Understanding the concept of fallback mechanisms in Sender Policy Framework
Understanding the concept of fallback mechanisms in Sender Policy Framework
Sometimes, when an email doesn’t pass the SPF authentication checks, the receiving server or policies offer better ways to handle or mitigate the failure. This is done using fallback mechanisms— a way to secure email communication without hampering the flow and productivity. (more…)
Yahoo Japan has mandated DMARC and domain authentication
Yahoo Japan has mandated DMARC and domain authentication
In November 2023, Yahoo announced that by February 1st, 2024, any company that sends more than 5,000 emails per day has to deploy DMARC to minimize the risk of email-based spoofing, phishing, and ransomware. After this announcement, the rate of DMARC adoption surged, and now Yahoo Japan has also made DMARC and domain authentication mandatory for users as of December 2024. Experts see this as a great opportunity to improve companies’ email security posture. (more…)
Is your DMARC enforcement strict enough?
Is your DMARC enforcement strict enough?
Back in 2024, email service providers such as Google and Yahoo rolled out new email-sending policies. One would have thought that organizations would begin to take email security more seriously, but so far, that hasn’t been the case. In fact, cybersecurity experts have found that phishing attacks have shot up, with the number of phishing messages increasing by 202% in the second half of 2024.

New PhishWP Threat, Illicit Marketplace Live, Codefinger Targets AWS – Cybersecurity News [January 13, 2025]
Cybercriminals are enhancing their capabilities, as evidenced by the latest PhishPWP phishing threat. Similarly, this week’s cybersecurity bulletin highlights the latest ransomware attack on AWS servers, making recovery impossible without the attacker’s key. We also look at how cybercriminals use popular social media channels like Telegram. Zero-day attacks are the most dangerous of all, as they emerge from practically nowhere. This week’s news highlights one such attack on Fortinet FortiGate firewall users. Finally, we round off a reputed university shutting off classes, fearing a cyber-attack on its network.

Implementing DKIM the right way: A guide for ESPs
You might have heard that email authentication protocols are only for businesses, but that’s not entirely true!
Don’t you think email security is crucial for everyone, including businesses that send email campaigns and email service providers (ESPs) that facilitate them? If so, you can agree with us when we say that email authentication is a must for every entity in the email ecosystem, including the ESPs.

Just like SPF offers domain owners the choice between Softfail and Hardfail, DMARC has three enforcement rules: none, quarantine, and reject. Each has its own significance and relevance in the DMARC compliance journey.

Ensuring proper cybersecurity is at the top of every organization’s agenda this year. That explains why Microsoft cautions its Windows 10 users and asks them to upgrade their PC’s OS before the 14 October 2025 deadline. However, even the most robust cybersecurity strategies might seem inadequate, especially as three more telecoms become victims of the Salt Typhoon.

Understanding everything about DMARC records and tags
Email security is a growing concern for businesses and individuals alike. Increased email spoofing and phishing attempts have made it crucial to implement security measures to safeguard communication channels. One such powerful tool to protect email communications is DMARC or Domain-based Message Authentication Reporting and Conformance. Its job is to authenticate email messages and take suitable action against unauthorized emails. The DMARC policy works in coordination with SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail) protocols.

What is Apple Business Mail and how can you set it up using Apple Business Connect
Apple Mail is not very prominently used in business emails because, unlike Gmail, Yahoo, and other mailboxes, it doesn’t support BIMI. However, Apple has taken the initiative to resolve this issue. With the latest iOS 18.2 update, Apple is now letting its users send branded emails that carry their unique identity. In simple words, you can send emails that show your brand logo and name, just like BIMI. This is done to build trust among companies regarding email authentication.

The New Year is the time for resolutions. Individuals and organizations must focus on cybersecurity and resolve to take proactive steps to prevent cybercrime. Data breaches have become increasingly frequent. With people increasingly using smartphones to access the internet, securing these instruments should be paramount. In the face of rising cyber threats, ensuring robust email security on your devices, such as conducting security checks on Android and iPhones, is a vital step to safeguarding your personal and organizational data from breaches and attacks.
The ultimate DMARC monitoring guide you need to keep your domain safe
The ultimate DMARC monitoring guide you need to keep your domain safe
The emails you send out to your clients have the potential to transform your business. Although you might already know this, what you might not be aware of is that not all your emails reach your recipients’ inboxes. Instead of landing in the inbox where the recipient can read and engage with the email, some emails might get flagged as spam or, worse, fail to deliver altogether. There are many reasons this could happen, but the most common reasons that Email Service Providers (ESPs) flag your emails are improper authentication, suspicious activities, or malicious actors attempting to spoof your domain. These are some of the last things you would want for your emails.

Cybercriminals are intelligent and innovative, proactively searching for notorious ideas to launch their cyberattacks. This week’s news article discusses two innovative methods that threat actors consider, the crypto-romance scammers and the digital arrest scam. Nowadays cyber attackers are willing to target almost anything, we will learn about the two attacks that targeted on an online doughnut chain and an auto parts company. Hence, efforts are being made on grounds of user awareness and system updates that should help prevent such attacks. But downloading and installing updates can also be confusing so we have also discussed whether to download the latest Microsoft system update or not. Read on to learn more.

Here’s a reality check— your email ecosystem is not secure enough!
Scammers are everywhere, prying on your outgoing emails, trying to intercept them, and convincing your clients that those emails are genuinely from you—a classic tactic that threat actors use to carry out their malicious scams. Lately, these techniques have become more sophisticated and common.

Zero-day vulnerabilities are the most critical because no one knows about them unless they are discovered. Therefore, malicious actors have greater chances of exploiting them before corrective measures are initiated. In this week’s news section, we shall discuss some zero-day vulnerabilities and the measures software producers take to mitigate the risks.

You probably already know that your logo is one of the biggest assets your brand owns, but wouldn’t it be great if it showed next to your emails in the inboxes of your recipients? The way to make that happen is BIMI, which stands for Brand Indicators for Message Identification. BIMI lets your logo show up next to your emails when they land in the recipient’s mailbox, which will help your brand stand out and build trust with your audience.
Building a zero-trust security model for emails
Building a zero-trust security model for emails
According to Verizon’s 2023 Data Breach Investigations Report, somewhere between 75% and 91% of targeted cyberattacks start with an email. Considering that such statistics surface in the news every day, organizations are trying to keep up with the growing number of sophisticated cyberattacks. Email is one of the most exploited vectors for phishing and ransomware attacks. Traditional security measures and technologies are evidently failing to ward off new-age cyberattacks; that’s why the latest solutions, like zero-trust security models, are emerging as robust alternatives.
Basics of DKIM syntax and tags
Basics of DKIM syntax and tags
DKIM stands for DomainKeys Identified Mail, a cryptography-based email authentication protocol that helps receiving servers verify if an email sent from your domain was tampered with in transit. If you have DKIM deployed for your domain, then your server will affix a digital signature to the header with each outgoing email. This is a cryptographically secured signature that is produced using a private key that is known only to you. The counterpart of the private key is a public key, which is published in the DNS of your domain.
