T1003: Credential Dumping Mitigation
### Windows Monitor/harden access to LSASS and SAM table with tools that allow process whitelisting. Limit credential overlap across systems to prevent lateral movement opportunities using Valid Accounts if passwords and hashes are obtained. Ensure that local administrator accounts have complex, unique passwords across all systems on the network. Do not put user or admin domain accounts in the local administrator groups across systems unless they are tightly controlled, as this is often equivalent to having a local administrator account with the same password on all systems. Follow best practices for design and administration of an enterprise network to limit privileged account use across administrative tiers. [1]
On Windows 8.1 and Windows Server 2012 R2, enable Protected Process Light for LSA. [2]
Identify and block potentially malicious software that may be used to dump credentials by using whitelisting [3] tools, like AppLocker, [4] [5] or Software Restriction Policies [6] where appropriate. [7]
With Windows 10, Microsoft implemented new protections called Credential Guard to protect the LSA secrets that can be used to obtain credentials through forms of credential dumping. It is not configured by default and has hardware and firmware system requirements. [8] It also does not protect against all forms of credential dumping. [9]
Manage the access control list for “Replicating Directory Changes” and other permissions associated with domain controller replication. [10] [11]
Consider disabling or restricting NTLM traffic. [12]
### Linux Scraping the passwords from memory requires root privileges. Follow best practices in restricting access to escalated privileges to avoid hostile programs from accessing such sensitive regions of memory.
This ATT&CK object is revoked or deprecated in the current MITRE ATT&CK release.
It remains available for historical context and inbound links. Use current ATT&CK relationships and replacement guidance before basing detection or reporting work on this page.
Analyst summary pending validation
Glexia publishes ATT&CK takes only after source-hash and schema validation. Until then, use the official MITRE definition below and the defensive relationship context on this page.

Object version and sync metadata
The fields below describe the current mirrored snapshot. When Glexia retains multiple ATT&CK source imports, you can open the table to compare the same object across releases (hashes and MITRE timestamps). For MITRE’s own release notes and roadmap, see ATT&CK resources — Updates .
Imported snapshots across ATT&CK releases (1)
| Release | Bundle imported | Object version | Modified | Status | Raw hash |
|---|---|---|---|---|---|
| 19.1 | 1.0 | Current bundle Deprecated | b6d6ede881f2… |
Mirrored ATT&CK source object
The raw object is retained through the mirrored ATT&CK source bundle and object hash. The raw endpoint returns the exact object from the mirrored bundle when available.
External references and citations
MITRE external references are preserved separately from Glexia analysis so citations remain traceable to their original source records.
