Hi everyone!!!!1

Recently came across discussions about past exploitation cases in Minecraft, specifically related to Log4Shell.

From what I’ve seen, this wasn’t anything particularly complex. Once the payload format became public, it basically turned into copy/paste. Dropping a crafted string into in-game chat was enough to trigger remote code execution on vulnerable servers.

What stands out is how low the barrier to entry was. No need to develop anything from scratch—payloads were quickly shared, reused, and even adapted by different actors. It pretty much became a plug-and-play vector.

Also worth noting that many game servers run outdated components and are poorly maintained, which makes them easy targets. Add public exposure to that, and you get a pretty wide attack surface.

Not really a “new” technique, but a good example of how fast something goes from disclosure to being used in the wild when it’s easy to replicate.

What do you all think? Have you seen similar cases where in-game features were actually leveraged for real-world exploitation?

GoldSrc and Source are among the games where RCE vulnerabilities were discovered. I seem to recall that 1.6 servers were used to distribute malware; I don't remember exactly, but it was something.
