Win32:MBRlock-EH [Trj] Summary

These adjustments can be as follows:

  • Injection (inter-process);
  • Injection (Process Hollowing);
  • 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.
  • Unconventionial language used in binary resources: Russian;
  • Executed a process and injected code into it, probably while unpacking;
  • 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 records found on the target’s disk drive — so the target can no more make use of the information;
  • Preventing normal 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.

  • As an effect of individual ending up on a source that holds a harmful software;

As soon as the Trojan is effectively injected, it will either cipher the information on the target’s PC or stop the device from working in an appropriate fashion – while also positioning a ransom money note that mentions the demand for the victims to impact the payment for the purpose of decrypting the papers or recovering the documents system back to the first condition.
