A recently leaked US ‘No Fly’ list with a million entries was allegedly posted on hacker forums. On January 26, a threat actor listed a dataset for sale that allegedly is the recently leaked ‘No Fly’ list. The exposed files contained more than 1.5 million entries with full names and birth dates of individuals denied boarding an aircraft and around 250,000 entries of selectees who must undergo additional security screening before flying. The ‘No Fly’ list is a small subset of the US government’s Terrorist Screening Database, which includes the personal information of identified or suspected terrorists. It is managed by the FBI’s Terrorist Screening Center.
