Exploits (39)

Ho Ho Ho friends,

It has been a while since we posted something on the Corelan Team blog, I guess we all have been busy doing ... stuff and things, here and there.  Nevertheless, as the year is close Read more

On June 14, 2011 HD Moore announced the Metasploit Bounty contest, offering a cash incentive for specific vulnerabilities to be submitted as modules in the Metasploit Framework. Titled "30 exploits, $5000 in 5 weeks", a post on the Rapid7 blog lists the 30 "bounties" selected by the MSF team, waiting for someone to claim and submit a working exploit module. Read more

Over the last few weeks, there has been some commotion about a universal DEP/ASLR bypass routine using ROP gadgets from msvcr71.dll (written by Immunity Inc) and the fact that it might have been copied into an exploit submitted to Metasploit as part of the Metasploit bounty.

FINALLY ! After spending almost 6 months of designing, developing and testing, and after 'surviving' 2 presentations (at AthCon and Hack In Paris), I am extremely excited and proud to present, on behalf of the entire Corelan Team, the general availability of mona.py. With this announcement, we also declare pvefindaddr officially dead from this point forward.

Yesterday, sickn3ss (one of the frequent visitors of the #corelan channel on freenode IRC) posted a really interesting question.

While testing ROP gadgets, as part of the process of building a DEP bypass exploit for WM Downloader, Read more

This morning, my generic attachment filter for MS Exchange reported that about 100 emails were put in quarantine because they contained a small zip file. When looking inside the zip file, I found a small pdf file… I immediately figured this file was up to no good, so it was time to get my hands dirty :) Read more
