**[Security Boulevard](https://daily.dev/sources/securityboulevard)** · 5 min read · 0 upvotes · 0 comments

## Summary

A roundup of recent security incidents illustrating how breaches expand once initial access is gained. Cases covered include email compromise at Aitkin County Health and Human Services exposing PHI for 83,114 individuals, an insider access incident at Washington DSHS affecting 8,600 records, the FortiBleed campaign targeting Fortinet devices with 86,000+ stolen credentials, a CVE in Microsoft Defender enabling privilege escalation, and a Tata Electronics supply chain breach leaking 200,000+ files including Apple and Tesla data. The post recommends microsegmentation, restricting lateral movement, removing stored credentials, and extending incident response plans to cover insider and contractor compromise scenarios.
