Police officer Guo Tingyu from the Cybersecurity Division of the Qingshan Branch of the Wuhan Public Security Bureau participated in the investigation of Hubei's first virtual currency theft case. By tracking the flow of funds and analyzing the code of fake wallets, he identified and dismantled a cryptocurrency theft gang involved in over 100 million yuan in illicit funds, with all five suspects arrested.The gang induced users to download a counterfeit virtual currency wallet app to steal coins, with a total download count of over ten thousand. Guo Tingyu also participated in the investigation of multiple virtual currency-related criminal cases.

According to the Hong Kong Wen Wei Po, the Hong Kong police have disclosed the resolution of a cross-border phone scam case, where a criminal group impersonated mainland officials, specifically targeting mainland students studying in the UK and Australia.The scammers falsely claimed that the victims were involved in criminal cases such as money laundering and demanded their "cooperation in the investigation." They instructed the victims to travel to Hong Kong to purchase gold grains in multiple transactions at jewelry stores as "collateral," with each transaction not exceeding HKD 120,000 to evade the registration system of gold shops. The group members then collected and transferred the stolen goods. The gold grains were subsequently melted down into gold bars or exchanged for cash and virtual currency. The police have currently received a total of 7 related cases, involving approximately HKD 7 million, with the highest single case loss reaching HKD 1.6 million.

Project Eleven today awarded the Q-Day prize to researcher Giancarlo Lelli, who successfully derived a 15-digit elliptic curve private key from a public key using publicly accessible quantum hardware, marking the largest scale demonstration of its kind to date, a 512-fold increase from the 6-digit demonstration in September 2025.Lelli used a variant of Shor's algorithm for the elliptic curve discrete logarithm problem, which is the mathematical foundation of the Bitcoin signature scheme, with the awarded hardware featuring approximately 70 qubits. Currently, no known quantum computer can crack real Bitcoin wallets, and the security of Bitcoin's 256-bit elliptic curve remains far beyond current quantum capabilities. Notably, Google lowered its resource estimates for ECDLP-256 on March 31 and set a target for the migration to quantum cryptography after 2029, followed by Cloudflare, and the UK's NCSC also set migration milestones from 2028 to 2035.On-chain data shows that approximately 6.93 million BTC are at potential quantum risk due to exposed public keys. The Bitcoin community has proposed BIP 360 and BIP 361 to promote the migration to quantum-resistant output types, but the coordination challenges of a decentralized network remain the biggest hurdle.

Polymarket stated on platform X, "Last month, we released enhanced market integrity rules to combat insider trading. When we discover users trading on government confidential information, we refer the matter to the Department of Justice and cooperate with their investigation. Polymarket does not tolerate insider trading, and today's arrests prove that this system is effective."The arrest mentioned by Polymarket refers to the U.S. federal authorities arresting a special forces soldier this Thursday who was involved in the arrest of Venezuelan President Maduro. This soldier is suspected of profiting over $400,000 by betting on Maduro's ouster. Sources say federal investigators believe this commando placed over $33,000 in bets on the prediction market Polymarket just hours before President Trump announced the capture of Maduro in January.

The U.S. Department of the Treasury's Office of Foreign Assets Control (OFAC) announced sanctions against Cambodian Senator Kok An, accusing him of controlling "fraud parks" across the country, defrauding American victims through cryptocurrency investment scams.According to a statement released by OFAC on Thursday, in addition to Kok An, 28 other individuals and entities have been added to the sanctions list, all believed to be connected to his fraud network. This network is accused of luring victims into sending cryptocurrency assets under the guise of "high return investments." This action follows a raid by Cambodian police on two scam centers in the border city of Poipet. Previously, Kok An had been accused of operating scam bases in the area. OFAC stated that scammers typically gain victims' trust by establishing "friendships" or "romantic relationships," then guide them to participate in so-called cryptocurrency investment platforms, thereby defrauding them of funds, with the total amount involved reaching millions of dollars.It is noteworthy that some individuals involved in the scam activities are themselves victims of human trafficking, forced to engage in illegal activities under threats of violence. OFAC pointed out that these scam centers are often located in casinos or repurposed office parks, used not only for money laundering but also as bases for defrauding American citizens and committing human rights violations. Additionally, regulators have simultaneously shut down over 500 fraudulent website domains used for cryptocurrency investment scams, indicating that the U.S. crackdown on related criminal activities is intensifying.

According to Xinhua News Agency, the Office of the Central Anti-Corruption Coordination Group for International Fugitive Pursuit and Cross-Border Corruption Governance held a meeting to launch the "Sky Net 2026" operation. In this operation, the National Supervisory Commission will lead a special action for recovering losses from overseas pursuit of duty-related crimes, the Ministry of Public Security will carry out the "Fox Hunt" special operation, the People's Bank of China, in conjunction with the Ministry of Public Security, will conduct a special action to prevent and combat the use of offshore companies and underground banks to transfer stolen funds abroad, and the Central Organization Department, together with the Ministry of Public Security and the National Immigration Administration, will manage the positions of "naked officials" and address issues related to public officials violating regulations when traveling abroad.

Bitcoin security researcher and Ethereum Foundation researcher Justin Drake published a discussion on the timeline for quantum computing to crack Bitcoin.Justin Drake believes that the findings of Google's quantum AI white paper are conservative. "By 2032, quantum computers will have at least a 10% chance of recovering the secp256k1 ECDSA private key from leaked public keys. While it still feels unlikely that a cryptographically relevant quantum computer (CRQC) will emerge before 2030, it is undoubtedly time to start preparing."Justin Drake also stated that achieving commercially viable Bitcoin proof of work through Grover's algorithm will not happen in the short term. "We are talking about decades, or even centuries later. This observation should help shift the focus of the discussion onto ECDSA and Schnorr. As an unofficial Bitcoin security researcher, I still believe that Bitcoin proof of work has failed due to the reduction in the security budget."

Google's research shows that future quantum computers may only need 9 minutes to crack Bitcoin private keys, which is 1 minute shorter than the average block time of 10 minutes for BTC.The study warns that memory pool attacks could become a real threat and urges an immediate transition to post-quantum cryptography.

According to reports from the Ping An Tianjin Binhai public account, the police in Chenzhou, Hunan have cracked a new type of investment fraud case involving virtual currency, intercepting 7 packages of gold related to the fraud and seizing 310 grams of gold.The police traced the leads and found that these intercepted express deliveries were all part of a scheme where criminals, under the guise of investment and financial management, lured victims to purchase gold offline and then send it to a designated address. The illicit funds were then circulated multiple times through virtual currency exchanges and transfers to overseas accounts. The police remind that this new type of investment fraud has become a new trap, and the gold involved in the case is currently being gradually returned to the victims, with the investigation ongoing.

According to Cointelegraph, the Criminal Assets Bureau of the Irish National Police has announced that it has successfully cracked one of the 12 Bitcoin wallets associated with a convicted drug dealer, retrieving 500 Bitcoins worth over 35 million dollars.The wallet owner is Clifton Collins, who was sentenced to five years in prison in 2017 for cultivating and selling cannabis. Collins purchased 6,000 Bitcoins with drug trade proceeds between 2011 and 2012, storing them across 12 wallets, with the keys printed on an A4 sheet of paper and hidden in a fishing rod case, which were later lost when his landlord cleared the house.Earlier today, it was reported that the Irish drug dealer deposited 500 BTC into Coinbase after nearly 10 years, worth 35.44 million dollars.

According to Solid Intel, the FBI, in conjunction with the Thai police, seized approximately 8,000 mobile phones and froze about $580 million in cryptocurrency assets in an operation targeting scams against Americans.

According to the Hong Kong Commercial Daily, the Hong Kong police launched an operation codenamed "Thunder Drum," targeting a fraud group that claims to offer low-interest loans and collects deposits in cryptocurrency. Within two days, they arrested 3 men and 3 women (aged between 29 and 63) across various districts in Hong Kong on suspicion of conspiracy to commit fraud. Some suspects have connections to organized crime, and the operation is still ongoing.Since November 2025, this fraud group has been randomly calling victims, posing as bank employees to promote low-interest loans. They lure victims to a fake office rented under a shell company in Central to sign contracts and require them to pay deposits as proof of assets. The methods of payment include cash, bank transfers to dummy accounts, and cryptocurrency payments, with the latter primarily targeting older individuals or those unfamiliar with technology.A total of 13 victims are involved, with diverse backgrounds, some holding associate or master's degrees, including businessmen and company owners, with total losses amounting to approximately 5 million Hong Kong dollars. The police seized various documents and computers as evidence at the scene.

According to the Jinan Daily, Li Weiwei, a female police officer from the Economic Investigation Unit of the Dezhou Public Security Bureau in Shandong Province, China, optimized her investigative methods by tracking the flow of funds transaction by transaction during the analysis of a telecom fraud case.After detailed analysis, Li Weiwei discovered a new type of criminal model that combines "traditional underground banks + virtual currency," which is more concealed and harder to trace. After several days of continuous effort, she ultimately identified 12 main criminal suspects, over 100 financial accounts, and 6 virtual currency wallet addresses. Together with the special investigation team, she created a clear organizational structure chart and a flow chart of the funds, legally freezing the assets involved in the case, successfully solving Dezhou's first underground bank case involving virtual currency.

The People's Bank of China, together with relevant departments, has maintained a high-pressure crackdown on illegal financial activities such as illegal fundraising, speculative trading of virtual currencies, and underground banks.In the next step, the People's Bank of China will orderly resolve risks in key areas to prevent financial risks and maintain financial stability, continue to carry out a high-pressure crackdown on illegal financial activities in collaboration with industry regulators and law enforcement departments such as the police, closely monitor and assess the impact of external shocks, and utilize macro-prudential and financial stability policy tools to timely weaken or block risk contagion.

According to Caixin, the Hong Kong Customs announced the recent bust of two suspected air cargo smuggling cases involving precious metals at Hong Kong International Airport, seizing approximately 168 kilograms of suspected gold flakes and about 285 kilograms of suspected silver flakes, with an estimated total market value of around HKD 230 million. Based on the market value of the smuggled goods, this is the largest case of smuggling precious metals recorded by Customs.According to the Hong Kong Import and Export Ordinance, smuggling is a serious crime. Anyone who imports or exports goods not listed on the manifest, upon conviction, can be fined up to HKD 2 million and imprisoned for 7 years.

Quantum computing company PsiQuantum has launched the construction of a million-qubit quantum computing facility in Chicago. PsiQuantum co-founder Peter Shadbolt shared photos from the construction site on the X platform on Thursday, stating that 500 tons of steel have been erected in six days.The company previously announced in September that it had raised $1 billion to build the facility, in collaboration with chip manufacturer Nvidia, aiming to make quantum computing commercially viable to support the next generation of AI supercomputers. Scientists say that the computational power of a million qubits is equivalent to that of hundreds of billions of ordinary computers, enough to crack Bitcoin's encryption technology. Bitcoin developers are currently discussing whether to take immediate action against quantum threats through a hard fork.A preprint scientific paper released last month suggests that breaking a 2048-bit key would require about 100,000 qubits, while Bitcoin encryption uses a 256-bit key. The largest quantum computer currently comes from the California Institute of Technology, with a scale of 6,100 qubits. PsiQuantum co-founder Terry Rudolph stated in July that the company has no plans to use quantum computers to derive private keys from public keys.Research by crypto asset management firm CoinShares in February of this year pointed out that only 10,230 Bitcoins are simultaneously vulnerable to quantum threats, with wallet addresses' encryption keys publicly visible, amounting to approximately $728 million at current market prices.
