A new phishing campaign aimed to steal employees’ login credentials by impersonating Microsoft Teams’ notifications.
Due to this COVID-19 pandemic situation, many companies moved to full-time remote work, attackers taking advantage of it.
Fake Microsoft Teams Notifications
Attackers use crafted emails that appear to be automated notifications emails coming from Microsoft Teams.
Once the user click’s in the email it takes them to the fake landing that impersonates the real webpages of Microsoft Teams.
The campaign was observed by Abnormal Security, according to researchers the “sender email originates from a recently registered domain, “sharepointonline-irs.com”, which is not associated with either Microsoft or the IRS.”
Attackers used numerous URL redirection to evade malicious link detection and hide the original URL used to launch the attack.
Researchers observed two such attacks that try to steal employee login credentials
- In one such attack, the email includes a link to a document that contains an image that urges recipients to login with Microsoft team, upon clicking the image it takes to the fake Microsoft Office login page.
- In another, a Youtube link, redirected multiple times, and reaches a final webpage that impersonates Microsoft login page.
If a recipient falls victim to the attacks, their login credentials get compromised, attackers may gain access to Microsoft Office 365 services also. The attack targets more than 50,000 employees to steal login credentials.
