🚨 Case Review | MetaMask Phishing Attack Leads to User Loss of $850,000
📌 Incident Overview
In September 2024, a MetaMask user clicked on a fake DeFi airdrop link and signed a malicious transaction on a phishing site, resulting in the loss of $850,000 in assets within 2 minutes.
🔍 Vulnerability Analysis
Traditional Cybersecurity: The attack exploited a 'Cross-Site Scripting' (XSS) vulnerability, allowing malicious scripts to steal users' wallet permissions.
Social Engineering: The fake interface of a well-known DeFi project induced users to take action.
Browser Extension Risks: Malicious plugins disguised as compliance tools altered transaction content.
🛡️ Our Recommendations:
1. Technical Measures
Deploy strict content security policies for front-end pages.
Use Subresource Integrity checks to prevent third-party scripts from being tampered with.
Conduct security audits on browser plugins.
2. User Education
Mandate employee participation in social engineering defense training.
Establish a phishing attack simulation testing mechanism.
Use multi-signature wallets to manage large assets.
3. Monitoring System
Deploy 24-hour on-chain anomaly transaction monitoring.
Establish a real-time warning system for malicious addresses.
💡 Key Insight
Web3 security must build a multidimensional defense system from the front end to the blockchain, and from technology to personnel, as traditional cybersecurity attacks rapidly infiltrate the Web3 domain.

The frequent hacker attacks on exchanges highlight the importance of wallet security. Exchanges are usually the concentration of funds and user information, and are easily targeted by hackers. Regarding the security of wallets, the following points are particularly critical:
1. Cold wallets and hot wallets: Cold wallets (offline wallets) are safer and less vulnerable to remote attacks. Hot wallets are less secure because they are connected to the Internet. Exchanges and users should give priority to using cold wallets to store most assets.
2. Multi-signature: Multi-signature technology requires multiple keys to verify transactions. Even if hackers steal some keys, they still cannot control the wallet, which enhances security.
3. Hardware wallets: Hardware wallets store private keys through physical devices to prevent network attacks and are a safer way to manage assets.
4. Security audits and repairs: Exchanges should conduct security audits regularly, repair potential vulnerabilities in a timely manner, and ensure system security.
5. User education: Strengthen users' security awareness, remind them not to disclose private keys, enable two-step verification and other measures to improve the security of personal wallets.
6. Compliance and insurance: Some exchanges have introduced insurance mechanisms to ensure asset security and strengthen cooperation with regulators.

In short, wallet security requires efforts from all parties. Cold wallets, hardware wallets, and multi-signatures can effectively reduce risks. Exchanges and users should jointly improve their safety awareness.

Recently, a case involving a massive cryptocurrency theft has attracted widespread attention. A 22-year-old Tunisian woman, Maysa Jabali, was arrested in Miami, accused of stealing $850,000 worth of Trump Coin cryptocurrency from her ex-boyfriend, Anthony Bravo. After their breakup, Jabali allegedly transferred funds from Bravo's crypto wallet and made unauthorized purchases using his credit card.

Because Jabali's identity was not registered, the U.S. Immigration and Customs Enforcement (ICE) detained her, raising concerns that she could be deported back to Tunisia before her trial. Jabali has currently pleaded not guilty, and her lawyer remains hopeful that she can stay in the U.S. to face the charges. This case has become quite complex due to the high amount of cryptocurrency involved, along with Jabali's immigration status.

On the SOL chain, there is a unique presence, Co nan with the last digits BQt, which is the only Dogecoin in the Trump concept. Trump personally awarded it the title of hero dog, praising it as the strongest dog on earth, making its special background quite eye-catching. The community behind it is highly active, continually building and deeply rooted in consensus. The development team is experienced and dedicated, having previously created two hundred-fold coins, showcasing potential in every aspect. This project is worth keeping an eye on!

Panic Alert: Experts Predict Bitcoin Could Plunge to $70,000? ETF Sell-off Hits

1. Market Shock: Bitcoin May Plunge to $70,000
Recently, BitMEX's big shot Arthur Hayes made a bold statement, saying Bitcoin might crash to $70,000. As soon as this was said, the cryptocurrency market erupted.

2. Big Players Making Moves: Hedge Funds Selling ETFs, Preparing to Flee
Hayes also revealed that those large hedge funds are busy selling Bitcoin ETFs in the U.S., planning to withdraw. They had previously played a good arbitrage game, buying ETFs while shorting in the futures market, ensuring profits without losses. But now that Bitcoin's price is unstable, they feel the risk has increased and have started selling ETFs, covering futures, and preparing to lock in profits and leave.

3. The Truth Behind the Arbitrage Game: Basis Trading
Hayes mentioned that this arbitrage game has a technical term called “basis trading,” which relies on the price difference between spot and futures to make money. However, when Bitcoin prices drop, these funds panic and start selling ETFs to hedge. This causes ETF prices to plummet, increasing selling pressure in the futures market, making it easier for Bitcoin to fall, resulting in a vicious cycle.

4. Market Reaction is Intense: Bitcoin Prices Fluctuate Wildly, ETF Funds Flow Out Frenziedly
The market's reaction to the expected Bitcoin crash has been extremely intense. In just one day, Bitcoin's price dropped by 5%, hitting a low of $91,000. Although there was a slight rebound on February 25, the overall trend still appeared weak. The ETF market is also in dire straits; on February 24, the outflow of funds from 11 spot ETFs reached $517 million, setting a new seven-week high. Funds have been flowing out for five consecutive days, with major fund giants like BlackRock and Fidelity suffering heavy losses.

Currently, the market is turbulent; walking alone is lonely. Follow me for daily potential spot layouts and bull market strategy layouts.

In the past few days, $PNUT has been crazy about trading, finally reducing the cost from around 0.5 to 0.4, hoping to make some money and leave 🙈

Yesterday, I mentioned my account login issue, and a bunch of people said I haven't seen much of the world, that re-logging in is not scary; what's scary is logging in from a different location. Previously, when I re-logged in, it was always a direct login, and it wouldn't prompt for a different location login at all. The different location login clearly means I was kicked out...
I also saw someone say that Binance always goes offline during major drops, but never goes offline during sideways movements or major rises; I don't know, and I don't dare to ask 🌝
#钱包安全 #钱包的自白：2024我都经历了什么?

For something like #钱包安全 that requires people to spend money to receive an airdrop, first curse at it, then retail investors can choose whether to participate or not. There is some risk, but it's not high, after all, it only gives this little something after three months. Those with spare money can give it a try, but I might not participate as my family is not wealthy and has no surplus.

Is it too late to enter the cryptocurrency circle now?

BTC has a history of 15 years, and there are only two waves of really large multiples, one in 2013, from 10 to 1000, and one in 2017 from 300 to 19000.

What is incredible is that they all happened within a year, that is, one year after the halving.

You can compare the housing prices at the end of 2017, when the BTC price was 19000. Now BTC is just over 40000, and the increase is not even as good as the housing price.

BTC is an old friend of everyone, and it is also a new thing, because people's cognition is gradually improving. Just like when the Internet first came out, everyone said it was an Internet scam and an Internet bubble. Most people only thought about investing when their lives were surrounded by the Internet and they found that they could not live without the Internet. At that time, the stock price had already risen to the sky, just like Apple's 3 trillion market value.

How many BTC users are there? Less than 50 million, which is not worth mentioning compared with Apple's billions of users. But less than 50 million users have created a market value of nearly 1 trillion, which just shows that there is still room for ten or a hundred times in the future.
So it is never too late to enter the cryptocurrency circle, as long as you are earlier than your neighbors.

If you don't even understand what the crypto world is, what you're doing in it, and the risks you might encounter when cashing out, then you should definitely not step into this murky water. The crypto world is not a charity; it won't go easy on you just because you are a novice or have a high education. Experienced players all know that what I keep talking about here is risk, risk, and more risk! Don't wait until you're trapped before regretting not heeding the advice.

Today we need to talk about the matter of safely cashing out. Those so-called tutorials online, nine out of ten don't hit the point, resulting in a bunch of people blindly following the big shots, and in the end, they are harvested by those unscrupulous U merchants, with some people even being charged a 20% service fee. This is simply brazenly harvesting the leeks!

Remember, never accept U at a different price, whether it's a drop or a rise, it's not acceptable. If the drop is too much, do you think you're safe? Wrong! That money could still be dirty. If the rise is too much, then there's no need to say more; it must be black money, a thousand percent.

Don't touch cash transactions off-exchange; in the domestic market, this is a minefield, and one careless move could get you in trouble. Moreover, why should you trust that trading party? There’s a good chance you’ll end up losing both your money and your assets.

You have to understand that money can also be clean or dirty. Real clean money must come from places like credit cards or online loans, and it has to be deposited for seven or eight days. Other sources carry terrifying risks.

So, is there a safe way to cash out? Of course, but don't expect it to be convenient, safe, and free at the same time; that's impossible. Cashing out must follow principles, with fewer transactions and compliant trading parties.

I will share two relatively safe methods with you:

The first one is C2C at exchanges. This requires waiting, and the order completion rate may not be high, but you need to find a merchant who has opened a shield and communicate with them in advance; in case of card freezing, compensation must be paid.

The second one is to apply for a foreign currency card. This requires going to Hong Kong to the bank to apply for a foreign currency card that supports US dollars, and then converting USDT to US dollars and then to RMB. Although it’s a bit troublesome, it is relatively safe.

Remember, don’t always think about taking shortcuts; safety is the top priority! In the upcoming bull market, I will guide everyone to aim for opportunities in the counterfeit market that can lead to wealth, with an expected space of over ten times being no problem. Like and comment, and I'll help you layout the entire bull market!

#钱包安全 May I ask if no one is playing on this platform, is it reliable or not?

A terrifying night in the cryptocurrency market! The crash swept through, and 290,000 investors lost all their money.

The cryptocurrency market suddenly exploded early this morning, scaring those of us in the cryptocurrency circle so much that we couldn't sleep well all night. The crash was so fierce that the prices of many major currencies fell so badly. Ethereum fell directly below $2,500, and Bitcoin also suffered, sliding all the way below $92,000.

Today, the cryptocurrency market was really crying. Bitcoin fell by more than 4%, and Ethereum was even more exaggerated, falling by more than 11%. There were also SOL, XRP, and Dogecoin, which couldn't hold up, falling by 16%, 11%, and more than 13% respectively.

This crash really hurt a lot of people. I heard that more than 290,000 investors were liquidated, and the total loss was $855 million.

This crash was not without reason. On the evening of February 21, there was a big news that the Bybit trading platform was hacked. Hackers stole $1.5 billion worth of tokens, a terrifying amount.

In the early hours of this morning, the price of the currency began to fall. Everyone was eager to sell in order to reduce their losses, but the more they sold, the more it fell. It was really a rainy night. On February 24, bad news came from South Dakota, USA, saying that a bill that might allow the state government to invest in Bitcoin was shelved. This bill would have allowed Bitcoin to be legally invested in the state, but now that it has been done, everyone has lost confidence in the future, and the price of the currency has fallen again.

In the cryptocurrency circle, there are risks and opportunities, but this plunge really sounded a wake-up call for us. Be careful when investing, look at the market situation more, and don't rush in. In this market, getting rich overnight and going bankrupt overnight are really just a little bit apart.

#钱包安全 On February 23, 2025, the crypto financial card king Infini encountered a big problem!
It seems that their platform has been hacked, resulting in 49.5 million US dollars disappearing from the $ETH account.
A security company called CertiK revealed that this money transfer was very strange, and it was later discovered that the money had been converted by hackers into 17,700 Ethereum coins, and then taken to a new address.
Infini's co-founder, Christine, who is usually active on social media, immediately came forward to make a statement. She said that this time it was not because the private key was stolen, but because during the internal transition, someone made a mistake. She also emphasized that the engineer who made the mistake had been found and controlled, and the company had also reported the incident to the police. Christine even guaranteed that Infini would provide full compensation to the affected users, wanting to keep everyone calm and not panic.
In addition, the leader of the blockchain security industry, Yu Xian, also said that they were monitoring the situation, stating that the hacker's skills were quite good. There are also reports from other parties that the hackers may have used a privacy mixing service called Tornado Cash to create chaos, making it seem like the issue was caused by poor management of private keys. Infini also admitted that this was an oversight by their own engineers.
