Introduction: A recent cyber campaign, identified by Security Scorecard as involving China’s “Typhoon” crews, has compromised over 1,000 devices—mainly in the U.S. and East Asia. This stealthy operation aims to establish networks for long-term access to critical infrastructure using a fake LAPD certificate to disguise its activities.
Key Details:
- Who: Security Scorecard’s threat intelligence team.
- What: Ongoing breaches targeting end-of-life routers, IoT devices, and more, creating an Operational Relay Box (ORB) network.
- When: The campaign likely started in September 2023.
- Where: Predominantly affecting the U.S. (352 victims) and regions like Japan, South Korea, Taiwan, and Hong Kong.
- Why: To facilitate covert cyberattacks by obscuring the attackers’ actual network locations.
- How: Attackers exploit vulnerabilities in devices, notably creating a backdoor called ShortLeash that appears to be signed by a legitimate authority, maintaining connectivity for further intrusions.
Why It Matters:
- Enterprise Security: Compromised devices pose significant risks to operational integrity and data security.
- Cloud Compliance: Organizations must enhance compliance measures against sophisticated threats targeting cloud and hybrid environments.
- Automation and Performance: Deployment of automated defenses and monitoring solutions can mitigate risks by identifying anomalous behavior, such as unusual connections from residential IP addresses.
Takeaway: IT professionals should closely monitor their networks for anomalies, particularly from unmonitored devices making unexpected connections, and assess their existing security frameworks to enhance resilience against this stealthy campaign.
