Overview

Summary:

Once in memory the DR_MODEM.exe and Amdupd.dll must be deleted in a dos session before Windows startup. Also the registry entry needs to be deleted: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run] 'Modem Doctor'='C:\\WINDOWS\\DR_MODEM.EXE'

Category:

Key Logger: (Keystroke Logger). A program that runs in the background, recording all the keystrokes. Once keystrokes are logged, they are hidden in the machine for later retrieval, or shipped raw to the attacker. The attacker then peruses them carefully in the hopes of either finding passwords, or possibly other useful information that could be used to compromise the system or be used in a social engineering attack. For example, a key logger will reveal the contents of all e-mail composed by the user. Keylog programs are commonly included in rootkits and RATs (remote administration trojans).

Password Capture: A variant of the Key Logger that captures passwords as they are entered or transmitted. Some password capture trojans impersonate the login prompt, asking the user to provide their password.
