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.
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.
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.
When you check your email, how often do you stop to think about the risks lurking behind seemingly innocent messages? Spear phishing attacks—targeted attempts designed to trick individuals into revealing sensitive information—are becoming more common and far more sophisticated. As cybercriminals zero in on their targets with personalized tactics, it’s essential for everyone, especially employees, to recognize these threats before they strike.

Attackers are getting creative again, using copy-paste tricks to drop malware, hiding Android threats inside broken app files, and setting up entire fake startups to steal crypto. Developers are being targeted through tampered npm packages, while a newly exposed Wing FTP flaw is already under active abuse. With techniques evolving fast, staying patched and alert is more important than ever. Read on to stay a step ahead!
Starting July 3, 2025, Cloudflare requires all emails to be authenticated using at least one of the protocols. SPF or DKIM, to forward them. This requirement has been imposed in consideration of the growing number of email-based phishing and spoofing attacks. These email authentication protocols ensure that only authorized emails reach the inboxes of recipients, thereby preventing them from being manipulated into transferring money or sharing confidential information.
Email communication has become a vital part of our daily lives, especially for businesses. But did you know that a simple yet crucial security feature can help protect your emails from being tampered with or falsely represented? That’s where DKIM (DomainKeys Identified Mail) comes in. This method adds a digital signature to your email, giving both you and your recipients peace of mind that messages are authentic and safe.
If you are struggling with disappearing emails or deliverability drops when targeting Microsoft 365 users, then it’s an indication of an underlying issue— misconfigured or missing email authentication protocols.
