L00 — Paper Trail
BRIEFING
specter0@a516e51a9bc0:~$ cat BRIEFING
MISSION: Paper Trail
====================
You are on contract to assess target-corp.local. Pre-engagement
recon only — NO active scanning of the target yet. Your job is
purely passive / OSINT-style intelligence gathering against
public-facing data the target has let slip.
Collect 8 distinct intel items AND declare which independent
sources you used to corroborate each one. Write them to
/tmp/intel.yaml in the format below, then run
/opt/verify-paper-trail.sh.
YAML fields required:
registrar: <current domain registrar>
registration_date: <original creation date, YYYY-MM-DD>
subdomains: [<two real subdomains>]
email_format: <canonical pattern, e.g. first.last@target-corp.local>
breach_credential:
user: <leaked email>
password: <leaked plaintext>
internal_host: <internal FQDN leaked publicly>
s3_bucket: <staging bucket discovered via CT>
cloud_provider: <primary IaaS provider>
sources: # which families backed each finding
registrar: [<family-1>, <family-2>]
registration_date: [<family-1>] # only one canonical path
subdomains: [<family-1>, <family-2>]
email_format: [<family-1>, <family-2>]
breach_credential: [<family-1>, <family-2>]
internal_host: [<family-1>, <family-2>]
s3_bucket: [<family-1>, <family-2>]
cloud_provider: [<family-1>, <family-2>]
Notes:
- "Source family" = a truly independent data source. Two queries
against the same engine count as ONE family.
- Allowed families: whois-current, whois-archive, hibp-2022,
hibp-2023, hibp-2024, ct-logs, github-mirror, web-recon,
ci-page, dns-direct.
- Submitting a documented decoy (e.g. the post-transfer date the
current WHOIS explicitly disclaims) trips a soft-rejection
canary. Read source notices before trusting their values.
REFERENCE READING (if you get stuck):
- bellingcat.com — open-source investigation methodology
- berkeleyprotocol.org / OHCHR Berkeley Protocol PDF — chain of custody
- osintcurious.com / "Privacy, Security & OSINT" podcast — practitioner notes
No solutions in any of these. Methodology only.
Ephemeral session — no persistent state.
