What is blkfqnikz.php and Its Purpose?

The blkfqnikz.php file is a backdoor script designed to grant attackers unrestricted access to compromised websites. It typically infiltrates through vulnerabilities in plugins, themes, or outdated WordPress installations. Its purposes include:

  3. Stealthy operations: Hackers often obfuscate the script or hide it in legitimate directories, making detection challenging for security tools.
  4. Persistent control: After installation, the script helps hackers maintain access to the site, even when other vulnerabilities are resolved.
  5. Resource exploitation: Attackers may use your server for illegal activities like cryptocurrency mining or launching further attacks.

The presence of blkfqnikz.php compromises your website’s integrity, security, and reputation.
