Summary

Adds an auditd EXECVE dataset capturing the behavior of an automated Linux enumeration script (LinEnum) on an authorized lab host.

This is the paired attack data for the Linux Auditd Enumeration Script Activity detection submitted to splunk/security_content (behavioral/threshold analytic for enumeration-script fan-out, mapping to T1082/T1083/T1057/T1518).

Details

  • Path: datasets/attack_techniques/T1082/linux_auditd_enumeration/linux_auditd_enumeration.log
  • Format: interpreted auditd EXECVE records (ausearch -i style), source=auditd, sourcetype=auditd, consistent with existing linux_auditd_* datasets.
  • ~95 execve events in a single ~20s window, crossing the detection thresholds (exec>=50, distinct binaries>=15, distinct recon tools>=8): whoami, id, uname, hostname, find, getcap, crontab, sudo, ss, ip, ps, dpkg, lastlog, env, systemctl and more.
  • Committed via git-lfs per the repo .gitattributes (datasets/**/*.log).

EXECVE auditd dataset captured from a real LinEnum run on an authorized
lab host, for the Linux Auditd Enumeration Script Activity detection in
security_content. ~95 execve events in one window crossing the analytic
thresholds (exec>=50, distinct>=15, distinct recon tools>=8).
