What is False flag?
Deliberately planting evidence, such as code, language or tools, that points investigators toward someone else.
A false flag is evidence planted to make an operation look like someone else's work: borrowed malware, foreign-language strings, copied infrastructure patterns or claims posted under another group's name.
False flags are why careful analysts weigh many independent lines of evidence and state confidence explicitly. A single striking clue, especially one that is easy to fake, should never carry an attribution on its own.
