The NGINX access.log of my VPS is showing a curiosity.
Instead of a simple request like this...
"GET / HTTP/1.1"
...regular requests are coming in that look like this
"\x03\x00\x00\x13\x0E\xE0\x00\x00\x00\x00\x00\x01\x00\x08\x00\x03\x00\x00\x00"
Is this some kind of hack attempt?
Here's an example of a full line from the log...
15.204.204.182 - - [24/Apr/2024:15:59:47 +0000] "\x03\x00\x00\x13\x0E\xE0\x00\x00\x00\x00\x00\x01\x00\x08\x00\x03\x00\x00\x00" 400 166 "-" "-"
EDIT: For what it might be worth, most of these requests come in singularly, from different IP addresses. Once (that I've noticed) repeated attempts came in quickly from one specific IP.
