Xiaohongshu fully acquired the AI travel tool Yuan Zhou Lu Ji

Xiaohongshu fully acquired the AI travel tool Circumference Travel's affiliated company. The latest business information shows that Xiaohongshu Technology Co., Ltd. has become the sole shareholder of Chaochao Shishi Technology (Shanghai) Co., Ltd., with former shareholder Zheng Yifan exiting. Circumference Travel provides a "one-click homework copying" feature, allowing users to paste links of notes from Xiaohongshu and public account travel guides, after which the AI can extract attractions and restaurants, generate a map route, estimate transportation time, and support collaborative itinerary modifications with friends. QuestMobile data shows that in February this year, its monthly active users reached approximately 2.49 million, a year-on-year increase of 384.7%, ranking among the top ten travel service apps, with users aged 25 to 35 accounting for 72.1%.By the end of 2025, the Circumference Travel team had stated that they would not engage in flight and hotel bookings. In September of this year, the app added features for AI querying flight, hotel, and ticket prices, allowing users to directly jump to partner platforms for booking after reviewing their itinerary, and check order status within the app. Last year, Xiaohongshu also acquired the development entity of its AI search product Diandian. Diandian is used to help users find destinations and filter activities, while Circumference Travel can organize promotional notes into executable itineraries and guide users to make bookings.

Hackers claim to have leaked information of over 40,000 employees from the U.S. Department of Homeland Security through Okta, and DDoSecrets has made it public

According to TechCrunch, a hacker claiming to be from the "Department of Peace" has reportedly obtained a large amount of employee data from the Okta single sign-on system used by the Department of Homeland Security (DHS), which was publicly released on Wednesday by the data transparency organization Distributed Denial of Secrets (DDoSecrets) as the "Icepick" dataset. The leaked records exceed 40,000, accounting for about one-fifth of DHS's approximately 220,000 employees, involving names, positions, work emails, phone numbers, and office locations, along with information related to internal system permissions. Among these, approximately 21,000 records belong to Customs and Border Protection (CBP) personnel, while about 10,000 records involve the Immigration and Customs Enforcement (ICE) and its Homeland Security Investigations (HSI), with nearly 1,000 related to the Cybersecurity and Infrastructure Security Agency (CISA).TechCrunch stated that it has verified the authenticity of some of the data, with timestamps indicating that the data was exported around mid-August. The hacker also provided the data to journalist and hacker maia arson crimew, who then forwarded it to DDoSecrets. Okta responded that its systems and data were not breached; a spokesperson for the Department of Homeland Security has not yet responded to requests for comment. The report indicates that this is the third incident of data leakage from the U.S. government that has drawn attention in the past month, following the theft of Federal Bureau of Investigation personnel files and Pentagon personnel data.

first_img Ipsos survey: 22% of Americans have held cryptocurrency, with an annual usage rate remaining steady at 13%

According to a report by Decrypt, a national survey commissioned by the cryptocurrency policy advocacy organization DeFi Education Fund and conducted by Ipsos shows that 22% of American adults have held or used cryptocurrency, up from 18% in 2025, but the usage rate over the past 12 months remains flat at 13%. The survey, conducted from September 8 to 16, interviewed 1,545 adults, with a margin of error of ±2.8 percentage points. The growth almost entirely comes from users who have dropped out: among those who have not used cryptocurrency in the past year, the proportion who had held or used it rose from 5% to 11%; the willingness to purchase in the future also remains flat, with 17% indicating they might hold or use it in the future, compared to 16% last year.In terms of user demographics, the usage rate for men in the past year was 18%, while for women it was 8%, with the former being more than double the latter. Adults under 60 showed a significantly higher usage rate than older individuals. The primary reason for trying cryptocurrency is curiosity (34%), followed by long-term investment (25%). Respondents expressed significant unease about the traditional financial system: only 19% believe it is safe, and 63% think it needs to be upgraded to address cybercrime and AI threats; 60% are concerned about data breaches at large financial institutions, and 54% doubt their ability to withstand AI-driven threats, while 74% indicate that financial privacy is important.This skepticism has not translated into trust in cryptocurrency. Only 4% have high trust in cryptocurrency exchanges, and 5% have high trust in decentralized platforms, while large national banks and credit unions have trust levels of 42% and 48%, respectively. The knowledge gap is also significant: only 2% of Americans are very familiar with DeFi, 6% can identify all four characteristics of cryptocurrency listed in the survey, and 35% are completely uncertain about how to describe cryptocurrency. However, 40% indicate that if DeFi were available, there is at least some possibility they would try it, with over 80% stating they would use it to save money, earn interest, or send money to friends and family; the desire to understand stablecoins and DeFi decreased from 11% to 7% and 8%, respectively.
