Ransomware Compromises San Francisco's Mass Transit System (cbslocal.com)
Buses and light rail cars make San Francisco's "Muni" fleet the seventh largest mass transit system in America. But yesterday its arrival-time screens just displayed the message "You Hacked, ALL Data Encrypted" -- and all the rides were free, according to a local CBS report shared by RAYinNYC:
Inside sources say the system has been hacked for days. The San Francisco Municipal Transportation Agency has officially confirmed the hack, but says it has not affected any service... The hack affects employees, as well. According to sources, SFMTA workers are not sure if they will get paid this week. Cyber attackers also hit Muni's email systems.
Though the article claims "The transit agency has no idea who is behind it, or what the hackers are demanding in return," Business Insider reports "The attack seems to be an example of ransomware, where a computer system is taken over and the users are locked out until a certain amount of money is sent to the attacker." In addition, they're reporting the attack "reportedly included an email address where Muni officials could ask for the key to unlock its systems."
One San Francisco local told CBS, "I think it is terrifying. I really do I think if they can start doing this here, we're not safe anywhere."

not a hard feat to pull off. the data thats shown on these screens is either dynamically generated by track signal data thats processed through SCADA and into a windows system, or you can issue an override screen for construction/etc...removing this screen should not be hard.
and all the rides were free
there is no magic button to make all rides free centrally. This was likely done by Muni as a last ditch effort because their card transaction databases were offline or the system that handles accounting for this database was offline due to the hack. Muni simply put their turnstiles into bypass mode and sent their fare enforcement officers home for the day. it means when they run their fare-jump report for the month, theyll have to adjust for the days they had open fare points.
"The transit agency has no idea who is behind it, or what the hackers are demanding in return,"
nothing. chances are great they didnt expect to get this far. its possible the warning on muni transit screens is a side-effect of a wallpaper or start screen that machines are now forced into depending on what model of annunciation system they purchased. if thats the case, reimaging the screens will take 2-3 hours and can all be done centrally. as for the accounting database for oyster/muni cards, thats an easy restore from backup or calling transactions back from their VAN provider (value added networks, generally operated by IBM or Cisco.)
as for people worrying about getting paid, this happens a lot. ive once shut down live map systems on a handful of busses to upgrade the video drivers, and by the end of the day there was a rumor spreading that the payroll department was hacked. Drivers/operators are not brilliant minds.
Good people go to bed earlier.
No foreigner would write "You hacked", no matter how poor their English is.
All your bus are belong to us
