In January 2024, Microsoft detected a nation-state attack on their corporate systems by a Russian state-sponsored actor called Midnight Blizzard. The attackers compromised a legacy non-production test tenant account and accessed a small percentage of Microsoft corporate email accounts.
How many accounts were compromised?
The breach impacted data related to approximately 30 million individuals.
What data was leaked?
The data exposed in the breach included social security numbers, email addresses, names, phone numbers, employers, job titles, geographic locations, and social media profiles.
How was Microsoft hacked?
Anonymous Sudan breached Microsoft's systems using a password spray attack, compromising a legacy non-production test tenant account. They accessed a small percentage of corporate email accounts, exfiltrating emails and attached documents. Despite claims of offering the database for $50,000, Microsoft found no evidence of compromised customer data or outages caused by the attack.
Microsoft's solution
In response to the hack by Anonymous Sudan, Microsoft took several measures to enhance its security and prevent future incidents. This included applying current security standards to Microsoft-owned legacy systems, removing malware and backdoors, and collaborating with law enforcement and regulators. Microsoft also implemented additional enhanced security controls, detections, and monitoring to protect against the Midnight Blizzard attack.
How do I know if I was affected?
Microsoft has been reaching out to customers believed to be affected by the breach. If you're a Microsoft customer and haven't received a notification, you may visit Have I Been Pwned to check your credentials.
What should affected users do?
In general, affected users should:
Change Your Password: Immediately update your password for the breached account. Make sure the new password is strong and unique, not previously used on any other platform.
Reset Passwords for Other Accounts: If you've used the same or similar passwords for other online accounts, reset those as well. This is crucial as attackers often try using stolen passwords on multiple sites.
Enable Two-Factor Authentication (2FA): Activate 2FA on the breached account. Consider enabling this additional security feature on all other important online accounts to significantly reduce the risk of unauthorized access.
Monitor Your Accounts: Keep an eye on your accounts for any suspicious activity and report it immediately to the respective platform or service provider.
