We’ve all been there— forgotten passwords, set ones that were too simple to be hacked, or used the same passwords across all accounts. But ideally, your priority should be security, not convenience.

We’re back with the week’s cybersecurity round-up of a mix of high-stakes breaches, targeted malware campaigns, and growing concerns around supply chain vulnerabilities. Each of these incidents highlights different tactics attackers are using to exploit trust, access, and visibility. Read on for all the details.
Email is a cornerstone of communication, but imagine sending a message that never arrives or worse, ends up in someone’s spam folder. Frustrating, right? That’s where SPF records come into play. They help email servers decide whether the emails they receive are from someone who’s actually allowed to send them. You might think creating an SPF record sounds complicated, but it’s simpler than you might expect. It’s all about making sure the right people can send messages on your behalf while keeping the unwanted ones at bay. This guide will walk you through setting up your own SPF record step by step, ensuring your emails get where they need to go—without any hiccups along the way!
Attackers often outsmart the cybersecurity custodians, and a DKIM replay attack is one such technique exploited by them to sign, seal, and send fraudulent emails using a valid DKIM signature.
Understanding SPF Records for Email Security Have you ever wondered why some of your emails vanish into spam folders while others land right in the inbox? The secret often lies in something called the SPF record. Think of it as a digital passport for your emails, showing the world which servers are allowed to send messages for your domain. Properly managing this little-known aspect can save you from headaches and ensure that your emails are delivered with confidence.

This week in cybersecurity–a student admits to a massive school data hack, a major mobile network outage turns out to be a cyberattack, and hackers are actively spying on global aid operations. We also look into a DNS hijacking campaign affecting top organizations, and a trusted VMware tool gets caught in a malware-laced supply chain attack. Here’s a quick look at what’s been happening.
Email is a vital part of our everyday communication, especially for businesses. But did you know that without proper safeguards, your emails could be at risk of being spoofed by cybercriminals? That’s where SPF records come in. Setting up an SPF (Sender Policy Framework) record gives your domain the protection it needs against email impersonation, ensuring that only trusted servers can send emails on your behalf.
It’s well known that you need to have a strong defence mechanism in place to ward off phishing attacks. Speaking of which, Domain-based Message Authentication, Reporting, and Conformance (DMARC) stands out as an email security protocol. Not only does it protect your domain from being misused by attackers, but it also gives you control over how unauthenticated emails are handled.
In the digital age, ensuring that your emails reach their intended recipients without getting lost in the spam folder is crucial. Just think about how frustrating it can be when you send an important message, only to find out later that it was never received. An effective way to enhance your email deliverability and security is by using a Sender Policy Framework (SPF) record. But what exactly does that mean? Simply put, an SPF record tells email servers which senders are allowed to send emails on behalf of your domain. Crafting these records might seem daunting, but with the right tools, you can quickly create a solid SPF configuration. In this article, we’ll explore some of the best SPF record generators available and how they can simplify this vital task for you.
