Payments seem to be in Ethereum, based on the description of the "Immunefi vault platform":
> This project utilizes a decentralized vault for their bounty rewards to ensure trust by showing that they have the collateral to cover their bounties. Payments are processed directly on-chain inside the Immunefi webapp.
Top payment so far is 3 payments of about 8,500 USD to the same recipient. The maximum claimed achievable payment is 1.1m USD.
It does at least imply that they've set aside magic beans to pay researchers, and that someone is being paid from the bean fund, for whatever that's worth.

An interesting side-effect is that you can view payments from the public vault for each project, for example:
