ReconnaissanceTactic: Discovery (TA0007)6 Verified Binaries

Reconnaissance LOLBins & Internal Host Discovery

Adversaries abuse built-in command line tools to enumerate local users, domain trust relationships, network shares, installed software, and security configurations prior to lateral movement.

Detection Engineering Context

Adversaries chain commands like whoami, net.exe, ipconfig, and systeminfo during post-exploitation triage to orient themselves inside target networks.

Key Log Telemetry: Bursts of native discovery process creation events within short timeframes (high process command count in < 60 seconds).
Total Capable Binaries: 6
Windows: 3
Linux: 0
macOS: 3
