InnoSetup Execute Shellcode PoC
This proof of concept demonstrate how to take advantage of InnoSetup Scripting Engine to host local/remote process shellcode payload then execute.
The idea behind this concept is to demonstrate the dangerosity of (self) installers. Not only they can contain malicious programsn, they can also run native code through their scripting engines and evade AV detections because of their natural aspect.
The most difficult part was to understand how to use pointers/refs. Basically from this example, it is possible to create any kind of Malware from scratch (even more complex ones). Feel free to try, if you have any technical questions, feel free to ask for some help.Read more...
Microsoft Windows suffer from a serious lack of protection in their authentication mechanism which could led in privilege escalation.
Indeed, in default installation of Windows (all version), the account lockdown policy is disabled plus authentication API's doesn't limit number of attempts per seconds which could led to a medium to fast brute-force attacks.
Using our PoC and depending of the number of cores available in the target system you could test from few thousands to dozen of thousands of password per second.
Considering that those kind of authentication API's could be used by any Windows account, even a Guest user could use the PoC to recover / crack the password of any local user and escalate his privilege.Read more...
