Security researchers have discovered a highly nasty Linux trojan that has
been used by cybercriminals in state sponsored attack in order to steal
personal, confidential information from government institutions, military and
pharmaceutical companies around the world.
A previously unknown piece of a larger puzzle called "Turla," one of the most
complex Advanced Persistent Threats (APTs) uncovered by researchers at
Kaspersky Lab in August, remained hidden on some systems for at least four
years. The malware was notable for its use of a rootkit that made it extremely
hard to detect.
The German security company G Data believed that Turla campaign is linked to
Russia and has in the past exploited a variety of Windows vulnerabilities, at
least two of which were zero-days, to infect government institutions,
embassies, military, education, research, and pharmaceutical companies in more
than 45 countries.
Recently, security researchers from Moscow-based Kaspersky Lab have detected
the first Turla sample targeting Linux operating system. This Linux component
of malware points towards a much bigger threat than it was previously thought
and it may also herald the discovery of more infected systems.
"The newly discovered Turla sample is unusual in the fact that it's the
first Turla sample targeting the Linux operating system that we have
discovered," Kaspersky researcher Kurt Baumgartner said in an advisory. "We
suspect that this component was running for years at a victim site, but do not
have concrete data to support that statement just yet."
The modules of the Linux-based Turla malware is written in C and C++ languages
and contains code from previously written libraries. The malware uses hidden
network communication and stripped of symbol information, which makes it hard
for researchers to reverse engineer or analyze.
As a result, the Linux-based Turla trojan may have capabilities that have not
yet been uncovered completely, as Baumgartner said the Linux component is a
mystery even after its discovery, adding it can't be detected using the common
Netstat command.
In order to hide itself, the backdoor sits inactive until hackers send it
unusually crafted packets that contain "magic numbers" in their sequence
numbers. The malware have ability to sit unnoticed on victims computers for
years. The trojan contained attack functionalities including arbitrary remote
command execution, incoming packet interception and remote management even
though it requires no root system privileges.
Earlier this year, Kaspersky Labs researches suggested Turla as Snake, which
was built on the capabilities of Agent.Biz, the worm that came to the surface
in 2008 when US Department of Defense sources claimed that its classified
networks had been breached by an early version of the same virus, described by
officials as the "worst breach of US military computers in history." Uroburos
rootkit was also one of the components of Snake campaign.
Agent.Biz has since been developed with many advanced features that make it
even more flexible and sophisticated than before. It was thought to have
inspired other nasty malware creations including Flame and Guass.
