Previously, there was no throttling on repeated authentication attempts
to the charging station backend, which could allow an attacker to
execute a denial-of-service attack.
Hydro-Québec has updated the majority of charging stations to disable
OCPP, mitigating the risk of exploitation. Hydro-Québec has also
implemented authentication systems to mitigate the issue for certain
charging stations which are still reliant on OCPP. Contact Hydro-Québec
with any additional questions.
