Most of the cases, Backdoor.Win32.Bladabindi ransomware will certainly instruct its victims to launch funds transfer for the function of counteracting the changes that the Trojan infection has presented to the sufferer’s tool.

Backdoor.Win32.Bladabindi Summary

These modifications can be as complies with:

  • 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.
  • 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.

    Everything you run, type, or click on your computer goes through the memory. This includes passwords, bank account numbers, emails, and other confidential information. With this vulnerability, there is the potential for a malicious program to read that data.

  • The executable is compressed using UPX;
  • Executed a very long command line or script command which may be indicative of chained commands or obfuscation;
  • A scripting utility was executed;
  • Uses Windows utilities for basic functionality;
  • Executed a process and injected code into it, probably while unpacking;
  • 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
  • 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 records found on the victim’s hard disk drive — so the victim can no longer make use of the information;
  • Preventing normal accessibility to the sufferer’s workstation. This is the typical behavior of a virus called locker. It blocks access to the computer until the victim pays the ransom.
