Green Lambert

Description

(Kaspersky) Looking further for malware similar to Blue Lambert, we came by another family of malware we called Green Lambert. Green Lambert is a lighter, more reliable, but older version of Blue Lambert. Interestingly, while most Blue Lambert variants have version numbers in the range of 2.x, Green Lambert is mostly in 3.x versions. This stands in opposition to the data gathered from export timestamps and C&C domain activity that points to Green Lambert being considerably older than the Blue variant. Perhaps both Blue and Green Lamberts have been developed in parallel by two different teams working under the same umbrella, as normal software version iterations, with one seeing earlier deployment than the other.

Signatures created for Green Lambert (Windows) have also triggered on an OS X variant of Green Lambert, with a very low version number: 1.2.0. This was uploaded to a multiscanner service in September 2014. The OS X variant of Green Lambert is in many regards functionally identical to the Windows version, however it misses certain functionality such as running plugins directly in memory.
