Win32/Kryptik.HIWN 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.
  • 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;
  • Expresses interest in specific running processes;

  • Ciphering the records found on the target’s hard disk drive — so the target can no more use the data;
  • 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.

As soon as the Trojan is effectively infused, it will certainly either cipher the data on the target’s computer or stop the tool from functioning in a correct fashion – while likewise placing a ransom note that mentions the need for the targets to effect the repayment for the purpose of decrypting the documents or recovering the file system back to the preliminary problem. In a lot of circumstances, the ransom note will turn up when the customer restarts the COMPUTER after the system has already been harmed.
