These adjustments can be as follows:

  • 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 (2 unique times);
  • Presents an Authenticode digital signature;
  • 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.

  • Executed a process and injected code into it, probably while unpacking;
  • Attempts to repeatedly call a single API many times in order to delay analysis time. This significantly complicates the work of the virus analyzer. Typical malware tactics!
  • A system process is generating network traffic likely as a result of process injection;
  • Installs itself for autorun at Windows startup.

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