Pwdump
Overview
Executive Summary
Pwdump is not a malware family itself, but rather a classification for a series of legitimate, highly potent penetration testing tools (HackTools) designed specifically to extract the Security Account Manager (SAM) database from Windows operating systems. When found on a corporate endpoint outside of authorized security testing, it is a critical indicator of post-compromise activity and impending credential theft.Technical Capabilities and Abuse
Pwdump (and its successors like fgdump) are command-line utilities. They are utilized by threat actors *after* they have already achieved local Administrator or SYSTEM privileges on a compromised machine. Their primary function is the extraction of password hashes:- SAM Database Extraction: The Windows SAM file stores user passwords in a hashed format (LM/NTLM). Normally, the OS locks this file, preventing standard copying. Pwdump utilizes DLL injection (often targeting the `lsass.exe` process) or specialized drivers to bypass this lock and dump the hashes directly from memory or the registry.
- Offline Cracking: Once the attacker runs Pwdump, they output the results to a text file and exfiltrate it. They can then use offline cracking tools (like Hashcat or John the Ripper) to brute-force the plaintext passwords.
- Pass-the-Hash (PtH): Even without cracking the plaintext password, an attacker can use the extracted NTLM hashes directly in a "Pass-the-Hash" attack to authenticate to other servers and pivot laterally across the Active Directory domain.
Threat Assessment
The unauthorized presence of Pwdump on a system is a critical security emergency. It unequivocally indicates that an attacker has achieved elevated privileges and is actively attempting to steal domain credentials to facilitate widespread lateral movement.Incident Response and Remediation
- Immediate Network Isolation: Isolate the compromised machine immediately to prevent the attacker from exfiltrating the dumped hashes or using them to pivot to the Domain Controller.
- Enterprise-Wide Credential Reset: If Pwdump was executed successfully, incident responders must assume that all local accounts (and potentially cached domain accounts) on that machine are compromised. A mandatory password reset must be enforced.
- Hunt for the Initial Access Vector: Pwdump is a post-exploitation tool. The investigation must focus on *how* the attacker gained the administrative privileges necessary to run it in the first place (e.g., exploiting a vulnerable service, phishing a privileged user, or lateral movement from another host).

This family has been observed using the following ATT&CK techniques: T1003.002 T1003.001 T1550.002
Tactical Mitigations
Based on the techniques used by this family, consider the following defensive strategies:
- T1003.001: Monitor for LSASS memory dumping or registry SAM extraction. Enable Credential Guard on Windows systems.
- T1003.002: Monitor for LSASS memory dumping or registry SAM extraction. Enable Credential Guard on Windows systems.

Frequently Asked Questions
How do I remove the Pwdump Advanced_Threat from Windows?
Manual removal of Pwdump is highly discouraged as it may leave persistence mechanisms intact. We recommend disconnecting the device from the internet and utilizing a professional incident response service or enterprise-grade EDR software to conduct a full forensic sweep.
Is Pwdump a virus or a Advanced_Threat?
Pwdump is classified as a Advanced_Threat. Unlike traditional viruses that infect files, modern malware like Pwdump typically operates as a standalone payload designed to compromise systems, steal data, or deploy secondary stage implants.
What are the main symptoms of a Pwdump infection?
Symptoms of Pwdump can include unexpected system slowness, unauthorized outbound network traffic to unknown IP addresses, disabled security software, and suspicious background processes running from AppData or Temp directories.
