Odaily reports, citing official French data: between January 1 and mid-August 2026, France recorded a total of 90 crypto-related kidnapping, extortion, threat, and violent theft cases, with police carrying out 223 arrests; from January to July, 126 people were imprisoned. According to Chainalysis, as of mid-2026, France had 30 publicly recorded crypto-related violent attacks; Gart.io tracked 73 real-world attacks in France during the year, higher than 66 in the United States and 27 in the United Kingdom. Eric Jardine, head of research at Chainalysis, said the increase in attacks may be related to large-scale data leaks, and the leaked information may include the identities, addresses, and asset information of cryptocurrency holders.

Odaily News: An armed robbery occurred at a luxury residence near Pattaya, Thailand, where three armed individuals broke into a gated community and took control of a Chinese national holding Turkish citizenship, forcing him to open a safe and hand over cash and 3 luxury watches.The attackers also forced the victim at gunpoint to transfer $820,000 worth of cryptocurrency to one of their wallets, which was immediately sold afterward. After escaping, the victim reported the incident to the police, who have not yet confirmed the nationalities of the three suspects.Police Region 2 has launched an investigation and identified the getaway vehicle through surveillance footage; the vehicle was later abandoned in a remote area. Police are tracking the sold digital assets to identify the relevant accounts and recover the funds. Chainalysis estimates that over $30 million in cryptocurrency has been stolen in such violent robberies in the first half of 2026. (Bitcoin.com News)

Odaily News: A 2021 firmware vulnerability in the hardware wallet Coldcard resulted in insufficient randomness in some recovered seeds. Since July 30, attackers have transferred approximately 1,600 to 1,800 BTC from affected wallets, involving thousands of addresses, with an estimated value exceeding $100 million.Coldcard manufacturer Coinkite stated that it must be assumed that someone used AI to review its public firmware. The vulnerability has existed for about five years, and whether AI was involved in the related attacks has not yet been confirmed.Shielded Labs researcher Taylor Hornby used a Claude Opus 4.8 audit agent and discovered a vulnerability in the Zcash Orchard shielded pool circuit dating back to 2022, which in testing could generate unlimited counterfeit ZEC without a trace. Developers completed the fix within days, and no theft of coins has been confirmed.Statistics from blockchain analytics firm Chainalysis show that on-chain writes carrying malware instructions and command-and-control information rose from about 2.06 per day to 11.1 per day, an increase of 440%.

Odaily reports that Chainalysis has released its "Crypto Tax Report: Select Country Data," estimating global crypto-related taxable activity at approximately $457 billion, covering trading gains, on-chain income, and digital payments.The report states that it uses on-chain data to map these activities by region and country, providing tax authorities with a geolocated view of potential taxable activity within their jurisdictions. Among these, stablecoin payment flows represent the largest and most globally distributed category. The report also analyzes cross-border channels and their impact on direct and indirect tax obligations, and demonstrates how on-chain intelligence can help tax authorities identify high-value, high-risk wallets to determine enforcement priorities.

Odaily reports: Blockchain analytics firm Chainalysis has released a report stating that hackers are increasingly leveraging open-source artificial intelligence (AI) to implant malware control instructions into on-chain transactions and smart contracts, with such cases surging approximately 440% in less than a year. Data shows that these incidents have risen from roughly 2 per day to approximately 11 per day. Attackers write malicious instructions on-chain to manipulate infected devices into stealing passwords and funds, and redirect assets to designated wallets; since on-chain records cannot be deleted, defense and interception are becoming increasingly difficult.The report notes that state-sponsored hackers from countries such as North Korea and Iran have become the primary drivers of such activity. Open-source models support local independent operation and modification, allowing them to directly bypass cloud-based defenses. However, the public and transparent nature of blockchain also leaves critical evidence for tracing attack infrastructure. (Bloomberg)

Member state tax authorities will begin cross-border exchanges of relevant records from September 30, 2027. The CARF currently covers approximately 14% of potentially taxable on-chain activity globally. (Bitcoin.com News)

Odaily News, The Sandbox has released a post-mortem report on the August 22 vulnerability incident. The report shows that attackers exploited vulnerabilities in contracts related to cross-chain configurations on Base and BNB Smart Chain (BSC), stealing 14,742,341.84 SAND from the Ethereum treasury, accounting for approximately 0.5% of the maximum supply, with an estimated economic impact of approximately $1.4968 million, of which about $987,000 was actually retained by the attackers. The Ethereum mainnet and Polygon network were not affected. Until further notice, please do not purchase or send SAND on Base or BNB Smart Chain. Contracts deployed on Base and BNB Smart Chain have been permanently deactivated and will not be reopened. The Sandbox stated that the team has reported the attacker's wallet address to blockchain analysis firms TRM Labs and Chainalysis, and has communicated directly with relevant exchanges. The Sandbox also announced a compensation plan, which will compensate wallets that legitimately held cross-chain SAND on Base or BSC prior to the incident at a 1:1 ratio in Ethereum SAND. Compensation funds will come from The Sandbox treasury, with no new tokens issued. The claim process will open within the next two weeks and remain open for two weeks.
