Return To ArticleGlobal tax and auditing firm Deloitte has confirmed the company had suffered a cyber attack that resulted in the theft of confidential information, including the private emails and documents of some of its clients.
Deloitte is one of the largest private accounting firms in the U.S. which offers tax, auditing, operations consulting, cybersecurity advisory, and merger and acquisition assistance services to large banks, government agencies and large Fortune 500 multinationals, among others.
Hackers managed to gain access to the Deloitte’s email server through an administrator account that wasn’t secured using two-factor authentication (2FA), granting the attacker unrestricted access to Deloitte’s Microsoft-hosted email mailboxes.
Besides emails, hackers also may have had potential access to “usernames, passwords, IP addresses, architectural diagrams for businesses and health information.”
