What is Private Lumina?⏎

Private Lumina provides for rapid function recognition, in the same way as the Hex-Rays Public Lumina feature does. However, Private Lumina keeps your in-house knowledge base available only to a group of users that you authorize. The Private Lumina feature comes in the form of add-ons to your IDA Pro subscriptions that can connect to a Private Lumina server that you operate yourself in your own infrastructure. All your IDA Pro instances that have the Private Lumina add-on enabled can connect to your own Private Lumina server.

Own your data

Keep your confidential information safe and have full ownership of the Private Lumina server that works with all IDA Pro instances with the Private Lumina add-on enabled.

Accelerate your work

Keep an in-house knowledge base of prior work and hit the ground running faster on ulterior projects.

Collect logs and stats

Hold control over your metadata through server logs and lc utility, which allows you to manage your server and collect statistics.

Keep it accurate

Maintain your Lumina database with ease and delete the metadata on the fly in IDA or do it via lc utility.

Improve your disassembly

You can automatically request metadata at the end of the analysis.

What is a Lumina server?

A Lumina server keeps track of metadata about some widely-recognizable functions, like their names, prototypes, or operand types. Additionally, Lumina allows you to "export" work that was previously done on another file to other projects. Hex-Rays offers both Public and Private Lumina servers. The Public Lumina maintained and operated by Hex-Rays, serves the entire IDA community. Alternatively, you can enable a self-hosted Private Lumina server.

How does Lumina work?

Your IDA instance exchanges function hash values and metadata with the Hex-Rays Lumina server, instead of entire byte patterns. When hash values provided by IDA match the Lumina knowledge base, your IDA instance downloads the function and applies it to the current IDA binary file database (IDB). Lumina is implemented as a hash-based lookup table, mapping byte patterns to metadata. For increased resilience, relocatable bits are masked out before hashing. The Lumina server performs lookups purely based on cryptographic digests, so (potentially sensitive) byte patterns are never transferred over the network.

Share with others

Any IDA Pro, IDA Home, or IDA Classroom user can send metadata to Hex-Rays' Public Lumina server. Any IDA Pro user with a Private Lumina add-on installed can send metadata to their Private Lumina server. A Lumina server stores the received metadata and makes it available to all IDA users connecting to that same Lumina server, either Private or Public.
