Taiwan is regularly targeted by cyberattacks from multiple sources due to its geopolitical situation. Recently, we observed cyberattacks targeting companies in Taiwan, including those in manufacturing, healthcare, information technology, and other sectors. The attacks involved phishing emails with identifiable characteristics, along with the distribution of multiple executable files. Among these attacks, Smokeloader's features are separated into multiple modules and AndeLoader delivers infostealer with Microsoft Office documents. Once the attacks succeed, the companies will be exposed to the risk of backdoor infections and data exfiltration. In this presentation, we will thoroughly reveal the attack chain and uncover the techniques employed during the attack.
