Two popular games and a gaming platform developed by Asian companies were compromised following a series of successful supply-chain attacks. Malware used in the supply chain attacks is designed to check the region of the compromised machines before dropping the payload and, if it’s a Chinese or a Russian computer, it will automatically stop the infection process. The number of victims most likely is in the tens of thousands given the popularity of the hacked gaming platform and games in Thailand, Republic of the Philippines, and Taiwan.
