From mid-2024 to early 2026, the Vietnam-aligned APT group OceanLotus has intensified its focus on domestic espionage, utilizing the SPECTRALVIPER backdoor in two major campaigns. The first campaign targeted a Vietnamese infrastructure and transport construction company, while the second involved a supply-chain attack on FireAnt MetaKit, a stock investment platform, affecting investors in Vietnam. The SPECTRALVIPER malware, a sophisticated 64-bit Windows backdoor, was deployed to compromise systems and gather intelligence. This shift in tactics reflects a broader trend of increased domestic monitoring amid Vietnam's anti-corruption efforts. OceanLotus, also known as APT32, has a history of targeting dissidents and foreign corporations, but its recent activities indicate a strategic pivot towards local targets. The group remains active and continues to innovate its malware arsenal, suggesting ongoing threats to Vietnamese entities.
