🔥 Active Threat Campaigns
🐉 “Volt Typhoon” – Targeting U.S. and Asia-Pacific Critical Infrastructure
Believed to be a China-linked APT group, Volt Typhoon is focusing on long-term espionage. The group infiltrates government and private sector networks via living-off-the-land techniques and stealthy communications.
Key Tactics:
-
Exploiting vulnerable edge devices
-
Using legitimate credentials
-
Avoiding malware for stealth
Sectors Affected: Telecom, transportation, water, energy, and government
👾 RansomHub – New RaaS Group on the Rise
A new Ransomware-as-a-Service (RaaS) operation, RansomHub, is gaining traction on underground forums. The group is recruiting affiliates and targeting organizations with double-extortion tactics—stealing data before encrypting it.
Key Traits:
-
High ransom demands
-
Fast lateral movement
-
Leverages remote desktop protocol (RDP) and phishing
Recommended Actions: Disable unused services, restrict RDP access, and monitor for lateral movement patterns.
📱 INFRA:HALT Campaign – Industrial IoT Under Attack
This campaign focuses on industrial IoT (IIoT) and SCADA systems used in manufacturing and utilities. Attackers are targeting insecure OT devices and outdated firmware.
Targets:
-
Programmable logic controllers (PLCs)
-
Human-machine interfaces (HMIs)
-
Remote terminal units (RTUs)
Advice: Patch OT environments, segment networks, and avoid internet-exposed controls.
📌 Key Takeaways for CISOs and Security Teams
-
Patch Management Must Be Proactive: Speed matters—reduce patch cycles from weeks to days.
-
Threat Intelligence Is Essential: Subscribe to curated feeds or services to stay ahead of new threats.
-
Zero Trust Is No Longer Optional: Assume breach and implement least-privilege access everywhere.
-
Employee Awareness Still Matters: Many campaigns begin with phishing. Training is your first line of defense.
-
Third-Party Risk Is Real: Monitor and secure your supply chain and vendor relationships.
🔍 Final Thoughts
The modern threat landscape is fast-moving and relentless. From backdoors in Linux tools to state-sponsored espionage and ransomware-as-a-service operations, defenders must be agile, informed, and well-prepared.
Regular roundups like this are your early-warning radar—helping you prioritize patches, recognize threat actors, and prepare your defenses before the attack hits.
