Judging by the black Starfleet uniforms, I am going with the bad guys definitely being Section 31.
quote: Good article on this theory.
In the Star Trek fictional universe, Section 31 is an autonomous intelligence and defense organization. It is presented as a special security operation, manned by Federation citizens, that is not subject to the normal constraints of Starfleet ethical protocols. The organization appears, or is mentioned, across eight episodes of Star Trek: Deep Space Nine and Star Trek: Enterprise.
In the previews they say "He was one of our top agents". Not officers. So that is a hint, plus the all black. It's like a Star Fleet Coup.
