Malicious computer code that leverages a newly-patched security flaw in Oracle’s Java software is set to be deployed later this week to cybercriminal operations powered by the BlackHole exploit pack.

Blocking JavaScript in the Browser

May 25, 2011

Most Web sites use JavaScript, a powerful scripting language that helps make sites interactive. Unfortunately, a huge percentage of Web-based attacks use JavaScript tricks to foist malicious software and exploits onto site visitors. To protect yourself, it is critically important to have an easy method of selecting which sites should be allowed to run JavaScript in the browser.

Why Counting Flaws is Flawed

November 18, 2010

Once or twice each year, some security company trots out a “study” that counts the number of vulnerabilities that were found and fixed in widely used software products over a given period and then pronounces the most profligate offenders in a Top 10 that is supposed to tell us something useful about the relative security of these programs. And nearly without fail, the security press parrots this information as if it were newsworthy.
