Forensic Retrieval of Historical DNS TXT Records (SPF, DKIM, DMARC)
Budget: ₹1,500 – ₹12,500 INR
I am seeking an experienced DNS/Email security researcher to retrieve forensic-style historical DNS TXT records (SPF, DKIM, DMARC) for the domain alameda-research.com, covering the period from 1 Jan 2021 to 31 Dec 2022.
Key Objectives:
- Confirm DMARC policies used during this timeframe.
- Identify DKIM selectors and their values (if available).
- Retrieve SPF records and document changes over time.
Deliverables:
1. A CSV or Excel file containing:
- `record_type`, `txt_value`, `first_seen`, `last_seen`, `data_source`.
2. Supporting screenshots or raw query logs from passive DNS datasets for verification purposes.
3. A methodology note describing the tools/datasets used (e.g., DomainTools, Farsight DNSDB, RiskIQ).
4. A short forensic-style report summarizing SPF, DKIM, and DMARC adoption during 2021–22. The report should be written in a forensic investigation style, with clear timestamps and supporting evidence, as the output may be used in a legal/forensic context.
Important Note: I am only looking for bids from experienced DNS/email security researchers with real access to passive DNS datasets such as DomainTools, Farsight DNSDB, or RiskIQ PassiveTotal. Generic or inexperienced freelancers will not be considered.
Ideal Skills and Experience:
- Expertise in DNS/Email security research and passive DNS analysis.
- Access to paid passive DNS datasets such as DomainTools, Farsight DNSDB, or RiskIQ PassiveTotal.
- Ability to deliver accurate results within a tight timeline.
Timeline: Within 5–7 days.
Budget: $50 – $120 USD (depending on depth and quality of data).
Only experienced DNS/email security researchers with proven access to passive DNS datasets (DomainTools, Farsight DNSDB, RiskIQ, etc.) should bid. Beginners or generic freelancers will not be considered.
