Europe users clicking on had a good chance of having their computers infected with malware from malicious ads over a four-day time frame.

Cybercriminals were able to place compromised as early as December 30, said researchers at security firm Fox-IT. Malicious iframes placed on the website redirected users to domains hosting the Magnitude exploit kit.

The exploit kit leveraged Java vulnerabilities to push various pieces of malware, including ZeuS, Andromeda, Dorkbot, Tinba (Zusy), and Necurs.

Yahoo said users from Europe are the only ones that can suffer from the issue. Fox-IT said most infections were in Romania, the UK, and France.

Yahoo cleared up the problem by January 3. However, researchers from HitmanPro said there could be as much as 2.5 million computers infected with the malware.

The victims did not have to click on the malicious ads in order to have their devices infected with malware. Users from Europe who visited from a computer running a vulnerable version of Java should immediately scan their computers with an up-to-date antivirus program to make sure they’re not a victim of the attack.
