out of the situation, at least Intel is shipping these firmware files early rather than NVIDIA that with their months-old hardware still hasn't released their GTX 900 Maxwell firmware files needed by the Nouveau driver to provide open-source hardware acceleration. AMD also tends to be timely with the releasing of their necessary binary-only GPU firmware files for the open-source Linux driver. _______________________________________________ The cryptography mailing list cryptography(a)metzdowd.com http://www.metzdowd.com/mailman/listinfo/cryptography ----------------------------------------- -- Pozdrawiam, Michał "rysiek" Woźniak Zmieniam klucz GPG :: http://rys.io/pl/147 GPG Key Transition :: http://rys.io/en/147

Próbowałem mini-jackiem, próbowałem cinchami w Component i w S-Video, ni chu. Twierdzi, że "no connection". Jeszcze może spróbuję przejściówkę S-Video<->SCART. Ale może jest coś, co mi umyka?
