A new ransomware gang known as LockFile encrypts Windows domains after hacking into Microsoft Exchange servers using the recently disclosed ProxyShell vulnerabilities.

ProxyShell is the name of an attack consisting of three chained Microsoft Exchange vulnerabilities that result in unauthenticated, remote code execution.

The three vulnerabilities were discovered by Devcore Principal Security Researcher Orange Tsai, who chained them together to take over a Microsoft Exchange server in April’s Pwn2Own2021hacking contest.

The Nevera packs four electric motors that send 1,914 horsepower (1,408 kilowatts) to all four wheels. The car is also wearing Michelin Pilot Sport 4S tires while tipping the scales at 4,733 pounds (2,146 kilograms). It has an MSRP of $2.4 million. The Tesla Model S is far less powerful and cheaper, but it still impresses with its 1,020 hp (760 kW) output, thanks to its three-motor setup. It’s heavier than the Rimac at 4,833 lbs (2,192 kg), though it’s much cheaper at $124,000. Power routes to all four Michelin Pilot Sport 4S tires.

Watch as the Tesla Model S Plaid faces off against the Rimac Nevera hypercar in a series of high-powered EV drag races.

Blockchains work like DNA, says a new study. Its instructions are replicated across thousands of “nodes,” much as DNA is replicated in cells.

The mission is described as the ‘next epic leap forward for civilians’.

Web infrastructure and website security company Cloudflare on Thursday disclosed that it mitigated the largest ever volumetric distributed denial of service (DDoS) attack recorded to date.

The attack, launched via a Mirai botnet, is said to have targeted an unnamed customer in the financial industry last month. “Within seconds, the botnet bombarded the Cloudflare edge with over 330 million attack requests,” the company noted, at one point reaching a record high of 17.2 million requests-per-second (rps), making it three times bigger than previously reported HTTP DDoS attacks.

The probe has made detailed measurements of Venus’s cloudy atmosphere. Could it find life?

The Mercury-bound BepiColombo spacecraft recorded the sound of the solar wind at Venus as it flew just 340 miles (550 kilometers) above the planet’s surface during a maneuver designed to adjust its path.

“Stay safe friends,” astronaut Megan McArthur says.

As parts of the U.S. northeast brace for Hurricane Henri to make landfall in New York today (Aug. 22), astronauts and satellites are tracking the historic storm from space.

The Japan Aerospace Exploration Agency (JAXA) has announced that it has successfully demonstrated the operation of a “rotating detonation engine” for the first time in space. The novelty of the technologies in question is that such systems obtain a large amount of thrust by using much less fuel compared to conventional rocket engines, which is quite advantageous for space exploration.

On July 27 the Japanese agency launched a pair of futuristic propulsion systems into space to carry out the first tests. They were launched from the Uchinoura Space Center aboard the S-520–31, a single-stage rocket capable of lofting a 220 lbs (100 kg) payload well above 186 miles (300 km). After recovering the rocket from the ocean, the JAXA team of engineers analyzed the data and confirmed the success of the mission, which put the new system at an estimated altitude of (146 miles) 234.9 km.

The rotating detonation engine uses a series of controlled explosions that travel around an annular channel in a continuous loop. This process generates a large amount of super-efficient thrust coming from a much smaller engine using significantly less fuel – which also means sending less weight on a space launch. According to JAXA, it has the potential to be a game-changer for deep space exploration.

It’s one of the most profound innovations of our time — and Manhattan-based Australian Kate Crawford wants us to wake up to AI’s inherent risks.
