Some people are so proud that they just bought their first pieces of a Bitcoin and can’t wait to tell the world. Remember when teenagers could get VISA cards and when #MyFirstCreditCard was a thing on Instagram? Same thing here again. Since Bitcoin is a digital currency, what you get when you buy Bitcoin in an ATM is not a stack of bills, but rather a simple receipt containing – you guessed it – a private key, practically enough in the form of a QR-code. Bitcoin ATMs and social mediaīitcoin ATMs are fantastic and will hopefully make the average person more curious and less skeptical about Bitcoin. If you know of other search phrases, perhaps using other search engines than Google, that still work, please let us know! We would not be surprised if there still were wallet files to be found on the web that you could right-click and “save as.” 2. Nevertheless, why some people decided to upload their wallet files to their webpages in the first place is still an unsolved mystery we can just conclude that it happened a number of times.īy now in 2020, it seems that Google has finally decided to strike down on these ridiculously simple hacks, and to the best of our knowledge, such search phrases will no longer help you find wallet files. Typically, you never want to make your folder structures open on the web, and this was probably the result of misconfigured web servers. For the record, another popular search phrase was “inurl:’index of’ wallet.dat”, which would take you to webpages under construction and lists of all files in certain folders. It doesn’t matter that Bitcoin Core has always produced cryptographically safe keypairs, when users make them public online. Let us be redundantly clear: saving your wallet file in a public folder, unencrypted too, accessible in any browser, is a really bad idea. People were sloppy (or just plain stupid?), and more than one person decided this folder was the perfect place to store a backup of their Bitcoin wallet in.
At the time, all Dropbox accounts came with a public folder, so that everything you put there was exposed to the web, and much of it was picked up and indexed by Google. Until 2014 or so, it was fairly easy to find a decent amount of unencrypted Bitcoin Core wallet files that had unspent Bitcoin in them using a simple Google search phrase, such as “site: wallet.dat”.
Now on to the title list, in order of appearance: 1. The point here is that there isn’t, and will likely never be, enough computational power in the universe to bruteforce these, so unless we hadn’t just written out the private keys, you could never have hacked these public addresses. You will produce a 64 character hexadecimal string (256 bits or 32 bytes, if you will) such asīc1qsatm4dxhxe8a756xznh6c2p52cctxzqgwkx7lc

With a single line of code in Bash (“sudo apt-get install openssl” first, if necessary) There are thousands of articles describing the art of creating cryptographically safe private keys.

In other words, when your wallet software or your script outputs a new keypair, looking up that the resulting public addresses have been used before is unnecessary and is typically never done. an accidental keypair generation that has led to person A being able to control peron B’s coins. In fact, there is not a single known collision in the history of Bitcoin, i.e. Bitcoin wallet software uses pseudorandomness to create new keys, and until this day, it has worked out very well, which strongly suggests that these methods are good enough. And maybe as a source of inspiration for finding other exploitable weaknesses when it comes to human handling of private keys.Ī good private key should be perfectly random, and until we devise a machine that can output true randomness (if such a thing even exists), we are bound to rely on so-called pseudorandom functions to create private keys.

Consider this a list of how to not produce and use private keys. Here, we will list a couple of disasters that have led to compromised private keys and resulted in Bitcoin theft. Humans are not machines, however, and humans do make mistakes.
The vastness of possible private keys ensures that it is practically impossible to bruteforce one (or several) Bitcoin addresses. Print( "Private Key:", base58.A properly set up and used Bitcoin address is virtually impossible to hack.
