Small Ferengi vessel whose crew boarded and plundered Enterprise NX-01 in 2151 without ever revealing the name of their species.
In 2151 a small Ferengi ship with a crew of four raided Enterprise. Starfleet had no record of the species, and the intruders never gave their name, so the encounter left humans unaware of who they had met.
In Acquisition, the Ferengi knocked out the crew with an anaesthetic gas, docked with Enterprise and began plundering it in search of a vault. Tucker, who had escaped the gas, worked with Archer to trick them with a fake vault, while T'Pol set the raiders against one another, and they left without their loot.
