Trusted DesignThe year is 2015 and a threat actor is using the defunct Blackhole exploit kit in active drive-by download campaigns via compromised websites. We noticed Java and PDF exploits collected by our honeypot which we haven’t seen in ages. Looking closer at the structure of this attack, we were surprised when we realized this was the infamous Blackhole. Blackhole’s author, Paunch, was arrested in October 2013 and while criminals kept using the kit for the next few months, the exploits slowly deprecated and lost value because of lack of development. The new drive-by download attacks we caught over the weekend rely on the same structure as the original Blackhole, even reusing the old PDF and Java exploits. The only difference is the malware payload being dropped, which is current and had very low detection on VirusTotal.
