Ransom.VenusLocker.4 (B) Summary

These modifications can be as complies with:

  • Injection (inter-process);
  • Injection (Process Hollowing);
  • Attempts to connect to a dead IP:Port (3 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.
  • At least one IP Address, Domain, or File Name was found in a crypto call;
  • Repeatedly searches for a not-found process, may want to run with startbrowser=1 option;
  • A process created a hidden window;
  • Drops a binary and executes it. Trojan-Downloader installs itself to the system and waits until an Internet connection becomes available to connect to a remote server or website in order to download additional malware onto the infected computer.
  • Performs some HTTP requests;
  • Uses Windows utilities for basic functionality;
  • Executed a process and injected code into it, probably while unpacking;
  • Queries information on disks, possibly for anti-virtualization. Since VMs share the same disk space so it is expected that they won’t be getting as much space as an application running on
    native hardware will have access to.
  • 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;
  • Attempts to remove evidence of file being downloaded from the Internet;
  • Deletes its original binary from disk;
  • Installs itself for autorun at Windows startup. There is simple tactic using the Windows startup folder located at:
    C:\Users\[user-name]\AppData\Roaming\Microsoft\Windows\StartMenu\Programs\Startup. Shortcut links (.lnk extension) placed in this folder will cause Windows to launch the application each time [user-name] logs into Windows.

    The registry run keys perform the same action, and can be located in different locations:

    • HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
    • HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
    • HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
    • HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce
  • Creates a hidden or system file. The malware adds the hidden attribute to every file and folder on your system, so it appears as if everything has been deleted from your hard drive.
  • Operates on local firewall’s policies and settings;
  • Creates a copy of itself;
  • Attempts to disable Windows Defender;
  • Attempts to create or modify system certificates;
  • Anomalous binary characteristics. This is a way of hiding virus’ code from antiviruses and virus’ analysts.
  • Ciphering the documents situated on the sufferer’s hard disk — so the sufferer can no longer use the data;
  • Preventing regular access 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.
