Breaches & Lessons

What 2025 revealed about cybersecurity in high-risk industries, from failing assumptions and credential exposure to cloud misconfigurations and GenAI risk.

Anthropic’s latest report reveals a state-sponsored intrusion in which an AI system executed nearly the entire attack lifecycle autonomously. Using Claude Code, the threat actor automated reconnaissance, exploitation, credential harvesting, lateral movement, and data extraction at machine speed. This incident signals a major shift in how organisations must think about intrusion risk, detection windows, identity security, and continuous defence.

In 2024, UnitedHealth’s Change Healthcare hack and 23andMe’s data breach exposed a shared weakness: broken authentication. From a missing MFA control to optional security features, both incidents show how fragile healthcare systems become when trust mechanisms fail. Here’s what went wrong — and how to build resilience before the next breach.

The NHS has faced a series of high-impact hacking attacks in recent years — from the infamous WannaCry ransomware outbreak in 2017 to the...

When Regeneron announced its $256 million acquisition of 23andMe, most headlines focused on drug discovery potential. But beneath the surface lies a deeper concern: the fate of 15 million genetic profiles. At Sekurno, we unpack the post-acquisition security risks, Regeneron’s breach history, and why compliance alone isn’t enough to protect the world’s most personal data—your DNA.

Explore the anatomy of the 23andMe data breach, its impact on genomic privacy, and critical lessons for biotech security. This deep dive reveals how sensitive genetic data was compromised and what organizations must do to strengthen defenses.
