Java Zero Day Exploit Leveraged In Targeted Attack Campaign: Symantec [UPDATED]

Posted in Commentary with tags , , on September 1, 2012 by itnerd

You might recall that I have talked about a serious Java exploit that currently has no fix. According to Symantec, the news just got worse. Here’s a quote from a e-mail that Symantec sent me:

In October 2011, Symantec published a paper [Warning: PDF] on The Nitro Attacks targeting chemical companies. These targeted attacks were in the form of an email with a malicious attachment ultimately leading to victims being infected with ‘Poison Ivy’. No vulnerabilities were exploited in these attacks. The recent attacks by this group are more sophisticated, using a Java zero-day vulnerability to infect victims but using the same IP address for the command and control server that was used in 2011.

Well, that’s just delightful. The full details can be found here. But it shows that Oracle needs to step up to the plate and fix this exploit. Until that happens, either downgrade to Java 1.6 (if you must have Java) or disable it entirely.

UPDATE: Apparently there is an update from Oracle that addresses this issue. Check their download page here. It would have been nice if Oracle had said something about this as apparently these have been out since Thursday. Sure they put out something on their blog. But given how serious this was, you’d think they’d make a bit more noise. In any case. Download those updates and protect yourself.

New Java Exploit Is A Threat To You…. Regardless Of What OS You Run [UPDATED]

Posted in Commentary with tags , on August 28, 2012 by itnerd

There’s a new Java vulnerability that has been discovered which poses a significant threat to systems running Java 7 update 6. In other words, the most recent version. It doesn’t matter if you run Windows, OS X, or LINUX. It affects them all. Details can be found on this blog post. I should note that Oracle is moving to a quarterly update cycle for Java, meaning that the next regularly-scheduled update to Java SE 7 is not planned until October. That’s a problem as there is no fix for this. So how do you protect yourself? Turn off Java until Oracle comes out with a fix.

UPDATE: Unsure if you’re affected? Check out this website which will see if you, your version of Java and your browser is exploitable. Then check out this site to see how to protect yourself.

Java For Mac Installer Appears On Java Website….. Mac Users Should Care

Posted in Commentary with tags , on August 26, 2012 by itnerd

Up until this past week, the only way you could get Java on your Mac was to get it through Apple. Not the worst thing in the world except for the fact that it wasn’t updated as frequently as Java versions on other platforms. That opened half a million Macs up to being infected by the Flashback Trojan. Not good. After that episode, Java support moved to being supported and updated by Oracle. That means that something like the Flashback Trojan is much less likely to happen because any vulnerabilities would be closed quickly which means that exploits like the Flashback Trojan would have a very short shelf life.

So, if you want Java for Mac and you’re running OS X Lion or Mountain Lion, you can get it here. You might want to read this before installing it though. All of that of course assumes you need Java. Most users don’t. But if you do, you should really update now.

Java Hole On Mac FINALLY Fixed

Posted in Commentary with tags , , on June 17, 2009 by itnerd

This is a bit late, but I just wanted to do a quick post about the fact that the Java hole that Apple left unpatched for months is finally fixed in Tiger (OS 10.4) and Leopard (OS 10.5). Users should go to the link for their OS or simply use software update to get their copy of the update.

While it is nice that Apple is finally releasing an update to Java 6 which matches up with Sun’s 13 build. It would have been nice to get to the 14 build from Sun which has the new G1 garbage collection and compressed 64 bit pointers. Both of which gets you much better memory usage. But in any case, it’s nice to have a version of Java that has no (known) holes.
