RaccoonO365 is a subscription-based phishing-as-a-service platform that supplies cybercriminals with phishing templates, infrastructure, and counterfeit Microsoft 365 sign-in portals for credential harvesting and account takeover. Its kits impersonate Microsoft 365 and other commonly trusted brands, and campaigns have used email attachments, embedded links, and QR-code lures to direct victims to fraudulent authentication pages. The service has included mechanisms intended to circumvent multifactor authentication protections. RaccoonO365 activity has targeted corporate, financial, educational, engineering, IT, consulting, and healthcare organizations internationally, facilitating business email compromise, unauthorized mailbox access, data breaches, and financial fraud. Microsoft and Cloudflare disrupted infrastructure associated with the service in 2025, and Nigerian authorities arrested suspects alleged to have operated or developed it.
