  • Injection (Process Hollowing);
  • 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;
  • Reads data out of its own binary image. The trick that allows the malware to read data out of your computer’s memory.

    • HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
    • HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce
  • Network activity detected but not expressed in API logs. Microsoft built an API solution right into its Windows operating system it reveals network activity for all apps and programs that ran on the computer in the past 30-days. This malware hides network activity.
  • Creates a copy of itself;
  • Ciphering the documents found on the sufferer’s disk drive — so the victim can no more make use of the data;
  • Preventing routine accessibility to the target’s workstation. This is the typical behavior of a virus called locker. It blocks access to the computer until the victim pays the ransom.
