There is a cybersecurity firm that published a
blog post claiming they figured over 50% of the airports workstations were riddled with a crypto mining software despite the fact the workstations have 'industry-standard' antivirus and were not able to detect it.
They don"t know since how many times the malware was in place because they just started to work with the airport, so possibly for months. The airport didn't notice anything before.
In a worst-case scenario, attackers could have breached the IT network as a means to hop onto the airports OT network in order to compromise critical operational systems ranging from runway lights to baggage handling machines and the air-train, to name a few of the many standard airport OT systems that could be cyber-sabotaged to cause catastrophic physical damage.
I wonder how many others are actually targeted like this one.
