Hollywood Presbyterian Medical Center paid $17,000 to cyberattackers who crippled its network by encrypting its files. Hollywood Presbyterian’s CEO: “In the best interest of restoring normal operations, we did this” Ransomware attacks have been occurring for more than a decade, but only in the last couple of years have the attacks become large scale. The style of attack, known as ransomware, has become increasingly common, affecting companies, organizations and individuals. The best insurance is to have offline or segregated backups of data, the CEO says.”]
