Questions left unanswered about Yahoo malware attack
On Saturday, Fox IT, a security firm in the Netherlands, discovered that some visitors to Yahoo.com over the last few days have been infected with malware. Visitors to pages with malicious ads were redirected to sites armed with code that exploits vulnerabilities in Java and installs a variety of different malware.
Following news of the exploit, Yahoo has issued two statements to the press, but so far nothing on its public Tumblr blog, where it provides updates on products and services. On Saturday, a Yahoo spokesperson said:
"At Yahoo, we take the safety and privacy of our users seriously. We recently identified an ad designed to spread malware to some of our users. We immediately removed it and will continue to monitor and block any ads being used for this activity." On Sunday, Yahoo offered a few more details, notably that the exploit impacted European users, and that Macintosh and mobile users were safe.
