REvil Ransomware Operations and Impact

Summary: REvil, a ransomware-as-a-service (RaaS), operated on a revenue-sharing model with affiliates, typically splitting ransoms 60/40 or 70/30. Affiliates gained access to target networks, sometimes through initial access brokers, escalated privileges, stole data, and deployed the ransomware. REvil provided the malware, decryption tools, infrastructure for communication, money laundering, and other backend services. This turnkey solution facilitated widespread attacks, with some notable victims, including the Texas government in 2019. Insights:

• RaaS operations involve distinct roles and a collaborative ecosystem, with affiliates responsible for the attack's execution and REvil managing the technical and logistical backend.
• The revenue-sharing model incentivized affiliates to target high-value entities, leading to significant financial gains for both parties involved.
• REvil's comprehensive infrastructure, including decryption tools and money laundering services, made it a highly effective and attractive option for cybercriminals. Proper Nouns:
