Trojan:Win32/SmokeLoader.YL Summary

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);
  • 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.
  • A process attempted to delay the analysis task.;
  • Attempts to connect to a dead IP:Port (13 unique times);
  • Starts servers listening on;
  • 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
  • A possible cryptomining command was executed;
  • Attempts to interact with an Alternate Data Stream (ADS);
  • Anomalous binary characteristics. This is a way of hiding virus’ code from antiviruses and virus’ analysts.
  • Ciphering the records found on the victim’s hard disk — so the target can no more utilize the information;
  • 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.
