Hacking Bitcoin Wallet
Posted on by admin
Every year, thousands of users become victims of hacking attacks by voluntarily sending fraudsters $200 millions of dollars in cryptocurrency. Why does this happen and what are the possible. Jul 04, 2019 There are Basically two ways a hacker could hack someones bitcoin wallet to stealing bitcoins. He is either able to get the Bitcoin wallet password (Wallet key or private key) of a user or a group of users and then use it to transfer all the bitcoins from users wallet to his anonymous wallet. Or he could actually hack Bitcoin Exchange and steal all the bitcoins. Nevertheless, they all are vulnerable because, as you want to know how to hack a Bitcoin wallet, all you have to do is to somehow access that characters string which forms the private key. Most of the times, it’s the online services being responsible for storing private keys that get attacked. This method involves a program changing a wallet address you put in into one that belongs to crooks. You decide to transfer some kind of cryptocurrenty (whether it’s Bitcoin or Ethereum) to someone, copy their wallet address, paste it in your wallet and prepare to send the cryptocurrency.

Bitcoin is a very popular cryptocurrency that is stored in Bitcoin accounts, called wallets. These wallets are distinguished from one another using an “address” that plays the role of a username. Bitcoin addresses are actually a string ID that has between 26 and 35 alpha-numeric characters.
But hacking losses are a blip relative to the trillions of dollars kept in banks. While early Bitcoin wallet companies made people keep track of their own private keys—the secret 64. Let us see how exactly hackers are stealing thousands of bitcoins using Bitcoin hacks that work: 1) Hacking users Bitcoin wallet password (Stealing Private Key) Owning a Bitcoin wallet literally means owning a private cryptographic key (Blockchain Password) to unlock the wallet address of other users in order to send them Bitcoins.
This wallet can be opened by a private key so that can be used to authorize bitcoin transactions. If the user loses this private key, they lose their only method of accessing a wallet. In most cases, users are supplied with an automatically generated private key when they register an account, which they can change later on.
One of the most common practices to choose a Bitcoin wallet is via the “Brain Wallet” technique. Users can visit special sites or use special applications, sometimes embedded within Bitcoin wallet services, to enter a regular text-based passphrase. This passphrase is then converted using the SHA-256 hash algorithm into a 256-bit number that becomes the Bitcoin wallet’s private key. In case the user loses their private key, they can always reproduce it by converting their passphrase into a 256-bit number via the SHA-256 algorithm.
Now, three researchers have found out a rather simple way to crack the Bitcoin brain wallet passwords. The researchers have published a paper detailing the method, which they claim, is 2.5 times faster than previous techniques and incredibly cheap to perform.
White Ops security researcher Ryan Castellucci had demonstrated last summer at the DEFCON 23 security conference in Las Vegas, USA that it is easy for hackers to hack private bitcoin keys. He was joined by two more researchers from University College London to crack the bitcoin wallet password.
The three researchers used their technique against real-life Bitcoin wallets and managed to crack 18,000 passwords. Some of the passwords included silly passphrases like:
? say hello to my little friend Manual transfer switch for generator.
? to be or not to be
? party like it’s 1999
? yohohoandabottleofrum
? dudewheresmycar

The researcher also revealed that a potential hacker could use the basic Amazon EC2 account to check over 500,000 Bitcoin passwords per second. The researchers said that by renting a $1 EC2 server, an attacker would be able to check 17.9 billion password strings. To check a trillion passwords, it would cost the attacker only $55.86 (€49.63).
The conclusion of this research is that users should stay away from using common passphrases to generate Bitcoin private keys, and despite the complex cryptography utilities used to build Bitcoin, the service’s security can still be sabotaged by the maligned practices users employ when choosing passwords for online accounts.
The researchers have published their Speed Optimizations in Bitcoin Key Recovery Attacks research paper on International Association for Cryptologic Research website.
