Yahoo! Stolen Account More Than 500 Million Former Executives Say Over 1 Billion According to foreign media reports, Yahoo's user accounts leaked due to hacking may be between 1 billion and 3 billion. A former Yahoo executive who is familiar with Yahoo's security department disclosed that relevant data from Yahoo's back-end system shows that Yahoo's user accounts leaked due to hacking have exceeded 500 million in size. The source said that although he is not currently working for Yahoo, he has been in frequent contact with Yahoo's internal staff. He said "I think the number of Yahoo user accounts stolen by hackers is far greater than the company previously disclosed." Yahoo! has stated that the number of user account leaks caused by hacking in 2014 was at least 500 million. However, the aforementioned informed executives estimate that the potential stolen accounts may be between 1 billion and 3 billion. "How they came to this conclusion of 500 million is a mystery," said the person familiar with the matter. 400 Play App Malware Codes on Google Play Store: Mobile Variable Listening Station According to foreign reports, a report released by Trend Micro, a market research organization, revealed that in Google Play, Google’s application store, malicious code was hidden in over 400 apps. These malicious code applications can be used. Infected mobile phones become listening stations, and user sensitive data leaks potential risks at any time. The report said that an app with "DressCode" malicious code was downloaded by users from 100,000 to 500,000 times before it was cleared out of Google Play. Mod GTA 5 for Minecraft PE, as everyone knows, is usually considered as a benign game, but the game contains malicious code that can be used by hackers to build hackers. Control server connection. These servers controlled by hackers can bypass the so-called Network Address Translation (NAT) protection system. Trend Micro has discovered a total of more than 3,000 applications similar to this malicious code, but 400 of them are from Google Play. The latest Nobel Prize prediction list has become popular with gravitational waves and cancer immunotherapy This year's highly regarded Nobel Prize will be announced on October 3rd. The Nobel Prize represents the most advanced science and technology and the future direction that the market is most concerned about. From the “Citation Award†(Nobel Prize-winning prediction vane) released this year, cancer immunotherapy, gravitational waves, and gene editing become physics, respectively. Winning prizes in the fields of science, medicine, and chemistry. In addition, the electromechanically converted nano-energy systems (MEMS sensors) have also become a focus of physics prizes. Last year, Tu Yu won the Nobel Prize in medicine and became the first person in China’s indigenous scientific community. Recently, U.S. authority Thomson Reuters released a forecast list. Among them, Professor Zhang Feng and major contributors to gravitational waves who have made significant contributions to the CRISPR-cas9 gene editing technology are included in the list. New Shepard Rocket of Blue Origin for Escape System Testing According to foreign media reports, as with most detectors, the blue origin company’s rocket also has an escape system. When a problem is detected, the system will quickly eject the manned cabin to a safe place. However, the New Shepard rocket's escape cabin is different from the previous one. The escape system will receive the "most rigorous" test ever next week. Blue Origins Inc. and Amazon.com president Jeff Bezos said that it will launch at 10:50 AM on the 4th of October EDT. The company will deliberately trigger an escape opportunity at the most crucial moment of flight, that is, when the pressure reaches its maximum in 45 seconds after launch. Bezos said that we have tested the thrust escape system, including many ground test and launch platform escape tests, but this upcoming flight escape test is the most difficult. Blue Origins stated that the last manned flight flight escape test was still in the Apollo program. This will be the fifth test flight conducted by New Shepard, but it is only for the second time that Blue Origins has broadcasted the rocket launches in real time. Successful target for the first flight of hydrogen fuel airliner is sky taxi Recently, the low-noise HY4 hydrogen fuel cell four-seat passenger aircraft has recently been successfully tested at Stuttgart Airport, which means that it has made another breakthrough in zero-emission passenger flights. The HY4 wing has a length of 21.36 meters. The two two-seat fuselage are connected together. The propeller is installed between the two fuselage. The advantage of this design is that it can optimize the drive assembly and obtain more total load capacity. Each of the two airframes carries a 9 kg hydrogen storage tank that will provide power to the four cryogenic proton exchange membrane battery packs under the propeller. These batteries then convert hydrogen and oxygen into water and electricity. The battery will power the electric engine in flight through a chemical reaction, and the 21 kWh lithium polymer battery pack will power the aircraft during takeoff and climb. Weak photon human security tester cited disputes Chengdu airport five measures rectification According to the Voice of China's "National News Network," it is reported that the use of "weak photon human security instruments" at railway stations and airports in many places in Sichuan has caused controversy for passenger security. This kind of instrument is essentially X-ray exposure, and the public questioned how such security screening may affect physical health. Chengdu Shuangliu Airport is also using this equipment. It was announced at the airport in the early morning that five measures will be taken to rectify the situation. The Chengdu Environmental Protection Bureau also made it clear that it is properly handling the matter according to regulations. In response to queries from public opinion, Chengdu Airport responded early this morning that it has advised the safety inspection instrument manufacturer to explain it to the community as soon as possible, and set up eye-catching “man-made security inspection channels†and “voluntary rapid security inspection channels†guidance cards at the terminal inspection site. The inspection method can be chosen voluntarily. For special groups such as “old, young, sick, disabled, and pregnantâ€, security personnel will take the initiative to conduct manual inspections.
