Exploits (36)

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. (This doesn't mean pvefindaddr is now entirely worthless, because not all functions have been ported into mona yet, but we won't be releasing any updates to pvefindaddr anymore and the entire project page/download page will eventually disappear) Read more

I think we all agree that bypassing DEP (and ASLR) is no longer a luxury today. As operating systems (such as Windows 7) continue to gain popularity, exploit developers are forced to deal with increasingly more memory protection Read more

Interested in capturing, documenting and analyzing scans and malicious activity, Corelan Team decided to set up a honeypot and put it online. In the first week of december 2010, Obzy built a machine (default Windows XP SP3 installation, no patches, firewall turned off), named it "EGYPTS-AIRWAYS", set up a honeypot + some other monitoring tools, and connected it to the internet.

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

About a month after releasing an ftp client fuzzer module for Metasploit, I decided to release yet another fuzzer module I have been working on over the last few weeks.

This new module can be used to audit Read more

Over the past few weeks, Corelan Team has given its undivided attention to fuzzing ftp client applications. Using a custom built ftp client fuzzer, now part of the Metasploit framework, the team has audited several ftp clients and applications that use an embedded client ftp component. One example of such an application is a tool that would synchronize / backup data from a computer to a remote ftp server. The 3 main audit/attack vectors that were used during the "project" were send back overly long responses to ftp commands / requests sent by the ftp client to the server send back a file/directory listing that contains overly long file/folder names try to download a file that has an overly long filename.

This page hosts an unofficial list of applications that are said to be vulnerable to the dll hijacking flaw (or feature or whatever you want to call it). Note that I did not test these applications myself.
