This tool allows you to steal funds from nodes that attempt to pay an invoice a second time after the first succeeds. Soon we will add the wormhole attack in it so that routing nodes can get more money by shortcuting other routing nodes in the middle. You can safely run this and sit back and watch your node get more sats than it was getting before. There's also a mode that doesn't steal in case you want to see if you could have stolen funds.

Paying an invoice a second time has to be a mistake most of the time. If thats the case you made a tool to steal sats from people who make this mistake? What im missing

Conceivably, this could be combined with an invoice replay attack in niche situations where the invoice is being presented by a 3rd party, but either the destination is validated, or the skimmer wants to be discrete.
If you're using an LNURL bridge for example, this would be reason to have a short TTL on your invoices.

I've done it when I get a payment that takes too long. I test out new lightning wallets all the time, and not all of them are very reliable. So when I try to pay an invoice, it often gets "stuck" for several minutes trying to pay without either failing or succeeding -- just "pending." When that happens I usually switch to a different wallet and try to pay the same invoice with that one. In other words, without making a mistake, I try to pay the same invoice twice. I did not consider that I can lose sats doing this but now I will take that into consideration.
