Ethereum account stolen
In Ethereum, all kinds of transfer and other transaction operations need to be completed by accounts. In the transaction platform, such as currency exchange transaction platform, each transaction needs to have a transaction initiation account and a transaction receiving account. Each account corresponds to an address, and the account name is the label of the address. Use a wallet to manage accounts. A wallet can contain multiple accounts. Of course, you can also create multiple wallets
According to several okex and okcoin users, their accounts were stolen, with losses ranging from tens of thousands to millions. According to preliminary statistics, nearly 10 users have reported losing about 600 bitcoins, worth about 20 million yuan
On September 1, some users said that they had 468 okcoin accounts, only 125 of them were left, 343 less. The user said that there is no need for any password or verification to transfer the okcoin contract account to the spot account. The developed currency to currency transaction has no depth at all and is easy to be used by the number stealing personnel. Okcoin does not provide corresponding protectionon September 16, another user transferred 30 BCC tokens stored in okex to okcoin, and on September 23, the account was invaded again, buying and selling between bitcoin, Leyte, Ethereum and RMB for many times, exhausting 30 BCCs and 27 bitcoins, trading nearly 1000 pieces in two hours, and the abnormal IP addresses were Russia and the Netherlands
"if the virtual currency property is changed into legal currency for cash withdrawal, the account is required to have real name authentication, so it is necessary to withdraw the profit in one stroke by knocking or exploding the position." Liu Chaoqun thinks that several problems of okex platform include: there is basically no trading volume of currency trading at ordinary times, and the trading volume suddenly increases a hundred times, so the platform does not do any risk control on this; There is no email or SMS verification for remote login; After the remote login reminder, immediately contact the platform, and the platform does not respond at the first time; The withdrawal speed of profit account is obviously abnormal, much higher than the normal speed
A: generally, there is only one account address, otherwise there will be an error! Blockchain itself is unique. If there are multiple account addresses on one node, it violates the fundamental principle of blockchain!
the private key must be well protected and should not be known to anyone except yourself
wallet is very important. If you want to use it, you should fully understand the choice.
