Solution
XEye Security's digital forensics team was promptly deployed to assist the client. The following steps were undertaken to address the situation:
1. Initial Assessment and Coordination:
Engaged with the client's IT team to understand the scope of the ransomware attack and ensured that the instructions to keep all infected devices powered on were strictly followed, as shutting down could complicate the recovery process.
2. Containment and Evidence Collection: Isolated infected systems from the network to prevent further spread of the ransomware and collected system logs, memory dumps, and other crucial data to understand the ransomware's behavior and entry point. .
3. Decryption Key Discovery: Conducted a thorough investigation of the infected systems to identify any clues or weaknesses in the ransomware's encryption scheme, Leveraged specialized forensic tools and techniques to dissect the ransomware's code and communication with the command-and-control server, and successfully located the decryption key embedded within the ransomware code, an approach that negated the need to engage with the attackers.
4. Data Recovery and Incident Reporting: Utilized the decryption key to restore encrypted data, ensuring minimal data loss and downtime, conducted a complete forensic analysis to ensure all traces of the ransomware were eliminated from the network, and documented the entire incident, providing a detailed report outlining the attack, the response, and the preventive measures recommended.
