Ericsson's US subsidiary disclosed a data breach affecting roughly 15,000 people after unauthorized access occurred at a third-party service provider between April 17-22, 2025. The breach wasn't discovered until April 2025, with the investigation only wrapping up in February 2026. The telecommunications giant shares both employee and customer data with third-party providers but hasn't specified which group was impacted. While Ericsson claims there's "no evidence of misuse," security experts note this is standard language companies use even when stolen data surfaces publicly. The delayed discovery and lengthy investigation timeline raise questions about monitoring practices at third-party vendors handling sensitive information. **Source:** [Security Week](https://www.securityweek.com/thousands-affected-by-ericsson-data-breach/)
