360 blockchain cloud mine
for example, bitcoin was invented by Zhongben Cong in 2009, and the total number of bitcoin was only 21 million. By participating in the proction of blocks and providing proof of work (POW), we can get the reward of bitcoin network. Mining is the process of packaging and confirming the transactions in the bitcoin system over a period of time, and then recording them on the block
if you need to know more about it, you can look at my account number; Let's discuss
what is moving bricks
when it comes to "moving bricks", you will think of migrant workers or various online jokes, but today we only discuss "moving bricks" in the blockchain market
to describe "moving bricks" in vernacular is to make profits by using the price difference between different exchanges. The same currency has different prices in different markets. Buy it in a cheaper place and sell it in a more expensive place. The middle price difference is your profit
for example, the price of bitcoin BTC is $4000 on exchange a and $4100 on exchange B. after a buys BTC, it can be sold to B and each one can earn $100. This process is called "moving bricks"
Recently, Vulcan team of 360 company found a series of high-risk security vulnerabilities in EOS, a blockchain platform. It is verified that some of the vulnerabilities can remotely execute arbitrary code on EOS nodes, that is, they can directly control and take over all nodes running on EOS through remote attacks
In the early morning of May 29, 360 reported this kind of vulnerability to EOS official for the first time, and assisted it to repair the security risks. The person in charge of the EOS network said that the EOS network will not be officially launched until these problems are fixed
EOS super node attack: the virtual currency transaction is completely controlled
in the attack, the attacker will construct and publish a smart contract containing malicious code, and the EOS super node will execute the malicious contract and trigger the security vulnerability. The attacker then uses the super node to pack the malicious contract into a new block, resulting in the remote control of all nodes in the network (alternative super node, exchange recharge withdrawal node, digital currency wallet server node, etc.)
because the system of the node has been completely controlled, the attacker can "do whatever he wants", such as stealing the key of the EOS super node and controlling the virtual currency transaction of the EOS network; Obtain other financial and privacy data in the participating node system of EOS network, such as digital currency in the exchange, user key stored in the wallet, key user information and privacy data, etc
What's more, an attacker can turn a node in the EOS network into a member of a botnet, launch a network attack, or become a free "miner" to extract other digital currency
