At least the Russian and Iranian operatives attempting to influence public opinion in advance of the election have ideological goals. Not so with a more dangerous class of hackers — freelancers willing to kill for money.

Federal officials warned last week of a new wave of online extortion attempts directed at hospitals and other health care facilities.

Their technique is simplicity itself: Hack into a hospital’s main computer, take control of it, then inform management that unless a “ransom” fee is paid, the computer will be shut down or crippled.

Because we use technology to control so many things these days, including critical health care equipment, such action can be life-threatening. Just think for a moment of what could happen if, in the middle of an operation, surgeons suddenly found the electricity cut off. Even access to computerized medical records can be a matter of life and death.

Don’t doubt that the criminal hackers can — and will — do it. In September a ransomware assault nearly crippled about 250 health care facilities run by Universal Health Services. According to The Associated Press, that forced “doctors and nurses to rely on paper and pencil for record-keeping and slowing lab work. Employees described chaotic conditions impeding patient care, including mounting emergency room waits and the failure of wireless vital-signs monitoring equipment.”

Such an attack is dangerous at any time. Now, with some hospitals dealing with a surge of COVID-19 patients, a ransomware assault could kill.

But the evildoers don’t care. In fact, the more dangerous their schemes, the more likely they are to be paid the money they demand.
