PolyU finds cross-domain attack via EV charging navigation can strain the grid

Researchers at Hong Kong Polytechnic University (PolyU) described a cross-domain cyberattack in which manipulating EV charging navigation redirects many vehicles to a single station, concentrating demand in a short window. This can trigger local outages and degrade grid reliability without breaching the guarded power communication network.

• The attack does not require breaching the guarded power communication network
• Manipulating charging navigation concentrates demand in a short period
• Consequences include local outages and lower grid reliability
