We had one user report our DNS servers were hacking his system. Knew enought to do a whois but didn't have any clue beyond that. :) (lots of port 53 activity in the logs every time he surfed the web...)

I've seen supposed "security professionals" for theoretically clued places like NASA send abuse complaints over traceroutes they've originated, and people complain about "port 80 hacking attempts" then flatly refuse to admit they visited website. At best, it's annoying clutter. Is it any wonder that legitimate emails about ongoing DoS attacks are completely ignored or responded to a week later? At worst, it can get innocent people in trouble and cost them a lot of time, effort, and potentially money. These false abuse reports are FAR too common, and the net equivilent of crying wolf. In my opinion, it is the responsability of these personal firewall makers to at least make an EFFORT to warn their users about this. So far, I havn't seen it. -- Richard A Steenbergen <[email protected]> http://www.e-gerbil.net/ras PGP Key ID: 0x138EA177 (67 29 D7 BC E8 18 3E DA B2 46 B3 D8 14 36 FE B6)
