• 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.

  • HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
  • HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce
• Checks the CPU name from registry, possibly for anti-virtualization;
• Attempts to modify proxy settings. This trick used for inject malware into connection between browser and server;
• Anomalous binary characteristics. This is a way of hiding virus’ code from antiviruses and virus’ analysts.
• Ciphering the documents located on the target’s hard disk drive — so the sufferer can no more use the data;
• Preventing regular access to the victim’s workstation. This is the typical behavior of a virus called locker. It blocks access to the computer until the victim pays the ransom.
