What is Adult Traffic Trading.

This short video blog explains what “Adult Traffic Trading” is. This series of Video Blogs is in response to a study done about adult content web sites. This is a really, really short video, but the answer is simple enough to answer the question that it doesn’t need to be a long video. Randy Abrams

Getting a Kindle for Xmas?

This isn’t exactly a security post, although when things go wrong on electronic devices viruses almost always are suspected and blamed. Well, the truth is that sometimes it is a hardware problem. Many Kindle users complained of crashes. The Kindle has not been found to have exploitable vulnerabilities (yet) and isn’t even reported to have

A Primer on Drive-by Downloads

Here in the Cyber Threat Analysis Center we’re starting to add video blogs.

Premium Phish

Opt Out isn’t Just for One Day

WWW – Web Weaponization and WikiLeaks

Unless you’ve been on a sabbatical in a remote and unconnected part of the world, I don’t think you could have missed the news regarding WikiLeaks (the “whistleblower” web site) and its founder, Julian Assange. To put it succinctly, in the last few weeks, attempts have been made to shut down WikiLeaks’ operations- from payment
