T1547.002: Authentication Package

Adversaries may abuse authentication packages to execute DLLs when the system boots. Windows authentication package DLLs are loaded by the Local Security Authority (LSA) process at system start. They provide support for multiple logon processes and multiple security protocols to the operating system.[1]

Adversaries can use the autostart mechanism provided by LSA authentication packages for persistence by placing a reference to a binary in the Windows Registry location HKLM\SYSTEM\CurrentControlSet\Control\Lsa\ with the key value of "Authentication Packages"=<target binary>. The binary will then be executed by the system when the authentication packages are loaded.

Executive priority

T1547.002: Authentication Package is an official MITRE ATT&CK technique. Glexia treats it as defensive behavior context for prioritizing monitoring, control validation, and response planning without using the object by itself as an attribution claim.

Technical view

Security teams should validate T1547.002: Authentication Package by reviewing the official ATT&CK relationships, mapped tactics (persistence, privilege-escalation), supported platforms (Windows), and available local telemetry before making detection or mitigation decisions.

Likely telemetry

  • Official ATT&CK relationships and object metadata
  • Identity, privilege, and authentication events
  • Network, endpoint, and security-tool telemetry

Detection direction

  • Validate whether T1547.002: Authentication Package appears in your detection coverage and tabletop scenarios.
  • Use the object to align executive risk language with SOC, incident response, and detection engineering work.
  • Do not treat ATT&CK relationship context as attribution without corroborating evidence.

Mitigation priorities

  • Map the object to existing controls and identify missing telemetry or response ownership.
  • Prioritize mitigations that reduce exposure on the listed platforms and tactics.
  • Review adjacent ATT&CK relationships before changing policy, detections, or reporting language.
Additional notes and limits

Baseline Glexia take generated from the official MITRE ATT&CK STIX object, source hash, tactics, platforms, and detection fields. It is safe to replace with a richer model-generated take for the same source hash later.

This baseline take is source-grounded and schema-validated, but it does not include environment-specific telemetry, incident evidence, or threat-intelligence corroboration.

Authentication Package

Adversaries may abuse authentication packages to execute DLLs when the system boots. Windows authentication package DLLs are loaded by the Local Security Authority (LSA) process at system start. They provide support for multiple logon processes and multiple security protocols to the operating system.[1]

M1025: Privileged Process Integrity

Privileged Process Integrity focuses on defending highly privileged processes (e.g., system services, antivirus, or authentication processes) from tampering, injection, or compromise by adversaries. These processes often interact with critical components, making them prime targets for techniques like code injection, privilege escalation, and process manipulation. This mitigation can be implemented through the following measures:

Protected Process Mechanisms:

- Enable RunAsPPL on Windows systems to protect LSASS and other critical processes. - Use registry modifications to enforce protected process settings: `HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\RunAsPPL`

Anti-Injection and Memory Protection:

- Enable Control Flow Guard (CFG), DEP, and ASLR to protect against process memory tampering. - Deploy endpoint protection tools that actively block process injection attempts.

Code Signing Validation:

- Implement policies for Windows Defender Application Control (WDAC) or AppLocker to enforce execution of signed binaries. - Ensure critical processes are signed with valid certificates.

Access Controls:

- Use DACLs and MIC to limit which users and processes can interact with privileged processes. - Disable unnecessary debugging capabilities for high-privileged processes.

Kernel-Level Protections:

- Ensure Kernel Patch Protection (PatchGuard) is enabled on Windows systems. - Leverage SELinux or AppArmor on Linux to enforce kernel-level security policies.

*Tools for Implementation*

Protected Process Light (PPL):

- RunAsPPL (Windows) - Windows Defender Credential Guard

Code Integrity and Signing:

- Windows Defender Application Control (WDAC) - AppLocker - SELinux/AppArmor (Linux)

Memory Protection:

- Control Flow Guard (CFG), Data Execution Prevention (DEP), ASLR

Process Isolation/Sandboxing:

- Firejail (Linux Sandbox) - Windows Sandbox - QEMU/KVM-based isolation

Kernel Protection:

- PatchGuard (Windows Kernel Patch Protection) - SELinux (Mandatory Access Control for Linux) - AppArmor
