- The stage where an attacker establishes a communication channel with a compromised system
- Send commands to the infected machine
- Receive exfiltrated data
- Maintain persistent remote access
- Attackers disguise communication as normal traffic
- Using platforms like:
- Why this works:
- Traffic appears legitimate
- Blends into normal user behavior
- Harder for detection systems to flag
- The phase where the attacker achieves their intended objective
- Sensitive data such as:
- Financial records
- Credit card data
- Credentials
- Intellectual property
- Operate stealthily
- Maintain long-term access
- Avoid detection while extracting value
- A layered security strategy designed to protect systems at multiple levels
- Cyber Defense Matrix
- Identify malicious or suspicious activity
- Prevent unauthorized access
- Interrupt attacker operations
- Reduce the effectiveness of the attack
- Mislead attackers (e.g., honeypots, fake assets)
- Limit the spread and impact of an attack
- No single security control is sufficient
- Attacks occur in multiple stages
- Cover every phase of the Cyber Kill Chain
- C2 enables attackers to remotely control compromised systems
- Attackers often hide communication within legitimate traffic
- Actions on Objectives is where real damage or data theft occurs
- Defense in Depth provides layered protection across all stages
- Security should be proactive, not reactive
- C2 → Control the system
- Actions → Achieve the objective
- Defense → Detect, limit, and stop the attack
