Exploit the vulnerability of virtual currency network platform

1. For example, the game currency used in online games, in fact, is recharged with real currency, or the game reward (game equipment or level) you get for spending a lot of time and energy in the game. In a sense, it condenses your labor and forms the income of labor, so when others violate your virtual currency in the game, That is, it constitutes a crime
in the form of game fraud, game account theft, etc

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

On June 8, 360 exposed the high-risk vulnerability of EOS, which caused a lot of hot discussion among networks. In the early morning of June 2, Beijing time, EOS officially acknowledged to the 360 security team and offered a reward of US $30000, strongly calling on the security community to work together to ensure the continuous improvement of EOS software security

360 exposed EOS vulnerability, if exploited, can control every node and every server in the EOS network, not only take over the virtual currency, various transactions and applications in the network, but also take over all participating servers in the node. It can be said that if someone makes a malicious smart contract, all the digital currencies in it can be taken away directly

the attack of EOS vulnerability can spread among multiple nodes and super nodes at the speed of seconds. The continuous propagation from the control node to the generation of new blocks is a continuous and chain explosion action. It is likely to take over all nodes and complete the operation in 20 seconds

imagine that when the attacker has obtained the supreme authority in the entire EOS network, it is equivalent to mieba putting together all six cosmic protoliths, and can change rapidly in the universe and do whatever he likes

It was reported on May 29 that 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

the hidden dangers of blockchain network security need to be paid attention to

EOS is a new blockchain platform known as "blockchain 3.0". At present, its token market value is as high as 69 billion yuan, ranking fifth in the global market value

in the blockchain network and digital currency system, nodes, wallets, mines, exchanges and smart contracts all have many attack surfaces. 360 security team has found and exposed several serious security vulnerabilities for digital currency nodes, wallets, mines and smart contracts

this time, the 360 security team found a series of new security vulnerabilities in the smart contract virtual machine of EOS platform, which is a series of unprecedented security risks. No security researchers have found such problems before. This type of security problem not only affects EOS, but also may affect other types of blockchain platforms and virtual currency applications

360 expressed the hope that through the discovery and disclosure of this vulnerability, the blockchain instry and security peers will pay more attention to the security of such issues, and jointly enhance the security of the blockchain network

6. False, if there is such a situation, that person's account number will be directly blocked. You said that the devaluation of the currency and the inequality of the game environment will affect the income of the game, and the developers will not allow this situation.

8. Adoption simulator follows the game style of roblox simulator, with pixel game screen and square game area. It's just that the role you need to play this time will be a child or a parent. No matter which one, it's right to live

9. First of all, most games are invented by foreigners. So it's normal to use English. Well, if you can't understand it, it means one thing, that is, you haven't read good books before. This is a very bad phenomenon. Well, since you didn't read good books before. Now is the time to ecate your next generation. Study hard and make progress every day. If you think English is very important, then your children must apply for English class in the future. This way, it won't happen to your next generation like you.
