According to software supply chain security company Socket, the packages were published in 2023 and 2024 by a user named " shanhai666" and are designed to run malicious code after specific trigger dates in August 2027 and November 2028. The packages were collectively downloaded 9,488 times. "The most dangerous package, Sharp7Extend, targets industrial PLCs with dual sabotage mechanisms: immediate random process termination and silent write failures that begin 30-90 minutes after installation, affecting safety-critical systems in manufacturing environments," security researcher Kush Pandya said.
The victims included a municipal water facility where pressure values were changed, an oil and gas company whose tank gauge was tampered with, and a farm silo where drying temperatures were altered, "resulting in potentially unsafe conditions if not caught on time." Officials stressed these weren't sophisticated, state-sponsored operations but opportunistic intrusions that caused real-world disruption ranging from false alarms to degraded service. The attackers didn't need custom malware or insider access either - just a connection and curiosity.
Red Lion's Sixnet RTUs provide advanced automation, control, and data acquisition capabilities in industrial automation and control systems, primarily across energy, water, and wastewater treatment, transportation, utilities, and manufacturing sectors. These industrial devices are configured using a Windows utility called Sixnet IO Tool Kit, with a proprietary Sixnet "Universal" protocol used to interface and enable communication between the kit and the RTUs.
NIST has published a new guide designed to help organizations reduce cybersecurity risks associated with the use of removable media devices in operational technology (OT) environments. NIST Special Publication (SP) 1334 was authored by the National Cybersecurity Center of Excellence (NCCoE) and it focuses on the use of USB flash drives, but also mentions other types of removable media such as external hard drives and CD/DVD drives.
