Hollywood Presbyterian Medical Center

Hollywood Presbyterian Medical Center paid a $17,000 ransom in bitcoins to a hacker who seized control of the hospital’s computer systems and would give back access only when the money was paid, the hospital’s chief executive said Wednesday.

The cyberattack on Hollywood Presbyterian occurred Feb. 5, when hackers using malware infected the institution’s computers, preventing hospital staff from being able to communicate from those devices, said CEO Allen Stefanek.

The hacker demanded 40 bitcoins, the equivalent of about $17,000, he said.

The hospital said it alerted authorities and was able to restore all its computer systems by Monday with the assistance of technology experts.

Stefanek said patient care was never compromised, nor were hospital records.
