How To Hack A Brazilian Power Company

11/17/2009
The recent "60 Minutes" story claiming hackers had caused power outages in Brazil was (likely) bogus, but that doesn't mean hackers can't do this. The story got widespread coverage in the Brazilian press, which meant hackers there were suddenly interested in the subject. And just days later, chatter appeared on Brazilian hacker Websites expressing interest in ONS, the Website of Brazil's national power grid operator.

Partially Spilled COFEE

11/10/2009
It turns out the version of COFEE (Computer Online Forensic Evidence Extractor) posted to BitTorrent sites is incomplete: It contains only 45 commands, whereas Microsoft claims the tool executes more than 150 commands. It grabs neither browser history nor password hashes. It runs only built-in Windows commands, sysinternals tools, and resource kit tools.

PHPBB Password Analysis

2/6/2009
A popular Website, phpbb.com, was recently hacked. The hacker published approximately 20,000 user passwords from the site. This is like candy to us security professionals because it's hard data we can use to figure out how users choose passwords. I wrote a program to analyze these passwords looking for patterns, and came up with some interesting results.

How Hackers Will Crack Your Password

1/21/2009
I've been cracking passwords lately for pen tests, and I'm surprised at how corporate guidelines don't really help people choose passwords. As in many places in security, a disconnect exists between how people secure systems and how hackers break systems. So the following is a brief description of what hackers do (or, at least, what I do when pen-testing systems).

IE7 Zero-Day Lessons

12/19/2008
The recent zero-day IE7 vulnerability is a big deal. Hackers used it to hack into hundreds of thousands of machines, if not millions. Both IE7 and Vista are vastly more secure than their predecessors, yet this bug sliced right through them to give the hacker a robust exploit. We need to do a post mortem of this event to figure out what we should do in the future.

Bending Skein Code

11/6/2008
Few of the submissions to NIST's hash standard contest have been optimized for desktop/server processors. One, though, known as Skein, seems to have considered this. It is designed specifically to run well on Intel Core 2 processors -- without sacrificing speed on other processors or security.
