Microsoft launched an internal investigation after the SharePoint system was hacked and leaked information.

Microsoft is attracting attention due to potential vulnerabilities in its self-inspection defense system. According to reports, the company is investigating whether there has been information leakage in its early warning system aimed at cybersecurity companies, allowing foreign hackers to infiltrate its SharePoint services. Earlier reports indicated that at least three hacker groups had exploited vulnerabilities in internet-facing SharePoint servers to launch attacks. Microsoft's security team is currently examining whether its alert system meant to provide threat warnings to partners accidentally exposed these security weaknesses.
