# Tested Version: PSOProxy 0.5

#1. Description

#His technique works fine against Windows XP Professional Service Pack 2 and 3 (English).  
#For this exploit I have tried several strategies to increase reliability and performance:  
#Jump to a static 'call esp'  
#Backwards jump to code a known distance from the stack pointer.  
#The server did not properly handle request with large amounts of data to web server.  
#The following request sends a large amount of data to the web server to process, the server will crash as soon as it is received and processed, causing denial of service conditions.  
#Successful exploitation of these issues allows remote attackers to crash the affected server, denying service to legitimate users.

First 6 pipes are created by its parent processand last 2 by the child process. The pipes names are randomly generated each time it is run all except for one JFNfVUYDXmlZQV.Therefore, we can detect Carbanak by that one pipe, as the "JFNfVUYDXmlZQVI" pipe is always created regardless of other randomly named pipes.Listing Carbanaks named pipes they get grouped as they are created at same time with 2 of them listed prior to the JFNfVUYDXmlZQVI pipe.Carbanak creates a directory named "Mozilla" under ProgramData with hidden files, one of which is AlhEXlUJ.exe used by the service it creates which runs as SYSTEM. The malwares service names created seem to use an already existing service name and add "Sys" at the end of its name.Exploitation steps, output all named pipes and look for "JFNfVUYDXmlZQVI" if detected, exploit the DACL on 2 previously listed pipes and 5 pipes listed after.Successfully tested in VM environment.Carbanak IPC Named Pipes:\\.\Pipe\cltjLnYRKKjUESTvgGdmERTb   RW Everyone\\.\Pipe\tGYNSgZvVXwumEhdcF    RW Everyone\\.\Pipe\JFNfVUYDXmlZQVI   <=====  ALWAYS CREATED  RW Everyone\\.\Pipe\PoUXbOHFRuUZAufnlpMZoqdtIfOX  RW Everyone\\.\Pipe\oBcVHguxbnjGbSgkJptifqvNFgD  RW Everyone\\.\Pipe\iDToHxpSCbEIEHPBeQ  RW Everyone\\.\Pipe\YutsGUYwwUusszByeuXUQK  RW Everyone\\.\Pipe\UfnQmAUTVtEkYvMoUWAZekAuWZHe  RW EveryoneExploit/PoC:#include "windows.h"#include "stdio.h"#include "accctrl.h"#include "aclapi.h"/*Carbanak: 48d208b87b29d50bb160f336c94b681e232b0f90e8c02175e593d60737369c13DACL IPC named pipes created and grants RW access for Everyone.We can identify Carbanak as out of the eight pipes it creates with random names the pipenamed JFNfVUYDXmlZQVI is always created.
