This tutorial demonstrates exploiting a publicly exposed Redis service on Hack The Box’s Redeemer machine. It covers scanning for Redis with nmap, interacting with Redis using redis-cli, listing keys, and extracting values (including the flag). The article also provides an automation script in Bash to streamline the process. Key takeaways include the importance of checking for unauthenticated access on Redis installations, running INFO and KEYS * commands for enumeration, and automating repetitive tasks with scripts. The tutorial concludes by suggesting further steps such as integrating Redis checks into Recon automation and exploring authenticated Redis attacks for learning and practice.
