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.

The researchers currently divide the APT-Q-31 (OceanLotus) group into two attack sets, after they have observed for a long time that the old and new OceanLotus carry out espionage activities against the country alternately every year through rounds of warfare, and that the two attack sets have completely different TTPs, but share attack resources. The last time the new OceanLotus group was active was at the end of 2023, so far it has been exactly one year.
