Concerns Over Supply Chain Attacks on US Seaports Grow

The House Select Committee on the CCP found that roughly 80% of US ship-to-shore (STS) cranes are manufactured by Chinese state-owned ZPMC, whose crane systems have reported software vulnerabilities and retain remote cellular access. Although investigators did not find evidence of deliberate malicious use, the report warns this concentrated dependence and unpatched, remotely accessible equipment create significant cyber-physical supply-chain risks to US ports and recommends disabling cellular modems, monitoring vendor access, and assessing domestic manufacturing options.
