Welcome back to another edition of Talking Security – Let’s Talk! In this monthly update, we dive into the latest cybersecurity developments, industry insights, and upcoming events. If you missed the episode, here’s a summary of the key topics we covered!
Safer Internet Day 2025
On February 11, 2025, we celebrate Safer Internet Day under the theme “Together for a Better Internet.” This initiative calls on stakeholders to collaborate in making the internet a safer place, especially for children and young people. Microsoft is actively contributing to this effort by addressing abusive AI-generated content risks through education and empowerment.
DeepSeek Database Leak
A significant data exposure incident was uncovered by Wiz researchers, revealing a publicly accessible ClickHouse database linked to DeepSeek. This misconfiguration exposed sensitive chat history, backend data, API secrets, and operational details. More critically, the lack of authentication enabled potential privilege escalation within the DeepSeek environment. Read the full research here.
Microsoft Defender Updates
Several major updates were rolled out across the Microsoft Defender suite:
- Defender for Endpoint: Preview of aggregated reporting to reduce event sizes while maintaining essential properties.
- Defender for Office: The built-in Report button in Outlook (iOS & Android) now supports user-reported phishing, junk, and non-junk messages.
- Defender for Identity: New Attack Paths tab provides visibility into potential attack vectors involving critical identities. Additional updates include an improved user timeline and enhanced Advanced Hunting capabilities in Defender XDR.
Microsoft Sentinel Enhancements
Microsoft continues to evolve Sentinel with key improvements:
- Defender Threat Intelligence data connectors are now generally available (GA).
- Threat intelligence upload API now supports additional STIX objects for better integration with security operations.
- SIEM-as-Code capabilities in Sentinel Repositories enable organizations to manage configurations at scale.
