Win32/Kryptik.GJNK Summary

These modifications 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.
  • 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.
  • Unconventionial language used in binary resources: Slovenian;
  • The binary likely contains encrypted or compressed data. In this case, encryption is a way of hiding virus’ code from antiviruses and virus’ analysts.
  • Collects information to fingerprint the system. There are behavioral human characteristics that can be used to digitally identify a person to grant access to systems, devices, or data. Unlike passwords and verification codes, fingerprints are fundamental parts of user’s identities. Among the threats blocked on biometric data processing and storage systems is spyware, the malware used in phishing attacks (mostly spyware downloaders and droppers), ransomware, and Banking Trojans as posing the greatest danger.
  • Anomalous binary characteristics. This is a way of hiding virus’ code from antiviruses and virus’ analysts.
  • Ciphering the documents situated on the victim’s disk drive — so the victim can no more make use of the information;
  • Preventing regular access 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/Kryptik.GJNK

One of the most typical networks whereby Win32/Kryptik.GJNK 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 customer ending up on a source that holds a malicious software application;

As soon as the Trojan is effectively infused, it will certainly either cipher the data on the sufferer’s PC or prevent the device from functioning in a correct manner – while also putting a ransom money note that points out the requirement for the targets to effect the repayment for the purpose of decrypting the records or recovering the data system back to the preliminary condition. In most instances, the ransom note will come up when the client reboots the PC after the system has actually currently been harmed.

Win32/Kryptik.GJNK distribution channels.

In different corners of the globe, Win32/Kryptik.GJNK grows by jumps and bounds. However, the ransom notes and also techniques of obtaining the ransom money amount might differ relying on certain local (regional) setups. The ransom notes and also techniques of extorting the ransom amount might vary depending on specific neighborhood (regional) settings.

For example:

    Faulty signals about unlicensed software program.

    In particular areas, the Trojans often wrongfully report having detected some unlicensed applications enabled on the sufferer’s gadget. The alert then demands the individual to pay the ransom money.

    Faulty statements about prohibited content.

    In nations where software application piracy is much less prominent, this method is not as efficient for the cyber fraudulences. Alternatively, the Win32/Kryptik.GJNK popup alert might falsely assert to be deriving from a law enforcement institution and will certainly report having located kid pornography or other illegal information on the device.
