Ryuk is a piece of ransomware that was first observed in August 2018 and has been in the news since then. Among its victims, companies from different industries such as famous newspapers, restaurants, public institutions and a cloud service provider have been reported. Ryuk has been observed along with Emotet and Trickbot, two of the most widely spread threats that are currently being used in malware campaigns. What makes Ryuk interesting is the fact that is being used in targeted campaigns, dropped days or weeks after a victim was first compromised, and its ties with threat actor groups. At first, security researchers believed the Ryuk ransomware was tied to North Korean actors because its code was similar to Hermes, another ransomware that was used by infamous threat actor Lazarus. Four months later, that theory was discarded, and it was attributed to Russian-speaking actors dubbed Grim Spider. This paper will review Ruyk's technical aspect since its appearance, and how it has evolved through the year.
