Internet Relay Chat (IRC): 194

Security Weaknesses

  • Unencrypted communication, making it vulnerable to eavesdropping.

  • Abuse for botnet command and control (C2) communications.

  • Exploitation of weak authentication.

Security Defense and Mitigation Measures

  • Use secure IRC with SSL/TLS encryption.

  • Monitor and block IRC traffic if not required.

  • Implement strong authentication measures for IRC servers.

Indicators of Compromise or Attack

  • Unusual outgoing connections to IRC servers.

  • High volumes of IRC traffic.

  • Known botnet C2 IPs or domains in network logs.
