This is the fourth edition of the month, and we have curated the top three cyber incidents that you must know about. We will begin the bulletin with the alleged threat attack on a French post office. Next, we will discuss the recent cyberattack on Romanian waters and try to understand the extent of damage…
Email security is among the most critical aspects of modern digital communications. Every year, organizations lose money, time, and reputation due to email fraud, phishing attacks, and domain spoofing. Studies show that even small breaches can cost businesses tens of thousands of dollars, while larger enterprises can lose millions per incident. With email-based threats rising…
Start by publishing a DMARC TXT record with aggregate (RUA) and optional forensic (RUF) destinations, ingesting those reports into a parser like DMARCReport, and then reading the aggregate XML fields—policy, alignment, SPF/DKIM results, source IP, and message counts—to correlate failures with your SPF/DKIM/DNS configuration and remediate misconfigurations before gradually tightening policy. DMARC is an authentication…
In today’s digital world, email remains one of the most powerful communication channels, but it is also one of the most abused. Every day, millions of malicious emails are sent to deceive recipients — from phishing to brand spoofing to targeted business email compromise (BEC). As these attacks evolve, so too must our defenses. At…
You should expect initial DMARC-driven delivery effects as soon as DNS caches refresh your new TXT record—typically within 5–60 minutes, broad enforcement by major mailbox providers within 1–24 hours, and full stabilization (including report-based visibility) within 24–72 hours. DMARC is evaluated in real time on each message, but its input—the DMARC TXT record at _dmarc.yourdomain—travels…
The best tools for validating and analyzing a DMARC record example are a combination of web validators (DMARCReport Validator, MXToolbox, dmarcian, DMARC Analyzer), command-line utilities (dig/host/nslookup, OpenDMARC), open-source parsers (parsedmarc), and APIs (DMARCReport API, SecurityTrails, WhoisXML) supplemented by deliverability testbeds (Gmail/Outlook header analysis, Mail-Tester, GlockApps) to cover both syntax accuracy and real-world enforcement outcomes. Why…
In today’s digital ecosystem, email remains one of the most vital communication channels for organizations worldwide. Yet, without strong safeguards in place, email domains can be abused by attackers to send phishing, spoofing, and other fraudulent messages that harm your brand, customers, and internal users. To protect your domain and ensure only authorized email senders…
A DMARC report analyzer reduces phishing and spoofing by transforming raw RUA/RUF data into prioritized insights, automated enforcement, and rapid incident response that block unauthorized senders while preserving legitimate email flows. Email authentication works only when you can see who’s sending on your behalf, how their messages authenticate, and where policy changes will help—or hurt—deliverability;…
DMARC is important for protecting emails sent from G Suite (Google Workspace) because it verifies your domain’s messages via SPF/DKIM alignment and tells receiving servers to quarantine or reject spoofed mail, which dramatically reduces phishing while improving deliverability and visibility through standardized reporting. G Suite’s native security (SPF and DKIM) prevents many spoofing attempts, but…
RUA (DMARC aggregate) reporting is important because it gives domain owners daily, privacy-safe, cross‑receiver visibility into SPF/DKIM authentication and alignment outcomes at scale, so they can detect, prioritize, and remediate email authentication issues and abuse before they impact deliverability, brand, or customers. Email authentication only works if you can see where it fails. DMARC’s aggregate…
Gmail rejects or marks your messages as spam when your DMARC policy is strict because the messages fail DMARC alignment (SPF or DKIM pass but don’t align with the visible From domain), alignment is broken by forwarding/lists/intermediaries, or misconfigurations exist, and Gmail combines these results with reputation and engagement signals to quarantine or reject according…
Email platforms today are much stricter about security and trust, and have become far less forgiving than ever. This means even a minor slip-up could cost your brand visibility, credibility, and trust among the email service providers and recipients. Now imagine this happening repeatedly. If your outgoing emails often fail authentication checks, trigger spam complaints,…
Cybercriminals are getting smarter, quieter, and far more convincing. From a new browser-based ClickFix variant that slips past traditional security tools, to healthcare organizations facing legal action after phishing breaches, and even UK MPs being targeted through trusted messaging apps, recent incidents show how fast attack methods are evolving. These threats no longer rely on…
In today’s hyper-connected world, where digital services power everything from your business to your personal communications, the threat landscape continues to evolve at an unprecedented pace. Among the most prevalent and damaging types of cyberattacks are Denial-of-Service (DoS) and Distributed Denial-of-Service (DDoS) attacks. These attacks don’t aim to steal data or quietly infiltrate systems—instead, they…
To check whether your domain’s DMARC policy is correctly configured for Gmail, validate your DMARC DNS TXT record syntax and tags, confirm SPF and DKIM alignment with your header-from domain, send test messages to Gmail and inspect Authentication-Results and Google Postmaster Tools, verify delivery and parsing of DMARC aggregate (rua) reports (noting Gmail does not…
In today’s hyper-connected digital world, email remains the backbone of business communication — and unfortunately, also one of the most exploited attack vectors used by cybercriminals. Sophisticated threat actors continually refine their techniques to deceive trusted recipients, impersonate legitimate senders, and manipulate end users into disclosing sensitive information or transferring funds. At DMARCReport, we believe…
