An obfuscated password isn’t necessarily a protected password.
During a recent assessment, we found SQL Server credentials stored in a Lobster Data configuration file using the OBF: format. Jetty’s standard decoding utility couldn’t recover the password, so we dug into the application’s Java libraries.
After reverse engineering the custom obfuscation routine, we built “Lobster Pot” - a standalone Python tool to recover the plaintext password. 🦞
Those credentials helped enable lateral movement and privilege escalation, ultimately leading to a Domain Admin foothold.
Our latest post breaks down the discovery, the reverse engineering, and why obfuscation fell short.
