In early February, Hollywood Presbyterian Medical Center in Los
Angeles made a $17,000 ransom payment in bitcoins to a malware hacker
who seized control of the hospital's computer systems and demanded money
ransom as a condition to returning access. The cyberattack occurred
Feb. 5, when hackers using malware infected the institution's computers,
preventing hospital staff from being able to communicate from those
devices. The malware locked key systems by encrypting files, rendering
them unusable by staff. Without the decryption key from the hackers, the
hospital had no access to its own systems .
According to the chief executive officer, “[t]he quickest and most efficient way to restore our systems and administrative functions was to pay the ransom and obtain the decryption key.” The hospital said it alerted authorities and was able to restore all its computer systems with the assistance of technology experts, but the episode lasted 10 days. Early reporting indicated there was no evidence that any patient or employee information was subject to unauthorized access, however only time will tell whether the Hospital's security controls were robust enough to prevent such losses. Regardless of whether there was any data loss, one consequence is clear—the event disrupted operations and forced the hospital to return to pen and paper for its record-keeping for an extended period. The hackers are totally anonymous and there have been no reports of suspects.
Ransomware is a fast-growing problem for all organizations, not just hospitals.
