According to 8Signs Firewall [ http://www.8signs.com/index.cfm ], a tarpit is a trap for troublesome outsiders. Your system accepts TCP connections but never replies and ignores disconnect requests. This can leave ports scanners and hackers stuck for hours, even days.
Sounds like a black hole port…
This is not likely to have much impact on botnets where the hacker is not too concerned that you strangle one of the bots. It’s NOT his computer that is tied up…
Would the infected computer be handicapped enough for the innocent victim of a worm to notice?
Hey, we’d probably just blame our ISP for bad service or our security software for slowing us down!!!
Those are more likely anyway, even if many tarpits are in operation
