However, even though the criminals managed to get away with McArthur\u2019s devices, they didn\u2019t know that the keys they took were part of a <a href=\"https:\/\/www.youtube.com\/watch?v=ArLeGF3rK2I\" target=\"_blank\" rel=\"noopener\">multisig setup<\/a>. As a result, the burglars couldn\u2019t spend one satoshi, and McArthur\u2019s stack was left intact.<\/p>\n<p>\u201cYou have to diversify your security for your most important investments, it\u2019s extraordinarily important. And that\u2019s exactly what multisig is doing,\u201d McArthur <a href=\"https:\/\/www.youtube.com\/watch?v=mTUWC7AHhL0&amp;t=86s\" target=\"_blank\" rel=\"noopener\">said<\/a> while sharing his story on the By the Horns podcast. \u201cOtherwise you\u2019re generally talking about 10 to 15 years of your hard labor&#8230;and the possibility of that all being gone&#8230;you\u2019re not getting those years back. Don\u2019t skip on security.\u201d<\/p>\n<p>McArthur used a 2-of-3 multisig service from Casa, a bitcoin services company, in which he held the majority of the keys and had Casa function as a backup provider. The company was central to helping him deactivate the robbed key and switch his setup to restore complete control over his funds after the burglary.<\/p>\n<p>\u201cProvided that I purchase myself a new Ledger, deactivate that previous key, sync up my new key with Casa&#8230;I can get back to using my Ledger and my phone,\u201d he said. \u201cIt\u2019s an easy process, they walk you through every step of the way.\u201d<\/p>\n<p>Despite protecting against burglaries, <a href=\"https:\/\/www.youtube.com\/watch?v=ZQvCncdFMPo\" target=\"_blank\" rel=\"noopener\">multisigs<\/a> and physical separation of keys are essential to protect against another attack vector&nbsp;<em>\u2014<\/em>&nbsp;<a href=\"https:\/\/blog.keys.casa\/how-to-protect-your-bitcoin-from-5-wrench-attacks\/\" target=\"_blank\" rel=\"noopener\">$5 wrench attacks<\/a>.
