Microsoft is investigating a potential leak from its MAPP that allegedly informed Chinese hackers about a SharePoint vulnerability before a public patch, affecting over 400 organizations including US government agencies.
This incident highlights potential vulnerabilities within Microsoft’s alert system, emphasizing ongoing challenges in information security and its impact on enterprise and governmental operations globally.
Microsoft is investigating whether a MAPP leak alerted Chinese hackers to exploit a SharePoint vulnerability. Over 400 organizations, including US government agencies, are affected. This issue came before the public patch release.
The Microsoft Security Response Center is scrutinizing the leak’s source believed to involve Chinese groups like Linen Typhoon. MAPP partners receive early access for responding to critical security concerns before public alerts.
5% Impact Expected on Microsoft Shares Amid Leak
While the Microsoft shares see only modest fluctuation, analysts suggest a 5% price impact unless more vulnerabilities emerge. The primary risk affects Microsoft’s corporate users rather than the crypto market.
Although the enterprise market faces risks, the crypto sector remains largely unaffected. BTC, ETH, and related tokens do not experience significant impact due to this event, avoiding any on-chain disruptions.
Recurring MAPP Leaks Raise Security Concerns
Previously, Microsoft experienced similar MAPP-related leaks such as the 2021 Exchange Server vulnerabilities incident linked to Chinese hackers. These recurrences highlight the ongoing challenges regarding vulnerability information sharing.
According to Dustin Childs, the Zero Day Initiative, the leak may originate from a Chinese MAPP partner. Historically, such events spur debates on the effectiveness of pre-public disclosures and operational security protocols.
Dustin Childs, Head of Threat Awareness, Trend Micro’s Zero Day Initiative, – “The likeliest scenario is that someone in the MAPP program used that information to create the exploits. Since many of the exploit attempts come from China, it seems reasonable to speculate it was a company in that region.”
