Nosu is a ransomware strain that encrypts the victim's files and demands payment in exchange for the decryption key. It operates by spreading through infected email attachments and network shares, and can cause significant data loss and downtime for affected organizations.
Nosu operates with stealth, leveraging custom tools that allow for long-term access. To mitigate this, organizations should segment networks to prevent lateral movement and ensure all sensitive data is protected by strict access control policies. Regular patching and monitoring of all endpoints can help identify and mitigate any potential vulnerabilities early. Threat intelligence sharing and advanced detection systems should be employed to monitor for indicators of compromise (IOCs) linked to Nosu.
