What problem does it solve?
Malware often uses covert channels to hide C2 and data exfiltration in network traffic. This skill helps security teams detect and analyze DNS tunneling, ICMP exfiltration, HTTP covert channels, and protocol abuse in PCAP captures and network logs.
Core Features & Use Cases
- Detect and analyze DNS covert channels including high-entropy subdomains, long query names, and unexpected query volumes.
- Identify ICMP covert channels and data exfiltration through payload size, entropy, and flow-based analysis.
- Discover HTTP header covert data leakage via oversized cookies and custom headers with anomalous entropy.
- Flag protocol abuse and unusual IP protocol usage to uncover nonstandard channel methods.
- Use Case: during incident response or threat hunting, analyze a PCAP to surface hidden C2 beacons and exfiltration events and generate actionable findings.
Quick Start
Import a PCAP file into your analysis workspace and run the detection agent to generate a covert-channel analysis report.
