Exfiltration Over C2 Channel
Adversaries may steal data by exfiltrating it over an existing command and control channel. Stolen data is encoded into the normal communications channel using the same protocol as command and control communications.

Detection logic
Analyze network data for uncommon data flows (e.g., a client sending significantly more data than it receives from a server). Processes utilizing the network that do not normally have network communication or have never been seen before are suspicious. Analyze packet contents to detect communications that do not follow the expected protocol behavior for the port that is being used.

MITRE mitigations
Data Loss Prevention (DLP) involves implementing strategies and technologies to identify, categorize, monitor, and control the movement of sensitive data within an organization. This includes protecting data formats indicative of Personally Identifiable Information (PII), intellectual property, or financial data from unauthorized access, transmission, or exfiltration. DLP solutions integrate with network, endpoint, and cloud platforms to enforce security policies and prevent accidental or malicious data leaks. (Citation: PurpleSec Data Loss Prevention) This mitigation can be implemented through the following measures: Sensitive Data Categorization: - Use Case: Identify and classify data based on sensitivity (e.g., PII, financial data, trade secrets). - Implementation: Use DLP solutions to scan and tag files containing sensitive information using predefined patterns, such as Social Secur…

- AN0988 · Analytic 0988 — Identifies suspicious outbound traffic volume mismatches from processes that typically do not generate network activity, particularly over C2 protocols like HTTPS, DNS, or custom TCP/UDP ports, following file or data access.
- AN0989 · Analytic 0989 — Monitors for processes reading sensitive files then immediately initiating unusual outbound connections or bulk transfer sessions over persistent sockets, particularly with encrypted or binary payloads.
- AN0990 · Analytic 0990 — Detects unauthorized applications or scripts accessing sensitive data followed by establishing encrypted outbound communication to rare external destinations or with abnormal byte ratios.
- AN0991 · Analytic 0991 — Detects VMs sending outbound traffic through non-standard services or to unknown destinations. Exfiltration over reverse shells tunneled via VMkernel or custom payloads routed via hostd/vpxa.
