Subdomailing: The DMARC risk you might be ignoring
Subdomailing: The DMARC risk you might be ignoring
In 2024, Guardio’s email protection systems identified unusual patterns in email metadata, related explicitly to SMTP servers and their authentication as legitimate senders. Upon investigation, it was discovered that this campaign has been ongoing since at least 2022 and involves over 8,000 domains and 13,000 subdomains owned by legitimate companies, including those belonging to MSN, McAfee, eBay, and VMware, which were compromised due to subdomain hijacking. This research led to the coining of a new term—subdomailing.

SPF in a DMARC-DKIM world: is it still relevant?
Email was never actually built with keeping security in mind. Back in the day, it was just a medium of communication, and it operated on trust. This made it a vulnerable target for threat actors who started exploiting email for spoofing, phishing, and spam. Over the years, email threats evolved, triggering the need for authentication mechanisms to verify if the sender is actually who they are claiming to be and protect recipients.

The early-2025 global posture of DMARC
The early-2025 global posture of DMARC
It’s been more than a year since Google and Yahoo pushed domain owners to adopt DMARC. This push has paid off partially— why partially? Because the number of domains with DMARC has doubled, but they aren’t configured strictly. Domain owners have just implemented DMARC for the sake of it, but have done nothing to advance the policies and strengthen email security. As per a survey done by Mailgun, 66% of senders are aware that they are using both SPF and DKIM for email authentication. About 25.7% of respondents don’t know how their organizations are using DKIM and SPF, and less than 9% said they are using only one of the two.

Bypassing DKIM: Understanding replay attacks and how to mitigate them
Threat actors always try to stay ahead of the curve and find ways to bypass security protocols. DKIM replay attacks are exactly that. In a DKIM replay attack, a cybercriminal resends a DKIM-signed message to multiple recipients without the emails getting flagged. They generally target highly reputed domains to generate legitimate message signatures. Gmail recipients, in particular, are more likely to receive replayed emails because it greatly prioritizes domain reputation.
