Covid: White hat bounty hackers become millionaires - BBC News

Covid: White hat bounty hackers become millionaires - BBC News

Hackers earned a record $40m (£28m) in 2020 for reporting software flaws via a leading bug bounty reporting service.

HackerOne said nine hackers made more than $1m each after it flagged their findings to affected organisations.

One Romanian man, who only started bug-hunting two years ago, saw his total earnings to date top $2m. The UK's top-earning hacker made $370,000 last year.

Significant jump in number of hackers reporting vulnerabilities to companies

The number of white hat hackers who find security vulnerabilities and warn companies about them, usually to earn a bug bounty, increased by 63% in 2020, according to the latest annual Hacker report .

The number of ethical hackers reporting bugs or vulnerabilities to enterprises has increased by 143% since 2018, demonstrating that hackers and IT security teams are working together much more frequently to manage cyber threats.  

The report, published on 9 March by security platform HackerOne, also found that more than one-third (38%) of hackers have spent more time hacking since the start of the pandemic, with many zeroing in on emerging threats that have arisen from the shift to remote working and organisations' consequent digital transformations.

Hackers act differently if accessing male or female Facebook profiles | New Scientist

Cybercriminals seem to behave differently depending on the age and gender listed on the Facebook accounts they hack into, although questions have been raised about the ethics of the study that has revealed this.

Jeremiah Onaolapo at the University of Vermont and his colleagues, including some at Facebook, created 1008 realistic Facebook accounts, populating them with fake information, photos and posts. They then leaked the login details for 672 of these accounts on websites used by hackers to trade compromised credentials, including Pastebin, Paste.org.ru, and the dark web site Stronghold.

This Fingertip for Robots Uses Magnets to ‘Feel’ Things | WIRED

Imagine, if you will, the home robot of the future. It picks clutter off the floor, sweeps, and does the dishes. And it has to do so perfectly : If the robot has an error rate of just 1 percent, it will drop one dish out of a hundred. Totally unacceptable. In no time, your floor would be covered in shards and the robot would get stuck in a sad, vicious feedback loop, dropping dishes and sweeping them up and dropping more dishes, ad infinitum.

It's just not feasible, though, to try to replicate the wildly complicated human system of touch—so Yan's team kinda replicated it. The "skin" of their robotic fingertip is made of a flexible magnetized film, which generates a magnetic field within the device. The supporting "bone" of the finger is a circuit board, which is studded with sensors that monitor the magnetic field.

Robotics and automation have already transformed how certain industries work, like the auto industry. But the technology is still being realized in many other sectors, and some of those businesses–like retail, food, and healthcare–became more reliant on automation and robotics during the pandemic. That change is likely permanent. The fact is that there are still many, many jobs that machines can do better than humans.

Long-distance space travel: addressing the radiation problem – Physics World

A team of US and Netherlands-based scientists has published a review paper highlighting ways to protect astronauts from the negative cardiovascular health impacts associated with exposure to space radiation during long-distance space travel.

In an effort to address these limitations, researchers based at the University Medical Center (UMC) Utrecht, Leiden University Medical Center, Radboud University and the Technical University Eindhoven in the Netherlands, as well as Stanford University School of Medicine and Rice University in the US, have carried out an exhaustive review of existing evidence to establish what we know about the cardiovascular risks of space radiation.

The World's First Space Hotel Will Open in 2027 — and You Can Even Buy a Vacation Home There

The world's first space hotel will feature a gourmet restaurant, bar, villas for purchase, and more.

Space tourism is no longer the stuff of science fiction — it's just around the corner. Aside from private missions to space, like Inspiration4 and DearMoon , in which members of the general public will spend a few days in a SpaceX vehicle circling the Earth and moon, respectively, there are also a few space hotels in the works.

Taking its cue from science fiction films like "2001: A Space Odyssey" and "Interstellar," Voyager Station will create artificial gravity using centrifugal force. The hotel will take on the shape of a Ferris wheel, spinning to simulate gravity in its pods. Though its form might be unusual compared to Earth hotels, its rooms and amenities will be largely familiar to regular travelers.

Building a better spacesuit for a trip to Mars - Sciworthy

The year 2021 is surely an exciting one for all space science enthusiasts, given the success of UAE's HOPE mission and the Perseverance rover mission by NASA. However, the first step towards colonizing Mars would be to send astronauts to the red planet.

To achieve this, we would need a space shuttle for transport and a spacesuit for protection from cosmic radiation . Investigators of the present study employed biological as well as physical principles to investigate materials for an intravehicular (worn inside space vehicles) spacesuit and a "storm shelter" that would minimize radiation exposure to astronauts during a mission to Mars.

Perseverance Takes Its First Drive on Mars - ExtremeTech

Perseverance is about the size of a sub-compact car, weighing more than 2,000 pounds on Earth. Even on Mars, that’s a big robot. Like Curiosity, this rover used a rocket-powered sky crane to execute a soft landing on Mars . NASA wanted to make sure Perseverance was in full working order before driving it anywhere. It also needed a software update, which NASA completed in late February.

With the housekeeping done, NASA pumped the gas on March 4th. It took about 33 minutes for Perseverance to complete the maneuvers — accuracy is much more important than speed at a distance of 142 million miles (about 230 million kilometers). First, the rover drove forward 13 feet. Then, it turned in place 150 degrees before backing up another eight feet.

Study Shows Mars' Early Climate Was Intermittently Warm  | | SBU News

The authors, led by Robin Wordsworth of Harvard University, point out that reconciling the geology of Mars with models of atmospheric evolution remains a major challenge because Martian geology is characterized by past evidence for episodic surface liquid water and geochemistry indicating a slow and intermittent transition from wetter to drier and more oxidizing surfaced conditions.

"Mars was intermittently warmed when its atmospheric composition was altered by the input of gases derived from volcanism and meteorite impactors. These climate optima allowed water to flow across the surface, forming rivers and lakes, and the rocks and minerals we associate with water on Mars," explains Hurowitz, associate professor in the Department of Geosciences in the College of Arts and Sciences.

If you're fascinated by the idea of looking back in time, just look up at the sky. If you stare at the moon, you're seeing the orb as it was around 1.3 seconds ago. Pointing your telescope at Mars? You're seeing it as it was around 20 minutes ago. That's how long it takes for light to travel those vast distances across the solar system. With a big-enough telescope, you can see light from the earliest moments of the universe, some 13 billion years ago.

Establishing the origin of solar-mass black holes and the connection to dark matter

Surprisingly, LIGO has recently observed a 2.6 solar-mass black hole candidate (event GW190814, reported in Astrophysical Journal Letters 896 (2020) 2, L44). Assuming this is a black hole, and not an unusually massive neutron star, where does it come from?

Solar-mass black holes are particularly intriguing, since they are not expected from conventional stellar evolution astrophysics. Such black holes might arise in the early Universe ( primordial black holes ) or be "transmuted" from existing neutron stars. Some black holes could have formed in the early universe long before the stars and galaxies formed. Such primordial black holes could make up some part or all of dark matter.

A Scientist Made An Artificial Black Hole In The Lab, And You Won’t Believe What Happened

As it turns out, the truth is both less and more than meets the eye. The article above was eventually edited to better reflect the truth that, alas, we have not yet found a way to create objects so massive that even light cannot escape them. Instead, physicist [Jeff Steinhauer] and colleagues at the Technion-Israel Institute of Technology have developed an acoustic model of black holes, which is what was used to observe the equivalent of Hawking radiation for the first time.

That’s where [Steinhauer]’s sonic black holes come in. In these experiments, phonons, packets of mechanical vibrations that stand in for photons, are trapped in a fast-moving stream of fluid. The point in the stream where its speed straddles the local speed of sound is the equivalent to a real black hole’s event horizon; phonons inside that boundary can never escape.

How the Milky Way–Andromeda black hole merger may play out | Science News

The supermassive black holes at the centers of the Milky Way and Andromeda galaxies are doomed to engulf each other in an ill-fated cosmological dance.

Astronomers have long known that Andromeda is on a collision course with our galaxy ( SN: 5/31/12 ). But not much has been known about what will happen to the gargantuan black holes each galaxy harbors at its core. New simulations reveal their ultimate fate.

The galaxies will coalesce into one giant elliptical galaxy — dubbed "Milkomeda" — in about 10 billion years. Then, the central black holes will begin orbiting one another and finally collide less than 17 million years later , researchers propose February 22 at arXiv.org and in an earlier paper published in Astronomy & Astrophysics . Just before the black holes smash into each other, they'll radiate gravitational waves with the power of 10 quintillion suns ( SN: 2/11/16 ).

Study shows that the GW190521 event could be explained by primordial black holes

"Our paper originated from the observation by the LIGO/Virgo collaboration of the so-called GW190521 event, the merger of two black holes," Antonio Riotto, one of the researchers who carried out the study, told Phys.org. "The more massive black hole turns out to be in the so-called mass gap, that is, in a range of masses where astrophysical arguments are deficient in explaining the astrophysical nature of such a black hole.

To examine the possibility that a signal is associated with the so-called primordial black hole scenario, one can compute the rate at which two black holes of primordial origin merge (i.e., their merger rate) to produce a gravitational wave signal. Subsequently, researchers must compare this prediction to the merger rate that would be needed to explain the signal observed.

Scientists create a sonic black hole in the lab, confirm Stephen Hawking's theory

Physicists in Israel have devised a black hole analogue — only, rather than being a gravitational fortex that doesn’t allow light to escape, this particular object is a sonic black hole that doesn’t allow sound waves to escape. In the process, the researchers measured the long-theorized Hawking radiation, with important consequences for physics.

A black hole is a region of spacetime where gravity pulls so strongly that even light cannot get out once it crosses a point of no return, known as the event horizon — but you probably knew that already. What may be new to you is that almost 50 years ago, Stephen Hawking proposed a more nuanced view whereby black holes can also generate light.

NASA is Considering a Radio Telescope on the Far Side of the Moon - Universe Today

The University of Colorado Boulder and Lunar Resources Inc. have just won NASA funding to study the possibility of building a radio telescope on the far side of the Moon. The project, called FarView , would harvest building materials from the Lunar surface itself, and use robotic rovers to construct a massive, intricate network of wires and antennas across 400 square kilometers.

Radio telescopes work best in isolation. On Earth, if radio telescope operators want to ‘hear’ the sky without interference, they need to establish enormous exclusion zones around the telescope where cellphones, wi-fi, and even the spark-plugs from gasoline cars are banned. FarView proposes to put a telescope in the quietest place we can think of, away from Earthlings and our noisy gadgets.

In fact, we have created an entirely new color solution – Natural Color Calibration with Hasselblad – that will now serve as our new standard for color calibration for future OnePlus smartphone camera systems."

Talking about improvements in camera technology is one of the cornerstones of any modern smartphone's launch; OnePlus is no different to the rest. At the flagship end of the market many of the technical specifications are within a few percentage points of each other; the visual element is one that can be used to easily demonstrate the progress a smartphone manufacturer has made.

Inside the Alabama stop on Blue Origin's journey to the moon - al.com

A Blue Origin employee stands beside a "pathfinder" model of the company's planned lunar lander at the company's plant in Huntsville, Ala. Blue Origin is leading a team competing to be part of the space agency's return to the moon but is also planning its own commercial future there.

Blue Origin's rocket engine plant in Huntsville, Ala., is the size of three city blocks. Objects on one side can be larger – much larger - than they appear from the other side.

Watch the Moon and 3 Planets Line Up at Dawn

It's easy enough to spot the moon, but it can be much harder to figure out which of the dots in the night sky are the planets. You see a particularly bright object and wonder, if it's a planet, a particularly luminous star, or perhaps, a plane. Well, over the next three days, identifying the planets will be considerably simpler than usual, thanks to the fact that just before dawn, the moon will line up with Mercury, Jupiter and Saturn. Here's what to know.

Jupiter, the most brilliant morning planet, outshines Saturn by some 12 times and Mercury by 7 times. Although Mercury is a touch brighter than Saturn, Saturn will probably be the easier of these two worlds to see, as Saturn rises first, followed by Jupiter and then Mercury. Mercury is buried most deeply in the glare of morning twilight, but try aiming binoculars at Jupiter to glance at Mercury below Jupiter.
