Attempted Malvertising on KrebsOnSecurity.com

November 29, 2011

Members of an exclusive underground hacker forum recently sought to plant malware on KrebsOnSecurity.com, by paying to run tainted advertisements through the site’s advertising network — Federated Media. The attack was unsuccessful thanks to a variety of safeguards, but it highlights the challenges that many organizations face in combating the growing scourge of “malvertising.”

Time to Patch Your Flash

April 15, 2011

If it seems like you just updated your Flash Player software to plug a security hole that attackers were using to break into computers, you’re not probably not imagining things: Three weeks ago, Adobe rushed out a new version to sew up a critical new security flaw. Today, Adobe issued a critical Flash update to eliminate another dangerous security hole that criminals are actively exploiting.

This new update addresses a vulnerability first detailed here at KrebsOnSecurity.com on Tuesday, and Adobe deserves credit for responding quickly with a patch. But there are few things that are simple about updating Flash, which ships in a dizzying array of version numbers and for many users must be deployed at least twice to cover all browsers. In addition, users may have to uninstall the existing version before updating to guarantee a trouble-free install. Also, Adobe Air will need to be updated if that software also is already installed. Finally, fixing this same vulnerability in Adobe Reader and Acrobat will require installing another patch, which won’t be out for at least another 10 days.

And nearly without fail, the security press parrots this information as if it were newsworthy.
