Suspected China-backed hackers have breached the email accounts of U.S. Commerce and State Department officials, potentially gaining access to sensitive documents and files protected by Microsoft login information, according to researchers. The attackers used a stolen or forged Microsoft signing key, which allowed them to impersonate any Microsoft Exchange or Outlook email customer and approve access to employee inboxes. Researchers from cloud security company Wiz found that the compromised key could have also been used to sign into other widely used Microsoft cloud offerings, including SharePoint, Teams, and OneDrive. Microsoft has since revoked the key, but Wiz warned that the attackers may have left back doors in applications, and some software may still recognize a session initiated by the expired key. Microsoft downplayed the possibility that the attackers had gone beyond the email accounts of their targets, which included Commerce Secretary Gina Raimondo and U.S. ambassador to China Nicholas Burns. The Cybersecurity and Infrastructure Security Agency stated that there was no evidence to suggest that the attackers had expanded their access beyond email. Microsoft has attributed the attack to a Chinese group and is investigating how the signing key was obtained.

Attention-grabbing headline: Chinese Hackers Breach US Government Email Accounts, Unleashing Potential Chaos
Suspected China-backed hackers have successfully infiltrated the email accounts of high-ranking officials from the US Commerce and State Departments, raising concerns over the exposure of sensitive documents and files protected by Microsoft login information. Researchers have discovered that these hackers employed a stolen or forged Microsoft signing key, granting them the ability to masquerade as any Microsoft Exchange or Outlook email user and gain unfettered access to employee inboxes. Shockingly, the compromised key could have also been used to infiltrate other widely utilized Microsoft cloud services such as SharePoint, Teams, and OneDrive. Although Microsoft has promptly nullified the key, cloud security company Wiz has issued a stern warning, suggesting that the perpetrators may have implemented hidden vulnerabilities in various applications. Consequently, certain software systems may still recognize an initiated session originating from the expired key, leaving them susceptible to unauthorized access. While Microsoft has downplayed the extent of the breach, insisting that the hackers were restricted to the email accounts of their targets, which notably include Commerce Secretary Gina Raimondo and U.S. ambassador to China Nicholas Burns, doubts remain. The Cybersecurity and Infrastructure Security Agency asserts that there is no conclusive evidence to support the notion that the attackers have expanded their reach beyond email. Microsoft, attributing the attack to a Chinese group, is currently conducting an investigation to determine the exact method by which the signing key was obtained.
