Resumo

Un incident majeur de sécurité a touché le réseau Harmony, une blockchain de première couche lancée en 2019. Une vulnérabilité présumée dans son protocole a permis l'émission non autorisée d'environ 4 milliards de jetons ONE, représentant près de 26% de l'offre totale. À la suite de l'attaque, Harmony a identifié ces jetons illégitimes répartis sur 409 portefeuilles et plus de 10 000 transactions anormales. L'équipe du projet a contacté des plateformes d'échange centralisées pour bloquer les mouvements de fonds suspects et a ciblé quatre groupes d'adresses à geler. Environ 53% des validateurs du réseau ont déployé une mise à jour pour prévenir de nouvelles émissions frauduleuses. Cette exploitation a provoqué un effondrement brutal de la valeur du jeton ONE, qui a chuté d'environ 40% pour atteindre près de 0,000747 dollar selon CoinMarketCap.

L'un des incidents de sécurité les plus marquants sur le marché des cryptomonnaies s'est produit aujourd'hui sur le réseau Harmony. Harmony, une blockchain de première couche lancée en 2019, a subi une nouvelle attaque majeure après plusieurs années.

À ce stade, une vulnérabilité présumée dans le système de sécurité du protocole Harmony a été découverte, ayant conduit à l'émission non autorisée d'environ 4 milliards de jetons ONE.

La société Harmony a déclaré que ce montant représente approximativement 26% de l'offre totale de ONE gérée par l'entreprise.

Harmony a également annoncé que son enquête menée après l'attaque a révélé environ 4 milliards de jetons ONE non autorisés dans 409 portefeuilles différents et un total de 10 288 transactions anormales.

Les bourses mettent en garde contre des transactions suspectes !

Dans sa déclaration, l'équipe a également indiqué qu'après l'incident, elle avait contacté les bourses de cryptomonnaies centralisées pour commencer le travail de prévention des mouvements de fonds suspects. À ce moment-là, le projet a spécifié avoir identifié quatre groupes d'adresses de portefeuilles et a demandé aux bourses de bloquer les fonds envoyés vers ces adresses.

Selon la description du projet, environ 53% des validateurs du réseau ont installé une mise à jour logicielle empêchant l'émission non autorisée de jetons.

Le prix du ONE s'effondre !

Après la découverte de la faille de sécurité, le prix du ONE a chuté brutalement. Selon les données de CoinMarketCap, suite à cette nouvelle, le jeton ONE a perdu environ 40% de sa valeur, tombant autour de 0,000747 $.

Ireland plans industry standards for illicit crypto use

The Irish government has published its first comprehensive National Anti-Money Laundering, Countering Financing of Terrorism and Countering Proliferation Financing Strategy. It outlines new measures to regulate digital assets and crypto-asset service providers to prevent their use for illicit activities. Key proposals include introducing Anti-Money Laundering and Counter-Terrorist Financing obligations for crypto service providers, requiring enhanced checks on transfers to and from private crypto wallets, and stricter due diligence for dealings with overseas crypto firms. The strategy also plans to address industry standards concerning the acceptance of crypto-related funds for gambling. This follows a recent national risk assessment on crypto, with Ireland aiming to implement these industry standards by the second half of 2027. The legislation aligns with the EU's Markets in Crypto Assets (MiCA) regulatory framework.

Grayscale: "If the Proposals Are Adopted, the Prices of These Two Altcoins Could Rise"

Grayscale's Head of Research, Zach Pandl, stated that proposed changes to the tokenomics of Ethereum ($ETH) and Solana ($SOL) could significantly slow their supply growth rates, potentially boosting prices. The discussed code modifications aim to reduce the annual inflation of ETH and SOL tokens. Slower supply growth could decrease the number of new tokens entering the market, increasing scarcity. Grayscale estimates that if implemented, Ethereum's annual supply inflation could fall to about 0.4% by late 2031—close to Bitcoin's rate—while Solana's could drop to roughly 1.1%. For context, this compares to gold's ~1.8% annual supply growth and the US CPI inflation of ~3.3%. While the proposals are still under community discussion and not finalized, Pandl noted that Solana's changes appear to have broader support and a higher likelihood of adoption. However, lower token inflation might also reduce staking rewards, as a significant portion comes from new token issuance. Pandl concluded that the reduced supply could increase scarcity and upward price pressure, particularly benefiting investors holding non-staked tokens.

Experts Named Reasons for Bitcoin's Decline After US Inflation Drop

Despite favorable U.S. inflation data in July, Bitcoin failed to rally and instead declined. Analysts from CryptoQuant identify weak spot market demand as the primary cause. After the data release, Bitcoin briefly dropped from around $64,500 to $63,000. While the Producer Price Index (PPI) was better than expected, and U.S. stock indices rose, Bitcoin remained stuck in a range. Key indicators point to subdued demand: capital inflows into U.S. spot Bitcoin ETFs remain low, and the Coinbase Premium Index has been negative since May, indicating limited buying pressure from American investors. In contrast, positioning in the futures market remains relatively high, creating an imbalance of weak spot demand, low liquidity, and significant leveraged positions. Analysts warn that under these conditions, even positive macroeconomic news may not spur growth. If the price doesn't react to a favorable backdrop, traders might start closing margin longs, adding further downward pressure. A key resistance level is identified at $68,700, the approximate cost basis for short-term holders, which could trigger selling. For a sustained rally to resume, CryptoQuant states the market needs: renewed capital inflows into U.S. Bitcoin ETFs, the Coinbase Premium Index turning positive, an increase in spot trading volumes, and a decisive break above $68,700.

Bitcoin Price Drops to $62,470 as Sellers Retest $63,000 Support Level

Bitcoin's price fell below $63,000 for a second consecutive day on Friday, hitting an intraday low of $62,470. The cryptocurrency later recovered to trade just above $63,000, leaving it nearly flat for the past 24 hours and for August overall, with a weekly loss of 2.6%. The volatility triggered significant liquidations, with $26 million of leveraged long Bitcoin positions liquidated over 24 hours. Market sentiment was further dampened by data showing over $131 million in outflows from spot Bitcoin ETFs for a second straight day, signaling a potential pullback by institutional investors. Adding to the negative pressure, index provider MSCI has proposed new criteria for "non-operating companies" in its global indexes, which could lead to the exclusion of firms holding significant digital assets like Bitcoin on their balance sheets. Companies such as Strategy and Metaplanet could be affected, potentially forcing index-tracking funds to sell their shares. Strategy publicly criticized the proposal, arguing digital assets are legitimate assets and index providers should not dictate what companies can own. Public consultations on MSCI's proposal end September 30, with a final decision expected by October 16. If approved, exclusions could begin in November, potentially triggering sustained institutional selling and damaging a key bridge for Bitcoin adoption in the corporate sector.

Secretly Mined 1 BTC on Work Computers: Crypto Firm Employee Faces Prison

Christopher Rankin, a 40-year-old from Washington state, pleaded guilty to unauthorized access to computers at a bitcoin mining company and theft of cryptocurrency. While employed at the New York-based company starting in July 2021, Rankin gained unauthorized access to approximately 100 company computers. He manually rebooted them and redirected their mining power to a fraudulent mining pool he controlled, causing the mined bitcoin (1.0668 BTC, worth approximately $53,315 at the time) to be sent to wallets under his control. Additionally, he set the computers to a high-performance mode, which prosecutors stated caused physical damage, significantly reducing their lifespan, and compromised the integrity and availability of data stored on them. Rankin was found guilty of transmitting a program, information, code, or command to a protected computer, causing damage. The maximum penalty for this offense is up to one year in prison and a fine of up to $100,000. His sentencing is scheduled for November 17, 2026, before U.S. Magistrate Judge Michael J. Roemer.
