LOS ANGELES (AP) — The chief executive of a Los Angeles hospital says it paid a ransom in bitcoins equivalent to about $17,000 to hackers who infiltrated and disabled its computer network.

Hollywood Presbyterian Medical Center CEO Allen Stefanek said in a statement Wednesday that paying the ransom of 40 bitcoins was “the quickest and most efficient way to restore our systems and administrative functions.” He says the hospital did it in the interest of restoring normal operations.
