Ursnif/Gozi is malware referenced in the provided reporting as a tool family or derivative used for data aggregation and exfiltration. In the cited FBI/CISA Royal ransomware advisory, repurposed tools including Cobalt Strike and Ursnif/Gozi derivatives were used in Royal-associated exfiltration activity. The content does not provide standalone technical details on Ursnif/Gozi’s infection vector, persistence, payload execution chain, or specific indicators of compromise beyond its use for data aggregation and exfiltration in that context. The malware is therefore associated here with Royal ransomware operations, where it supported pre-encryption data theft and extortion activity affecting U.S. and international organizations, including critical infrastructure sectors such as Manufacturing, Communications, Healthcare and Public Healthcare, and Education.

3 distinct techniques documented for this family, organized by ATT&CK tactic.
They used several anti-analysis techniques, including process injection into legitimate files, such as explorer.exe or alg.exe... The latest samples are designed in such a way that the wrapper module decodes its embedded executable, launches the target process in suspended state, and writes the code to inject into the memory of it.

The response can be a simple acknowledgment or a longer set of instructions, a module or executable... In many cases the C2 server response only contains an updated version of the binary... If the victim is infected with the latest version of Emotet... the latest modules are downloaded.
