17,000 ransom in bitcoin to a remove bitcoin virus 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 assault on Hollywood Presbyterian occurred Feb.

The Hollywood Presbyterian Medical Center¬†in 2004. The hospital was recently¬†the target of a ransomware extortion plot in which hackers seized control its computer systems and then demanded that directors pay in bitcoin to regain access. 5, when hackers using malware infected the institution’s computers, preventing hospital staff from being able to communicate from those devices, said Chief Executive Allen Stefanek. The malware locks systems by encrypting files and demanding ransom to obtain the decryption key. In the best interest of restoring normal operations, we did this. The hospital said it alerted authorities and was able to regain control of all its computer systems by Monday, with the assistance of technology experts.

Stefanek said patient care was never compromised, nor were hospital records. Laura Eimiller, an FBI spokeswoman, said the bureau has taken over the hacking investigation but declined to discuss specifics of the case. Law enforcement sources told The Times that the hospital paid the ransom before reaching out to law enforcement for assistance. The attack forced the hospital to return to pen and paper for its record-keeping. Phil Lieberman, a cybersecurity expert, said that, while ransomware attacks are common, targeting a medical institution is not. I have never heard of this kind of attack trying to shut down a hospital. Health management systems are beginning to tighten their security.
