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.
This week’s cybersecurity roundup brings a mix of arrests, warnings, and active threats. Intel chips face a newly discovered vulnerability affecting years of hardware.

Cybersecurity in the age of AI: How innovation is empowering both defenders and attackers
by DuoCircle
The cyber threat landscape has always been complex and evolving, but the advent of AI has empowered threat actors to bypass security filters more easily than ever. They are now penetrating deep into every sector, affecting interconnected operations at multiple levels. AI-backed deception has led to a stage where now a staggering 87% of global organizations have faced an AI-powered cyberattack in the past year.
Setting up an SMTP relay on a Windows Server might sound like a daunting task, but it’s essential for keeping your email communications flowing smoothly. If you’ve ever hit “send” on an email and wondered what happens next, you’re not alone. Email messages travel across multiple servers before reaching their destination, making proper configuration crucial for success. Understanding the basics of how SMTP relay works can save you from frustrating delays and delivery issues down the line. This guide will take you step-by-step through the setup process, ensuring that your emails are sent securely and efficiently while navigating the unique features of newer Windows Server versions like 2025. So, let’s dive in and simplify this process together!
This week, attackers found a clever way to slip ransomware past SentinelOne’s defenses using its own update process. A serious Apache Parquet flaw just got easier to exploit thanks to a new public tool. The U.S. government is warning energy sector operators about ongoing cyber threats that use alarmingly basic tactics, and medical tech enterprise Masimo is dealing with production delays after a network breach. Plus, the Darcula phishing service is abusing iMessage and RCS. Full breakdowns below!
Are humans the most vulnerable link when it comes to cybersecurity?
by DuoCircle
The cybersecurity ecosystem stands tall on three supporting pillars- technology, processes, and people. As cyber scams are getting more sophisticated with one attack at a time, cybersecurity experts are bound to introduce more complex technology and intricate processes to curb the risk. However, human beings tend to lag behind when it comes to matching the pace with the latest cybersecurity dynamics. The 2025 Data Breach Investigation Report by Verizon has claimed that a staggering 60% of data breaches took place because of human error. Undeniably, we are the most vulnerable when it comes to the cybersecurity landscape.
Email response management software helps your team handle messages more efficiently, reducing missed opportunities and improving customer satisfaction. These tools organize conversations, automate routine responses, and track performance metrics.
Phishers abuse Google sites and DKIM replay to send fake emails and steal credentials
by DuoCircle
In a highly sophisticated phishing attack, cybercriminals took an uncommon path to allow fraudulent phishing emails to bypass Google’s security filters and redirect recipients to cloned websites, where they were asked to enter their credentials. The emails were sent from no-reply@google.com and included valid DKIM signatures— in short, it was a classic case of DKIM replay attack. That’s why they passed email authentication checks and Gmail displayed them without any warnings.
This week’s updates are packed with real-time threats and adversarial attacks. Nowadays, even Apple devices are open to silent attacks without users even tapping a button. A few software flaws are now confirmed to be under real attack, and there’s a fresh warning about ransomware-as-a-service being marketed with brand-friendly options. And if your developers forget to hide Git files, there’s a growing number of attackers ready to pounce. Here’s what happened recently and what details you should know of.
