While most of the activity observed occurred since October 2022, Proofpoint researchers identified multiple activity clusters since 2019 that overlap with TA866 activity. Most of the activity recently observed by Proofpoint suggests recent campaigns are financially motivated, however assessment of historic related activities suggests a possible, additional espionage objective.",
