The China-linked Advanced Persistent Threat (APT) group known as Salt Typhoon has waged an expansive espionage campaign against global networks, infiltrating over 600 organizations across 80 countries, including around 200 in the U.S.
Key Impact & Tactics:
- Targeted Sectors: Telecommunications, government, transportation, lodging, and military infrastructure have all been compromised.
- Initial Access via Known Vulnerabilities: Salt Typhoon exploited longstanding issues in widely used network edge devices:
- Persistent Network Access: By modifying ACLs, opening non-standard ports, establishing GRE/IPsec tunnels, and abusing containerized tools like Cisco’s Guest Shell, the attackers ensured continued access and evaded detection.
- Lateral Movement & Exfiltration: They captured authentication traffic (e.g., RADIUS, TACACS+), altered routing configurations, deleted logs, and leveraged peering links and tunnels for data exfiltration.
- Global Coordination of Response: Security agencies from 13 countries, including the U.S., U.K., Canada, and others, issued a joint advisory urging threat hunting, patching, and mitigation to prevent further compromise.
Conclusion
Salt Typhoon demonstrates how sophisticated threat actors can exploit known vulnerabilities to destabilize critical infrastructure and compromise data privacy at an alarming scale. This campaign underscores the importance of proactive defense, cross-border cooperation, and comprehensive device hardening.
