Microsoft has highlighted an "unprecedented" wave of attacks aimed at Java over the past three months.
Attacks on Java vulnerabilities have increased from fewer than 500,000 in the second quarter of 2010 to over six million this quarter, according to Holly Stewart of the Microsoft Malware Protection Center.
"What I discovered was that some of our exploit 'malware' families were telling a scary story: an unprecedented wave of Java exploitation," she warned in a blog post.
Exploited holes in Java are now outpacing attacks on PDFs, Stewart said. The bulk of attacks are via three security holes in Java, all of which were patched some time ago and are only successful because users are not updating third-party applications.
