A family in the northern French town of Vendin-le-Vieil was invaded and taken hostage by four masked men early Sunday morning. According to BFMTV, the suspects entered the house around 4 AM, binding the couple and their two children with tape, and held them for over three hours. The 40-year-old father, an IT expert in the local cryptocurrency industry, was taken to another room, beaten, and forced to give up access codes, resulting in approximately 40,000 euros (about 46,000 dollars) worth of cryptocurrency being transferred away.According to the Béthune prosecutor's office, the four suspects fled the scene by car and are still at large. The 12-year-old daughter was struck in the face with a car key during the incident, and the victims are in a state of shock; they have been sent for forensic examination and are receiving support from the victims' assistance association. The case has been filed under organized gang kidnapping and extortion and is being jointly investigated by the regional judicial police and the French Cybercrime Office.France is the country most severely affected by such "ransom attacks" globally. Records from the national prosecutor's office for organized crime show that over 70 kidnapping and illegal detention incidents related to cryptocurrency have occurred in the first eight months of 2026, with 88 people already prosecuted in earlier crackdowns this year. Previous similar cases often targeted wealthy individuals, including the father of a cryptocurrency millionaire, the wife of a co-founder of The Sandbox, and the CEO of Binance France, while the victim in this case is merely an ordinary IT professional. Chainalysis reported that global ransom attacks in 2026 resulted in approximately 30 million dollars in losses, while CertiK stated that losses over six months reached 124 million dollars, a 12-fold increase.

According to Fortune, Robinhood has recently tokenized stocks like AMC, which has led to public criticism from AMC's CEO. However, this model can reduce the cost and threshold for global investors to trade U.S. stocks. Blockchain-driven stock tokenization is reshaping the U.S. brokerage industry, and its impact may be similar to that of Napster on the music industry 25 years ago.Analysis points out that tokenized stocks still face issues such as voting rights, underlying stock custody, and whether token assets are fully backed. However, regulators have begun to promote the construction of relevant frameworks. Recently, Nasdaq also invested $100 million in blockchain financial company Payward, and the trend of stock on-chain is accelerating, making it difficult for threats or lawsuits to long-term hinder the development of this technology.

The Sandbox released an update on the security vulnerability attack incident involving the SAND cross-chain bridge, stating that the attacker modified the verification mechanism to forge cross-chain deposit messages and mint unbacked SAND. This incident resulted in approximately 14.7423 million SAND being withdrawn, valued at about $697,000. Additionally, some uncollateralized SAND was profited through market trading, leading to an overall economic impact of approximately $1.497 million, of which the attacker actually obtained about $987,000.The Sandbox stated that the attack did not affect the supply of SAND on Ethereum and Polygon, with the total amount of SAND on Ethereum remaining unchanged at 3 billion. There were also no super administrator privileges stolen, and the attack stemmed from a vulnerability caused by the combination of the general call function in the token contract and the design of bridge permissions. Currently, the related addresses have been marked, and collaboration has begun with exchanges, security agencies, and the LayerZero team.For affected users, The Sandbox promises to compensate wallets holding legitimate bridged SAND with a 1:1 ratio of SAND on the Ethereum chain based on an on-chain snapshot taken before the attack.

According to official news, the prediction market Polymarket announced a significant adjustment to its settlement mechanism for cryptocurrency price fluctuation markets starting from August 7, to protect market integrity. From midnight UTC on that day, the affected markets will no longer settle based on a single price snapshot at a specific time but will instead use a time-weighted average price.Markets of different durations correspond to different TWAP windows: all cryptocurrency 5-minute markets will use a 30-second TWAP, 15-minute markets will use a 60-second TWAP, and 4-hour markets will also use a 60-second TWAP. The previous single snapshot settlement method was prone to price manipulation during periods of low liquidity, and this change is a proactive reinforcement of the market integrity system by Polymarket after facing regulatory scrutiny.To support this transition, Polymarket will inject $1 million in liquidity rewards into all affected markets throughout August. On the technical side, Chainlink TWAP testnet data streams are now available, and mainnet data streams along with Polymarket real-time data stream services will go live on August 4, at which point developers can access TWAP prices directly through Chainlink Data Streams or Polymarket's public WebSocket.
