These Are The Most Prevalent Forms Of Cyber Crime

Owed in part to the pandemic-induced increased shift from offline to online, cyber attacks have become a lucrative avenue for criminals in recent years. 

As Florian Zandt reports, Statista experts estimate global losses of $7.1 trillion in 2022 compared to 2019’s $1.2 trillion, with crypto exchange and protocol hacks by prolific groups like the state-affiliated North Korean hacking team Lazarus dramatically increasing in the years 2021 and 2022 according to Chainalysis. While the number of hacks and the damage caused has been on a constant uptick, the types of cyber attacks have shifted dramatically in the past five years.

In 2017, roughly 42 percent of recorded cyber crimes were connected to non-payment or non-delivery.

This category includes purchases made via fraudulent online stores that never materialize and promised payments never arriving.

Personal data breaches and phishing scams constituted an additional 28 percent, while identity theft, credit card fraud and other cyber attacks had a relatively low share in all reported cyber crimes.

Five years later, phishing has become the most prevalent cyber attack. This past year, more than half of criminal online activity was connected to this long-running type of cyber crime.

AI-enabled brain implant helps patient regain feeling and movement

Keith Thomas from New York was involved in a driving accident back in 2020 that injured his spine’s C4 and C5 vertebrae, leading to a total loss in feeling and movement from the chest down. Recently, though, Thomas had been able to move his arm at will and feel his sister hold his hand, thanks to the AI brain implant technology developed by the Northwell Health’s Feinstein Institute of Bioelectronic Medicine. 

The research team first spent months mapping his brain with MRIs to pinpoint the exact parts of his brain responsible for arm movements and the sense of touch in his hands. Then, four months ago, surgeons performed a 15-hour procedure to implant microchips into his brain — Thomas was even awake for some parts so he could tell them what sensations he was feeling in his hand as they probed parts of the organ. 

While the microchips are inside his body, the team also installed external ports on top of his head. Those ports connect to a computer with the artificial intelligence (AI) algorithms that the team developed to interpret his thoughts and turn them into action. The researchers call this approach “thought-driven therapy,” because it all starts with the patient’s intentions. If he thinks of wanting to move his hand, for instance, his brain implant sends signals to the computer, which then sends signals to the electrode patches on his spine and hand muscles in order to stimulate movement. They attached sensors to his fingertips and palms, as well, to stimulate sensation. 

Thanks to this system, he was able to move his arm at will and feel his sister holding his hand in the lab. While he needed to be attached to the computer for those milestones, the researchers say Thomas has shown signs of recovery even when the system is off. His arm strength has apparently “more than doubled” since the study began, and his forearm and wrist could now feel some new sensations. If all goes well, the team’s thought-driven therapy could help him regain more of his sense of touch and mobility. 

While the approach has a ways to go, the team behind it is hopeful that it could change the lives of people living with paralysis. Chad Bouton, the technology’s developer and the principal investigator of the clinical trial, said:

“This is the first time the brain, body and spinal cord have been linked together electronically in a paralyzed human to restore lasting movement and sensation. When the study participant thinks about moving his arm or hand, we ‘supercharge’ his spinal cord and stimulate his brain and muscles to help rebuild connections, provide sensory feedback, and promote recovery. This type of thought-driven therapy is a game-changer. Our goal is to use this technology one day to give people living with paralysis the ability to live fuller, more independent lives.”

Babies who have DNA from 3 different people born in the U.K.

Britain’s fertility regulator on Wednesday confirmed the births of the U.K.’s first babies created using an experimental technique combining DNA from three people, an effort to prevent the children from inheriting rare genetic diseases.

The Human Fertilization and Embryology Authority said fewer than five babies have been born this way in the U.K. but did not provide further details to protect the families’ identities. The news was first reported by the Guardian newspaper.

In 2015, the U.K. became the first country to adopt legislation regulating methods to help prevent women with faulty mitochondria — the energy source in a cell — from passing defects on to their babies. The world’s first baby born using the technique was reported in the U.S. in 2016.

Twitter Algorithm Reveals Tool For Government Intervention

A researcher claims to have found a tool allowing for government intervention in Twitter’s algorithm, upon Elon Musk’s decision to allow the algorithm to become open sourced to the public.

Breitbart reports that Musk honored his promise on Friday by releasing a portion of Twitter’s recommendation algorithm on the website GitHub, where computer programmers often go to share and collaborate on work dealing with open-source code.

Web developer Steven Tey then claimed to have discovered a particular mechanism within the code that allows the U.S. government to make changes to the website’s algorithm.

“When needed, the government can intervene with the Twitter algorithm. In fact, @TwitterEng (Twitter Engineering) even has a class for it – ‘GovernmentRequested,” Tey tweeted, including a link to the code on GitHub.

Upon purchasing Twitter for $44 billion in October, Musk vowed to increase transparency and loosen restrictions on certain speech and accounts that had been imposed by previous leadership. One of his goals was to make the algorithm open source for public viewing; he later said that “our ‘algorithm’ is overly complex & not fully understood internally,” and that “people will discover many silly things, but we’ll patch issues as soon as they’re found!”

In addition, Tey discovered that the algorithm takes such factors into account as following-to-follower ratio when determining which users to promote; users with a low number of followers but a high amount of followed accounts would be negatively affected.

Humans will achieve immortality in eight YEARS, says former Google engineer who has predicted the future with 86% accuracy

A former Google engineer has made a stark realization that humans will achieve immortality in eight years – and 86 percent of his 147 predictions have been correct.

Ray Kurzweil spoke with the YouTube channel Adagio, discussing the expansion in genetics, nanotechnology, and robotics, which he believes will lead to age-reversing ‘nanobots.’ 

These tiny robots will repair damaged cells and tissues that deteriorate as the body ages and make us immune to diseases like cancer.

The predictions that such a feat is achievable by 2030 have been met with excitement and skepticism, as curing all deadly diseases seems far out of reach.

Kurzweil was hired by Google in 2012 to ‘work on new projects involving machine learning and language processing,’ but he was making predictions in technological advances long before.

In 1990, he predicted the world’s best chess player would lose to a computer by 2000, and it happened in 1997 when Deep Blue beat Gary Kasparov.  

Kurzweil made another startling prediction in 1999: he said that by 2023 a $1,000 laptop would have a human brain’s computing power and storage capacity.

“Mini Antlers” Grown On Mice Heads After Scientists Implant Deer Cells

Scientists have grown “mini-antlers” on mice by inserting deer genes into the mouse genome, according to a new paper. The results suggest that mammals that have lost the ability to regenerate organs may still contain some regenerative genes, and that it may be possible to harness the rapid growth of antlers in other applications. 

Growing at 2.75 centimeters (around 1 inch) per day, antlers are one of the fastest regenerating tissues in the animal kingdom and offer a perfect look at how mammals can regenerate cells on a regular basis. Antlers are especially interesting because mammals in general have lost the ability to regenerate organs and most other tissues, so a large appendage that regularly regrows offers unparalleled insight into how regenerative medicine for bones could work.  

In the pursuit of regenerative medicines, Chinese researcher Toa Qin and colleagues took a deep dive into the mechanics behind the antlers of Sika deer, which regrow every year before they are shed. In doing so, they created a regenerative “atlas” of Sika deer antlers, isolating multiple single cells and genes that are critical in the development of the antler tissue. 

Ten days before the antlers were shed, the researchers identified one type of stem cell that was highly active in the regeneration, and these remained with the antlers a short time after shedding. However, by day five post-shedding, a new subtype of stem cells had emerged. 

After identifying multiple stages of growth, the team took the stem cells with the most regrowth potential (which proved to be from shed antlers around five days old) and cultured them in a Petri dish before implanting them into the head of mice.

Researchers launched a solar geoengineering test flight in the UK last fall

Last September, researchers in the UK launched a high-altitude weather balloon that released a few hundred grams of sulfur dioxide into the stratosphere, a potential scientific first in the solar geoengineering field, MIT Technology Review has learned.

Solar geoengineering is the theory that humans can ease global warming by deliberately reflecting more sunlight into space. One possible means is spraying sulfur dioxide in the stratosphere, in an effort to mimic a cooling effect that occurs in the aftermath of major volcanic eruptions. It is highly controversial given concerns about potential unintended consequences, among other issues.

The UK effort was not a test of or experiment in geoengineering itself. Rather, the stated goal was to evaluate a low-cost, controllable, recoverable balloon system, according to details obtained by MIT Technology Review. Such a system could be used for small-scale geoengineering research efforts, or perhaps for an eventual distributed geoengineering deployment involving numerous balloons.

The “Stratospheric Aerosol Transport and Nucleation,” or SATAN, balloon systems were made from stock and hobbyist components, with hardware costs that ran less than $1,000.

Scientists create mice with two fathers after making eggs from male cells

Scientists have created mice with two biological fathers by generating eggs from male cells, a development that opens up radical new possibilities for reproduction.

The advance could ultimately pave the way for treatments for severe forms of infertility, as well as raising the tantalising prospect of same-sex couples being able to have a biological child together in the future.

“This is the first case of making robust mammal oocytes from male cells,” said Katsuhiko Hayashi, who led the work at Kyushu University in Japan and is internationally renowned as a pioneer in the field of lab-grown eggs and sperm.

Hayashi, who presented the development at the Third International Summit on Human Genome Editing at the Francis Crick Institute in London on Wednesday, predicts that it will be technically possible to create a viable human egg from a male skin cell within a decade. Others suggested this timeline was optimistic given that scientists are yet to create viable lab-grown human eggs from female cells.

Previously scientists have created mice that technically had two biological fathers through a chain of elaborate steps, including genetic engineering. However, this is the first time viable eggs have been cultivated from male cells and marks a significant advance. Hayashi’s team is now attempting to replicate this achievement with human cells, although there would be significant hurdles for the use of lab-grown eggs for clinical purposes, including establishing their safety.

“Purely in terms of technology, it will be possible [in humans] even in 10 years,” he said, adding that he personally would be in favour of the technology being used clinically to allow two men to have a baby if it were shown to be safe.

“I don’t know whether they’ll be available for reproduction,” he said. “That is not a question just for the scientific programme, but also for [society].”

Scientists have revived a ‘zombie’ virus that spent 48,500 years frozen in permafrost

Warmer temperatures in the Arctic are thawing the region’s permafrost — a frozen layer of soil beneath the ground — and potentially stirring viruses that, after lying dormant for tens of thousands of years, could endanger animal and human health.

While a pandemic unleashed by a disease from the distant past sounds like the plot of a sci-fi movie, scientists warn that the risks, though low, are underappreciated. Chemical and radioactive waste that dates back to the Cold War, which has the potential to harm wildlife and disrupt ecosystems, may also be released during thaws.

“There’s a lot going on with the permafrost that is of concern, and (it) really shows why it’s super important that we keep as much of the permafrost frozen as possible,” said Kimberley Miner, a climate scientist at the NASA Jet Propulsion Laboratory at the California Institute of Technology in Pasadena, California.

Permafrost covers a fifth of the Northern Hemisphere, having underpinned the Arctic tundra and boreal forests of Alaska, Canada and Russia for millennia. It serves as a kind of time capsule, preserving — in addition to ancient viruses — the mummified remains of a number of extinct animals that scientist have been able to unearth and study in recent years, including two cave lion cubs and a woolly rhino.

The reason permafrost is a good storage medium isn’t just because it’s cold; it’s an oxygen-free environment that light doesn’t penetrate. But current day Arctic temperatures are warming up to four times faster than the rest of the planet, weakening the top layer of permafrost in the region.

To better understand the risks posed by frozen viruses, Jean-Michel Claverie, an Emeritus professor of medicine and genomics at the Aix-Marseille University School of Medicine in Marseille, France, has tested earth samples taken from Siberian permafrost to see whether any viral particles contained therein are still infectious. He’s in search of what he describes as “zombie viruses” — and he has found some.

Pentagon, FBI Collaborated On AI, Facial Recognition Tech For Federal Agencies, Documents Show

The Department of Defense (DOD) and the FBI collaborated on an artificial intelligence-driven facial recognition technology program provided to at least six federal agencies and a Pentagon agency that supports civilian police forces, The Washington Post reported.

The facial recognition software could be used to identify individuals whose features were captured by drones and CCTV cameras, the Post reported, citing documents obtained through a Freedom of Information Act request as part of an ongoing lawsuit by the American Civil Liberties Union (ACLU) filed against the FBI. The documents reveal federal authorities were more deeply involved in development of the technology than was previously known, sparking concerns over Americans’ privacy rights.

“Americans’ ability to navigate our communities without constant tracking and surveillance is being chipped away at an alarming pace,” Democratic Sen. Ed Markey of Massachusetts told the Post. “We cannot stand by as the tentacles of the surveillance state dig deeper into our private lives, treating every one of us like suspects in an unbridled investigation that undermines our rights and freedom.”
