How Does Wacatac.B!ml Works

This malware actively makes the following modifications:

  • Cybercriminals frequently employ binary packers to actively prevent malware analysts from reverse-engineering malicious code.
  • It generates RWX memory, a memory-based security trick that allows an attacker to fill a buffer with a shellcode and then execute it.
  • This becomes challenging when an attacker can change the order of execution by assigning the instruction pointer (EIP) to the address of the shellcode.
  • The binary is likely to contain encrypted or compressed data, which conceals virus code from antiviruses and virus experts.
  • API logs identify network activity but do not express it openly. Microsoft built an API solution into its Windows OS that displays network activity for all programs and apps. This malware, on the other hand, conceals network activities.
  • The virus adds several new entries to the HOSTS file and modifies several registry keys.

People can safeguard their systems against this malicious Trojan by taking the appropriate safety measures.

To protect against malware threats, one must use reliable antivirus software, keep systems updated, and adopt safe computing practices.
