Spider-Man fights the Hand ninjas in Spider-Man: Brand New Day.
The Hand is a fictional criminal and mystical organization from Marvel Comics. The group is especially associated with Marvel's street-level heroes and appeared prominently in Marvel's Netflix television series, including Daredevil and The Defenders.
In Brand New Day, Peter Parker battles Hand ninjas while protecting New York City. The film's writers used the group to reinforce the movie's street-level crime focus rather than relying only on world-ending threats. The Hand is described as having been leaderless since its last MCU appearance before the events of the film.
The Ten Rings is another MCU organization, associated with Shang-Chi and the Legend of the Ten Rings. The Foot Clan belongs to Teenage Mutant Ninja Turtles, and the League of Shadows is associated with Batman. None of those groups is the answer here.
