Microsoft users are being targeted with thousands of phishing emails, in an ongoing attack aiming to steal their Office 365 credentials. At least 2,500 such emails have been unsuccessfully sent to senior-level employees in the banking and IT sector, over the past three months. The attackers add an air of legitimacy to the campaign by leveraging a fake Google reCAPTCHA system and top-level domain landing pages that include logos of victims companies. The attack is notable for its targeted aim at senior business leaders with titles such as Vice President and Managing Director.
