The email didn’t look suspicious. It had none of the hallmarks of a scam, like bad spelling or laughable grammar. And it wasn’t asking for money – in fact, it appeared to come from a high-ranking executive in the hospital.
The well-meaning employee opened the link. You can guess what happened next. It was ransomware, a malicious piece of code that encrypts or locks files, preventing access to mission-critical applications until the victim pays a fee. The hospital had to shut down all computers for a few days but eventually got back online without paying the ransom. Many other facilities aren’t as lucky.
