What a mess. Unfortunately this Trezor address leak will directly lead to an increase in targeted social engineering and potentially wrench attacks. Here are my recommendations for what to do if you were in this breach (or just want to protect yourself against the result of these breaches in the future). Social engineering protection Scammers will use the combination of having your personal information to both target you (phone, email) and convince you that they are legit (using your name and potentially home address as proof that they know you and are here to help). They will contact you via phone or email with targeted lies meant to scare you into talking to them and taking the actions they want you to, in the name of protecting your bitcoin. Ignore any communication from "Trezor" that doesn't come from their official domains (the @Trezor handle, are the main ones I know of). You should also ignore communication from "Google" or "Apple" pretending like your email is compromised. They trick you into giving them your email credentials, and then once inside your inbox they can do all manner of things to trick you without Google's typical filters stopping them. Generally a company's support team will never call you on the phone without you contacting them. If they reach out proactively and are trying to get you to take any action to "remain safe" - refuse. Social engineers steal much more money on a regular basis than physical attackers. Most people worry about physical attack more because it sounds scarier, but the bigger risk of actual funds loss is social engineering. Get your suspicion antennae up. Phishing Phishing has a lot of overlap with social engineering. The main difference in my mind is that phishers put in less effort than social engineers. Social engineers may use phishing tools to help them. Phishers are just putting their nets out and trying to get you to make a mistake. Be very suspicious of emails directing you to go to Trezor's website or download a new Trezor app. Triple check the URL for Trezor or any hardware wallet website that you visit. Even if you Google Trezor, there are fake Trezor phishing apps running Google ads that will tell you to type in your seed phrase and then steal your money. Be very careful when downloading or using new wallet apps that you are getting the right one. Wrench attacks The one everyone worries about the most, even though it's the least common. Unfortunately since this breach includes physical addresses, it's possible we will see some wrench attack attempts come from it. Unless you are going to move, the best you can do is try to deter attackers and make sure that if it happens, they can't steal all your money. Distribute your keys and use a multisig to ensure that you don't have enough keys to spend bitcoin at your house. Then consider keeping a small-ish amount of BTC in a single sig wallet that you are willing to give up to make someone go away. We don't recommend the type of duress wallet that uses the same device/software as your main wallet, but when you type in a different PIN it brings up the fake wallet. It's too hard to remember the duress PIN when someone is beating you up, and too easy to give in when they ask you for more after you pay them from the duress wallet. You need to make it so you truly can't send them all your money. Casa recently built Guardian Mode to help protect against social engineering and wrench attacks. It requires the Casa key to sign for all transactions you send. We do a video verification call to make sure you are not being tricked or under duress before signing with our key. Available to Premium+ Casa members. You can also check out an old post we did about physical home security, which unfortunately we have to reshare every year or two: Very sorry to all the people who were caught up in this. Rough few weeks for bitcoin security. Reach out to us if you need assistance on any of these points.
