The Modus Operandi: How the Hackers Targeted Office365 Accounts

The hackers behind this multi-million dollar Office365 scheme employed a multifaceted approach, leveraging common vulnerabilities to gain access to accounts. Their methods included sophisticated phishing attacks, credential stuffing, and exploiting known vulnerabilities in third-party applications integrated with Office365. The targets were diverse, ranging from small businesses to large corporations, highlighting the indiscriminate nature of this cybercrime. Specific targets often included those with access to sensitive financial information or intellectual property.

The hackers exploited several common entry points:

• Weak Passwords and Password Reuse: Many victims used easily guessable passwords or reused the same password across multiple platforms, making them easy targets for credential stuffing attacks.
• Phishing Emails and Malicious Links: Sophisticated phishing campaigns, mimicking legitimate emails from trusted sources, lured users into clicking malicious links or downloading infected attachments, leading to malware infection and account compromise.
• Compromised Third-Party Applications: Hackers often targeted vulnerabilities in third-party applications connected to Office365, leveraging these access points to gain unauthorized access.
• Unpatched Software Vulnerabilities: Failing to update Office365 and related software left many systems vulnerable to known exploits, allowing hackers to easily breach security defenses.
