Ryuk Ransomware attacks shut down newspaper printing facilities, cloud hosting firm. Check Point Research found that Ryuk shared some of the same source code as another piece of ransomware called Hermes. Ryuk is a much more targeted piece of malware that specifically encrypts critical systems within a network. CrowdStrike’s analysis points to several factors linking the group to Ryuk, including that fact that Russian-speaking forums began circulating information about the source code, and that the ransomware did not work in Russia, the Ukraine or Belarus.”]
