Most of the instances, Trojan:MSIL/Injector.SO!bit infection will advise its targets to start funds move for the function of counteracting the amendments that the Trojan infection has presented to the target’s device.

Trojan:MSIL/Injector.SO!bit Summary

These modifications 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.
  • 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.;
  • 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.
  • The binary likely contains encrypted or compressed data. In this case, encryption is a way of hiding virus’ code from antiviruses and virus’ analysts.
  • Attempts to remove evidence of file being downloaded from the Internet;
  • Sniffs keystrokes;
  • A process was set to shut the system down when terminated;
  • 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.
  • Creates a copy of itself;
  • Ciphering the documents situated on the target’s disk drive — so the sufferer can no more make use of the information;
  • Preventing routine accessibility 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.

The most normal networks whereby Trojan:MSIL/Injector.SO!bit Ransomware Trojans are infused are:

  • By methods of phishing e-mails. Email phishing is a cyber attack that uses disguised email as a goal is to trick the recipient into believing that the message is something they want or need — a request from their bank, for instance, or a note from someone in their company — and to click a link for download a malware.
  • As a repercussion of user ending up on a source that organizes a destructive software application;

As quickly as the Trojan is effectively infused, it will certainly either cipher the data on the sufferer’s PC or prevent the device from operating in a proper fashion – while also positioning a ransom money note that points out the requirement for the victims to effect the payment for the purpose of decrypting the records or bring back the data system back to the preliminary problem. In many instances, the ransom money note will certainly turn up when the customer restarts the PC after the system has currently been damaged.

Trojan:MSIL/Injector.SO!bit circulation networks.

In different corners of the world, Trojan:MSIL/Injector.SO!bit expands by jumps and bounds. However, the ransom notes and also tricks of obtaining the ransom money amount may differ depending upon specific local (regional) settings.
