Microsoft has just revealed that its systems were compromised sometime in 2019, and that hackers were able to access some of the e-mail information of the company's users.
In an email sent to all users involved (posted by TechCrunch), Microsoft explains that someone managed to breach an account of a Microsoft support employee.
This allowed non-Microsoft employees to access information stored in Microsoft e-mail accounts (@ outlook.com, @ hotmail.com, @ msn.com) and, according to the company, businesses were not affected.
The information that hackers allegedly have includes email addresses, folder names, email subject lines, names of other email addresses that users contact. According to the company, the contents of the emails or attachments were not exposed.
The unauthorized access allegedly took place from January 1, 2019 until March 28, 2019, Microsoft reports, but did not provide further details on how the hackers managed to breach the account of the support employee.
The company states that it immediately deactivated the breached account as soon as it detected the breach.
"Once aware of this issue, Microsoft immediately deactivated the affected account, prohibiting its use for any further unauthorized access. "Our data suggests that account information (but not the content of any e-mail) could have been leaked, but there is no indication that this information has been made public or how it may have been used." e-mail sent to affected users.
Microsoft now warns of increasing numbers of phishing emails that could be sent to users and recommends that everyone change their passwords. However, it is important to know that the passwords were not leaked (always according to the company).
It is not yet known how many users are affected by the hack.
