The largest security breach in the history of Microsoft Azure occurs.

According to Proofpoint, a cybersecurity firm, the attack employs the same malicious campaign detected in November 2023, utilizing phishing techniques and cloud account takeover (CTO) to facilitate unauthorized access to OfficeHome and Microsoft 365 applications.

The hackers purportedly utilized proxy services to evade geographical restrictions and conceal their identities. They embedded links within documents, often disguised as innocuous "View document" prompts, redirecting users to phishing websites.

The attack was meticulously planned, focusing on both mid-level and senior employees, with a larger number of compromised accounts belonging to the former. Proofpoint notes that positions such as sales directors, account managers, financial directors, operations vice presidents, and CEOs were the most frequent targets, enabling attackers to access information across various organizational levels and domains.

Following a successful compromise, cybercriminals typically implement their own multifactor authentication (MFA) measures to prolong access, such as adding alternate contact information or setting up authentication apps, effectively preventing legitimate users from regaining control. Additionally, attackers systematically eliminate traces of suspicious activity to cover their tracks.

The primary objectives of these cyber attacks include data theft and financial fraud. While the exact perpetrators remain unidentified, the utilization of local fixed-line ISPs in regions like Russia and Nigeria suggests potential origins in these areas.
