If you have used Linux for some time, you have likely ran a command that looks something like this:
curl https://some.random.web.site/script | sudo bash
But what if I told you...
that running such a command is DANGEROUS and PUTS YOUR SYSTEM AT RISK?????????
Well, the script you're executing might contain literally any commands. So an attacker might put rm -rf / (which is a command I definitely do not recommend running!) in the script and pai pai system forever!
One word:
readInstead of running some random commands on your system, take some time out of your day to actually read the script and review what it's doing. It'll take like ten minutes at most anyway.
