Latest Email Phishing Scam Targets Office 365 Users

In recent weeks we have witnessed an increase in phishing attacks targeting businesses and consumers who use Office 365 email services. Unscrupulous syndicates are coordinating efforts to gain access to Office 365 accounts by stealing login credentials obtained using convincing fake login screens.

Fraudster email attacks are becoming increasingly sophisticated – often appearing to be sent from a business, organization, or individual the victim normally emails or does business with. The fictitious emails contain malicious links or attachments that redirect the victim to a fake login page asking for their email username and password. Once the information is entered, fraudsters then use the stolen credentials to log into Office 365 and send fraudulent emails to the victim’s contact list, perpetuating the scam. We have also seen the interception of email communications between legitimate parties and then fraudulent requests for invoice payments.

If you use Office 365 for email, we encourage you to be extra vigilant. Emails containing hyperlinks or attachments that require additional actions by you should be carefully vetted before proceeding. If you are unsure if an email you received is legitimate, do not click on any links, attachments, or provide any information.

If you think you may have fallen victim to this scam, immediately contact your IT Support team or NETCONFIG to:

We also encourage you to contact any of your email contacts via phone or a safe email address to inform them that your email account has been compromised and to let them know they may receive fraudulent emails appearing to be sent by you.

Signs your account may have been compromised include:

NETCONFIG recommends taking the following preventative measures to protect you and your organisation:

While Office 365 is the most recent phishing target, these types of scams regularly impact other email applications and platforms as well. Always be cautious when opening any emails that were not expected, are coming from someone you do not know, and contain links or attachments you were not expecting. Whilst the threat landscape is ever evolving. As these threats evolve NETCONFIG will ensure we take a best practice approach at all times however there is the human element that we cannot control.

One of the most common targeted attacks at the moment is that once your account has been compromised, these criminals will setup an Email Forwarding rule on all your incoming and outgoing email.
