Fire Rescue Victoria has confirmed it is the victim of a cyber attack but insists public safety has not been compromised.
The hack has impacted most of its IT systems including dispatch, phones, email and an important automated system that opens station doors as soon as a call out is received.
"Preliminary investigations confirm this has been a cyber-attack by an external third party and that FRV systems are impacted," a spokesperson for the fire service said on Friday.
