Bitcoin continues to hover above 29k overnight.
Under the superficial boredom, all kinds of dogs are undercurrents.
A Twitter big V was replaced by @Pauly0x, with 150,000 Twitter fans. A few days ago, a local dog called Pond0x was launched, and it went online and shouted "the next PEPE". The fans rushed with ether, unexpectedly There was a bug in the contract code, which wiped out all the funds of Chongtugou, and it was left dumbfounded and full of feathers. [1]
The bug in the contract code is that the transfer function in the following contract code allows anyone to transfer money from any address: [2]
Figure: transfer code
Here, the project side showed off a bit, and built an address conversion function \_brutalized, which seems to be to get a pseudo-random address from the original address, but unfortunately, he obviously got the working principle of Ethereum wrong:
Figure: "pseudo-random" code
The function of the gas operator in the EVM is not to give a non-deterministic gas cost, but to give the gas remaining so far. This function allows the attacker to control the calculation result at will by controlling the given gas, so as to easily wipe out the balance in any currency-holding address.
To say that the real name of this big V is said to be Jeremy Cahen, he is also well-known in the local dog circle. The imitations of CryptoPhunks and NotLarvaLabs back then came from him.
In addition, in the first half of this year (2023), probably in May, he did a "social experiment" similar to "I am Qin Shihuang, send money": directly released the Ethereum address on Twitter (yougetnothing. eth), claiming to send money (Ethereum) at will, and to make it ugly, will not promise any returns. The result of the experiment is that this tweet was viewed more than 1.2 million times in one day, and nearly 600 ETH and more than 1 million US dollars were sent to the money receiving address! [3]
This time after Pond0x made a fuss, this Jeremy Cahen still laughed at the fans who lost their money on Twitter, saying that this is not a bug (defect), this is a feature (feature), this experiment is to verify your greed , to teach you a lesson.
I have seen an arrogant project party, but I have never seen such an arrogant project party. An experiment of 2.2 million US dollars has to be said to be expensive, but it does not seem to be a big money in the currency circle where tens of millions of dollars are wiped out. No matter how big or small the money is, if it falls on a loss-making person, it will cause blood in the heart at the slightest, and the mountain will be overwhelming at the worst.
Some tuition fees are simply too expensive. Stock up on big pies, and pay as little as possible for Tugou's tuition.
