New Trend in MSI File Abuse: New OceanLotus Group First to Use MST Files to Deliver Tromas


During recent daily operations, the QiAnXin Threat Intelligence Center discovered that the new OceanLotus group, which we have been continuously tracking since mid-2022, has begun to re-activate and is using a new tactic of MSI file misuse.
