Microsoft has issued urgent guidance following a significant global cyberattack linked to Chinese hacking groups that exploit vulnerabilities in its SharePoint software. Multiple U.S. agencies and over 100 organizations have reportedly been affected, prompting a scramble for security updates. Microsoft acknowledged that it was aware of the critical vulnerabilities but failed to implement effective patches. Despite the release of updates, concerns persist as some versions remain vulnerable. The FBI and cybersecurity firms warn that these zero-day exploits pose an active threat, particularly highlighting the ongoing exploitation by state-sponsored actors. As the situation unfolds, businesses and government agencies are urged to take immediate action to secure their systems.
