Jupyter trojan: Newly discovered malware stealthily steals usernames and passwords

A newly uncovered trojan malware campaign is targeting businesses and higher education in what appears to be an effort to steal usernames, passwords and other private information as well as creating a persistent backdoor onto compromised systems.

Jupyter infostealer has been detailed by cybersecurity company Morphisec who discovered it on the network of an unnamed higher education establishment in the US. It’s thought the trojan has been active since May this year.

The attack primarily targets Chromium, Firefox, and Chrome browser data, but also has additional capabilities for opening up a backdoor on compromised systems, allowing attackers to execute PowerShell scripts and commands, as well as the ability to download and execute additional malware.

The Jupyter installer is disguised in a zipped file, often using Microsoft Word icons and file names that look like they need to be urgently opened, pertaining to important documents, travel details or a pay rise.

Newly discovered primate in Myanmar ‘already facing extinction’

In a rare find, scientists have identified a new species of primate, a lithe tree-dweller living in the forests of central Myanmar with a mask-like face framed by a shock of unruly grey hair.

The Popa langur — named for an extinct volcano home to its largest population, some 100 individuals — has been around for at least a million years, according to a study detailing the find, published Wednesday in Zoological Research.

But with only 200 to 250 left in the wild today, experts will recommend that the leaf-eating species be classified as “critically endangered”.

“Just described, the Popa langur is already facing extinction,” said senior author Frank Momberg, a researcher at Flora & Fauna International (FFI), in Yangon.

Throughout its range, the lithe monkey with chalk-white rings around its eyes is threatened by hunting and habitat loss, he said in a statement.

The first evidence of the new

Newly discovered primate ‘already facing extinction’

A monkey that is new to science has been discovered in the remote forests of Myanmar.

The Popa langur, named after its home on Mount Popa, is critically endangered with numbers down to about 200 individuals.

Langurs are a group of leaf-eating monkeys that are found across south east Asia.

The newly described animal is known for its distinctive spectacle-like eye patches and greyish-coloured fur.

It is at risk from habitat loss and hunting.

Scientists have long suspected there might be a new species in Myanmar, based on DNA extracted from the droppings of wild monkeys, but evidence has been hard to find.

With very little information to go on, they turned to historical specimens stored in natural history museums in London, Leiden, New York and Singapore.

Early explorers to Burma collected the monkey specimens, which had

Using radar and other ice-penetrating instruments, scientists have detected a “fossil lakebed” preserved beneath the Greenland ice sheet, in what is the first discovery of its kind.

Now a basin smothered by a gigantic sheet of ice, this former lake once measured 2,740 square miles (7,100 square kilometers) in size, which is an area comparable to Rhode Island and Delaware combined, according to a Columbia University press release. In some places it got as deep as 820 feet (250 meters), and it was fed by more than a dozen streams. Doesn’t sound very Greenland-ish today, but this is how the island likely looked millions of years ago.

Eventually, however—and we’re not entirely sure when—this lake got covered in ice, never to see daylight ever again. New research

By analyzing data from astronomical surveys, Japanese astronomers have detected a new, extremely variable quasi-stellar object (QSO), or quasar. The newly found object, designated SDSS J125809.31+351943.0, brightened in optical band for 4.0 mag over three decades, which means that it was one of the largest quasar brightening events so far recorded. The finding is reported in a paper published November 3 on arXiv.org.


Quasars are active galactic nuclei of very high luminosity, emitting electromagnetic radiation observable in radio, infrared, visible, ultraviolet and X-ray wavelengths. They are among the brightest and most distant objects in the known universe, and serve as fundamental tools for numerous studies in astrophysics as well as cosmology. For instance, quasars have been used to investigate the large-scale structure of the universe and the era of reionization. They also improved our

On This Day in Space: Nov. 6, 1572: Tycho supernova discovered

On Nov. 6, 1572, the German astronomer Wolfgang Schulër observed a supernova with his bare eyes. He spotted the exploding star in the constellation Cassiopeia. It was as bright as Venus and could even be seen during the day.

Supernova Photos: Great Images of Star Explosions

Astronomers were really confused, because it looked like a star just appeared out of nowhere. Schulër may have been the first to see it, but the Danish astronomer Tycho Brahe is widely credited for the discovery. Brahe studied it in detail and wrote a whole book about this so-called “new star.” It then became known as “Tycho’s Star.”

Bizarre molten planet discovered with lava ocean, supersonic winds

Scientists say they have possibly identified a lava world so dramatic that it might boast a thin regional atmosphere of vaporized rock where it is closest to its star.

That exoplanet is called K2-141b and was originally discovered in 2017. The world is about half again as big as Earth but orbits so close to its star, which is one class smaller than our own, that it completes several loops each Earth-day with the same surface permanently facing the star. Now, scientists predict those factors mean that two-thirds of the surface of K2-141b is permanently sunlit — so much so that not only is part of the world covered in a lava ocean, but some of that rock may even evaporate away into the atmosphere.

Our galaxy may be teeming with rogue planets, gravitationally unbound to any star. An international team of scientists, led by Polish astronomers, has announced the discovery of the smallest Earth-sized free-floating planet found to date.


Over 4,000 extrasolar planets have been discovered to date. Although many of the known exoplanets do not resemble those in our solar system, they have one thing in common—they all orbit a star. However, theories of planet formation and evolution predict the existence of free-floating (rogue) planets, gravitationally unattached to any star. Indeed, a few years ago, Polish astronomers from the OGLE team from the Astronomical Observatory of the University of Warsaw provided the first evidence for the existence of such planets in the Milky Way. Writing in Astrophysical Journal Letters, OGLE astronomers

Skyscraper-sized reef discovered in Australia [Video]

Scientists have discovered a massive detached coral reef taller than the Empire State Building in Australia’s Great Barrier Reef.

It’s the first discovery of its kind in over a century and the reef is healthy and thriving.

Footage captured by scientists shows clown fish paddling between vibrant peach and pink coral; a colourful scene found last week by a team from James Cook University.

Marine Scientist Dr Robin Beaman led the mission:

“That’s it was a real eye-opener to bring the R.O.V. up over the ledge, literally climb onto the summit, and then peer around in the warm photic water, warm photic zone to see all the fish and coral and sharks there. So a very healthy coral ecosystem on this type of top of a 500 metre tall reef. It’s not something you discover every day.”

The nearly mile-long structure was named the “blade reef” for its sharp peak,

Newly discovered Triassic lizard could float underwater to pick off prey

Some 240 million years ago, the Triassic predator Brevicaudosaurus jiyangshanensis skulked, nearly motionless, in the sea — and researchers found clues in its skeleton that could explain its unusual hunting methods.

Scientists at the Chinese Academy of Scientists in Beijing and Canadian Museum of Nature in Ottawa studied two skeletons discovered in a thin layer of limestone in two quarries in southwest China. The most complete skeleton, measuring just under 60 centimeters long, was found in a quarry in Jiangshan.

Experts identified the 240 million-year-old remains as a previously unknown species of nothosaurs: small-headed marine reptiles with fangs, flipper-like limbs and a long neck. Usually, nothosaurs had a longer tail, which experts think was used for propulsion — but the newly discovered reptile had a short and flat tail.

The reptile’s forelimbs were more developed than its hind limbs, and could have played a role in helping the animal to … Read More
