Details of malware to be discussed at VB2015.
Researchers at
Check Point
have
revealed
details of a cyber-espionage campaign, dubbed ‘Volatile Cedar’, that has been active since at least 2012.
The campaign, whose motive appears to be political rather than financial, revolves around a custom-made remote access trojan named ‘Explosive’, which is separated into a main binary and a DLL file.
This separation allows the attacker to quickly patch the trojan, both to update functionality and to avoid heuristic detection. Indeed, it appears that every time the malware started to become detectable by anti-virus solutions, a new version was created. The most recent version is still active.
To control the infected machines, Explosive’s authors set up a command and control (C&C) infrastructure which includes both static and dynamic C&C servers, the latter using domain generation algorithms.
Explosive’s rather complex communication schema.
Targets of the campaign appear to be carefully selected, and based on these as well as some circumstantial evidence, the researchers believe the attacker group to be based in Lebanon and to have political ties.
Interestingly, rather than using spear phishing, as is common among so-called APT attacks, Explosive’s initial targets were public-facing
Windows
servers. From there, attackers would look for further targets on the same internal network.
Full details on the malware can be found in a technical report (

) published by
Check Point
, while researchers from
Kaspersky Lab
wrote a
blog post
on their findings based on sinkholing the malware.
This campaign will also be the subject of the presentation ‘
The Unbearable Lightness of APTing
‘ at VB2015, the
programme
for which we announced yesterday. VB2015 takes place 30 September to 2 October in Prague, Czech Republic. Registration for the conference will open soon.
