We investigated a long-running espionage campaign, dubbed A41APT, targeting multiple industries, including the Japanese manufacturing industry and its overseas bases, which has been active since March 2019. The attackers used vulnerabilities in an SSL-VPN product to deploy a multi-layered loader we dubbed Ecipekac (aka DESLoader, SigLoader and HEAVYHAND). We attribute this activity to APT10 with high confidence. Most of the discovered payloads deployed by this loader are fileless and have not been seen before. We observed SodaMaster (aka DelfsCake, dfls and DARKTOWN), P8RAT (aka GreetCake and HEAVYPOT), and FYAnti (aka DILLJUICE Stage 2) which in turn loads QuasarRAT. In November and December 2020, two public blog posts were published about this campaign. One month later, we observed new activities from the actor with an updated version of some of their implants designed to evade security products and make analysis harder for researchers.
