Who They Target.
About Hydrochasma.
Shipping companies and medical laboratories in Asia are being targeted in a likely intelligence-gathering campaign that relies exclusively on publicly available and living-off-the-land tools. Hydrochasma, the threat actor behind this campaign, has not been linked to any previously identified group, but appears to have a possible interest in industries that may be involved in COVID-19-related treatments or vaccines. This activity has been ongoing since at least October 2022.
