Microsoft’s SharePoint Snafu: Chinese Hackers Exploit Zero-Day Chaos
Microsoft says Chinese threat actors exploited SharePoint zero-day vulnerabilities weeks before patches. Yet, confusion reigns over which CVEs were actually exploited. With nation-state actors involved, it’s a cybersecurity whodunit. Maybe we should ask Linen Typhoon or Violet Typhoon if they left any crumbs behind!
Hot Take:
Microsoft’s latest SharePoint zero-day drama is akin to a cybersecurity soap opera with a plot twist every commercial break. As Chinese threat actors allegedly exploit these vulnerabilities, Microsoft’s attempts to shed light just leave everyone squinting at their screens in confusion. Can someone pass the popcorn, please?
Key Points:
- Chinese threat actors exploited SharePoint zero-days, dubbed ToolShell, before patches were released.
- Microsoft’s timeline suggests earlier awareness of vulnerabilities by Chinese hackers.
- Confusion persists over which specific CVEs were exploited in these attacks.
- WatchTowr claims CVE-2025-53770 and CVE-2025-53771 have been chained in attacks.
- Over 9,000 SharePoint instances were exposed, with hundreds targeted immediately.
