Amidst the chaos in the cybersecurity landscape, a new type of cyberattack has been surfacing: BreakSPF. This latest attack framework bypasses the SPF authentication checks, invading target recipients’ inboxes with phishing and spoofing emails. This foul technique is capable of wreaking havoc on a large scale, jeopardizing the security of millions of domains across the world.

The wait is over! We’re here with this week’s round-up of the most pressing cybersecurity events and developments worldwide. The latest reports shed light on a significant data breach at a fintech giant, Finastra, efforts by the USDA to thwart phishing attacks with advanced authentication measures, a zero-day vulnerability impacting PAN-OS devices, VMware vCenter Server flaws being exploited post-patch, and a critical WordPress plugin vulnerability that puts millions of websites at risk.
With rapid digitization, email has become one of the most effective communication tools, both for business and corporate entities. However, the matter of concern is that the same emails are a favorite avenue for threat actors who exploit them to carry out malicious attacks, impersonate trusted brands, and spam naive users. This is where DMARC (Domain-based Message Authentication, Reporting, and Conformance) steps in! This is a robust email authentication protocol that can protect your domain as well as email recipients from the prying eyes of cybercriminals.
After Gmail and other key players, Zoho Mail is now openly supporting BIMI, allowing senders to display their brand logos with a blue verified checkmark in Zoho mailboxes. Email security risks are on the rise, stressing 95% of the top 500 cybersecurity leaders about it.
As an unsuspecting internet user, if you come across an email from someone whose email address ends with a ‘.com’ or ‘.org,’ you might not think twice before opening it. After all, it comes from one of the widely recognized TLDs (top-level domains) out there. But in the context of cybersecurity, not everything that looks legitimate is to be trusted.

Your week’s wait is over since we are once again at your service, delivering the latest news and happenings in the cybersecurity world. The news pieces are freshly curated from authentic sources, providing you with insights on recent threat landscape scenarios. The news sections we cover further down the article include significant data breaches affecting healthcare providers, Microsoft’s latest patch addressing its vulnerabilities, the FBI’s warning about usage of hacked police email accounts, the rise of the new Interlock ransomware, and finally, the success of CISA’s ScubaGear tool, improving Microsoft 365 security configurations in cloud settings. Let’s explore and understand each section in detail.
Email domains use DNS to secure communications from eavesdroppers. They aim at preventing phishing, spoofing, ransomware, and impersonation attacks. DNS records also include a DMARC record, which is implemented and configured by the owner of the specific domain with the intention of allowing only authorized entities to send emails from that domain. A DMARC record consists of DMARC policies that instruct the receiving server on how to deal with unauthorized emails sent from your domain. By unauthorized emails, we mean outgoing emails from your domain that didn’t pass the DMARC checks.
AI is everywhere, from your smartphones and home appliances to high-efficiency systems in workplaces and industries. It is officially the era of artificial intelligence, where bots have taken over almost every domain, including cybersecurity.
DMARC’s purpose of instructing receiving servers on how to handle unauthorized emails from your domain is achieved based on what policy you have set in your DMARC record. While p=reject is undoubtedly the strictest policy, there are conditions in which it isn’t a suitable one.
