To defend against these threats, researchers and industry leaders are working on post-quantum cryptography (PQC). These are algorithms designed to withstand attacks from quantum computers while remaining secure and efficient for classical computers.

Some of the most promising post-quantum algorithms include:
CRYSTALS-Dilithium – a lattice-based digital signature algorithm.XMSS – a hash-based signature scheme.Lattice-based cryptography in general, which relies on mathematical structures believed to be resistant to quantum attacks.

Implementing these quantum-resistant algorithms will likely require hard forks in blockchain networks, as well as consensus within the crypto community to ensure seamless transitions.

What can crypto asset holders do today?
Stay informed about quantum computing developments.Look for projects that are actively researching or adopting PQC solutions.Diversify your assets and consider using multi-signature or hardware wallets.Support community efforts to test and integrate PQC into existing blockchains.

A particularly fascinating scenario is the future of Satoshi’s wallet and early Bitcoin addresses, which rely on older cryptographic schemes that would be among the first to be cracked if a powerful enough quantum computer becomes available.

Looking Ahead
While quantum computing is not an immediate threat, its rapid progress means that proactive measures are crucial to safeguard the crypto ecosystem. Collaboration between researchers, blockchain developers, and asset holders will be essential to ensure a smooth transition to a quantum-secure future.
Whether Q Day is five, ten, or twenty years away, the time to prepare is now.

A recent update in one of the leading altcoins — specifically Ethereum — has introduced an advanced yet potentially dangerous feature that has quickly become a tool for exploitation. Crypto trading firm Wintermute has issued a serious security alert regarding the misuse of EIP-7702, a new feature launched as part of the Pectra hard fork.

🔹 EIP-7702: Innovation or Exploitation Risk?

The feature EIP-7702 introduces a concept called account abstraction, which allows regular wallets to temporarily function as smart contracts. Promoted by Ethereum co-founder Vitalik Buterin, the function is designed to enable users to:

🔹 batch multiple transactions,

🔹 let someone else pay for gas fees,

🔹 and use social authentication within a single transaction.
However, this innovation has quickly turned into a security threat in the wrong hands.

Wintermute: Over 80% of EIP-7702 Usage Is Malicious
According to data analyzed via Dune Analytics, Wintermute revealed a troubling trend:
More than 80% of EIP-7702 delegations are being exploited in “CrimeEnjoyor” attacks.
The method is simple — a short, copy-pasted smart contract code is repeatedly deployed across different addresses. The contract automatically transfers assets from wallets (whose private keys have been leaked) to addresses controlled by the attacker.
“The CrimeEnjoyor contract is short, simple, and widely used,” Wintermute reported. “This replicated bytecode now dominates EIP-7702 delegations. It’s darkly ironic.”

Scam Sniffer and SlowMist Also Issue Warnings
Other security firms have echoed Wintermute's concerns:
🔹 Scam Sniffer reported a malicious transaction linked to the notorious Inferno Drainer scam network, which led to losses of approximately $150,000.

🔹 SlowMist emphasized that wallet providers must support clear identification of destination addresses in smart contracts that users are prompted to sign.
Experts are urging increased transparency and user education to prevent unsuspecting users from authorizing harmful transactions.

❗ Recommendations for Users
🔹 Carefully review smart contract content before signing

🔹 Avoid unverified or suspicious apps utilizing EIP-7702

🔹 Use wallets with enhanced security features and alerts

🔹 Follow tools like Scam Sniffer to detect threats early

💬 Question for readers: Do you believe features like EIP-7702 are the future of crypto wallets—or too risky for widespread adoption?

Quantum computers pose a significant challenge to the security of cryptocurrencies and blockchain-based assets. Current cryptographic systems rely on mathematical problems that are extremely hard for classical computers to solve, like factoring large prime numbers. However, quantum algorithms such as Shor’s algorithm can solve these problems exponentially faster.

Here are the four main risks posed by quantum computing to crypto assets:
Breaking Private Keys

Quantum computers can break the cryptographic schemes protecting private keys, making it possible to steal funds from wallets. It’s estimated that around 4,000 logical qubits would be needed to break widely used public-key cryptography, such as RSA and ECC (Elliptic Curve Cryptography).
Dominating Mining

Quantum computers could outperform classical miners, monopolizing block creation and disrupting the network’s fair distribution of rewards.Smart Contract Vulnerabilities

Quantum attacks can target smart contracts and decentralized applications, potentially changing their behavior or bypassing security measures.
Loss of Trust

If quantum attacks become feasible, trust in blockchain networks could erode, leading to a collapse in confidence and the value of digital assets.

Currently, the IBM Condor chip – with 1,121 qubits – represents a major milestone. Google’s research suggests that millions of physical qubits would be needed for large-scale quantum error correction, so we’re not yet at the point of quantum supremacy in breaking crypto, but progress is accelerating.

By Binance Editorial Team | Crypto Flashback | August 15, 2010 – The Forgotten Fork That Saved It All

Before #Bitcoin2025 $BTC
Bitcoin ($BTC ) reached $70,000…

Before institutions called it an asset class…

Before the world hailed it as digital gold — it almost vanished.
On August 15, 2010, Bitcoin came seconds from self-destruction. One transaction, one bug, and one obscure line of code brought the entire Bitcoin network to its knees. It's a story rarely told — but it’s one every crypto investor should know.
💥 The Transaction That Broke the Rules
In 2010, Bitcoin was in its infancy. One BTC traded for just 7 cents. Mining was done on laptops. The whitepaper was still fresh.
Then, out of nowhere, a transaction appeared on the blockchain that sent 184,467,440,737 BTC to a single wallet.
Yes — that’s over 184 billion BTC.

More than 8,800 times Bitcoin’s hard-coded supply cap of 21 million.

It shouldn’t have been possible. But it happened.

🐛 The Bug in the Code

The culprit? A critical integer overflow bug in Bitcoin's codebase — a software flaw that caused the system to mishandle large numerical values. The attacker exploited it to create a near-infinite number of bitcoins from thin air.

For a few terrifying hours, the unthinkable became reality.

Bitcoin’s core principle — scarcity — was broken.

Had this continued unnoticed, Bitcoin could have collapsed entirely.

🧑‍💻 Satoshi Responds
Bitcoin’s anonymous creator, Satoshi Nakamoto, acted fast.

Detected the exploit within hoursPublished a patch in Bitcoin version 0.3.10Coordinated a hard fork to invalidate the exploitRewrote the blockchain to erase the fraudulent transactionIt marked the only time in Bitcoin’s history that a transaction was manually removed and the chain was rolled back.
The network split. Honest nodes rejected the corrupted chain. Consensus returned. Bitcoin survived.

🔁 The Fork That Changed Everything
This emergency fork — known to some as the day Bitcoin almost died — serves as a sobering reminder:

Bitcoin is software. And software can fail.

The 184 billion BTC bug shattered the illusion of invincibility. It exposed how dependent early Bitcoin was on a small group of developers — and just how fragile the system was before global adoption, hashpower, and decentralized infrastructure took root.

❓Could It Happen Again?

Today, Bitcoin has matured. It’s undergone audits, core rewrites, and network upgrades. The odds of such a catastrophic bug slipping through again are dramatically lower.

But no system is entirely immune. Bitcoin’s strength lies in its open-source nature, community vigilance, and the transparency of its code.

🧠 Lessons from the Brink
Bitcoin is resilient, not invulnerableTrust in the network is built — and can be brokenDecentralized communities must remain alertSo the next time someone says “Bitcoin can’t fail”, remember: it almost did.
And it’s only because of fast thinking, open collaboration, and a handful of anonymous heroes that we still have it today.

Quantum computing is a cutting-edge field that leverages the unique properties of quantum mechanics to perform computations far beyond the reach of classical computers.
At its core, quantum computing uses qubits (quantum bits) instead of traditional bits (0s and 1s). Qubits can exist in a state of superposition, meaning they can represent both 0 and 1 simultaneously. This allows quantum computers to process an enormous amount of information in parallel.
Another crucial phenomenon is entanglement. When qubits are entangled, the state of one qubit instantly affects the state of another, regardless of distance. This enables quantum computers to perform complex calculations with unprecedented speed and efficiency.
Classical computers process data sequentially, using binary logic. Quantum computers, in contrast, harness the probabilistic nature of quantum mechanics to explore multiple solutions at once, promising breakthroughs in fields like materials science, cryptography, and finance.
Currently, quantum technology is still in its early stages, with researchers working on stabilizing qubits and scaling up the number of usable qubits in quantum processors. Major players like IBM, Google, and Rigetti are pushing the boundaries of what’s possible.
A term that has gained traction in the quantum community is Q Day – the moment when quantum computers become powerful enough to break existing cryptographic systems. While we’re not there yet, it’s a looming event that drives much of the current research and preparation.

Saudações comudidade Glogal Cryptograma!
Percebemos que com a recente euforia e as altas do mercado cripto, um assunto crucial tem emergegido das sombras e exige nossa atenção: a segurança física de quem detém ativos digitais. Não é alarmismo, é preparo estratégico.
O artigo recente da Equipe de Segurança Física da Binance (que você pode conferir no blog da Binance) joga luz sobre uma tendência preocupante: embora ainda raros comparados a crimes comuns, os ataques físicos direcionados a investidores e profissionais de cripto estão aumentando, especialmente em períodos de alta do mercado.
Por Que Isso Importa AGORA?
Criminosos estão cada vez mais sofisticados. Se as defesas digitais se fortalecem, eles buscam o "elo mais fraco", que muitas vezes pode ser o próprio indivíduo no mundo físico. Casos de sequestro e coação para transferência de fundos, como o do cofundador da Ledger em janeiro de 2025, são um duro lembrete de que a segurança 360º é vital.
Onde Mora o Perigo?
Regiões em Foco: América do Norte, Europa Ocidental e Sudeste Asiático têm visto um número maior desses incidentes.
Quem é o Alvo? Indivíduos com exposição pública (influenciadores, empresários do setor, traders conhecidos) ou aqueles que se presume terem acesso direto a grandes volumes de criptoativos.

Blindando Sua Fortaleza Cripto (Além do Digital): 5 Pilares Essenciais
Discrição é Poder: Evite ostentar seus holdings ou ganhos em plataformas públicas. Sua "identidade cripto" online não precisa gritar riqueza. Menos holofotes, menos alvos.
Privacidade Digital Reforçada: Suas redes sociais podem ser um mapa para criminosos. Desative geotags, evite compartilhar planos de viagem em tempo real e configure suas contas para o modo privado.
Ofusque a Propriedade de Carteiras: Não vincule publicamente seu nome a endereços de carteiras. Explore ferramentas e carteiras que priorizem a privacidade em suas transações on-chain.
Consciência Situacional Aguçada: Sua rotina pode ser seu calcanhar de Aquiles. Varie trajetos, seja discreto em eventos cripto e, se necessário, considere auditorias de segurança para sua residência ou escritório.
Planos de Contingência Robustos: Tenha um plano de crise. Carteiras multi-assinatura (multisig) ou módulos de segurança de hardware (HSMs) podem impedir transferências forçadas. Em caso de ameaça, contate as autoridades IMEDIATAMENTE.
A Binance tem trabalhado ativamente com autoridades para combater esses crimes, mas a primeira linha de defesa é VOCÊ.
Para Reflexão, Cryptograma:
Você já parou para pensar na sua segurança física no contexto dos seus investimentos cripto? Quais medidas você já adota ou pretende adotar? Compartilhe suas estratégias e dúvidas nos comentários! Vamos fortalecer nossa comunidade com conhecimento e precaução.

A seemingly minor yet critical bug in the code of the decentralized protocol Cetus has cost users a staggering $223 million. A detailed analysis by the cybersecurity firm Dedaub revealed a serious flaw in the logic of Cetus' automated market maker (AMM), which hackers were able to exploit on a massive scale.

⚠️ Subtle Bug, Devastating Consequences
According to Dedaub, the main cause of the exploit was an "overflow" bug—a technical vulnerability that arises when a system fails to handle large numerical inputs correctly during mathematical operations.
Instead of rejecting these oversized values, the system improperly truncated them, which made the resulting output appear far smaller than it actually should have been. The attacker exploited this flaw by depositing only a single token, yet the protocol mistakenly credited them with a massive liquidity position. That position was then used to withdraw substantial real assets from liquidity pools.

💻 The Bug Survived Migration to Sui Network
Even after the Cetus codebase was migrated to the Sui blockchain, the critical vulnerability remained intact. Developers did attempt to implement security checks, but the overflow protection was flawed, allowing the same type of exploit to slip through unnoticed once again.
“This incident highlights why edge cases in DeFi cannot be overlooked,” Dedaub warned, emphasizing that the complex math behind decentralized finance systems requires rigorous manual auditing and extreme caution.

📉 Fallout: Token Crash and Market Panic
The Cetus exploit occurred in the early hours of May 22, marking one of the largest financial losses ever recorded within the Sui ecosystem. Initial reports pointed to a potential Oracle error, but deeper investigation revealed that the core issue was much more serious.
The exploit led to over $223 million in losses across various liquidity pools. The breach immediately triggered a massive token sell-off, with SUI and CETUS tokens plummeting over 40% in just a few hours. Smaller memecoins and low-cap tokens suffered even more dramatic drops—some losing more than 90% of their value.

🔒 Response: Freezing Funds and Bounty Offer
In a coordinated response, the Sui Foundation worked with validators in an attempt to freeze approximately $163 million of the stolen assets. Cetus also announced a $5 million bounty for information that could lead to identifying the attacker.

📌 Summary
🔹 A simple code bug caused one of the biggest DeFi thefts

🔹 The attacker exploited an overflow bug to gain a huge liquidity position

🔹 Token prices plunged as panic spread across the market

🔹 Efforts are underway to freeze stolen funds and track the perpetrator

What’s your take on this? Are DeFi protocols still too vulnerable to replace traditional financial systems?

U.S. cryptocurrency exchange Coinbase is under fire—this time in the form of a class action lawsuit. Investor Brady Nessler claims the company withheld crucial information about a serious data breach and failed to disclose regulatory issues in the UK, ultimately harming shareholders.
According to the lawsuit, Coinbase deliberately delayed disclosing a security incident that compromised customer data and failed to properly inform investors about a $4.5 million fine imposed by the UK’s Financial Conduct Authority (FCA). Both events allegedly had a negative impact on stock value and investor trust.

Data breach and extortion: details emerged too late
Coinbase reportedly fell victim to a sophisticated cyberattack during which hackers obtained sensitive client data, including names, addresses, and identification information. The attackers allegedly bribed foreign support staff to gain access.
More troubling, the lawsuit states Coinbase kept this incident hidden from the public. It wasn’t until May 15, 2025—months after the breach—that the company confirmed a $20 million extortion attempt. On that same day, Coinbase stock dropped sharply by 7.2%, closing at $244 per share.
“By keeping this hidden, investors lost millions. Coinbase breached its duty to inform shareholders and caused serious harm,” the lawsuit claims.

Second blow: fine from UK regulators
The lawsuit also references a July 2024 fine from the FCA, imposed on Coinbase’s British subsidiary, CB Payments Ltd. The regulator found that CBPL allowed access to over 13,000 high-risk users in violation of a 2020 agreement banning such onboarding.
As a result, nearly $226 million in crypto transactions were processed illegally. When this fine was announced, Coinbase’s stock fell 5.52% to $231.52 per share.

Lawsuit demands: compensation and a trial
Nessler is requesting class action status for the suit and is seeking financial compensation for all shareholders who purchased COIN stock between April 2021 and May 2025. He is also asking for legal fees to be covered and for the case to go to jury trial.
Coinbase has not yet issued a public response. Since the disclosure, COIN shares have partially recovered but still dropped 3.23% on May 23, closing at $263.10, according to Yahoo Finance.
