In the majority of the cases, Mal/Agent-AVK virus will instruct its sufferers to start funds transfer for the function of neutralizing the modifications that the Trojan infection has introduced to the target’s device.

Mal/Agent-AVK Summary

These alterations 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 papers found on the victim’s hard disk — so the victim can no more use the data;
  • Preventing normal access 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.

  • As a consequence of customer winding up on a source that organizes a destructive software application;

As quickly as the Trojan is successfully infused, it will either cipher the data on the target’s PC or stop the gadget from operating in a correct manner – while also placing a ransom note that points out the requirement for the victims to impact the repayment for the purpose of decrypting the papers or bring back the documents system back to the first problem. In the majority of circumstances, the ransom money note will show up when the client reboots the PC after the system has currently been harmed.

Mal/Agent-AVK distribution networks.

In numerous edges of the globe, Mal/Agent-AVK expands by jumps and bounds. Nevertheless, the ransom notes and methods of obtaining the ransom amount might vary depending upon particular regional (regional) settings. The ransom notes as well as tricks of extorting the ransom quantity may vary depending on specific regional (regional) setups.
