Scammers Exploit Microsoft's System to Send Spam Emails

Spammers are abusing an internal Microsoft email address to send spam links, potentially tricking users into thinking they are genuine. Microsoft's internal email account is being exploited by scammers to send spam emails, a practice that has been ongoing for several months.

For months, scammers have been taking advantage of a loophole that allows them to send spammy emails from an internal Microsoft email address typically used for sending legitimate account alerts.

It's not clear how the scammers are abusing the system, but they have been able to set up new Microsoft accounts as if they are new customers, and use that access to send out emails purportedly from the tech giant itself.

Microsoft doesn't yet appear to have gotten a handle on the issue.

Emails Containing Spam Links

Several emails containing subject lines and web links to scammy sites from Microsoft have been sent to different email accounts. These emails were sent from msonlineservicesteam@microsoftonline.com, an email account that Microsoft uses to send important notifications to users, such as two-factor authentication codes and other critical alerts about their online account.

Some of these emails' subject lines resembled official emails that would alert users to fraudulent transactions, while other emails claimed to have a private messaging waiting for the recipient at a web address mentioned in the email body.

The Spamhaus Project Notifies Microsoft

The Spamhaus Project, an anti-spam non-profit, said it had also seen Microsoft's account notification email address being abused to send spam, and that the activity dated back "several months." "Automated notification systems should not allow this level of customization," wrote Spamhaus. The non-profit added that it has notified Microsoft of the issue.

A Larger Problem

This is the latest in a rash of incidents in which hackers or scammers have abused company systems to trick unsuspecting customers in recent months. Earlier this year, hackers broke into a platform used by fintech firm Betterment to send out fraudulent notifications that purported to triple the value of any crypto users send in — a widely known scam used to steal people's cryptocurrency.

Back in 2023, hackers similarly abused access to an email account run by Namecheap to send out phishing emails aimed at stealing people's credentials.

Other users commenting on social media say that other companies' email addresses are also being used to send out spam, suggesting the issue is not limited to Microsoft.

Conclusion

Microsoft's internal email account is being exploited by scammers to send spam emails, potentially tricking users into thinking they are genuine. The company needs to take immediate action to address this issue and prevent further abuse of its system.
