We at Tenable use a similar method. I wrote a simple NASL that gets
DefaultUserName. It uses SMB to login and get registry access, then
just grabs DefaultUserName from the registry. This works on all our
corporate laptops, won't work well on mulit-user systems such as an
AD or Exchange Server. We added this NASL to our OS ID scan, and then
we use Security Center's Asset List functionality to create an asset
list for each user.
key = "Software\Microsoft\Windows NT\CurrentVersion\Winlogon"; item =
"DefaultUserName";
key_h = RegOpenKey(handle:hklm, key:key, mode:MAXIMUM_ALLOWED); if ( !
isnull(key_h) ) {
value = RegQueryValue(handle:key_h, item:item);
if (value[1] != "") && (value [1] != NULL){
rep = "DefaultUserName:" + value[1];
security_note (port, data:rep);
RegCloseKey(handle:key_h);
