Last week was all about phishing, vishing, and spoofing attacks that kept the experts on their toes. While GPS spoofing attacks saw a sudden spike due to regional conflicts between the US and Iran, the ad tech brand Optimizely was targeted by a group of threat actors. Also, cybercrooks have been trying to exploit users…
A DMARC lookup helps you troubleshoot suspected email spoofing or phishing by verifying a domain’s DMARC/SPF/DKIM DNS records, interpreting policy and alignment settings, and correlating DMARC aggregate/forensic reports with messageheaders to identify the true source, delivery path, and exact configuration gaps to fix. DMARC (Domain-based Message Authentication, Reporting, and Conformance) works by aligning a message’s…
Phishing is no longer just a nuisance—it has evolved into one of the most persistent and damaging cybersecurity threats facing organizations today. At DMARCReport, we continuously analyze global email traffic, authentication patterns, and attack vectors to understand how phishing is evolving and what organizations must do to stay protected. What the data shows is clear:…
Receivers most often fail to recognize a DMARC DNS record because of syntax or tag-value errors (for example, missing v=DMARC1 or invalid p=), wrong DNS type or placement (DMARC must be a TXT at _dmarc.yourdomain), provider UI formatting or TXT-length mishandling, propagation/TTL and negative caching, DNSSEC or delegation problems, invalid or unverified rua/ruf URIs, duplicate/conflicting…
To read DMARC XML aggregate reports and detect unauthorized senders, you must parse and normalize the RUA schema fields (policy_published, record/row/identifiers/auth_results), correlate SPF/DKIM results with domain alignment and known infrastructure, apply volume/fail-rate/IP-diversity heuristics enriched with DNS/WHOIS/ASN/threat intel, and alert on suspicious patterns while suppressing forwarding artifacts—an end‑to‑end workflow that DMARCReport automates and scales. DMARC aggregate…
Last week was all about the big names that got targeted by threat actors. The attacks look a bit more sophisticated. For instance, cybercrooks have been abusing Google Account security pages to gain access to sensitive data, such as passcodes. Qatar Airways suggests that agents use verified platforms. Australia-based LinkedIn accounts are being easily targeted…
A DMARC check matters more than ever because, unlike SPF and DKIM alone, DMARC enforces domain alignment and receiver-enforceable policy (quarantine/reject) with rich reporting that prevents spoofing at scale, restores sender visibility, and measurably improves security and deliverability across complex email ecosystems. Email authentication matured from “can the sender prove they own the IP/key?” (SPF/DKIM)…
In today’s digital world, email remains one of the most widely used communication channels for businesses and individuals alike. From important system alerts to marketing newsletters, email drives essential communication. But this critical channel also attracts malicious actors — and without proper protections in place, your domain can become an easy target for phishing, spoofing,…
To stop guessing your DMARC data, configure a free analyzer like DMARCReport with correct RUA/RUF endpoints, tune reporting scope (aggregate vs. forensic), normalize noisy sources, interpret pass/fail and alignment metrics, and roll out policy changes incrementally (none → quarantine → reject) with alerting, automation, and privacy controls. Email authentication only works when you can see…
Protecting your email infrastructure doesn’t just mean implementing a few basic authentication protocols. It’s 2026, and email service providers no longer evaluate these protocols in isolation. They understand that spoofing and phishing have become intrinsic to today’s cyber threat landscape, and that these threats are evolving just as fast as legitimate email ecosystems. Attackers are…
A DMARC record stops phishing and domain abuse by instructing receiving mail servers to reject or quarantine any message that fails SPF or DKIM alignment with your domain and by sending you actionable reports that identify unauthorized sending sources. DMARC (Domain-based Message Authentication, Reporting & Conformance) builds on SPF and DKIM to authenticate who can…
In today’s digital world, almost everything we access online has a web address — a URL (Uniform Resource Locator). These seemingly ordinary strings of text are the doorways to websites, files, apps, cloud dashboards, support pages, videos, and more. But what many people don’t realize is that those URLs can be manipulated — sometimes for…
A DMARC generator helps you discover and fix SPF issues (excessive DNS lookups, bad include chains, missing ip4/ip6 ranges, syntax errors), DKIM problems (missing/invalid signatures, wrong selector, weak keys, canonicalization mismatches, domain misalignment), DMARC record mistakes (multiple records, malformed tags, wrong p/pct, incorrect or unauthorized rua/ruf URIs), third‑party sender alignment gaps (marketing/CRM/cloud platforms not aligned…
