Setting up a robust and reliable Windows email server can feel like deciphering an ancient scroll written by Roy Fielding himself — packed with cryptic protocols and obscure configurations. Yet, with the right guidance, configuring these servers transitions from hair-pulling chaos to an empowering exercise in email mastery.
![Ransomware Hits Hybrid, Data Theft Campaigns, Phishing Targets Companies – Cybersecurity News [August 25, 2025]](https://www.duocircle.com/wp-content/uploads/2025/09/dmarc-reporting-service-3456.jpg)
Cybersecurity threats are on the rise again this week. Hybrid cloud ransomware attacks are becoming more and more frequent. Intruders are now stealing vast amounts of data and wiping out backups without even using traditional malware. Also, government networks in Asia have been targeted in long-running data theft campaigns. On top of all that, a global wave of phishing is hitting people with new malware delivered through fake voicemails and purchase orders. In South Asia, some skilled attackers are expanding their threat space to target Linux systems. And if that’s not enough, a massive healthcare data breach has exposed the personal details of more than 600,000 individuals.
If you’ve ever dealt with email security, chances are you’ve heard of DMARC—short for Domain-based Message Authentication, Reporting & Conformance. But what exactly does it do, and why should you care? Well, imagine your email domain is your digital storefront, bustling with clients and sensitive communications. Without proper email authentication, it’s like leaving your front door wide open to spoofers and phishers who can impersonate your brand, wreak havoc, and tank your email domain reputation.
Migrating to Office 365, or Microsoft 365 as it’s increasingly known, can feel like preparing for a grand adventure through the digital wilderness. You’re trading your familiar desktop-land for the vast expanse of cloud computing — a brave, sometimes bumpy journey.
DMARC alignment is the final checkpoint that ensures SPF and DKIM are not present for the sake of it, but are actually configured correctly and linked to your sending domain. This is done by verifying that the domain in the email’s visible ‘From’ address matches (or is aligned with) the domains used in SPF and/or DKIM authentication.
Email security is one of the most critical aspects of running a professional and trustworthy business. With cyber threats, phishing attempts, and email spoofing on the rise, ensuring that your organization’s emails are authenticated has never been more important. DomainKeys Identified Mail (DKIM) is a widely used email authentication method that adds a digital signature to your outgoing messages, helping prevent tampering and proving that emails truly come from your domain.
The real estate industry has evolved to be as digitally driven as any other industry, like finance and retail. From property listings to deal closures, everything happens online. Although it has made things a lot easier for the agent, seller, and buyer, this digital shift has also opened doors to cyberattackers.
![Apple Patches ImageIO, Hackers Exploit Apache, Noodlophile Targets Firms – Cybersecurity News [August 18, 2025]](https://www.duocircle.com/wp-content/uploads/2025/08/What-is-a-dmarc-5601.jpg)
Cybersecurity threats continue to escalate this week. Apple issued its seventh zero-day fix of 2025 after reports of active exploitation. Hackers are abusing a two-year-old Apache flaw to install hidden back doors that patch themselves to evade detection. A phishing campaign is spreading malware against enterprises worldwide. Authorities renewed sanctions on crypto exchanges that moved over $100 million for ransomware groups and froze another $300 million tied to fraud. At the same time, another malware is exploiting Windows flaws to infiltrate multiple industries.
The stronger and better DMARC2.0 is almost here. This upgraded, tighter version aims to combat the growing menace of email-based phishing and spoofing attacks, especially the ones powered by artificial intelligence.
Email communication remains one of the most essential tools for businesses and individuals alike, but ensuring its authenticity is critical to protecting recipients from phishing and spoofing attacks. One of the key mechanisms for verifying the legitimacy of an email is DomainKeys Identified Mail (DKIM), which uses cryptographic signatures to confirm that messages haven’t been altered in transit and truly originate from the claimed domain.
