Some visitors to several high-profile websites last week were redirected to browser exploits that installed malware on their computers because of malicious advertisements on those sites.
Yahoo said that malware spread by advertisements served by its European websites had not affected users in North America, Asia Pacific and Latin America as people in these locations were not served the advertisements.
Malicious ads served through Yahoo's ad network delivered malware to thousands of site visitors, according to researchers at Fox-IT, but Yahoo subsequently blocked the attack.
Russian authorities have arrested the main developer of the notorious Blackhole exploit kit, one of the most popular attack tools used to infect Web users with malware.
The spike in the number of clients using the Tor anonymity network was likely caused by a botnet, according to Tor and third-party security researchers.
