Trojan:Win32/Qakbot.AR!Cert Summary

These modifications can be as follows:

• Executable code extraction. Cybercriminals often use binary packers to hinder the malicious code from reverse-engineered by malware analysts. A packer is a tool that compresses, encrypts, and modifies a malicious file’s format. Sometimes packers can be used for legitimate ends, for example, to protect a program against cracking or copying.
• Injection (inter-process);
• Injection (Process Hollowing);
• Presents an Authenticode digital signature;
• Creates RWX memory. There is a security trick with memory regions that allows an attacker to fill a buffer with a shellcode and then execute it. Filling a buffer with shellcode isn’t a big deal, it’s just data. The problem arises when the attacker is able to control the instruction pointer (EIP), usually by corrupting a function’s stack frame using a stack-based buffer overflow, and then changing the flow of execution by assigning this pointer to the address of the shellcode.
• Possible date expiration check, exits too soon after checking local time;
• A process attempted to delay the analysis task.;
• A named pipe was used for inter-process communication;
• Repeatedly searches for a not-found process, may want to run with startbrowser=1 option;
• A process created a hidden window;
• Unconventionial language used in binary resources: Hungarian;
• Uses Windows utilities for basic functionality;
• Executed a process and injected code into it, probably while unpacking;
