[tweetmeme source=”franscomputerservices” only_single=false]Unpatch Java Exploit Spotted in-the-wild (Krebs on Security):
Last week, a Google security researcher detailed a little-known feature built into Java that can be used to launch third-party applications. Today, security experts unearthed evidence that a popular song lyrics Web site was compromised and seeded with code that leverages this Java feature to install malicious software.
As I mentioned last time, it is sad that Java is needed to help keep your systems safer through Secunia’s OSI (Online Software Inspector) by helping you keep your Internet facing programs up to date.
For now, if you are not sure if you have Java on your system, you can look in Add/Remove Programs (Windows XP) or Programs, Uninstall Programs (Vista and Windows 7) to see if it is installed. The best option at this point is to probably uninstall Java entirely on Windows computers until Oracle realizes the dangers this problem poses to Windows users.
Of course if you would prefer, you could use the link to SANS Internet Storm Center (New bug/exploit for javaws) to review your options.
However, note that there is still the possibility that the malware cocktail could still potentially gain access through Internet Explorer even if you are not using Internet Explorer. To prevent this, Windows users might consider installing BillP Studios’ WinPatrol so they are alerted to any changes to their system before it happens and be given an opportunity to prevent it – You can try it out for free, but it is one of the best $19.99 you ever spent ($10 off right now, normal price $29.99). BillP Studios used to have a free version which can still be found on sites like FileHippo.com (note, however that it is not the new version which is apparently only offered in Trial/Buy).
According to the article, popular lyrics site: songlyrics dot com (I did not create a link to it and I would NOT recommend going there if you have Java installed!) the “Crimepack” exploit kit is being used to foist a cocktail of malware on Windows users’ computers.
I mentioned this Java vulnerability in my last posting. If you want more information, please see my earlier post and Brian Kreb’s Krebs on Security article above.
Tavis Ormand tried to get through to Oracle about the danger, but they chose to rate it as not that important. They indicated that it could wait till the normal patch cycle. However, apparently, they didn’t fix it then either because when all the Oracle quarterly cycle patches came out this week it wasn’t in their list of fixed vulnerabilities — which means they apparently intend to wait till the NEXT cycle!
Roger Thompson, chief research officer at AVG says:
the site appears to use the very same code mentioned in Ormandy’s proof-of-concept to silently redirect songlyrics.com visitors to a site that loads the “Crimepack” exploit kit, a relatively new kit designed to throw a heap of software exploits at visiting browsers…
It is hard to say whether visiting sites like the lyrics site would hurt other OSes like Mac OS X (especially Tiger which hasn’t had a Java update in ages!), or Linux because Brian Krebs’ article was geared to Windows users.
