More Information

Troj/PWDoor-A is a Trojan for the Windows platform.

The Trojan steals passwords from Internet Explorer sessions with certain websites and emails the stolen credentials to a remote user.

When run, Troj/PWDoor-A creates the file Direct32.dll in the Windows system folder and then runs it. The Direct32.dll file is also detected as Troj/PWDoor-A.

The following registry entries are created:

HKCR\CLSID\{BC687D94-3EA9-47F9-9C24-12F0B59DD9DC}
(default)
"Office.MyDLL.1"

HKCR\CLSID\
