Background

  • Lang, a New Jersey resident and Chinese citizen, was employed as a financial analyst by Sujitech/Mask Network from 2022 to April 2025.
  • Lang was promoted to Regional Managing Director in March 2024 and allegedly terminated in April 2025.
  • Counterclaimants Yan and Sujitech allege Lang stole 1,545,154 USDT from Sujitech's Binance account and related assets, plus downloaded files and personal property theft.
  • Bybit allegedly holds the 1,545,154 USDT and agreed to a temporary freeze for 7 days to aid investigation.
  • Counterclaimants filed a motion for a preliminary injunction on August 4, 2025, seeking asset recovery, disgorgement, transfer of property to Yan, and deletion of downloaded files.
  • District Court denies the motion, finding no clear showing of irreparable harm and not addressing remaining factors.
