Foresight News reports that Yu Xian, the founder of Slow Fog, shared a report from Blue Dot Network stating that the official driver provided by Shenzhen printer company Tian Sheng was found to carry backdoor code, capable of hijacking wallet addresses in users' clipboard and replacing them with the attacker's address. Data shows that hackers have stolen a total of 9.3 bitcoins through this backdoor program. The infection occurred because Tian Sheng used USB drives to transfer these drivers, which were then uploaded to a cloud storage for global users to download after being infected.
