If you are using a Mk3 through the Q and didn't use a lot of dice rolls in generating your keys, consider it compromised and move to any quick location you can find. If you have another wallet without a coldcard, send it there, if you have a trusted exchange send it there temporarily, if you can create a quick software wallet send it there. Make sure all the normal process and backups are done carefully during this and then prepare for a better multisig setup for your replacement. My tools i used with a couple of people and for myself when i couldn't remember which software i set up one of my CC keys with: - connect CC to sparrow, import and it will find any and all related keys and balances. You can send from there to any new keys or non CC keys you have - generate a new key or hell if you are limited just send it to a good exchange like river to get it out of harms way as quick as you can. You can get a better setup after you get it out of immediate danger
