The ransomware landscape has witnessed many notorious groups, over the years, that became a security nuisance for every organization. Adding to that list, the FBI warned of the Cuba ransomware group that has targeted 49 organizations across five critical infrastructure sectors and gathered millions in ransom payments. Meanwhile, a new cryptomining campaign was found abusing Github and Netlify to distribute a Monero miner and other malicious tools.

Energy and healthcare are two of the most critical sectors for every nation. Last weekend, an American electric utility company disclosed a destructive ransomware attack that resulted in massive data loss and billing disruption. Meanwhile, the data of thousands of U.S. healthcare workers was left exposed due to an unsecured database.
