  • One threat actor in January 2021 offered real-time data for casino gaming, lottery and stocks on a popular forum used by Chinese cybercriminals. The data allegedly originated from big data sources of the two most popular mobile network operators in China.
  • Another threat actor in February 2021 offered website and application crawler data collection services on a Chinese-language cybercrime marketplace. The threat actor claimed access to insider channels of Chinese mobile operators for data collection purposes.
  • In early March, a threat actor on a marketplace offered 10,000 user records tied to a parenting application. The offering was described as big data from an undisclosed mobile operator or operators.
  • In late March, yet another threat actor offered big data that included commercial databases of Canadian and U.S. businesses and investors, a hacked Twitter database, and information on Canadian and U.S. citizens.
