Yahoo Japan has mandated DMARC and domain authentication
by DuoCircle
In November 2023, Yahoo announced that by February 1st, 2024, any company that sends more than 5,000 emails per day has to deploy DMARC to minimize the risk of email-based spoofing, phishing, and ransomware. After this announcement, the rate of DMARC adoption surged, and now Yahoo Japan has also made DMARC and domain authentication mandatory for users as of December 2024. Experts see this as a great opportunity to improve companies’ email security posture.(more…)
Back in 2024, email service providers such as Google and Yahoo rolled out new email-sending policies. One would have thought that organizations would begin to take email security more seriously, but so far, that hasn’t been the case. In fact, cybersecurity experts have found that phishing attacks have shot up, with the number of phishing messages increasing by 202% in the second half of 2024.
Cybercriminals are enhancing their capabilities, as evidenced by the latest PhishPWP phishing threat. Similarly, this week’s cybersecurity bulletin highlights the latest ransomware attack on AWS servers, making recovery impossible without the attacker’s key. We also look at how cybercriminals use popular social media channels like Telegram. Zero-day attacks are the most dangerous of all, as they emerge from practically nowhere. This week’s news highlights one such attack on Fortinet FortiGate firewall users. Finally, we round off a reputed university shutting off classes, fearing a cyber-attack on its network.

Email security is a growing concern for businesses and individuals alike. Increased email spoofing and phishing attempts have made it crucial to implement security measures to safeguard communication channels.
