According to Coin World News, on July 9, Corey Wilton, CEO of Mirai Labs, recently revealed a large-scale "phone farm" located near Ho Chi Minh City, which has approximately 30,000 smartphones dedicated to manipulating cryptocurrency airdrop activities. These devices are equipped with independent SIM cards and device fingerprints, allowing them to spoof IP addresses, making them difficult to detect. The main business of this "farm" is to manufacture and sell DIY phone farm equipment, producing over 1,000 dedicated phones each week, which are packaged into "farm boxes" of about 20 phones each and sold to international customers. These devices are used to fake user activity and seize reward tokens originally intended for genuine early users.
