Using our monitoring infrastructure, we conducted an
experiment targeting the malware family DirtJumper
(also known as Ruskill). Between October 2011 and January
2012, the system downloaded a total of 465 malware
samples from VirusTotal [9] following the reference
detection of Microsoft with their virus name Dishigy.B.
Table 1 shows the number of samples with the according
detection first seen at VirusTotal per month.
