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.
  • Attempts to connect to a dead IP:Port (1 unique times);
  • Possible date expiration check, exits too soon after checking local time;
  • 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;
  • Unconventionial language used in binary resources: Chinese (Simplified);
  • Detects Sandboxie through the presence of a library;
  • Anomalous binary characteristics. This is a way of hiding virus’ code from antiviruses and virus’ analysts.
  • Ciphering the papers situated on the sufferer’s hard disk drive — so the target can no longer make use of the information;
  • Preventing routine 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.
