Seriously? Webshells *Again*?!

Right, so some script kiddie – probably using a pre-made kit because thinking is hard for them – figured out they can hide webshells in the .well-known/ directory. Yeah, brilliant. Like nobody’s ever thought of that before. It’s basically exploiting the fact that web servers are SUPPOSED to serve files from there without much fuss, specifically for things like Let’s Encrypt and other legit stuff.

The gist? They’re sticking malicious PHP code in .well-known/acme-challenge/ or similar subdirectories. Because why bother with actual security when you can just dump crap where people least expect it, right? It bypasses some basic scanning rules because scanners often ignore that directory thinking “oh, it’s for ACME challenges, leave it alone!”.

They’re seeing this in compromised WordPress sites mostly. Shocking. Absolutely fucking shocking. The article says to look for unusual files in .well-known/ and check your web server logs like a grown up. Also, keep your shit updated. Seriously, update everything. It’s not rocket science.

And of course, they’re using this as an excuse to push more WAF rules. Wonderful. More layers of bullshit to slow down legitimate traffic because some idiot couldn’t secure their WordPress install.

Honestly, I’m starting to think the internet deserves what it gets.

Related Anecdote: Back in ’98, I had a user who thought hiding files inside image GIFs was a good security measure. “They’ll never look *in* the picture!” he said. I swear to god. Some people are just… beyond help.
