Every time I see news from Guotai Junan, I feel a deep sense of disconnection because during my student years, I hacked into their official website backend, infiltrated their internal network servers, and my impression was that they were a poorly technically equipped, obscure little company. I never expected them to be so powerful.
(Disclaimer: I did not cause any damage, did not take any information, and the statute of limitations has passed.)
Back then, I was still a student, young and ignorant, competitive, spending all night energy on researching technology, mingling in major hacker, red hat, and white hat forums. The atmosphere for technical exchange was much better than now, unlike now when people only dare to communicate privately, and one wrong move can lead to charges of "illegal intrusion into computer systems."
By chance, I obtained a "0day" vulnerability, using quotes because I didn't know if it was a 0day or a 123day. Then I used the universal key to try locks everywhere.
First, I scanned for SQL injection vulnerabilities, then exhaustively guessed the administrator password in the database, reverse-engineered weak passwords from ciphertext, and found the management backend entrance. In the backend, I found an upload interface to upload a web shell, upgraded to a more powerful shell, obtained a shell, escalated privileges, scanned the internal network, and used the 0day to obtain reverse shells from other internal servers, using them as a springboard to continue using the 0day key to poke around for more reverse shells.
What seems like child's play now was the environment of network security back then, combined with youth and competitiveness.
Then don't hold back, just ask, and also tell me the reason so I can correct your erroneous thoughts. If you keep it to yourself and don't say anything, I won't be able to correct your mistakes.
The case is solved. The reason for the Bitcoin crash has been found. $BTC The U.S. bombed Iran's nuclear facilities, which were not nuclear weapons but nuclear power plants. Iran has been using nuclear power to mine Bitcoin. After the U.S. bombed three of Iran's nuclear facilities, the total Bitcoin network hash rate dropped from 1000 EH/s to 700 EH/s. The overall Bitcoin network hash rate decreased, while the unit block output remained unchanged, leading to a reduction in mining costs and consequently a decline in Bitcoin prices. $BTC
Instead of shouting from a distance, it's better to sit down and talk.
On May 24, the Cyberspace Administration, in conjunction with the Financial Management Bureau, carried out a special rectification activity targeting content related to cryptocurrencies and banned a number of online accounts that mentioned cryptocurrencies as negative examples.
On May 28, the International Monetary Research Institute of Renmin University of China published an article titled "Reasons for Bitcoin as a Reserve Currency"
The reason for the weekend crash may be this: yesterday (May 30), Trump posted on Truth Social
Trump: "Some time ago, we imposed tariffs on China, which almost destroyed China. I softened my stance and quickly reconciled with China, but now China is not being honest, and I regret it."
Google Translate is as follows:
Two weeks ago, China was in serious economic danger! The very high tariffs I set made it almost impossible for China to export to the U.S. market, which is the largest market in the world. We actually severed ties with China, which is devastating for them. Many factories have closed, and to say the least, there is 'public discontent boiling over.' I see what is happening, and I don't like it, not for us but for them. I reached a quick agreement with China to save them from what I thought would be a very bad situation, and I didn’t want to see that happen. Thanks to that agreement, everything stabilized quickly, and China returned to normal business. Everyone was happy! This is good news!!! The bad news is that China, perhaps not surprisingly to some, completely violated the agreement we had. Never mind, kind sir!
You can make money in the RWA track, but don't truly believe it.
The concept of RWA has been hot since the ICO era in 2017, and every bull market sees VCs bringing out coins. As retail investors, we can profit from trading coins based on the RWA hype, potentially gaining tenfold, hundredfold, or thousandfold returns, but don't truly believe it; the bull market has ended and everything will go to zero. The revolutionary significance of blockchain technology lies in constructing a trust and value system that does not rely on centralized authority—namely, 'decentralized value consensus.' For example, although BTC is developed by a centralized team, its value is not promised or anchored to any specific asset by any centralized institution. Its value is completely 'minted' by the consensus of global participants. This is the core of blockchain technology in creating on-chain value.
API Quantitative Trading Open Source Library CCXT Steals User Referral Commission Fees
The CCXT open-source library for API trading replaced the inviter ID and stole user referral commission fees. In fact, this issue has always existed; it just went unnoticed. The last time it was exposed was in April 2022, and I wrote the solution at the end of the post. Open source does not mean secure, as 99% of developers do not review the source code of open-source libraries; developers like @sunlc_crypto are just a minority. There have been many security incidents in the history of the cryptocurrency world caused by poisoned open-source libraries/supply chain attacks. 1. April 2024: @evilcos It was revealed that an open-source quantitative system for Solana had a backdoor for stealing user API private keys.
The so-called altcoin season is a myth of wealth creation triggered by the surge in Bitcoin, attracting outside funds that are unwilling to buy Bitcoin at high prices. This leads to funds flowing into altcoins, which is referred to as the altcoin season. However, currently, with Bitcoin's surge, there is a quiet atmosphere within the community, indicating that no one has become wealthy as a result. The wealth effect has not emerged, and currently, the only entity that can break out is Binance Alpha. However, Binance Alpha is just a minor gain, and it cannot create a wealth myth. Therefore, there is temporarily no altcoin season.
This time, with Trump's issuance of currency, I made a big profit. But don't feel bad yet, because I exchanged ETH for SOL, and my losses far outweigh my gains. Well, now you can start laughing.
Trump Shortens Solana Just to Buy ETH at a Low Price
ETH and Solana are in competition. Trump launched a meme coin on Solana, creating a wealth effect that siphoned funds into Solana. The Sol/ETH exchange rate rose from 0.062 to 0.093, causing ETH to plummet. Then, Trump bought 14,403 ETH at a low price during the WLFI, and subsequently released a wife coin on Solana without restraint, making everyone realize how absurd the meme boom on Solana was, leading to a crash in Solana and a recovery in ETH prices. This move by Trump not only promoted the healthy development of the web3 industry but also allowed him to make a significant profit before taking office.
User detained after demanding repayment from exchange owner
The exchange cannot withdraw funds, and the user was detained after unsuccessfully demanding repayment from the exchange owner, Huang Tianwei. Huang Tianwei is the owner of AEX Anyin Exchange (Bit Era), which banned users from withdrawing funds in 2022, then deleted user asset data, and finally closed the platform website, going missing to this day, and has not compensated users. #AEX #安银 #黄天威
Is it possible that we are actually in a bear market, that the price of Bitcoin has not risen, but rather that fiat currencies are collectively depreciating, with governments printing money to dilute the cash in people's hands, and keen capital is flocking into Bitcoin for hedging.
The rumor in the group was that the decline was related to the new Money Laundering Law.
I don’t agree with this view. Let’s first take a look at the rumors that are circulating wildly in the group. See the picture below.
I will talk about what I think are the reasons for the decline later. First of all, this popular statement and the understanding of the (Anti-Money Laundering Law) are both wrong. First of all, the (Anti-Money Laundering Law) was promulgated on November 8, which was a month ago. Even if it had an impact on the currency market, it would have been reflected in the price a month ago. And I think the new (Anti-Money Laundering Law) has no impact on the currency market, because on September 4, 2017, the policy required that virtual currency exchanges be registered and operated in China, so all exchanges went overseas, registered overseas, and operated in China.
First Exposure: All Chat Records of dex's Founder Roy Threatening Me
I originally didn't want to share this, but I am very worried that Roy might take extreme actions. After careful consideration, I decided to post this so that once it becomes widely known, Roy may have some reservations before taking action, thus giving up on extreme behavior. Consider it a way for me to protect myself. For detailed chat records, see the second image below.
