A Tidal Wave of Java Flaw Exploitation

tsu doh nimh writes "Microsoft warned today that it is witnessing a huge spike in the exploitation of Java vulnerabilities on the Windows platform, and that attacks on Java security holes now far outpace the exploitation of Adobe PDF bugs. The Microsoft announcement cites research by blogger Brian Krebs, who has been warning for several months that Java vulnerabilities are showing up as the top moneymakers for those peddling commercial crimeware exploitation kits, such as Eleonore, Crimepack and SEO Sploit Pack." Several days ago, Oracle released a patch that fixed 29 Java security flaws.

    The one question this article doesn't really clarify is pretty important: How are these exploits being loaded onto the user's computer?

    Are we talking applets, Java web start, or some other mechanism?

      Propagation generally happens via applets, loaded through IFRAMEs or Javascript-based redirects. Actual payloads are not yet OS-agnostic (even though the exploits themselves are).

      After further research. It appears that Oracle/Sun latest version of Java addressed these issues for the Windows and Linux platforms. This looks like a case of people not updating their Java JRE.

      It sandboxes Java and Flash until we tell them to run, too.

      You're saying two different things in this sentence, only one of which is true. NoScript does only load plugins if you click on them (assuming it's configured to do so), but it does not "sandbox" plugins in any way. If you allow a malicious object to be loaded in a plugin (such as by clicking on it), NoScript does nothing to stop it.

    For reasons I have never been able to figure out, Java has significant issues auto updating on all my home Windows computers (XP, Vista, and 7). Sure enough, just last week I had to spend a night sanitizing one of the systems, for now I've uninstalled Java until I have the chance to figure out just what the problem is but honestly not having it hasn't been a problem so I'll probably just leave it off until I find something that actually requires it.

  5. Re:Patches have been available for a long time by Florian+Weimer · · Score: 4, Interesting

    Java updates contain unrelated bugfixes and functionality, breaking applications. They are far from being minimal updates. Back in the Sun days, this was addressed by enabling parallel installation of many JVM versions. It was even possible for web content to request a specific JVM version, which means that you actually had to update to a newer version and delete all the old versions. I'm not complete sure that this part has actually been addressed. It's certainly a problem for those who still need to use Java 1.4 or Java 5 (which are out of security support now, but are still widely mandated in the industry).

    I'm still in the process of repairing my Windows system after a Java-transmitted virus. A hacked website was sending out malware to visitors via Java applet, and the only solution I found was a format/reinstall. Since then, I've disabled Java on all my machines; the only things I've seen it used for are crappy browser games and malware.

    There are maybe 3 major versions of Java still in somewhat standard use: 1.4, 1.5, and 1.6. Unless the application in question has some very specific quirks, users should always be able to use the latest and greatest version of 1.6 to run them. The allowance for using older versions of the platform is a feature, not a hindrance.

    It means that if I want to use "BadSoftwareCompany"'s piece of java software, I'm not confined with downloading and breaking my host's latest version of the java if their code only works with 1.4 or 1.5. If I didn't have the feature, I just couldn't use the software without a huge head-ache. To assume that every version of every software will work forever is delusional, but at least there are facilities to support the older tech.

    He seemed pretty accurate other than some exaggeration. If you want to see a "Massive amount of crapware" buy a PC from a big box store, not "java tried to install the yahoo toolbar boo hoo".

    The funniest Java related thing I've seen, is amongst the non-computer cow orkers "Oh man, another java program, that thing is gonna be slow and take IT forever to install (actually they mean the JVM) and crash all the time". Computer people have known that for over a decade now, the funny part is hearing non computer people start to complain.
