Beaconing
A method used by malware to communicate with an attacker-controlled server for command execution.
Understanding Beaconing
Beaconing is commonly associated with advanced persistent threats (APTs) and botnets. Malware deployed on a compromised system silently sends signals at scheduled intervals, allowing attackers to track infections and issue further instructions.
Common Attack Techniques
Stealth C2 Communication: Malware sends encrypted or disguised signals to avoid detection.
Data Exfiltration: Gradual transmission of stolen data to an attacker-controlled server.
Network Reconnaissance: Gathering information about the victim’s system and network.
Best Practices
Monitor network traffic for unusual outbound connections.
Implement Endpoint Detection and Response (EDR) solutions.
Use threat intelligence to identify malicious domains and IPs.
Employ behavior-based detection to flag suspicious communication patterns.
