Strategic information operations (e.g. disinformation, political propaganda, and other forms of online manipulation) are critical concerns for researchers in social cyber security.

This study analyzes patterns of spoofing and astroturfing on YouTube regarding narratives about the White Helmets, a Syrian civil volunteer organization active in the long armed conflict in the country.
