Yahoo Japan has mandated DMARC and domain authentication
Yahoo Japan has mandated DMARC and domain authentication
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…)

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.

Ensuring proper cybersecurity is at the top of every organization’s agenda this year. That explains why Microsoft cautions its Windows 10 users and asks them to upgrade their PC’s OS before the 14 October 2025 deadline. However, even the most robust cybersecurity strategies might seem inadequate, especially as three more telecoms become victims of the Salt Typhoon.
Understanding everything about DMARC records and tags
Understanding everything about DMARC records and tags
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. One such powerful tool to protect email communications is DMARC or Domain-based Message Authentication Reporting and Conformance. Its job is to authenticate email messages and take suitable action against unauthorized emails. The DMARC policy works in coordination with SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail) protocols.
