Level Seven Crew, also referred to as Level Seven, was a hacker group active in the 1990s. Public reporting tied the group to the defacement of a website associated with the U.S. Embassy in China, and one account described it as a 13-member group. Beyond that attribution, high-confidence detail on its membership, origin, sustained operational history, targeting patterns, tooling, or broader campaign activity is not currently available. The group is primarily documented in historical listings of 1990s hacking groups rather than in detailed technical or intelligence reporting.
