Was SHA-256 cracked? Don’t buy into retraction!

Posted by in categories: bitcoin, cryptocurrencies, encryption, government, hacking, internet, mathematics, military, privacy, security, software

SHA-256 is a one way hashing algorithm. Cracking it would have tectonic implications for consumers, business and all aspects of government including the military.

It’s not the purpose of this post to explain encryption, AES or SHA-256, but here is a brief description of SHA-256. Normally, I place reference links in-line or at the end of a post. But let’s get this out of the way up front:

One day after Treadwell Stanton DuPont claimed that a secret project cracked SHA-256 more than one year ago, they back-tracked. Rescinding the original claim, they announced that an equipment flaw caused them to incorrectly conclude that they had algorithmically cracked SHA-256.

All sectors can still sleep quietly tonight,” said CEO Mike Wallace. “Preliminary results in this cryptanalytic research led us to believe we were successful, but this flaw finally proved otherwise.

Researchers Have Issued A Serious Bitcoin Security Warning

Posted by in categories: bitcoin, cryptocurrencies, security

Bitcoin and cryptocurrency adoption has failed to live up to expectations over recent years and fears around scams, fraud, and theft have not helped.

The bitcoin price, after its epic 2017 bull run, slumped last year– though has rebounded in 2019, climbing back above $10,000 per bitcoin.

Now, researchers have warned a staggering four out of the first five results returned when asking Google for a “bitcoin qr generator” led to scam websites–potentially furthering negative public perception around bitcoin and cryptocurrency.

Can Bitcoin Transactions be Made Private?

Posted by in categories: bitcoin, cryptocurrencies, privacy

The blockchain is public, yet a Bitcoin wallet can be created anonymously. So are Bitcoin transactions anonymous? Not at all…

Each transaction into and out of a wallet is a bread crumb. Following the trail is trivial. Every day, an army of armchair sleuths help the FBI. That’s how Silk Road was brought down.

The problem is that some of that money eventually interacts with the real world (a dentist is paid, a package shipped or a candy is purchased at a gas station). Even if the real-world transaction is 4 hops before or after hitting the “anonymous” wallet, it creates a forensic focal point. Next comes a tax man, an ex-spouse or a goon.

The first article linked below addresses the state of tumblers (aka “mixers”). They anonymize an open network by obfuscating the trail of bread crumbs.

Something Very Strange Is Going On With Bitcoin And BTC Google Searches

Posted by in categories: bitcoin, cryptocurrencies

Bitcoin and cryptocurrency prices are well known to be closely tied to media and general public interest –-though that could be changing.

The bitcoin price has been climbing so far this year, rising some 200% since January, though has recently plateaued at around $10,000 per bitcoin after peaking at more than $12,000 in June.

Now, it appears Google searches for bitcoin and BTC, the name used by traders for the bitcoin digital token, could be being manipulated–-possibly in order to move the bitcoin price.

The Race to Own One Bitcoin

Posted by in categories: bitcoin, cryptocurrencies, economics, finance

Owning one full bitcoin is becoming a recognized attainment goal. And thereby hangs a tale.

Is it just a numbers game? Isn’t the unit a bit arbitrary and meaningless?…

The logistics and the math are compelling. I recognized the importance of reaching this personal milestone more than 8 years ago. But I was a nobody. No one cared. Then, in April 2019, we started to see articles in legitimate venues about this concept—and articulated in exactly this way. I borrowed the title of this post from this article in Medium.

Who Says So?

Police hijack a botnet and remotely kill 850,000 malware infections

Posted by in categories: cryptocurrencies, cybercrime/malcode

In a rare feat, French police have hijacked and neutralized a massive cryptocurrency mining botnet controlling close to a million infected computers.

The notorious Retadup malware infects computers and starts mining cryptocurrency by sapping power from a computer’s processor. Although the malware was used to generate money, the malware operators easily could have run other malicious code, like spyware or ransomware. The malware also has wormable properties, allowing it to spread from computer to computer.

Since its first appearance, the cryptocurrency mining malware has spread across the world, including the U.S., Russia, and Central and South America.

Immortality, Cryogenics and UBI: How The Crypto Rich Influence Science

Posted by in categories: biotech/medical, cryptocurrencies, life extension, science

The rise of cryptocurrency is changing the philanthropic world by causing the redistribution of wealth from old money to visionary innovators and early tech adopters. The new crypto rich invest their donations by supporting scientific research in groundbreaking fields that may one day enable humanity to cure aging, reverse death and completely change the relationship between work and income.

Examining the record of donations made by the crypto rich reveals a pattern of support for goals that others may feel belong in the pages of science fiction novels. Having benefited greatly from recognizing the potential of peer to peer electronic cash earlier than the masses, it is no surprise that they have great optimism in the power of technology to radically change our lives for the better.

Employees connect nuclear plant to the internet so they can mine cryptocurrency

Posted by in categories: cryptocurrencies, internet, nuclear energy, security

Ukrainian authorities are investigating a potential security breach at a local nuclear power plant after employees connected parts of its internal network to the internet so they could mine cryptocurrency.

The investigation is being led by the Ukrainian Secret Service (SBU), who is looking at the incident as a potential breach of state secrets due to the classification of nuclear power plants as critical infrastructure.

Investigators are examining if attackers might have used the mining rigs as a pivot point to enter the nuclear power plant’s network and retrieve information from its systems, such as data about the plant’s physical defenses and protections.
