Why users fall for Office 365 phishing attacksĪttackers mimic the protocols and appearance of Office 365 messages and interfaces to trick users into disclosing their login credentials. Moreover, they’re able to acquire more Office 365 credentials and spread across other organizations. Moving freely within Office 365, the hacker can impersonate employees to request wire transfers and gift cards, demand ransoms, and more. With a single set of legitimate Office 365 credentials, a hacker can move on to phase two of the attack: spear phishing, which is ultimately about the financial payout.
Whether corporate trade secrets or financial information, the productivity and collaboration suite houses business-critical data that, if exposed, could cause irreparable damage. More than one million businesses use Microsoft 365 worldwide. Together, they represent a wealth of sensitive data and files, making Office 365 phishing attacks a lucrative business for hackers.
A multisystem platform, Office 365, now Microsoft 365, combines email, file storage, collaboration, and productivity applications, including OneDrive and SharePoint. Microsoft was the second most impersonated brand in phishing attacks in 2021-thanks to Office 365. On top of all the standard phishing and spear phishing threats, Office 365 presents a number of unique attack techniques for hackers looking to compromise accounts. With 258 million corporate users, the highly popular Microsoft platform has become a target-rich environment for sophisticated Office 365 phishing attacks.
