“A Los Angeles hospital paid a ransom in bitcoins equivalent to about $17,000 to hackers who infiltrated and disabled its computer network, the medical center’s chief executive said Wednesday.

It was in the best interest of Hollywood Presbyterian Medical Center to pay the ransom of 40 bitcoins — currently worth $16,664 dollars — after the network infiltration that began Feb. 5, CEO Allen Stefanek said in a statement.

The FBI is investigating the attack, often called “ransomware,” where hackers encrypt a computer network’s data to hold it “hostage,” providing a digital decryption key to unlock it for a price.

“The quickest and most efficient way to restore our systems and administrative functions was to pay the ransom and obtain the decryption key,” Stefanek said. “In the best interest of restoring normal operations, we did this.”

Ransomware attacks can happen to everyone from individuals to large institutions.

Bitcoins, the online currency that is hard to trace, were quickly becoming the preferred way hackers collect a ransom, FBI Special Agent Thomas Grasso, who is part of the government’s efforts to fight malicious software including ransomware, told The Associated Press last year.

During 2013, the number of attacks each month rose from 100,000 in January to 600,000 in December, according to a 2014 report by Symantec, the maker of antivirus software.

A report from Intel Corp.’s McAfee Labs released in November said the number of ransomware attacks is expected to grow even more in 2016 because of increased sophistication in the software used to do it.

The company estimates that on average, 3 percent of users with infected machines pay a ransom. It’s not clear how many of those users were individuals and how many companies. Some ransomware attacks go unreported because the victims don’t want it publicized they were hacked.

Workers at Hollywood Presbyterian noticed the network problems on Feb. 5, and it became clear there was a malware infiltration that was disabling the network.

Computer experts and law enforcement were immediately informed, Stefanek said. On Monday, 10 days after the attack, the network was in full operation again, he said.

FBI spokeswoman Laura Eimiller said the agency is investigating the extortion plot, but she could not immediately provide further details.”
