Hackers Disrupt Iran's Rail Service with Fake Delay Messages

TEHRAN, IRAN - Iran's railroad system came under cyberattack Friday, a semi-official news agency reported, with hackers posting fake messages about train delays or cancellations on display boards at stations across the country.  

The hackers posted messages such as "long delayed because of cyberattack" or "canceled" on the boards. They also urged passengers to call for information, listing the phone number of the office of the country's supreme leader, Ayatollah Ali Khamenei.   The semiofficial Fars news agency reported that the hack led to "unprecedented chaos" at rail stations.   No group took responsibility. Earlier in the day, Fars said trains across Iran had lost their electronic tracking system. It wasn't immediately clear if that was also part of the cyberattack.
