On December 3, *The Economic Observer* reported that Qian Zhimin—the mastermind of a 60,000 Bitcoin money laundering case—fled with a laptop featuring a built-in cryptocurrency wallet. After multiple searches, British police seized several electronic devices, including phones, computers, and USB drives. One USB drive held a photo of a page from Qian’s notebook; notably, the page appeared to have been torn out before the seizure. The photo recorded the startup password for the black laptop, several mnemonic words (such as “number + love”), and number-related hints—enabling access to the previously seized Bitcoins.

On December 3rd, the SlowMist Security Team published a security advisory detailing a phishing attack targeting a user. The attacker transferred the user’s account owner permissions, leaving the victim unable to revoke authorizations or access their assets—even though funds appeared normal, they were no longer under the user’s control. - Over $3 million in assets were stolen. - An additional $2 million locked in a DeFi protocol (initially untransferable) was later rescued with support from the respective DeFi platform. This was not a traditional “authorization theft”; instead, the attacker seized core owner permissions, blocking the victim from sending transactions, revoking access, or managing DeFi assets. The attacker exploited two counterintuitive tactics to trick the user into signing: 1. Wallets typically simulate transaction execution during signing and display fund changes—but the attacker’s crafted transaction had no fund shifts, hiding malicious activity. 2.

December 3rd — Cointelegraph reports the number of registered foundation companies in the Cayman Islands has surged 70% year-over-year. As of end-2024, the total exceeded 1,300, with over 400 new registrations in the first five months of 2025. Cayman foundations are emerging as the go-to legal framework for DAOs, supporting treasury management, intellectual property (IP) holding, and compliance needs. At least 17 foundation treasuries have surpassed $1 billion in assets. Notably, the OECD’s Common Reporting Standard (CRS) will take formal effect in 2026. Cayman will require crypto service providers involved in transactions, custody, and similar activities to conduct due diligence and submit reports. However, treasury protocols focused solely on asset holding and passive foundations are expected to be exempt from mandatory reporting. The OECD CRS aims to combat tax evasion tied to crypto asset transactions via a standardized automatic information exchange mechanism.
