Amid the cascade of US sanctions imposed Thursday on Russian cybersecurity companies and officials alleged to be operating on behalf of the Kremlin's intelligence services, one company stood out: the Fresh Air Farm House in Karachi, Pakistan.

The Farm House, whose Facebook page shows a waterpark-equipped holiday rental, is run by 34-year-old Mohsin Raza, one of two founders of an online fake ID business that prosecutors say helped Russian operatives get a toehold in the United States.
