Microsoft anounced that it ha srecently faced a breach affecting its web-based email services.
The company said that a certain “limited” number of people who use web email services managed by Microsoft — which cover services like @msn.com and @hotmail.com — had their accounts compromised.
“We addressed this scheme, which affected a limited subset of consumer accounts, by disabling the compromised credentials and blocking the perpetrators’ access,” said a Microsoft spokesperson.
Microsoft has already sent out emails to affected users, informing them that hackers were potentially able to access an affected user’s e-mail address, folder names, the subject lines of e-mails, and the names of other e-mail addresses the user communicates with. Content of any e-mails or attachments along with login credentials were not compromised, according to Microsoft.
Microsoft is still recommending that affected users change their passwords regardless.
The breach occurred between January 1 and March 28. The compromises only include consumer Outlook.com accounts, not commercial (business) accounts of any kind.
The hackers managed to break into a Microsoft customer support agent’s credentials.
