I'll let you in on a little secret, too: bad actors talk to each other! They exchange information about the exploits. So you already *potentially have* 10000 of them trying to exploit the vulnerability, with the most of the affected people being none-the-wiser. I'd rather know, so I can do something to avoid or repair the damage, instead of figuring out my systems might have been compromised for weeks. If you want to sit in the dark - feel free, just don't take me with you. M. -- .... *** System shutdown message from root *** System going down in 60 seconds
