In July 2017, the Ethereum wallet Parity was stolen. Hackers exploited its multi-signature vulnerability and stole 150,000 Ethereum. In November 2017, the Parity wallet had a bug again, and Ethereum assets worth hundreds of millions of dollars were frozen.
In January 2018, hackers transferred $400,000 worth of cryptocurrency from the BlackWallet wallet through a phishing website.
In April 2018, Myetherwallet (MEW) suffered a DNS hijacking attack by hackers, causing a user to lose more than 85 ETH, worth nearly US$60,000.
Similar thefts are happening all the time. If you lose your wallet, you still have a chance to get it back. But once your digital wallet is stolen, the chances of getting it back are slim. Blockchain is decentralized, and we can only find out which account our stolen digital currency was transferred to, but we cannot know the true identity of the stolen account. So the uncle is powerless.
In 2017, an organization called "Large Bitcoin Collider" organized hackers to brute force Bitcoin hardware wallets.
The name Large Bitcoin Collider is taken directly from the name of the Large Hadron Collider at the European Organization for Nuclear Research, which means using powerful computing power to guess the wallet key.#钱包
#数字资产找回The organization calls the cracking process "treasure hunting": once successful, the bitcoins in the wallet will be shared by the participants.
In nearly eight months of attempts, Large Bitcoin Collider generated 300 trillion keys, of which the keys of more than a dozen wallets were "guessed correctly", the wallets were opened, and three of the wallets contained Bitcoin.
In the future, if quantum computers appear, it may only take 8 hours to generate 300 billion keys. Just thinking about what might happen is chilling.
According to industry professionals, most of the digital currency wallets based on mobile platforms in China are not difficult to crack. As the wallet craze rises, more and more manufacturers are joining the battle, but their understanding of security is often inadequate, resulting in many security risks for wallets.
