Yahoo Ads Hack Spreads Malware

Millions of users exposed to drive-by malware attacks that targeted Java bugs to install six types of malicious code

Yahoo.com visitors received an unexpected surprise beginning on New Years Eve: advertisements that targeted their systems with malware.
The malicious advertising campaign was first spotted on Friday by Dutch information security consulting firm Fox-IT, which immediately warned Yahoo. Fox-IT said in a blog post that the attack advertisements -- which were being served by ads.yahoo.com -- used iFrames to hide malicious scripts. If a user clicked on the advertisement, they were redirected to a site that hosted the Magnitude exploit kit, which then attempted to exploit any Java vulnerabilities present on their system to install malware.
The attackers are clearly financially motivated and seem to offer services to other actors, said Fox-IT, noting that the exploit kit behind the attacks dropped six different types of malware, including the Zeus banking Trojan, Dorkbot, and a click-fraud Trojan. The greatest number of users targeted by the malicious advertisements were in Romania (24%), the United Kingdom (23%), and France (20%), according to Fox-IT.
