The use-after-free vulnerability, CVE 2015-0313, was patched by Adobe on Feb. 2, and the attack campaign came to a screeching halt. The attackers injected the malware-ridden ads on the websites of Dailymotion, Huffington Post, answers.com, New York Daily News, HowToGeek.com and tagged.com. Malwarebytes doesn’t have a head count of victims hit with the ransomware, but traffic to the infected sites reached over 1 billion in February of this year.”]
