Win32:RansomShade-B [Trj] Summary

These alterations can be as adheres to:

  • 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.

  • Executed a process and injected code into it, probably while unpacking;
  • Detects VirtualBox through the presence of a library;
  • Detects Sandboxie through the presence of a library;
  • Detects SunBelt Sandbox through the presence of a library;
  • Detects the presence of Wine emulator via function name;
  • Deletes its original binary from disk;
  • Checks for the presence of known windows from debuggers and forensic tools;
  • A process attempted to delay the analysis task by a long amount of time.;
  • Creates or sets a registry key to a long series of bytes, possibly to store a binary or malware config;

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

  • Detects Virtual PC through the presence of a registry key;
  • Attempts to modify proxy settings. This trick used for inject malware into connection between browser and server;
  • Attempts to modify browser security settings;
  • Creates a copy of itself;
  • Collects information to fingerprint the system. There are behavioral human characteristics that can be used to digitally identify a person to grant access to systems, devices, or data. Unlike passwords and verification codes, fingerprints are fundamental parts of user’s identities. Among the threats blocked on biometric data processing and storage systems is spyware, the malware used in phishing attacks (mostly spyware downloaders and droppers), ransomware, and Banking Trojans as posing the greatest danger.
