NtQueryObject This function retrieves a lot of useful information about system objects. Because the official MSDN website doesn't describe it very well, I advise you get familiar with the undocumented properties of this function. If the ObjectA llTypesInformation parameter (value 0x03) is used, this runtime returns the detailed information about all objects in the system. When the process is debugged, the DebugObject instances are created. Using the NtQueryObject function one can check how many DebugObject objects exist in the system.

Listing 13 shows the function, that checks debug register values. Methods using the process environment and management These methods are based on system mechanisms used to control the process environment. Thanks to these methods, debuggers can also be detected. Parent Process This method uses the PID (process identifier) of the parent process. exe. If the program was run by the debugger, the debugger will be the parent process of the program. Listing 14 shows the function, Listing 11. = NULL) { *(unsigned char*)pAllocation = 0xC3; // Set the RET opcode if (VirtualProtect(pAllocation, 1,PAGE_EXECUTE_READWRITE | PAGE_GUARD, &OldProtect) == 0) { cout << "Can't set an appropriate flag\n" << endl; } else { __try { __asm { mov eax, pAllocation // Writing memory address to eax register push MemBreakDbg // Pushing MemBreakDbg on the stack jmp eax // Execution code from address stored in eax // If this instruction is executed, function RET will return to the address // placed on the stack – here labeled as MemBreakDbg } } __except(EXCEPTION_EXECUTE_HANDLER) { cout << " – Debugger was not found\n"; __asm {jmp MemBreakEnd} } __asm{MemBreakDbg:} cout << " – Debugger was found\n"; __asm{MemBreakEnd:} VirtualFree(pAllocation, NULL, MEM_RELEASE); } } else { cout <<"Can't allocate memory\n" << endl; } 48 HAKIN9 1/2010 DETECTING DEBUGGERS that checks the parent process.

The malware author is the only party that knows the needed private decryption key. txt file, which users are supposed to use to request for their files to be released after paying a ransom of $100-200 (see Figure 16). Some files are coded. MayArchive began utilizing more sophisticated RSA encryptions, with ever-increasing keys (eg. RSA-4096) which makes it large enough to be computationally infeasible to crack them. One of the example ReadMe File created by these Malware after it has successfully encrypted the users files, is shown below.
