Trojan preying on out-of-date Java installations
Aug 22nd
Sunbelt Blog | August 20, 2010
A piece by Marian Radu on Microsoft’s Technet Blog is warning that users who have failed to update the Java Runtime Environment (JRE) on their machines are vulnerable to drive-by downloads by a Trojan called Unruy. That Trojan has been associated with rogue security products. Radu said the vulnerability (which was patched in March) is being actively exploited.
Browsers running JRE versions up to version 6 update 18 are vulnerable. The current JRE version today is version 6, update 21.
Users can easily check their version of Java and download necessary updates here: »www.java.com/en/download/manual.jsp

They operate primarily by using Javascript Code. Javascript is very common and the internet would be a horribly bland place without it, which makes it the perfect vehicle. Javascript are little snippets of code that are included in websites to generate dynamic content, like time stamps and the like. They allow a website to offload some of the heavy lifting and More >
