US State Department enhances cybersecurity post Microsoft breach

May, 09, 2024 Hi-network.com

Following a major cyberattack last year that saw China-linked hackers infiltrate the US Department of State's network, the agency has expanded its cybersecurity efforts beyond its reliance on Microsoft. This reinforcement of the defence strategy comes after the breach compromised around 60,000 State Department emails, including those of high-profile officials like Commerce Secretary Gina Raimondo. Criticism was directed at Microsoft, with the Cyber Safety Review Board questioning the company's transparency regarding the incident.

Kelly Fletcher, the department's chief information officer, highlighted concerns about the security of corporate networks, emphasising the importance of all vendors ensuring secure systems. The hacking group, identified by Microsoft as Storm-558, obtained access to a digital key, allowing them to breach government inboxes. Despite tensions, the embassy of China in Washington denied any involvement of Chinese government-linked hackers in the attack.

In response to the breach, the US State Department has diversified its vendor portfolio, incorporating companies like Palo Alto, Zscaler, and Cisco alongside Microsoft. While Microsoft managed to revoke the hackers' access, Fletcher expressed concerns over the potential broader impact of the breach. The department has since bolstered its security measures, including multifactor authentication and data encryption, significantly increasing cybersecurity fundamentals across its systems.

Despite criticism, Microsoft remains a key player in the State Department's cybersecurity framework. The agency thoroughly analysed its communications with Microsoft following a separate breach linked to Russian hackers, concluding that sensitive information was not compromised. With ongoing efforts to fortify its cybersecurity posture, the State Department aims to mitigate future threats and maintain the integrity of its digital infrastructure.
