Malware.AI.1677857945 Summary

These modifications 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.
  • Presents an Authenticode digital signature;
  • 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: Russian;

  • Sniffs keystrokes;

    • 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.
  • Anomalous binary characteristics. This is a way of hiding virus’ code from antiviruses and virus’ analysts.
  • Ciphering the records located on the sufferer’s hard drive — so the sufferer can no more utilize the data;

  • As a consequence of individual winding up on a resource that organizes a harmful software program;

As soon as the Trojan is effectively infused, it will certainly either cipher the information on the sufferer’s computer or prevent the gadget from operating in a correct way – while also putting a ransom note that points out the requirement for the targets to effect the repayment for the function of decrypting the papers or restoring the documents system back to the initial condition.
