'You hacked': Terminals throughout the San Francisco public transit system displayed this message to riders on Nov. 26: "You hacked. ALL data encrypted." According to the local CBS affiliate, the hack took terminals and ticket kiosks offline, and the city's transit agency responded by waiving fare on Saturday while those systems were affected (actual transit lines remained operational). To some commuters, the hack was worrying; to others, it was a blessing. “I was like, is this part of Black Friday deal, or something?” one rider told CBS.

Ransomware's big social media push: Users of Facebook and LinkedIn are being targeted with a malware attack called Locky, which — true to its name — locks up and encrypts users' files before demanding a ransom of half a bitcoin ($365), Ars Technica reports.

Though Locky has been around for much of the year spreading through Word documents and spam e-mails, in November it began its aggressive social media push.
