The well-known incident called the Great Czerka Datacrash concerned the Czerka Corporation and was caused by a freelance spy referred to as the Shroud. This occurred before the conquest of Makeb in the year 3638 BBY.
In the 2013 Digital Expansion, Rise of the Hutt Cartel, for the 2011 BioWare video game Star Wars: The Old Republic, the Codex entry for the Shroud referenced what became known as the Great Czerka Datacrash.
