Quick answer

A ROB RUN decoder is used on another player’s Security System to obtain temporary access to the building. The owner can repair the system and lock you out again. Access is a window in which to act, not ownership of the whole property.

What a decoder does

QuestionConfirmed answer
Where is it used?On a rival base’s Security System
Is access permanent?No; the system can be repaired
What strengthens security?Fuses increase the attacker’s time and resource burden
Can allies be warned?Defense modules can alert allies during an attack
Is a fixed breach count published?Not in the official sources reviewed

Before committing a rare tool

Check the target’s displayed security information and the item in your inventory. Decide what you intend to do once inside and how to leave. Do not assume opening a building also opens every container, captures the plot or transfers vehicles. Those are different claims that need their own evidence.

The official FAQ says breach decoders are not simply bought off a shelf. It does not provide an exact recipe, exchange cost, loot location or drop probability. Community trading claims may be useful leads, but this guide does not turn them into a verified acquisition route.

Defending against a breach

Use fuses in the Security System and inspect your defense-module options. Make sure allies understand what they should do if an alert arrives. Since the owner can restore the security system, the ability to respond is part of defense planning.

The November 4 patch increased the stack size of decoders and some other items. It did not publish the old or new numerical limit, so there is no supported stack-size table to copy into this edition.

How many decoders do I need?

No universal count is verified. Inspect the current item and target rather than relying on a fixed number for every base.

Does a decoder make the base mine?

The confirmed function is temporary building access. It does not establish ownership transfer.

Where is the guaranteed decoder farm?

No such route is established by the official sources used here. Avoid spending resources on an unverified recipe.
