University Hospital New Jersey in Newark, New Jersey, paid a $670,000 ransom demand this month to prevent the publishing of 240 GB of stolen data, including patient info. The attack occurred in early September by a ransomware operation known as SunCrypt, who steals unencrypted files and encrypts all of the data. A representative of the hospital contacted the threat actors via their dark web payment portal to negotiate the stopping of any further publishing of patient data. After a series of back-and-forth negotiations, they agreed to a ransom of $672,744, or 61.90 bitcoins.
