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).
What is a DMARC analyzer tool, and how to use it in the best way?

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.
The 32KB limit in DMARC reports: What it means and why it matters

Has it ever happened to you that you sent around 500,000 emails a day but only received DMARC reports for half of them? That too, without any alerts or warnings?
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.
From malware sneaking in through fake game cheats to ransomware hitting hospitals, this week’s cyber stories are anything but quiet. Lumma’s back in action, Coyote’s abusing Windows in clever ways, and even Dior couldn’t dodge a data breach. If you use the internet (and who doesn’t?), here’s what you should be paying attention to.
How to fix the “DMARC policy not enabled” error- Everything you need to know!
by DuoCircle
If you have stumbled upon this blog, then it is highly likely that you are dealing with the issue of the “DMARC policy not enabled” error. You get this message when your domain has a DMARC record, but there is no valid policy to define it. A DMARC record makes no sense without a DMARC policy. It’s like having a front desk guard in your building who smiles and nods, even when strangers walk in. Hence, the moment this message appears, you must understand that your email system is no longer protected against phishing and spoofing attacks.
In a world where emails are the primary means of communication, the risk of phishing attacks lurks just one click away. Whether it’s a seemingly innocuous message from a “trusted” source or a polished-looking request for sensitive information, these scams can catch anyone off guard. The reality is that identifying these threats isn’t just about having the latest technology; it also relies heavily on being informed and proactive.
How are Gmail and Outlook policies raising the bar for DMARC adoption?

There was a time when email security was a mere IT concern; it was a good-to-have but wasn’t really a priority. We are referring to a time when email-based threats were not as prevalent or dangerous as they are today. It might sound like we are talking about a distant past here, but that’s the reality. You can no longer put email security on the back burner, thinking that your emails will protect themselves or that cybercriminals will never reach you.
