The first ransomware for Mac OS X has been found.
MetaFilter: OS X Ransomware. “First OS X ransomware detected in the wild, will maliciously encrypt hard drives on infected Macs.”
“OS X users have today been hit with the first known case of Mac â€˜ransomware’ malware, found in the Transmission BitTorrent client released last week. Infected versions of the app include â€˜KeyRanger’ malware that will maliciously encrypt the user’s hard drive after three days of being installed. The malware then asks for payment to allow the user to decrypt the disk and access their data — the â€˜ransom’.”
Ransomware has been around for several years in one form or another, but seems to have become much more popular in the past few months. One of my favorite podcasts reported on this problem back in the fall:
Radiolab on September 21, 2016: Darkode.
“It would seem that hackers today can do just about anything they want – from turning on the cellphone in your pocket to holding your life’s work hostage. Cyber criminals today have more sophisticated tools, have learned to work collaboratively around the world and have found innovative ways to remain deep undercover in the internet’s shadows. This episode, we shine a light into those shadows to see the world from the perspectives of both cybercrime victims and perpetrators.”

Deutsche Welle on February 25, 2016: Hackers hold German hospital data hostage.
“Several hospitals in Germany have come under attack by ransomware, a type of virus that locks files and demands cash to free data it maliciously encrypted. It will take weeks until all systems are up and running again.”
Die Zeit: Wir haben Eure Daten! “Eine neue Form der Erpressung hat sich etabliert. Cyberkriminelle legen Computer lahm und verlangen Lösegeld. Was passiert, wenn es ein Krankenhaus trifft – eine Rekonstruktion.” Von Karen Grass.
