Bitcoin Theft: The Issue Persists

Arm yourself with Knowledge and Further Safeguard your Bitcoins

Bitcoin and cryptocurrencies at this point in time are not without their own sets of limitations and downsides. There have been numerous instances of individual wallets or entire exchanges being the victim of theft. Most large scale thefts occur at exchanges or online wallet services that store private keys of it’s users.

Crypto thieves hack their target online wallet service by finding a bug in its website or spreading malware to computers holding the private keys. One method in which bitcoins are stolen is transferring them from the victim’s btc address using a stolen private key to sign the transaction. If this key is stolen the thief can use it to transfer the coins from the compromised address to another address they select. Once this occurs the network has no way to identify the thief, block further transaction of those stolen coins, or have a way to return them to the owner.

Victims of the theft have attempted to identify the thief by sending “tagged” bitcoins to his accounts, using the public nature of bitcoin transactions to follow these moneys through the “blockchain” record of transfers.
