Millions of ETH has been stolen by "Blockchain bandit"
We all know that blockchain is very secure and your private key plays a very important part in securing your funds on the blockchain. Remember, not your keys, not your funds.
The probability of someone guessing a randomly generated ETH key is 1/2^256. That is 1 in 2 to the power of 256. In words, it would be one in one hundred and fifteen quattuorvigintillion. That sounds like a made up word!
The problem here lies with the way the private keys are generated. Consider the following private key:
0x0000000000000000000000000000000000000000000000000000000000000001
It doesn't look very secure, right? This is a valid private key, you can import this into My ether wallet to check it out:
These are the type of private keys "blockchain bandits" are targeting. They monitor these addresses and any funds transferred into them will be transferred out very quickly. It is very interesting the note that the researchers tested this by transferring some ETH into one of these compromised addresses and watched as multiple "blockchain bandits" fought over themselves to try and steal the funds! Amazing, if only those people used their talents for good!
