A Major Media Outlet requires confirmation that Windows 95, to facilitate
its automatic reconnect feature for sleeping laptops and temporary network
outages, caches all network passwords (NetWare, NT, UNIX running Samba,
SLIP/PPP dialup) in unprotected memory in clear text, whether you've
disabled persistent "password caching" to disk and applied the December
14th 128-bit RC4 .PWL patch, or not. There seems to be no way to turn 
this off.

The idea, of course, is that a simple trojan horse could do whatever it 
wanted with this information.

We know that this vulnerability exists in Windows for Workgroups, and
Peter wrote a little demo (on hackmsoft page below, without source), but
the APIs appear to have changed in Win95. 

So, anyone have Win95 and some time to kill, or can anyone recommend a
good DOS/Windows RAM grepper?
