Ohhhh! So that's how the blackhatters get into the Linux OS, through UFW's exploit holes to the kernel.. Thanks for the heads-up piece of data warning us about the exploit properties of UFW... Seems we must configure UFW and Librewolf to be much stronger..
Everything state of the art these days can leak through UFW like it's a coarse sieve.. Using UFW without configuring it you would have as much security as if you typed on the screen in large red letters "BAD GUYS KEEP OUT!"..

microterror can see right through and reach right in through UFW and the kernel with Firefox like the firewall wasn't even there, is why microterror's policy enforcers and venomous web-serpents don't want us to remove Firefox in-favor of us installing Librewolf for REAL security, to enforce undesired honesty on it...

Badi is probably part of the why.. This is some of the secret depth of the why.. medium.com/hackernoon/migrating-wemove-co-from-azure-to-ubuntu-vm-on-digital-ocean-96280ce24777
