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.
  • Looks up the external IP address;
  • Uses Windows utilities for basic functionality;
  • Unusual version info supplied for binary;
  • Uses suspicious command line tools or Windows utilities;
  • Ciphering the documents situated on the sufferer’s hard disk drive — so the sufferer can no longer make use of the information;
  • Preventing regular access 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.
