This drops off Elites which are summoned by various items such as
Scorched Data Disc,
Rust-Covered Disc and
Large Storage Fragment. The easiest way to get one of these is to turn in the daily quest at Junkwatt Depot for
Recycling Requisition, which has a very high chance of dropping one.
You can also simply kill elites summoned by other people at
R33-DR when the
Data Anomaly quest is up in Rustbolt. This is repeatable regardless of whether or not you have turned in the daily quest.
As of writing this comment you can currently abandon the quest after summoning the elite and then pick it up from the item to summon the elites an infinite amount of times, which is very helpful if you're farming for the
Blueprint: Holographic Digitalization Relay, since the quest item is not consumed on use.
