In the majority of the cases, Win32/GenCBL.CI infection will advise its sufferers to initiate funds transfer for the purpose of neutralizing the modifications that the Trojan infection has actually introduced to the sufferer’s device.

Win32/GenCBL.CI Summary

These modifications 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);
  • 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.
  • Possible date expiration check, exits too soon after checking local time;
  • A named pipe was used for inter-process communication;
  • 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.
  • 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
  • Creates a copy of itself;
  • Anomalous binary characteristics. This is a way of hiding virus’ code from antiviruses and virus’ analysts.
  • Ciphering the records found on the victim’s disk drive — so the target can no longer use the information;
  • Preventing routine accessibility 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.

Win32/GenCBL.CI

The most regular networks whereby Win32/GenCBL.CI Ransomware Trojans are injected are:

  • By methods of phishing e-mails.

  • As a consequence of customer ending up on a resource that holds a destructive software program;

As soon as the Trojan is effectively infused, it will certainly either cipher the data on the target’s computer or prevent the tool from functioning in a correct manner – while also placing a ransom note that states the requirement for the victims to effect the payment for the purpose of decrypting the documents or bring back the file system back to the first condition. In most instances, the ransom note will turn up when the client reboots the PC after the system has actually already been damaged.

Nonetheless, the ransom notes as well as techniques of extorting the ransom quantity may vary relying on certain local (regional) settings. The ransom money notes as well as methods of obtaining the ransom money amount might differ depending on specific regional (regional) setups.

For instance:

    In specific areas, the Trojans frequently wrongfully report having actually identified some unlicensed applications made it possible for on the sufferer’s device. The sharp after that demands the user to pay the ransom.

    Faulty declarations about unlawful content.
