U.S. government recovers nearly $500,000 from North Korean hack on Kansas medical facility

The U.S. Department of Justice seized roughly $500,000 in ransom payments that a medical center in Kansas paid to North Korean hackers last year, along with cryptocurrency used to launder the payments, Deputy Attorney General Lisa Monaco said Tuesday.

The hospital quickly paid the attackers, but also notified the FBI, “which was the right thing to do for both themselves and for future victims,” Monaco said in a speech at the International Conference on Cyber Security at Fordham University in New York City.

The notification enabled the FBI to trace the payment through the blockchain, an immutable public record of cryptocurrency transactions.

DARPA-Funded Study Provides Insights into Blockchain Vulnerabilities

Posted by in categories: blockchains, evolution, space

The architecture and evolution of planetary systems are shaped in part by stellar flybys. Within this context, we look at stellar encounters which are too weak to immediately destabilize a planetary system but are nevertheless strong enough to measurably perturb the system’s dynamical state. We estimate the strength of such perturbations on secularly evolving systems using a simple analytic model and confirm those estimates with direct N-body simulations. We then run long-term integrations and show that even small perturbations from stellar flybys can influence the stability of planetary systems over their lifetime. We find that small perturbations to the outer planets’ orbits are transferred between planets, increasing the likelihood that the inner planetary system will destabilize.

Blockchain not just for bitcoin. It can secure and store genomes too

Posted by in categories: biotech/medical, bitcoin, blockchains, chemistry, computing, cryptocurrencies

Blockchain is a digital technology that allows a secure and decentralized record of transactions that is increasingly used for everything from cryptocurrencies to artwork. But Yale researchers have found a new use for blockchain: they’ve leveraged the technology to give individuals control of their own genomes.

Their findings are published June 29 in the journal Genome Biology.

“Our primary goal is to give ownership of genomic data back to the individual,” said senior author Mark Gerstein, the Albert L. Williams Professor of Biomedical Informatics and professor of molecular biophysics and biochemistry, of computer science, and of statistics and .

Generative AI to Help Humans Create Hyperreal Population in Metaverse

Posted by in categories: augmented reality, blockchains, holograms, information science, internet, robotics/AI, virtual reality

In forthcoming years, everyone will get to observe how beautifully Metaverse will evolve towards immersive experiences in hyperreal virtual environments filled with avatars that look and sound exactly like us. Neil Stephenson’s Snow Crash describes a vast world full of amusement parks, houses, entertainment complexes, and worlds within themselves all connected by a virtual street tens of thousands of miles long. For those who are still not familiar with the metaverse, it is a virtual world in which users can put on virtual reality goggles and navigate a stylized version of themselves, known as an avatar, via virtual workplaces, and entertainment venues, and other activities. The metaverse will be an immersive version of the internet with interactive features using different technologies such as virtual reality (VR), augmented reality (AR), 3D graphics, 5G, hologram, NFT, blockchain, haptic sensors, and artificial intelligence (AI). To scale personalized content experiences to billions of people, one potential answer is generative AI, the process of using AI algorithms on existing data to create new content.

In computing, procedural generation is a method of creating data algorithmically as opposed to manually, typically through a combination of human-generated assets and algorithms coupled with computer-generated randomness and processing power. In computer graphics, it is commonly used to create textures and 3D models.

The algorithmic difficulty is typically seen in Diablo-style RPGs and some roguelikes which use instancing of in-game entities to create randomized items. Less frequently it can be used to determine the relative difficulty of hand-designed content to be subsequently placed procedurally, as can be seen with the monster design in Unangband. For example, the designer can rapidly create content, but leaves it up to the game to determine how challenging that content is to overcome, and consequently where in the procedurally generated environment this content will appear. Notably, the Touhou series of bullet hell shooters use algorithmic difficulty. Though the users are only allowed to choose certain difficulty values, several community mods enable ramping the difficulty beyond the offered values.

Researchers Detail How Cyber Criminals Targeting Cryptocurrency Users

Posted by in categories: blockchains, cryptocurrencies, finance

Cybercriminals are impersonating popular crypto platforms such as Binance, Celo, and Trust Wallet with spoofed emails and fake login pages in an attempt to steal login details and deceptively transfer virtual funds.

“As cryptocurrency and non-fungible tokens (NFTs) become more mainstream, and capture headlines for their volatility, there is a greater likelihood of more individuals falling victim to fraud attempting to exploit people for digital currencies,” Proofpoint said in a new report.

“The rise and proliferation of cryptocurrency has also provided attackers with a new method of financial extraction.”

Ethereum Moves Closer to Blockchain Revamp After Milestone Test

Posted by in categories: blockchains, cryptocurrencies, cybercrime/malcode

Ethereum, the world’s most used cryptocurrency blockchain network, passed a milestone test ahead of a highly anticipated technical upgrade without any major glitches.

Developers ran the latest software for the upgrade known as the Merge on Ropsten, which is one of the oldest so-called testnets of the network. The testnets are used by developers to find potential bugs and glitches before moving their applications to the blockchain. While the Merge has been carried out on other testnets earlier this year, Ropsten was seen as providing the most realistic technical environment and the best estimate for the outcome of the final process.

New York just passed a bill cracking down on bitcoin mining — here’s everything that’s in it

Posted by in categories: bitcoin, blockchains, cryptocurrencies, law, security

Following an early morning vote in Albany on Friday, lawmakers in New York passed a bill to ban certain bitcoin mining operations that run on carbon-based power sources. The measure now heads to the desk of Governor Kathy Hochul, who could sign it into law or veto it.

If Hochul signs the bill, it would make New York the first state in the country to ban blockchain technology infrastructure, according to Perianne Boring, founder and president of the Chamber of Digital Commerce. Industry insiders also tell CNBC it could have a domino effect across the U.S., which is currently at the forefront of the global bitcoin mining industry, accounting for 38% of the world’s miners.

The New York bill, which previously passed the State Assembly in late April before heading to the State Senate, calls for a two-year moratorium on certain cryptocurrency mining operations which use proof-of-work authentication methods to validate blockchain transactions. Proof-of-work mining, which requires sophisticated gear and a whole lot of electricity, is used to create bitcoin. Ethereum is switching to a less energy-intensive process, but will still use this method for at least for another few months.

Blockchain pioneers become main target of murderers and extortionists

Posted by in categories: bitcoin, blockchains, business, cryptocurrencies

When reading about the emerging cryptoworld and the new opportunities presented by blockchain technology, you may be enchanted by rags-to-riches stories with billions made overnight, or perhaps be horrified by scams, where the founders of fraudulent projects skip off to Tahiti with their investor’s money. However, it’s doubtful that the first thing that pops into your mind will be grizzly tales of extortion, kidnapping, and even murder. But for blockchain pioneers, falling victim to these horrific crimes is a very real risk that they must be wary about every day.

The explosive profit potential of cryptocurrencies has attracted a myriad of extortionists, scammers, and outright criminals over the years since Bitcoin was first launched in January of 2009. Some developers have had their companies’ reputations damaged by such conmen, and some have ended up beaten, kidnapped, and even killed.

One business that found itself the target of such nefarious opportunists was a Singapore-based company called Skycoin, which is still dealing with the fallout from these attacks to this day. After taking the rather innocuous decision to hire a marketing company to do PR and improve their website, the project and its co-founder found themselves caught in a web of blackmail, deceit, and crime that most people would only encounter in a crime thriller directed by Quentin Tarantino.
