The stronger and better DMARC2.0 is almost here. This upgraded, tighter version aims to combat the growing menace of email-based phishing and spoofing attacks, especially the ones powered by artificial intelligence.
Email communication remains one of the most essential tools for businesses and individuals alike, but ensuring its authenticity is critical to protecting recipients from phishing and spoofing attacks. One of the key mechanisms for verifying the legitimacy of an email is DomainKeys Identified Mail (DKIM), which uses cryptographic signatures to confirm that messages haven’t been altered in transit and truly originate from the claimed domain.
The finance sector thrives on trust. The fact that your clients are putting their hard-earned money in your company or institution shows that they not only have confidence in your financial products or services, but also that they believe you have the ability to keep their assets and data safe. But, truth be told, their money and data aren’t really safe unless you actively protect them.
Email security has become a critical priority for businesses and organizations of all sizes, and DMARC (Domain-based Message Authentication, Reporting, and Conformance) plays a central role in protecting domains from spoofing and phishing attacks. While setting up DMARC ensures that unauthorized messages are flagged or rejected, the real challenge lies in understanding the flood of DMARC XML reports that email providers generate. These reports contain valuable insights into who is sending emails on your behalf, whether they pass authentication checks, and where potential vulnerabilities may exist.
Email remains one of the most vital communication tools for both businesses and individuals, but when outgoing messages fail to send, productivity and reliability take a hit. At the heart of email delivery lies the Simple Mail Transfer Protocol (SMTP) server, which is responsible for relaying messages from your email client to the recipient’s inbox. However, misconfigurations, connectivity problems, or security restrictions can cause SMTP servers to malfunction, leaving users frustrated with undelivered or bounced emails.

Cybersecurity incidents this week include Google completing notifications for a Salesforce breach linked to ShinyHunters, and the discovery of Charon ransomware targeting the Middle East public and aviation sectors with APT-style tactics. Researchers exposed new 2TETRA:2BURST flaws in critical TETRA radio systems, while a WinRAR zero-day was exploited by Paper Werewolf and RomCom groups. The GreedyBear campaign stole over $1 million via malicious browser extensions, alongside an Ethereum trading bot scam using AI-generated YouTube videos to drain wallets of nearly $900,000. Let’s dissect each news in brief!
In today’s digital landscape, email security is more critical than ever. Cybercriminals frequently exploit email systems through spoofing and phishing, making it essential for organizations to adopt robust authentication methods. DomainKeys Identified Mail (DKIM) is one of the core email authentication protocols that helps verify a sender’s identity and ensures that messages are not altered in transit. Implementing DKIM involves publishing a TXT record in your domain’s DNS, which serves as a digital signature for outgoing emails.
It is a common practice for businesses to delegate marketing tasks to third-party agencies. Working with these marketing agencies brings in added benefits such as specialisation in particular niches and cost-effectiveness. These agencies need to take extra care to ensure their emails don’t end up in the spam folder or get rejected.
DMARC has now become a non-negotiable for every organization that sends bulk emails on a daily basis. It is even more critical for banks, where the stakes are so high that it’s not merely about money, but also sensitive data of their customers, regulatory compliance, and the integrity of their brand.

Sometimes your email just doesn’t reach its recipient. You’ve done everything right— crafted the perfect message, sent it to the correct address, and even authenticated your domain with email authentication protocols. Yet, it gets flagged or doesn’t even land in the receiver’s mailbox.
SPF macros can be best described as placeholders that are used within SPF records. They intend to make the SPF record more flexible and intelligent. This way, you don’t have to hardcode every detail; you can use macros like %{i}, %{d}, and %{h} to allow SPF records to adapt during a live email authentication check.

From arrests slowing down major hacker groups to new threats quickly taking their place, this week has been full of movement in the cybersecurity space. Threat actors are shifting tactics, launching new ransomware groups, targeting telecoms, and using fake mobile apps to steal and extort. Even major airlines and telecom giants like Aeroflot and Orange haven’t been spared. Here’s a roundup of the key cyber incidents and developments of the week.
In an age where our inboxes are overflowing with messages, ensuring that the emails you send actually reach their intended recipients can feel like a daunting task. Have you ever wondered why some of your important emails end up lost in the void of the spam folder or, worse, get rejected outright? This is often due to a little-known defense mechanism called the Sender Policy Framework (SPF).
If you are planning to secure your business email communications by deploying email authentication policies such as SPF, DKIM, and DMARC, know that this is just the tip of the iceberg. In order to ensure fool-proof security for your email landscape, you must use a DMARC analyzer tool. With its help, you get to evaluate DMARC reports closely, thereby bolstering the email system.
In a world where email communication is essential for businesses, it’s alarming how many organizations overlook the basics of email security. Have you ever received an email from a seemingly trustworthy source, only to later discover it was a clever spoof? This common issue highlights the importance of establishing a solid foundation for your email systems.
In today’s tech-driven world, the threat of zero-day attacks looms larger than ever. These types of cyber threats catch many organizations off guard, often exploiting vulnerabilities before anyone knows they exist. Imagine a thief sneaking into your home through a door you didn’t even know was unlocked—that’s the reality for many businesses facing these hidden dangers.
