💧Forescout disclosed that a Russia-aligned hacktivist group, TwoNet, was tricked into attacking a honeypot designed to look like a water treatment utility. The actor accessed the HMI with default credentials and created an account named BARLATI to carry out defacement, PLC manipulation, log suppression and process disruption. Forescout said this incident reflects a broader shift from DDoS and defacement toward OT/ICS targeting and provided mitigation guidance.

🚗 Modern vehicles increasingly rely on interconnected electronics and external services, creating multiple remote attack vectors — from CAN, LIN and OBD ports to Wi‑Fi, Bluetooth and cellular links. The article notes that attackers now often target manufacturer servers (e.g., Toyota’s 2024 data loss) and references UN R155/R156 and ISO/SAE 21434. It describes vehicle risk categories, practical buyer and setup checks, and step‑by‑step advice if you suspect a compromise.

🔍 Forescout observed pro‑Russian hacktivist group TwoNet compromise a realistic water‑treatment honeypot in September, moving from initial access to disruptive actions in roughly 26 hours. The attackers used default credentials and SQL enumeration, then exploited a stored XSS (CVE-2021-26829) to display the message "Hacked by Barlati," altered HMI PLC setpoints and disabled real‑time updates and logs. Researchers urge strong authentication, network segmentation, IP-based ACLs for admin interfaces, and protocol-aware detection to spot exploitation and HMI changes.

🔒 Manufacturers face growing, targeted cyber threats driven by legacy OT, complex supply chains, and high-value IP. Attackers increasingly use credential theft, social engineering and sophisticated malware to achieve prolonged access, data theft and ransomware extortion that can halt production and ripple across partners. Building resilience with MFA, prompt patching and continuous detection such as MDR — offering 24/7 threat monitoring, expert hunting and rapid containment — reduces downtime and strengthens supply chain security while aligning with Zero Trust principles.
