Symantec Intelligence Report: July 2011

Jul 26, 2011

0 comments

With one in 280.9 emails identified as malicious in July, further analysis reveals a significant increase in activity related to what may be described as an aggressive and rapidly changing form of generic polymorphic malware (polymorphic malware may have many variations of the same code using different encoding techniques, but the functionality of the program remains the same in each version). This rise accounted for 23.7 percent of all email-borne malware intercepted in July; more than double the same figure six months ago, indicating a much more aggressive strategy on the part of the cyber criminals responsible, perhaps greater use of automation has enabled them to increase their output to this extent.

In the same time frame, the number of variants, or different strains of malware involved in each attack has also grown dramatically by a factor of 25 times the same quantity six months previously; an alarming proliferation in such a short time almost certainly heightens the risk profiles of many organizations as these new strains are much harder to detect using traditional security defenses. This new breed of malware is likely to be causing a great deal of pain for a great number of traditional anti-virus companies that rely on signatures, heuristics and software emulation in order to detect malicious activity.
