I Scan, You Scan, Everyone Bloody Scans

Right, so the good folks at Cisco Talos decided to poke the festering corpse of internet scanning again, because apparently, the world doesn’t have enough digital roaches crawling the goddamn network pipes already. These maniacs went spelunking through a mountain of data to figure out who’s been scanning whom — from the well-meaning researchers trying to make the world slightly less on fire, to the cyber-scum trying to set it ablaze anyway.

Basically, every bastard with an internet connection and a packet generator seems to be probing, poking, and sniffing their way across the globe. The Talos team looked at all this noisy nonsense and tried to tell the difference between the dubious dickheads and the legit nerds. They even dropped their findings publicly so that others can avoid reinventing the wheel — or worse, getting blindsided by the same lazy-ass botnets.

The whole bloody point? Knowing who’s scanning your crap means you can decide whether to swat them like the little digital gnats they are, or give them a grudging nod for doing something vaguely useful. Because yes, even though these constant scans make your logs look like a drunken ant farm, some of them might actually be trying to protect the infrastructure before the next script kiddie turns it into a crypto-mining toilet.

So the takeaway from Talos: The internet is a noisy hellhole, but at least someone out there is trying to sort through the chaos instead of adding to it. The biggest surprise? Half the so-called security scanners are about as subtle as a sledgehammer tap-dancing across a minefield. Yet, somehow, we’re still shocked when servers start coughing up data like hairballs. Bloody amateurs.

Reminds me of the time some intern decided to “scan” our own stack to “see what was open.” Poor sod brought down half the network and then tried to blame “latent vulnerabilities.” Latent my arse — you nuked DHCP because you thought nmap was a toy. I made him trace cables for a week. In production. Without coffee.
