I was analyzing a piece of malware the other day and came across a unique method to place malware locally on a host without using the network to transfer it. This is something that is so simple in design, and yet so effective in its delivery. Let’s take a closer look. To get the malicious Read more…
We all know the dangers of peer-to-peer (P2P) networks and their role in distributing malware. Most people who deal with this problem work tirelessly to limit the impact of these potential threat points by (among other things) adding anti-virus, firewalling, watching network flows for P2P traffic, and usually outright banning of P2P applications.

Just in case you have been lucky enough not to have dealt with this malware, it goes roughly like this: You get an email from what looks to be a legitimate source, or visit a legitimate looking website that is offering the Read more…
The latest Microsoft ActiveX flaw disclosure looks like a silently patched issue. The flaw, disclosed by US-CERT, was not part of Microsoft’s MS07-069 Security Bulletin released in December of 2007. The CVE ID (CVE-2007-6255) is not listed in Microsoft’s Bulletin at the time of this writing and is still in the reserved state on MITRE’s Read more…
A Microsoft Works ActiveX potential zero-day threat has been disclosed on a handful of Chinese blog sites. This threat was originally posted as a proof of concept that caused a Windows host to crash, but very soon after, a working exploit was posted. (Show of hands: Who’s surprised?) Here’s the meat of this: The flaw Read more…
A vulnerability has popped up (no pun intended…really) in Internet Explorer (IE) — or at least is claimed by a researcher named Juan Pablo Lopez Yacubian on the popular Bugtraq mailing list. It allows one to spoof the address of a popup without affecting the underlying page. This means that a bad guy could send Read more…
