MSIL/Kryptik.QDX 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);
  • Injection with CreateRemoteThread in a remote process;
  • 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.
  • 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.

  • 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.
  • Sniffs keystrokes;
  • Executed a process and injected code into it, probably while unpacking;
  • Code injection with CreateRemoteThread in a remote process;
  • 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.
  • Likely virus infection of existing system binary;
  • Creates known SpyNet mutexes and/or registry changes.;
  • Ciphering the papers situated on the target’s disk drive — so the victim can no longer make use of the information;
  • 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.

MSIL/Kryptik.QDX

The most normal channels whereby MSIL/Kryptik.QDX are injected are:

  • By methods of phishing e-mails.

  • As a repercussion of individual ending up on a resource that organizes a destructive software;

As soon as the Trojan is successfully injected, it will certainly either cipher the data on the victim’s computer or stop the gadget from operating in an appropriate fashion – while likewise placing a ransom money note that points out the requirement for the sufferers to impact the payment for the objective of decrypting the files or restoring the file system back to the initial problem. In most circumstances, the ransom money note will come up when the customer restarts the PC after the system has currently been damaged.

MSIL/Kryptik.QDX circulation networks.

However, the ransom money notes as well as techniques of extorting the ransom money quantity may vary depending on certain neighborhood (local) settings. The ransom notes and tricks of extorting the ransom quantity may differ depending on specific regional (regional) settings.
