Blackhole Author Created Premium 'Cool' Exploit Kit
The author of Blackhole is said to also be behind the creation of the Cool Exploit Kit, a premium attack toolkit that was purportedly once rented at $10,000 a month. When it was released in January, the kit was advertised as having highly sought-after exploits that target zero-day vulnerabilities. A review of the Cool toolkit conducted by Microsoft in May found the kit contained six exploits, including one Java zero-day flaw at the time. It's also believed to have fueled an increase in ransomware malware.
