Odaily News, SlowMist Security Team disclosed that the cross-chain bridge project Allbridge suffered an attack on August 19, 2026, with losses of approximately $190,000. Notably, this attack was not executed instantaneously—the attacker began laying the groundwork nearly a month in advance, bypassing the verification mechanism through forged cross-chain messages.

According to SlowMist's analysis, on July 26, the attacker directly called Circle's MessageTransmitterV2.sendMessage function on the Polygon chain, constructing a cross-chain message disguised as CCTP-style, claiming a transfer of 1 million USDC, despite no actual USDC burn operation occurring. Subsequently, Circle generated a valid attestation for this complete message following standard procedures.

Approximately 24 days later, on August 19, the attacker waited for the Base Router to receive a genuine CCTP deposit, bringing its balance to approximately 191,000 USDC, then launched the attack just 6 seconds later. Using the previously forged message and attestation, the attacker called Allbridge's receiveCctpMessage function. Due to the project's lack of critical validation, the system mistook the fraudulent cross-chain message for a genuine deposit and recorded a 1 million USDC credit.

Subsequently, the attacker borrowed approximately 809,000 USDC temporarily via an Aave flash loan to match the Router's balance with the forged amount, then utilized the internal credit record to call the transfer function, ultimately moving out approximately 999,000 USDC (after deducting a 0.1% fee). After repaying the flash loan and fees, the attacker netted approximately $189,800 in profit. The root cause of this vulnerability lies in Allbridge's failure to verify the identity of the cross-chain message sender and receiver, as well as its failure to confirm whether USDC was genuinely minted or whether the balance actually increased—instead directly trusting the amount and message hash data constructed by the attacker.

SlowMist emphasized that on-chain message verification does not equate to actual asset arrival. Cross-chain protocols must not only verify message authenticity but also ensure the message source is trustworthy, confirm the receiver is Circle's official TokenMessengerV2, and only record assets after confirming actual minting and balance changes. This incident once again highlights the security risks in cross-chain bridges' message verification and asset settlement processes.

Odaily News: CZ stated on the X platform that the second-largest anonymous donor to Giggle was his previous "public address," thanking all those who contributed.

CZ previously stated that the BNB in the "public address" and the "Binance People" tokens purchased with BNB would be donated to Giggle Academy. He will then stop using this address, turning it into a burn address to avoid the community over-interpreting operations on the public address.

Odaily News: South Korean financial regulators plan to strengthen oversight of structured products such as ELS starting next month, requiring brokerages to issue warnings to investors when products approach the Knock-in trigger line for principal loss, and to reassess product design and sales when market conditions change and risks rise significantly.

It is understood that the South Korean stock market has recently experienced significant volatility, but retail investors' appetite for high-risk investments has not noticeably cooled. After regulatory tightening on single-stock leveraged ETFs, some investment has shifted toward equity-linked securities (ELS) offering high "coupon" yields. Data released by the Korea Financial Investment Association shows that ELS sales in South Korea reached 3.5 trillion KRW in July, hitting a new high since April 2023 and marking the strongest performance in over three years. ELS products based on Samsung Electronics and SK Hynix stocks have become the main growth driver.

Analysts believe that behind investors' pursuit of high yields lies optimism about the AI chip cycle and the future performance of semiconductor leaders. Although Samsung Electronics and SK Hynix stock prices have rebounded recently, they remain more than 22% below the historical highs set in June. Some investors believe that growth in HBM (High Bandwidth Memory) demand and the two companies' expanded shareholder return programs are expected to reduce the risk of further declines. (Bloomberg)

Odaily News: Metaverse gaming platform The Sandbox has confirmed a vulnerability in its cross-chain bridge, allowing attackers to mint unbacked SAND on Base and BNB Smart Chain. Blockchain security firm PeckShield detected on August 21 that two addresses had collectively minted approximately 14.9 billion SAND. The Sandbox subsequently shut down bridging functionality on both networks.

The Sandbox stated that the affected assets are bridged assets on Base and BNB Smart Chain, while SAND on Ethereum and Polygon, user wallet assets, and the Ethereum-locked assets backing the token remain unaffected. The proportion of genuinely collateralized assets involved in this incident is less than 0.01% of the total SAND supply.

The Sandbox is developing a compensation plan for affected liquidity providers and advises users not to trade SAND on Base or BNB Smart Chain until bridging is restored. Coinbase plans to delist 10 perpetual futures contracts, including SAND, on August 26, with open positions to be automatically settled at that time. (Bitcoin.com News)

Odaily News - CryptoQuant analyst Darkfost stated on the X platform that the altcoin market has recently shown clear signs of recovery, with market structure undergoing changes, and "Altseason" may have entered its early stages. Data shows that from August 19 to 22, the total market cap of altcoins increased by approximately $215 billion, surging over 24% in just 3 days, pushing the total altcoin market cap back above $1 trillion.

Darkfost pointed out that mid- and small-cap altcoins have performed the strongest in this rally. Due to their lower circulating market caps, these assets are more sensitive to capital inflows, while also carrying higher two-way volatility risks.

Data from the Binance platform further reinforces the signals of an altcoin market recovery. Since last November, approximately 80% to 85% of altcoins have remained below the 200-day moving average (200-DMA), but currently 56% of Binance-listed altcoins have climbed back above this key technical indicator, suggesting the market may be entering a new cyclical phase.

Darkfost believes this trend reversal is linked to a series of positive cryptocurrency signals recently released by Trump. On August 19, Trump stated that the U.S. would "massively purchase Bitcoin" and urged Congress to push through the CLARITY Act, while claiming his administration had ended previous unfriendly policies toward the crypto industry. These remarks boosted market sentiment, and against a backdrop of low trading volume and reduced selling pressure, substantial capital began flowing into the altcoin market, driving gains across multiple sectors simultaneously.

Darkfost noted that from a historical perspective, the current broad-based altcoin rally is typically viewed as an important signal of the early stage of altseason. However, he also cautioned that the market has entered overbought territory in the short term, and investors should be wary of periodic pullbacks. If the overall upward momentum continues, new investment opportunities may still emerge down the road.

Odaily News: Robert Kiyosaki, author of "Rich Dad Poor Dad," posted on social platform X that the new round of quantitative easing (QE) policy in the United States could lead to a decline in the purchasing power of the US dollar and further push up inflation risks. After the US Treasury Department announced a new round of QE, the US dollar index (DXY) may weaken, which means inflation pressure will rise, and those holding cash dollar savings could become the biggest losers. He warned investors not to rely on depreciating fiat currencies but instead focus on assets that can appreciate over time.

Robert Kiyosaki stated that financially literate investors tend to allocate assets such as gold, silver, Bitcoin, and certain real estate, while investors who lack financial education and hold "fake assets" for the long term may face a decline in their wealth. He once again emphasized the importance of financial education, citing his "Rich Dad" perspective: "The biggest cost is not the time and money spent on financial education, but the money that could have been earned but was missed."

Analysis suggests that Robert Kiyosaki has long been bullish on inflation-resistant assets such as Bitcoin and gold, and has repeatedly criticized the US dollar credit system. However, his views on QE and dollar policy are personal market judgments, and the actual monetary policy path still depends on US economic data and Federal Reserve decisions.

Odaily News, according to a research report by CITIC Securities, the recent correction in tech stocks cannot be simply attributed to high long-term U.S. Treasury yields. Behind the correction lies the issue of forward pricing for AI-related stocks, with three key narrative variables:

1) Whether the pace and scope of commercialization can keep up with market expectations;

2) Whether computing power advantages translate into market share and pricing power advantages;

3) Whether the current gap in computing power will significantly widen the long-term gap in AI models.

The current consensus concern is the pace and scope of commercialization, while the biggest potential variable is whether "distillation prevention" will re-widen the model gap in the future. As for macro factors, the impact of the U.S. Treasury's announcement to buy back long-term bonds is very limited. However, in the short term, both a weaker U.S. dollar and weaker rate hike expectations are conducive to the convergence of the global market's K-shaped divergence. Nevertheless, the factors driving the sustained rise in long-term U.S. interest rates have not fundamentally changed, and persistent disruptions may continue to emerge in the coming period. Under the influence of these external disturbances, the capital structure of the A-share market in the short term determines that the complexity of market gaming is still increasing. During such a volatile market phase, one should manage psychological expectations and avoid excessive grand narratives.
