Like so many idioms, the term false flag originated in a literal sense, eventually taking on a figurative sense. We will examine the definition of false flag, where the term came from and some examples of its use in sentences.
False flag describes an operation that is carried out by one entity or group, but is designed to look like it was executed by a different entity or group. For instance, a malware hacking that was carried out by a terrorist group but appears to have been perpetrated by a foreign government is a false flag. The term false flag is derived from a naval practice. In times past, a ship might fly a flag other than its own true flag in order to trick its way into an attack or to facilitate an escape. False flag may be used as a noun or as an adjective. The term false flag is often seen inside quotation marks, which means this is a relatively new term to most of the public.
