Trojan Alert was: Check this

Can someone with a lucky hand in Visual Basic actually tell us what the trojan attachment we saw (LINKS2.VBS) we saw (full mail headers included, in case Shawn hasn't seen them yet) actually does. Seems to cloak itself well, and my Norton AV is *not* detecting anything. On another operational note: I am seeing a vastly swelling number of customers falling victim to the NETWORK.VBS worm: a simple VB script that first scans surrounding network space for open, writable windows shares (and replicates by copying itself into a shared C:\ drive, if such drive is shared), then goes on to randomly scan /24's , where the 3 first octets of the IP number are random: this is generating boatloads of violations in my "no RFC1918 in or out" filters (and this is how this came to my attention). We found a user who had scanned a stunning 9980 /24's this way : there is a C:\network.log (or was it .txt) file showing the scan activity. bye,Kai
