Major brands—including Hawaiian Airlines, Qantas, Aflac, and Cartier—have been hit in recent weeks, with groups like Scattered Spider exploiting help desk vulnerabilities to bypass MFA. Experts warn that cloud exposure, poor segmentation, and inadequate defenses are leaving critical systems vulnerable.

Remember to implement strong personal security measures, like long passphrases and MFA, when creating accounts on vendor websites, and continuously monitor your credit reports for suspicious activity.

Ohio’s Capital Proposes $23M Zero Trust Overhaul One Year After Devastating Cyberattack

Nearly a year after the Rhysida ransomware gang breached Columbus’ systems and leaked sensitive data on the dark web, the city is considering a $23 million investment to overhaul its cybersecurity defenses. 

The proposal would fund the implementation of a zero-trust network architecture. This upgrade aims to modernize infrastructure, limit lateral movement within the network, and protect against increasingly sophisticated threats targeting public sector entities.

Always incorporate zero-trust principles to strengthen your cyber resilience and adopt this posture by default.

UK Taps Hacker Talent: New Initiative Targets Cyber Vulnerabilities

The UK's National Cyber Security Centre (NCSC) has unveiled the Vulnerability Research Initiative (VRI), a new program designed to partner with external cybersecurity researchers to help the country identify and understand critical software and hardware flaws.

While the agency will continue internal research, the VRI establishes a structured collaboration framework that enables vetted experts to help identify vulnerabilities, evaluate mitigations, and contribute methodologies—all within a coordinated disclosure process.

The UK is turning to outside experts for help. You can also contribute by reporting any issues you spot.
