Schneider has fixed three vulnerabilities in one of its popular electric car charging stations, which security researchers said could have easily allowed an attacker to remotely take over the unit.

At its worst, an attacker can force a plugged-in vehicle to stop charging, rendering it useless in a “denial-of-service state,” an attack favored by some threat actors as it’s an effective way of forcing something to stop working.
