How to check if your details have been compromised

Rumour has it that is started with the game World of Warcraft (WoW), where a map designer, intending to write "the player has been owned", mistyped it as "the player has been pwned". In any case, it is widely used today to mean you have been screwed in some way. So there I was, perusing the web, and I found this rather interesting piece on Brian Krebs' blog called Are you on the Pnwedlist? , a piece which introduces a new service from DVLabs (part of Tipping Point) called PwnedList.

PwnedList introduces itself as "...a tool that allows an average person to check if their accounts have been compromised. Now this will sound like great news to a lot of people. And no doubt that it could be useful if you needed proof that your identity has been compromised and wanted to "prove" the case to your bank or other businesses you interact with. This is not the first site to offer this service. Do you use the same password on several sites? Using Debian/Hardened SELinux — Debian SELinux Handbook v0.1.

While the digital paparazzi were lined up waiting to snap photos of the Lulzboat crew getting vanned, some of us focused on how this collection of low tech script kiddies were able to knock over SONY, AT&T, the CIA, Arizona's DPS and numerous other sites and make off with highly confidential contents again and again.

Google is Your Friend - If You're a Lulzer

It turns out that they had an accomplice, Google. Now before the good townspeople grab their torches and pitchforks and beat a hasty path to Mountain View, let it be known that Google's part in these massive hacks isn't actually Google's fault. Or perhaps it can be if the public still wants to blame them anyway and question why this information is there on Google for the taking in the first place. But that's not really the issue at all. The blame in my opinion lies once again with the administrators of the sites which were attacked. After all, page crawls weren't considered privileged information - they're all part of the "public internet" available to anyone who drops by.

A Tcpdump Tutorial and Primer. Image from tcpdump is the premier network analysis tool for information security professionals. Having a solid grasp of this über-powerful application is mandatory for anyone desiring a thorough understanding of TCP/IP. Many prefer to use higher level analysis tools such as Ethereal Wireshark, but I believe this to usually be a mistake. In a discipline so dependent on a true understanding of concepts vs. rote learning, it's important to stay fluent in the underlying mechanics of the TCP/IP suite. A thorough grasp of these protocols allows one to troubleshoot at a level far beyond the average analyst, but mastery of the protocols is only possible through continued exposure to them.

When using a tool that displays network traffic a more natural (raw) way the burden of analysis is placed directly on the human rather than the application.
