The Week in Ransomware – October 30th 2020 – Hospitals under siege

This week we have seen a concerted attack against the healthcare industry by hacking groups utilizing the Ryuk ransomware. Also, we saw some large well-known companies suffer ransomware attacks that impacted their business operations.

The biggest news this week is the U.S. government warning the healthcare industry that there is “credible information of an increased and imminent cybercrime threat to U.S. hospitals and healthcare providers.” As a result of these attacks, we have seen six hospitals targeted in attacks this week, including Wyckoff Hospital, University of Vermont Health Systems, Sky Lakes Medical Center, and St. Lawrence Health System.

We also learned of ransomware attacks against well-known companies, such as furniture manufacturer SteelCase, French IT consulting firm Sopra Steria, and the Italian power company Enel Group.

Finally, an REvil representative known as UNKN stated that they earned $100 million in a year, and the infamous Maze gang has started to shut down its ransomware operation.

Now that the weekend is upon us, it is important for all companies to monitor for suspicious activity on their networks and Windows domain controllers, and proactively respond if anything is detected.
