Storm-237
Storm-237 is a Russian threat group identified in the provided content as one of several actors known to use device code phishing. Specifically, the group has been associated with abuse of the OAuth 2.0 device authorization flow to trick victims into authorizing attacker-controlled devices against Microsoft accounts. This technique can yield access and refresh tokens, enabling immediate and persistent access to victim email, files, Teams data, and other SSO-enabled Microsoft services. In the cited context, Storm-237 is listed alongside UTA032, UTA0355, UNK_AcademicFlare, and TA2723 as Russian groups that have used this technique. No additional high-confidence details on targeting, sub-groups, or operations beyond device code phishing are provided in the content.
