[uncensored-r/Bitcoin] I was robbed on Blockchain wallet and not so sure how it happened.
The following post by cool1007 is being replicated because some comments within the post(but not the post itself) have been silently removed. The original post can be found(in censored form) at this link: np.reddit.com/ Bitcoin/comments/7cyb3e The original post's content was as follows:
Hi, I am not looking for people to trash me or talk smugly at me, I realized I made quite a few mistakes, probably the most important one is not being an expert in cryptocurrencies or a super tech savvy (or at least a decent one, heh). I am sharing this story to warn people so they can be smarter than me. Today I decided to enter my blockchain wallet and try to secure it even more because I planned to buy some more bitcoin. First grave mistake, I did not have 2FA enabled because it was not a big quantity I had (about $130 worth). I did not remember the URL address so I Googled it and clicked the first link that showed, it was an ad for blockchain.com (see image https://flic.kp/21uoHtN). The site looked legit, so I logged in my wallet and asked for email authorization. I checked my email, I got an email from blockchain.info asking me to authorize the login. Notice the screenshot https://flic.kp/21xaZpn , the IP the site says I am requesting the authorization. I am not using a static IP, it changes frequently and I did not know at that moment what my IP was. I click authorize and enter the site. Here, blockchain.info shows me a screen that they had received 2 authorization requests, one on the left side with the IP I showed you above, and the "current" request coming from a different IP (my real IP) on the right side. I was puzzled, but stupid as I am, did not think anything wrong with it, I authorized the entry. By the time I did that all my alarms fired off, closed the browser. Entirely. This time, I entered the site by typing the address blockchain.info (now that I remembered) and logged in. I received a new authorization email (from the same source) but this time it says it comes from a different IP (my real one, check image https://flic.kp/Zs2TVo). I hit authorize and entered to find I have an active transaction which sent all my wallet balance to 2 different wallets. I decided to research the IP from which the first authorization request came from, I saw it is an IP from Trinidad and Tobago :( ... so there you go, someone there pulled a scam on me, easy as pie. You can check the transaction here: https://blockchain.info/tx/1e93bb16f25c3209dd65357d8237594b0ac2ee2b6af056dcdbe0f35ddf717edd My heart stopped. You might think $130 is not much (my initial investment was like $50), but to me, it was a decent amount. I earn about $600 a month, I live in Ecuador, not in the first world. I work from home because I have Osteogenesis Imperfecta type III so I am confined to a wheelchair. Companies don't hire people that need help even to go to the bathroom. Anyways, that's it. The scam was very well done, I used to feel proud of being able to spot them miles away, but not this time. So, BE CAREFUL. Activate all your securities, double check URLs. If your instinct tells you something is wrong, LISTEN TO IT. I hope this helps someone else :(
I had previously swore off bitcoin after losing ~$15k in early 2018. I was a new inexperienced investotrader (i didnt even know the difference at the time) and saw what i thought was an opportunity of a lifetime to get on board with the future -> Invested heavily into GBTC early 2018 -> Instantly became a bagholder when it dropped -> it continued to drop with no end in sight -> held and prayed as long as i could then eventually cut my losses and moved on. Initially I blamed bitcoin for my loss and considered it a scam like an immature twat but now i know better. The only reason i lost money was because i made mistakes plain and simple. Currently i am loosing faith in the US dollar...and the US in general. The amount of money printed this year makes me want to fucking barf. My savings being robbed via some backhanded bullshit called "inflation" annoys me to no end. I have made some money on gold this year but was thinking last night about how closing my mind to crypto not only goes against my free market beliefs, but that cryptocurrency provides me a direct means of expressing "fuck the feds" via my wallet. I have a hard time simply googling this topic because of the widespread hate or bagholder promotion so starting here among supporters. Looking for some opinions on what you believe the most viable long term CCs are? Which ones have the most potential and why? I would really appreciate if you could recommend some educational videos or articles from what you consider a trustworthy source. Thanks
If you leave your coins on a Chinese exchange, the Chinese state may seize them
I know OKEX is incorporated in Malta/Europe, but the exchange's execs are in China. Even the one(!) guy apparently holding the key to sign withdrawals is in China, and under investigation there. Has he been forced to disclose his key to state actors by now? Consider OKEX compromised. That means: get everything you own off there, now. Though the majority of BTC miners may be Chinese, mind you that most buyers of crypto assets are--obviously--rich Westerners. An exchange like OKEX is worth many, many billions of USD$. In a financial war between the US and China, China could easily seize Binance/Huobi/OKEX and other exchanges under their territorial control, even ones incorporated in Malta if the execs are in Beijing. Get a real wallet, like Wasabi or even Bitcoin core or even Coinbase's dedicated wallet app, but ffs, get your coins off the exchanges. Exchanges can be seized by state powers, execs can be imprisoned, HQ's can be robbed, key holders can be abducted by terrorists, etc. etc. Not your keys, not your coins.
How do I prevent someone from stealing all my bitcoin at gunpoint?
If someone steals the cash I am carrying, it's only a fraction of my money. If they steal my credit card, I can call and block it, and whatever they purchase in the meantime is insured. What happens if someone makes me transfer him all of my bitcoin at gunpoint? How can I get it back at a later point. Has the system considered that possibility?
Storing your coins safely while not risking loss of keys
This was originally an answer to a question that was asked here, but OP deleted their post. This might help some newbies (especially the multisig edit at the end), so I want to make sure it's still accessible here. The original question was whether the Electrum wallet stores a Trezor's private key when using a passphrase. OP noticed that their Trezor wouldn't connect to their Electrum wallet when entering a different passphrase than they used when creating the wallet. Thus, OP (likely) assumed that the wallet stored the private key, as it somehow knew that a different private key was now used. Here is my original answer (with some modifications): IMPORTANT: I'm assuming here that you connected your Trezor by choosing the "hardware wallet" option in Electrum, rather than giving Electrum your 12/24 seed words. TL;DR: No, your coins are safe :) I'm assuming by passphrase) you mean the 25th (or 13th) word. When you have this feature enabled, a private key gets generated every time you enter a passphrase. When you enter the same passphrase you used to create the wallet, the wallet with your funds shows up. Whenever you enter something different, a different private key is generated on your Trezor. This allows you to have multiple different wallets, for example by choosing the passphrases "First Wallet", "Second Wallet", "Third Wallet", or a secret wallet with a secret passphrase. So whenever you enter a new passphrase when connecting your Trezor to Electrum, the Trezor will send a new public key to Electrum. Electrum will then derive addresses from this public key and check those for balances. It won't find any, as you used a new passphrase. EDIT: I just realized that you said your wallet doesn't connect to Electrum when you use a different passphrase. This is simply because Electrum doesn't receive the correct public key from the Trezor and therefore Electrum thinks it's a different wallet (which it is). When you enter the passphrase you used during creation of your wallet, the Trezor will send your actual public key to Electrum, which will then find addresses with balances, which it will show to you. EDIT (to clarify): Connecting your Trezor after creating the wallet is only necessary to send funds or verify addresses, as the public key is already stored in the wallet.dat. The only thing Electrum actually stores is the public key, which can only be used to look at your Bitcoin, not to move them. You might want to keep this public key a secret as well though, since it links all your funds to you. This is what Electrum stores in the wallet.dat file, which you can just encrypt by choosing a password for it. Well done using a passphrase by the way! Should someone get their hands on your Trezor, a sophisticated attacker can get the secret key off the device in 15 minutes. Using a passphrase makes this attack almost useless, as the both secret key AND the passphrase are needed to move your funds, and the passphrase is not stored on the device. A passphrase also allows you to hide funds from potential robbers that force you to unlock your wallet. You can do this by activating the passphrase feature and sending your funds to a wallet with a secret passphrase (do NOT lose this, as losing your passphrase renders your funds inaccessible). Afterwards, you can safely deactivate the passphrase feature, so the device doesn't even ask for one should you get robbed. Simply reactivate it when you need to access your funds. EDIT: Should you be worried that you might forget your passphrase, you should look into multisig wallets. Depending on how you set this up, you can make it more secure against theft and less likely for you to lose access to your funds. Say for example you get four wallets: two hardware wallets, a well-protected (airgapped) laptop with Electrum, and a secure mobile wallet that allows for multisig (like Fully Noded). You can then create a 2-of-4 multisig wallet that requires you to sign transactions with any two of these four wallets. The increase in security comes from the fact that an attacker now needs full access to two of your devices (or their stored private keys) at once. At the same time, the fact that you yourself now also need access to only half of your devices means that in the event of a total loss of one (or even two) of them, you can still move your funds to a new wallet. As long as you do regular checks (e.g. first day of each month), ensuring that you still have access to all your devices' stored private keys, you can always catch a loss of keys and fix this without losing funds (by creating a new multisig wallet and sending the funds there). This allows you to use a passphrase on your wallets without storing it anywhere physically or digitally. This would usually be very risky, as forgetting the passphrase would lead to a loss of funds, but this risk is now close to eliminated. (The following part was not in the original answer) Some IMPORTANT general secruity tips:
Consider including trusted friends and/or family members as co-signers for a multisig wallet. This ensures that it's not even possible for you alone to hand over funds to an attacker. Depending on your level of trust, you might want to make sure that your co-signers can't collaborate to steal your funds (if you include 3 people, create at least a 4-of-n multisig). You could also deliberately make it possible for all or even just some of your co-signers to move your funds (3 co-signers, 3(or less)-of-n multisig) to make sure your funds aren't lost should pass away unexpectedly.
Consider running your own full node and Electrum server (also check the alternatives), which you connect your Electrum wallet to. This ensures that you don't send your public key to anyone else. If someone knows your public key, they know how much BTC you own, making you a potential target.
Always encrypt your wallet.dat (or whatever you called your wallet file), even if it's a watch-only wallet. This protects your public key (see 1. for why you want that).
Create watch-only wallets: Use an airgapped) device to create a wallet with Electrum (make sure to back up the seed phrase) and export the public key. Then create a new watch-only wallet on another device (like your everyday laptop) with that public key to be able to check your funds. To create the initial wallet, you can also use any other hard- or software wallet that allows you to export the master public key.
Hide, or (when using a hardware wallet with a passphrase) even delete your watch-only wallets. Hiding your funds makes you less of a target. When using a hardware wallet, recreating the watch-only wallet is fast and simple, so you don't need to store it if you don't want to check your funds every day. Note that this approach doesn't help much when you don't use a passphrase, as an attacker will obviously check the passphrase-less wallet no matter what.
Keep some funds on your hardware wallet(s). If an attackers sees funds on the wallet(s), they might not force you to enter a passphrase or ask if you have any multisig wallets (lying under pressure is hard).
Hide all your wallets in different places. If someone sees that you have multiple wallets lying around, they might realize you have a multisig wallet.
Don't risk a robber getting (for example) two keys to your 2-of-4 multisig wallet and then racing them to move your funds with the other two keys when they leave. They're gonna come back and be pissed. If it comes to this, you need protection until the robber is caught. STAY SAFE!
The easiest way to solve a problem is to never have it. Don't make yourself a target. If nobody even suspects that you have a multisig (or any wallet at all), they're probably not gonna look for it.
Please correct any mistakes you find and I will edit my post. I will also gladly add more tips to the list. I will of course credit anyone who helps. Tip for devs who want something cool and important to work on: Make the creation and usage of multisig wallets as noob-friendly as possible. If someone expresses worries about losing access to their funds by forgetting the seed phrase, wallet pin, etc. (someone in my family actually brought this up to me), multisig wallets are the perfect solution as they add redundancy.
