How are DMARC enforcement and DMARC reporting different?
by DuoCircle
Domain-based Message Authentication, Reporting, and Conformance (DMARC) is one of the most powerful tools that security teams rely on to combat email-based attacks such as phishing, spoofing, and Business Email Compromise (BEC). Essentially, this tool enables domain owners to protect their domains from scammers by specifying how emails should be handled if they fail authentication checks. But the best part about DMARC is that it goes beyond enforcing policies to block malicious emails; it gives you insights into all that’s going on with your domain and its email traffic. We are talking about the reporting aspect of DMARC, which works hand-in-hand with enforcement to create a complete email security system.
5 efficient email security techniques for advanced persistent threats
by DuoCircle
An advanced persistent threat (APT) is a sophisticated, prolonged cyberattack in which a malicious actor gains access to a network and remains undetected for an extended period. This type of cyberattack is often motivated by political, financial, or strategic interests and aims to steal sensitive data, disrupt operations, or conduct espionage.
In this week’s cyber update, let’s examine the following case scenarios closely: a significant email data breach affecting multiple healthcare organizations, the discovery of a new Wi-Fi exploit used in targeted attacks, a malware campaign exploiting an outdated Avast driver, a high-profile extortion campaign targeting cloud storage platforms, and recent intrusion attempts on telecom infrastructure. These headlines are followed by matter-expert suggestions highlighting best practices one could follow to mitigate potential risks in the future.
How do we fix the custom domain configuration problems for Azure Email Communication?
by DuoCircle
Email deliverability is the backbone of email marketing campaigns; your effort in strategizing and executing the campaign will go to complete waste if half of your emails don’t reach the inboxes of the intended recipients. If you have deployed email authentication protocols like SPF and DKIM and ensured their TXT records aren’t amiss, receiving mail servers will consider emails sent from your domain by authorized senders as genuine and, hence, will not hesitate to place them in the inboxes.
Understanding the ins and outs of attack simulations
by DuoCircle
Attack simulation is a cybersecurity technique that tests defenses by imitating tactics, methods, and procedures used by threat actors to exploit vulnerabilities and launch attacks. Its purpose is to spot system vulnerabilities and help the security team remediate them before someone capitalizes on them for malicious purposes.
BreakSPF attack- working, impact, and preventive measures
by DuoCircle
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.

A roundup of TLDs that were the prime target of cyber attackers in 2024
by DuoCircle
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.
