Trojan:Win32/Cryptinject.PVA!MTB Summary

These alterations can be as adheres to:

  • 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);
  • Attempts to connect to a dead IP:Port (4 unique times);
  • 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.
  • Performs some HTTP requests;
  • The binary likely contains encrypted or compressed data. In this case, encryption is a way of hiding virus’ code from antiviruses and virus’ analysts.
  • Attempts to remove evidence of file being downloaded from the Internet;
  • Executed a process and injected code into it, probably while unpacking;

    • HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
    • HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce

  • Creates a copy of itself;
  • Anomalous binary characteristics. This is a way of hiding virus’ code from antiviruses and virus’ analysts.
  • Ciphering the papers found on the sufferer’s hard disk drive — so the victim can no more make use of the data;
  • Preventing normal accessibility to the sufferer’s workstation. This is the typical behavior of a virus called locker. It blocks access to the computer until the victim pays the ransom.
