🔍 Detection Method
===================
🛠️ Tool
Opening: LOLBASline is a PowerShell module designed to baseline Windows endpoints for Living Off The Land Binaries and Scripts (LOLBAS). The tool enumerates entries from the official LOLBAS YAML dataset, verifies binary presence, and attempts representative command executions to assess whether those binaries can be used for agentless or fileless TTPs.
Key Features:
• Repository handling: Auto-clones the LOLBAS project when no local path is supplied, parsing YAML definitions for metadata and execution examples.
• Presence verification: Confirms file system presence and common install paths for listed binaries and scripts.
• Execution capability tests: Attempts safe, representative commands configured in the YAML to validate whether an observable execution path exists.
• Reporting: Produces a structured CSV containing detected items, execution success/failure, timestamps, and YAML-sourced metadata for downstream analysis.
Use Cases:
• Rapid endpoint assessment in lab and red-team environments to enumerate potential living-off-the-land opportunities.
• Creating an inventory of allowed vs. risky binaries for defensive teams and baselining for detection tuning.
Strengths & Considerations:
• Strengths include automation of YAML parsing, consolidated reporting, and an explicit focus on execution capability rather than mere presence.
• Considerations include operational risk: the execution tests are intentionally active and may trigger EDR, SIEM alerts, or unintended side effects. The README warns explicitly against running on production systems.
Detection & Defensive Value:
• Output CSV can be ingested into asset databases or SIEMs to correlate detected LOLBAS items with telemetry and to prioritize detection rules for high-risk executables.
Limitations:
• The tool relies on YAML examples that may not cover all execution vectors or contextual privilege constraints; a successful representative command does not prove full exploitability in all contexts.
• False positives/negatives are possible depending on path variations, aliasing, and environment-specific restrictions.
