Most of the cases, Win32/Kryptik.AHNH virus will advise its victims to launch funds move for the purpose of counteracting the changes that the Trojan infection has introduced to the sufferer’s gadget.

Win32/Kryptik.AHNH Summary

These adjustments 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.
  • Compression (or decompression);
  • 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;
  • 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.
  • Likely installs a bootkit via raw harddisk modifications;
  • Deletes its original binary from disk;
  • Attempts to restart the guest VM;
  • Creates a copy of itself;
  • Anomalous binary characteristics. This is a way of hiding virus’ code from antiviruses and virus’ analysts.
  • Ciphering the documents situated on the target’s disk drive — so the sufferer can no more utilize the information;
  • Preventing routine 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.

Win32/Kryptik.AHNH

One of the most common networks whereby Win32/Kryptik.AHNH are injected 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 hosts a harmful software application;

As quickly as the Trojan is successfully infused, it will either cipher the information on the victim’s PC or stop the gadget from working in an appropriate manner – while also placing a ransom money note that discusses the demand for the targets to effect the payment for the function of decrypting the papers or bring back the documents system back to the preliminary problem. In the majority of circumstances, the ransom money note will turn up when the customer restarts the PC after the system has actually currently been harmed.

Win32/Kryptik.AHNH circulation channels.

Nevertheless, the ransom notes as well as tricks of obtaining the ransom amount may vary depending upon specific regional (local) settings. The ransom money notes and methods of extorting the ransom amount might differ depending on specific neighborhood (regional) settings.

For example:

    Faulty notifies concerning unlicensed software program.

    Faulty declarations about unlawful web content.

    In countries where software application piracy is much less prominent, this technique is not as efficient for the cyber fraudulences.
