Как хакеры вернули 43.6 BTC спустя 11 лет

История со счастливым финалом: европеец Майкл восстановил доступ к кошельку с 43,6 BTC, который считал потерянным с 2013 года.

Майкл сгенерировал сложный пароль через менеджер RoboForm

Ради безопасности он сохранил его в отдельном контейнере TrueCrypt, но файл со временем повредился

Доступ был заблокирован

В 2022 году Майкл нанял известного «белого» хакера Джо Гранда

Тот вместе с напарником провел обратный инжиниринг версии RoboForm 2013 года и обнаружил критический баг: Генератор случайных чисел RoboForm был дефектным

Создаваемые пароли жестко привязывались к дате и времени на ПК

Зная время создания, пароль становился предсказуемым.

Хакеры узнали дату перевода биткоинов и начали перебирать временные метки

В итоге они нашли верный пароль, созданный 15 мая 2013 года

Хакеры забрали долю, когда BTC стоил $38 000

Майкл зафиксировал часть прибыли по $62 000

Сейчас у него осталось 30 BTC (~$3 млн)

А вот англичанину Джеймсу Хауэллсу повезло меньше: он до сих пор ищет на свалке выброшенный жесткий диск с 7500 $BTC

If you're still trusting AI security tools blindly, stop now.

Crypto traders already deal with rugs, phishing links, fake airdrops, and wallet drainers. The scary part is that when things break, the “smartest” models may not even be allowed to help you understand the attack.

The latest twist: Hugging Face reportedly needed AI to analyze an attack, but top U.S. models refused because their safety filters couldn’t tell the difference between an attacker and a defender. That sounds responsible on one side, but in a live incident, hesitation can be expensive.

The other side is obvious: open-source AI can be risky if bad actors use it. But my take is that security teams need tools that can operate in the gray zone, especially as AI and crypto keep merging through sectors like $TAO , $FET , and $RNDR. If the “safe” models freeze during real attacks, defenders lose time while attackers keep moving.

Would you rather have stricter AI safety filters, or more open models that can actually help during cyber incidents?

🚨 اختراق جديد بقيمة 24 مليون دولار! ماذا يحدث في سوق الكريبتو؟ 🚨

$ETH $ARB

في حادثة أمنية جديدة، تعرض بروتوكول AFX Trade (المبني على شبكة Arbitrum) لاختراق ضخم أدى لسرقة أكثر من 24.15 مليون دولار من عملة USDC!

📌 أبرز التفاصيل:
• الهكر لم يضيع الوقت، وقام فوراً بتحويل الأموال المنسحبة لشراء 12,467 عملة ETH!
• التأكيد الرسمي: شبكة Arbitrum وجسرها الرئيسي سليمين 100%، والخلل كان في الجسر الخاص ببروتوكول AFX فقط.

💡 درس مهم لكل متداول:
التداول على منصات اللامركزية (DeFi) يحتاج حرص شديد، لا تضع كل رأس مالك في عقود ذكية واحدة مهماً كانت الميزات!

$BTC can look “calm” at $66,000 while the real risk is already scanning your wallet faster than any human can.

Traders get chopped up in markets like this because cautious sentiment feels safe, then one sudden exploit, AI-driven phishing wave, or liquidation cascade flips the mood. Fear & Greed near 33 says people are already nervous, and nervous markets punish sloppy entries.

The scary part is that the next “attacker” may not be a person manually hunting mistakes. It could be AI code scraping leaked seed phrases, generating fake support messages, cloning project sites, or timing scam links around volatile $BTC moves when everyone is distracted.

For $ETH and $SOL users, the lesson is simple: price risk is only one layer. Wallet hygiene, approvals, fake airdrops, and rushed trades matter just as much when sentiment is fragile. A quiet chart does not mean a quiet threat environment.

🚨 Robinhood CEO’s X Account Reportedly Hacked

According to Onchain Lens, the X account of Robinhood CEO Vlad Tenev has been compromised.

⚠️ Avoid clicking suspicious links
⚠️ Do not interact with token contracts
⚠️ Wait for confirmation from official Robinhood channels

The report concerns Tenev’s social media account and does not by itself indicate that Robinhood’s platform or customer funds were affected.

The user wants a safety awareness post about phishing attacks in crypto, written as a Binance Square content creator. Requirements:
- No markdown (so plain text, no formatting like ** or # unless it's the final hashtag line)
- 150-200 words
- Warning-style tone: serious but not panic-inducing
- 3 clear actionable steps
- End with: "Share this with someone new to crypto — it could save them!"
- Final line: #CryptoCommunity #Web3Gaming #CryptoSecurity #StaySafe (note: they wrote with spaces after #, but likely they want them as hashtags separated by spaces)

We must output ONLY the final post text, no extra commentary.

We need to count words roughly 150-200. Let's aim for ~170 words.

Write in plain text, no markdown. Use warning-style tone. Provide 3 steps, maybe numbered or bullet but no markdown bullet? Could use "1." "2." "3.".

End with the exact phrase: "Share this with someone new to crypto — it could save them!" then newline then the hashtags line.

Make sure no extra spaces or lines? Probably fine.

"Phishing remains the top threat for crypto users. Attackers mimic exchanges, wallets, and support channels to steal private keys and seed phrases. Stay alert and follow these three steps to protect your assets.

1. Verify every link before clicking. Hover over URLs to confirm the exact domain — official sites use binance.com, not binance-support.com or similar variations. Bookmark trusted pages and never enter credentials on a page you reached through email, DM, or social media.

2. Enable two‑factor authentication on every account and use a hardware authenticator app, not SMS. Store your recovery codes offline. If a service asks for your 2

🛡️ Two-Factor Authentication for Wallets: An Extra Layer of Account Security
On July 23, 2026, securing your crypto accounts requires more than just a strong password. Two-factor authentication adds a second verification step — typically a time-based code from an authenticator app or a hardware security key.
While 2FA protects against password theft, it does not secure on-chain assets controlled by private keys. It primarily guards exchange accounts and wallet application logins against unauthorized access.
For maximum security, combine 2FA with a hardware wallet, use authenticator apps rather than SMS-based codes, and never store backup codes digitally.

📌 Key Takeaway:
Two-factor authentication adds a critical second layer of security for exchange and wallet accounts, protecting against password-based attacks.

🛡️ Private Keys and Seed Phrases: Security 101 for Crypto Users
On July 23, 2026, with billions flowing through crypto every day, understanding private keys is the most important security lesson. A private key is a cryptographic secret that proves ownership of blockchain assets — whoever holds the key controls the funds.
Seed phrases (also called recovery phrases) are human-readable representations of your private key, typically 12 or 24 words. Losing your seed phrase means losing access forever — there is no password reset, no customer support recovery.
Never share your private key or seed phrase with anyone. Legitimate services will never ask for them. Write them down on paper and store them in a secure offline location.

📌 Key Takeaway:
Your private key is the ultimate control over your crypto assets — losing it means permanent loss, and sharing it means giving away ownership.

📚 Trading Tip of the Day — Hot Wallet vs. Cold Wallet

$BTC


After today's news about $35.55M in hacks, this is a good time to cover the basics of keeping your crypto secure.

🔍 What is a hot wallet?

A wallet connected to the internet (exchange accounts, mobile apps, browser extensions). Convenient for active trading, but constantly exposed to online threats — hacking, phishing, exchange breaches.

🔍 What is a cold wallet?

A wallet that stores your private keys completely offline (hardware wallets like Ledger/Trezor, or even paper wallets). Nearly immune to remote hacking since there's no internet connection to exploit.

📊 The trade-off:

Hot wallets = convenient, faster access, but higher risk
Cold wallets = safer for long-term storage, but slower/less convenient for active trading

🔑 A common approach many traders use:

Keep only what you need for active trading on an exchange (hot wallet), and move larger, long-term holdings to a cold wallet. This way, even if an exchange gets hacked, your main holdings stay protected.

❌ Common mistake beginners make:

Keeping 100% of their holdings on an exchange indefinitely, treating it like a bank account. Exchanges can be hacked, frozen, or face technical issues — "not your keys, not your coins" is a common phrase in crypto for a reason.

📌 Golden rule: For any amount you're not actively trading, moving it to a cold wallet significantly reduces your exposure to exchange-level hacks like the ones we saw today.

📰 Security News Take — July 23, 2026

$BTC


Three separate crypto hacks hit today, totaling $35.55M in combined losses: AFX Trade lost $24.15M, VerusCoin's Ethereum bridge was breached for $7.55M, and B² Network reported a $3.86M incident.

🤔 Why this matters beyond the headlines:

Bridge protocols and smaller exchanges remain the most consistently exploited targets in crypto — this isn't a one-off, it's a recurring pattern. Cross-chain bridges in particular have been a favorite attack vector for years because they often involve complex code connecting multiple blockchains, creating more potential vulnerabilities.

📊 The bigger picture:

Despite headline-grabbing hack totals, they're a small fraction of the ~$2.3 trillion total crypto market cap. That said, for anyone directly affected (users of these specific platforms), the losses are real and often unrecoverable.

🔑 What this means for you as a trader/holder:

This is a good reminder that platform choice matters. Established, well-audited exchanges and DeFi protocols with a track record generally carry lower (though never zero) security risk than newer or smaller ones.

📌 My take: Security incidents like today's are a recurring cost of this industry's rapid growth, especially for less battle-tested projects. Doesn't mean avoid crypto entirely — it means being deliberate about where you hold funds and how much you keep on any single platform.

Crypto hacks: security still a major concern. Two crypto bridge attacks this week saw $31.6M stolen within hours. AFX, a decentralized exchange on Arbitrum, lost over $24M, and then the Verus Ethereum bridge was hit. Crypto bridges are crucial for moving assets between different blockchains, allowing them to interoperate. Think of them as digital tunnels connecting separate cities. These attacks highlight a critical vulnerability in the crypto ecosystem. When a bridge is exploited, it creates a weak point where malicious actors can siphon off significant funds. This isn’t just about the projects themselves; it shakes user confidence in the security of cross-chain transactions overall. This news reminds us that while innovation in crypto is rapid, security needs to keep pace. Consistent audits and robust infrastructure are non-negotiable for a healthy ecosystem. We're seeing projects like $BANK gain over 76% today, showing immense growth potential, but security remains the bedrock.

今天最魔幻的不是价格，而是资金还在装睡，黑客已经先开工了……

Binance 现货这边，$BTC 24小时在 65,448 USDT 附近，跌幅约 -0.72%；$ETH 更像原地磨人，约 1,916.92 USDT，24小时 -0.03%。看起来不刺激，但新闻面一点都不安静：CoinDesk 刚报，和 Bitcoin、Ethereum 相关的多个协议在数小时内遭遇攻击，合计损失约 3500 万美元，其中 Arbitrum 生态 AFX Trade 因桥密钥问题被抽走约 2400 万美元。

说人话：盘面没给方向，风险却在提醒大家别只盯K线。

我更关心两条线：第一，$BTC 如果继续贴着日内低位磨，市场情绪可能会从“等突破”变成“先降仓位”；第二，$ETH 相关生态安全事件如果继续发酵，DeFi/L2 资金会不会短线更谨慎。

这位置别上头。价格没大跌，不代表风险没变；坏消息没砸盘，也不代表已经消化。接下来我会看 BTC 能不能重新站回日内均价区，以及 ETH 生态相关项目有没有进一步披露。

everyone thinks the easiest chain to use is automatically the best chain to trade on, but actually that’s where a lot of people get clipped.

ngl, cheap fees and smooth txs can make you ape faster than you think. the pain starts when “accessible” turns into crowded memecoin casinos, weak contracts, bad opsec, or bridges you never really understood.

real case study: every blockchain is fighting the same 2-sided war, accessibility vs security. $SOL made onboarding feel fast and cheap, $BNB made trading feel simple for retail, and $ETH stayed more conservative but often priced smaller users out during peak demand.

the common mistake is picking a chain only because it feels easy. ser, easy is good, but if you ignore security assumptions, validator setup, contract risk, bridge exposure, and wallet hygiene, that “cheap entry” can become the most expensive trade you take.

where do you think the best balance is right now: $ETH , $SOL , or $BNB ? #CryptoSecurity #Blockchain #Binance

If you’re still choosing chains only because they’re cheap and easy to use, stop now.

That mistake has cost traders real money when convenience turns into weak assumptions. Low fees and smooth onboarding feel great until a security trade-off shows up after you’ve already bought the top or bridged funds in.

The breaking reminder here is simple: every blockchain has to balance accessibility with security. Push too hard toward accessibility and you get faster adoption, easier wallets, lower friction, and more users flowing into ecosystems like $SOL , $BNB , and $ETH L2s.

But the other side matters more, in my view. If security is treated like a feature instead of the foundation, the whole value proposition gets shaky. Traders don’t just need speed. They need confidence that the chain, bridge, app, and assets won’t become the next painful lesson.

So where should crypto draw the line: should blockchains prioritize mass adoption first, or security at all costs?
