Trojan-Ransom.Cerber (A) 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.
  • Injection (inter-process);
  • Injection (Process Hollowing);
  • Compression (or decompression);
  • Attempts to connect to a dead IP:Port (4 unique times);
  • 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.

  • Attempts to modify proxy settings. This trick used for inject malware into connection between browser and server;
  • Attempts to access Bitcoin/ALTCoin wallets;
  • Generates some ICMP traffic;
  • 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 files found on the victim’s hard disk drive — so the victim can no longer use the information;
  • Preventing normal access 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.
