Java-based malware driving DDoS botnet infects Windows, Mac, Linux devices

Java-based malware driving DDoS botnet infects Windows, Mac, Linux devices | 21st Century Learning and Teaching | Scoop.it
From arstechnica.com - January 29, 2014 10:34 AM
Multi-platform threat exploits old Java flaw, gains persistence.

 

Researchers have uncovered a piece of botnet malware that is capable of infecting computers running Windows, Mac OS X, and Linux that have Oracle's Java software framework installed.

 

The cross-platform HEUR:Backdoor.Java.Agent.a, as reported in a blog post published Tuesday by Kaspersky Lab, takes hold of computers by exploiting CVE-2013-2465, a critical Java vulnerability that Oracle patched in June. The security bug is present on Java 7 u21 and earlier. Once the bot has infected a computer, it copies itself to the autostart directory of its respective platform to ensure it runs whenever the machine is turned on.

 

Compromised computers then report to an Internet relay chat channel that acts as a command and control server.

Apple's own Macs bitten by Java-based malware attack

Apple's own Macs bitten by Java-based malware attack | 21st Century Learning and Teaching | Scoop.it
From nakedsecurity.sophos.com - February 19, 2013 3:52 PM
Apple released a statement today acknowledging that they were victims of the same attackers that Facebook talked about last week. A zero-day Java vulnerability infected Apple Mac developers through...

 

According to Reuters, "Apple Inc. was recently attacked by hackers who infected the Macintosh computers of some employees".

 

More specifically Apple engineers had their Mac OS X laptops infected by the same zero-day Java vulnerability that infected Facebook last month.

 

In a statement Apple made to The Loop an Apple spokesperson said “The malware was employed in an attack against Apple and other companies, and was spread through a website for software developers.

 

Gust MEES's insight:

What should you do as a result of this? If you are a Mac user you should be sure to keep your computer patched. Apple stated they will be releasing a Java malware removal tool this afternoon to respond to this attack.

 

It is also a good idea to run an up to date anti-virus to detect any future attacks and to disable Java in the browser if you don't require it for day to day web surfing.

 

===> To be fair, that advice applies to all computer users whether they prefer Windows, OS X or Linux. Many times staying safe isn't convenient, but it is an investment that pays off in the long run. <===
