The evolution of ransomware

  • 1989: PC Cyborg. Hid files and encrypted names; asked users to pay $189 to get 'repair tool'
  • 1996: Researchers Adam Young and Moti Yung showed that PC Cyborg wasn't very effective, because the key was easy to recover without paying. They released a proof-of-concept cryptovirus that used stronger encryption, and they noted that such an attack could be used for extortion
  • By 2005: really the rise of ransomware. Multiple versions with greater key sizes
  • 2008: first considered unbreakable with 1024 bit RSA key: Gpcode.AK
  • Today: multiple variants like CryptoLocker, CryptoWall
