While conducting incident response in early 2021, the French National Cybersecurity Agency (ANSSI) identified a new “Ryuk” ransomware variant that has the capability to self-propagate across victim networks. The variant was specifically observed targeting Windows systems in ransomware campaigns at the beginning of the year (2021). This Ryuk variant can wake up powered-off systems and move through victim networks using scheduled tasks. This enables Ryuk to infect as many hosts as possible, further incentivizing a victim payout. If proven an effective tactic, other ransomware variants could develop similar “wormable” capabilities where those developers have the technical sophistication to do so.
