STALECOOKIE is an Android malware used in Russia-linked operations targeting Ukrainian military/government users and battlefield technology. It has been reported as masquerading as Ukraine’s DELTA battlefield management platform (and more broadly mimicking battlefield management platforms) to socially engineer installation/use, with the primary described capability of stealing browser cookies from infected Android devices. The activity is associated in reporting with Russian threat clusters UNC4221 (UAC-0185) and also mentioned alongside UNC5792 (UAC-0195) as part of malware deployed in these campaigns. In the same operational context, STALECOOKIE is referenced together with other Android tooling (e.g., TINYWHALE and MeshAgent) used to enable remote management, but the specific behavior explicitly attributed to STALECOOKIE in the provided content is cookie theft via DELTA-themed impersonation.
