Microsoft on Tuesday said it took steps to disable fake Microsoft Partner Network (MPN) accounts that were used for creating malicious OAuth applications as part of a malicious campaign designed to breach organizations’ cloud environments and steal email.
“The applications created by these fraudulent actors were then used in a consent phishing campaign, which tricked users into granting permissions to the fraudulent apps,” the tech giant said. “This phishing campaign targeted a subset of customers primarily based in the U.K. and Ireland.”
