Show βΌ
The US Department of Transportation's Federal Highway Department issued an advisory on September 10, 2025, alerting highway agencies and infrastructure firms to scan solar-powered highway infrastructure for undocumented radios hidden in batteries and inverters. These radios, while not necessarily malicious, could be exploited for malicious purposes. The advisory comes amid increasing scrutiny of supply chain risks from inexpensive goods, particularly from China. The presence of undocumented radios in critical infrastructure poses a security risk, as they could be used to gain unauthorized access or disrupt operations. This issue highlights the broader vulnerability of operational technology (OT) in critical infrastructure, which has seen an increase in ransomware attacks targeting manufacturers, energy firms, and industrial sectors.
