We hate to break it to you, but no matter how much you try, you cannot be invincible against malicious cyberattacks. Cybercriminals realize that email is the backbone of your organization’s communication infrastructure, which is why they leave no chance to exploit vulnerabilities. From phishing attacks to domain spoofing and business email compromise (BEC), threat…
SPF is a DNS-based email authentication protocol that allows domain owners to specify which email servers are authorized to send emails on behalf of their domain. When an email is received, the recipient’s server checks the SPF record to verify if the sending server’s IP address is authorized. This process ensures that emails sent by…
Hola people! We hope you have managed to keep those menacing cybercriminals at arm’s length with your knowledge and vigilance. We are back again with the third bulletin of the month. This edition will cover important topics like DeepSake’s failure to cater to security checks, Japan’s newly formed ‘Active Cyber Defense’ bill, and the nomination…
Here’s a harsh truth: Email is not inherently secure, and it never was! Back in 1995, when the primitive version of SMTP (Simple Mail Transfer Protocol) was introduced, it was only supposed to ensure that emails were being delivered; there was nothing done to confirm their authenticity and legitimacy. It was this lack of security…
The last two decades have witnessed a steep surge in cyberattacks, and 2025 is not going to be any different. What’s extremely concerning is that as many as 3.4 billion emails are sent out by threat actors every single day! This is precisely why businesses, as well as individuals, must prioritize cybersecurity at any cost….
It’s the second week of February, and we are back once again with our weekly dose of fresh cyber news. Threat actors around the world are trying their best to sneak into systems and networks to impart critical damage. Meanwhile, cybersecurity experts are doing their best to curb this growing menace. Experts believe that rapid…
An ‘envelope_to’ domain is the domain in the recipient’s email address. This address can be used to understand how some of the legitimate emails are failing DMARC checks. If you are unsure about the troubleshooting methods, using the ‘envelope_to’ domain to find the source owner is a wise choice. Using this technique, you get to…
A fresh new month, a brand new starting. Yes, it is the month of February, and some of you are aiming to crush your Q1 2025 goals, while others are getting a bit tired of the 2025 New Year resolution rush. Businesses, brands, and e-commerce platforms are running lucrative offers to lure consumers into splurging…
A broken SPF record doesn’t act as a defense mechanism against phishing and spoofing attacks. In fact, a broken SPF record itself acts as a security vulnerability that a threat actor can exploit at any time. The main reasons why an SPF record breaks are misconfigurations, incomplete listings of mail servers, or failure to stay…
RFC 5322 defines the syntax for Internet email headers. SPF, DKIM, and DMARC rely on these headers to authenticate emails and prevent phishing. Published in October 2008 as an update to RFC 2822, RFC 5322 is widely used for formatting email headers and bodies. RFC 5322 doesn’t say anything about how SPF should be set…
