WannaCry On the Move? Bitcoin Crime Evolves in a Multi-Blockchain World

admin Monero, Ransomware, WannaCry 0 Comments

First, there was the theft – then the coins stood still. For the past 10 weeks, three bitcoin address containing more than $140,000-worth of the cryptocurrency has been given more scrutiny than possibly any others on the blockchain. Now held by the hacker or hackers behind the WannaCry ransomware attack, the funds were sent by victims from more than 150 countries in an attempt to unlock their computers from the malicious encryption software. But last week, something stirred – and increments of $20,000-worth of bitcoin began moving into seven new addresses. Slowly, the three addresses that had held the attention of the world began to empty. The question was, where were the coins headed? That the subject would gain such attention perhaps isn’t surprising. At the time of the incident in May, WannaCry attracted global headlines, and bitcoin got a share of the blame. As bitcoin’s value grew over the course of the year, and as it attracted a new class of investors, the incident emerged as a black mark – the latest reminder of how the technology can be used to nefarious ends. “There’s an implication that [blockchains] are well-suited for criminal activity,” said Andrew Poelstra, a mathematician at Blockstream. “Because blockchains make it cheaper to …

Quantum Computing Key to Secure Blockchain: Carnegie Mellon Chief Scientist

admin Blockchain News, Quantum Computers, Security 0 Comments

While Blockchain technology is a relatively new innovation, it has been steadily gaining recognition recently. According to Gregory Shannon, Chief Scientist of Carnegie Mellon University, Blockchain is a technology that has now found its way out of the encryption community and into other sectors as well. He states that it will be ideal for the economic systems around the world and also the healthcare and medical industry. Quantum computing effects Although encryption of data is a rather safe mode of transferring data through several networks, quantum computing could allow a third party to break through the encryption which can be an actual threat to encryption technology such as Blockchain technology. However, Shannon believes that by the time quantum computing can be used for breaking encryptions, they would have already made a quantum-resistant protocol. To do this, they must also make use of quantum computing.  As long as the encryption is kept secure by the development of these security measures, data can be transferred without much risk of a breach. With Blockchain technology impacting so many parts of the globe, it is essential to make sure that the technology is very secure and safe because it contains information and important data of many people from around the world.

The Dark Web is More Like a Set of Dark Silos

The Dark Web is More Like a Set of Dark Silos

  The dark web is not nearly as social a place as the world wide web, researchers find. Researchers recently conducted a comprehensive charting of the dark web, starting with the central hubs of “.Onion” domains, and created an algorithm to scan links from each site. They found 7,178 sites. 25,104 links connected all of these sites together. Those sites which did not have links incoming could not be found. The researchers – Virgil Griffith, Yang Xu, Carlo Ratti – discovered that 87% of dark web sites do not link to other sites. To account for websites regularly appearing and disappearing, the authors only included sites that responded to their crawlers. “In our analysis, before pruning nonresponding domains, we found a graph of 13,117 nodes and 39,283 edges. After pruning, we have a graph of 7,178 nodes and 25,104 edges (55% and 64% respectively). In all results, we refer to this graph pruned of nonresponding domains as simply ‘the darkweb graph’”. The researchers, through their research, determined the dark web is no web. But, rather, a set of  “dark silos,” according to the preliminary paper posted on ArXiv this week. The researchers performed a second crawl to collect instances of …

Who doesn’t really know the man Ross Ulbricht? Well, it turns out a lot of you folks don’t so let’s begin with a two line introduction. Ross Ulbricht is the man behind “Dread Pirate Roberts”, you may ask what on earth is Dread Pirate Roberts. Basically, Ross Ulbricht was convicted (a while ago) for operating a Silk Road drug marketplace online. He used the pseudonym Dread Pirate Roberts for the obvious privacy reasons. This fact, however, isn’t news. The real news is that attorneys who are representing Ross Ulbricht have revealed that they have managed to unearth concrete evidence that someone (no one knows the name of this someone at the moment) accessed the Dread Pirate Roberts account by logging in at the Silk Road online forums while their client was in jail. The incidence, attorneys for Ross Ulbricht claim, took place about six weeks after Ross Ulbricht was arrested by law enforcement agencies for running an online drug marketplace. Additionally, it was also revealed that Ross Ulbricht was in the custody of federal authorities when that certain someone accessed his account on the Silk Road online drug marketplace. However, there is still some doubt about the authenticity of the evidence …

Many Bitcoin users have compared the digital currency to settlement networks like Visa. However, one important technical aspect which separates Bitcoin from the rest is security. In early November, Tesco Bank suspended all user transactions after 20,000 clients lost an estimated $700 per account. A study published in the academic journal IEEE Security & Privacy, led by Newcastle University’s Mohammed Ali, revealed that an attack called “Distributed Guessing Attack” could have been used in the breach of Tesco Bank accounts. Essentially, the Distributed Guessing Attack (DGA) is a method which allows hackers and criminals to gain access to Visa credit card numbers as well as their security codes within six seconds by a process of elimination. Ali, the author of the study, stated that the process of elimination with credit card networks like Visa is made possible as they permit an unlimited number of guesses for each card data field. Ali says: “The unlimited guesses, when combined with the variations in the payment data fields make it frighteningly easy for attackers to generate all the card details one field at a time.” “Each generated card field can be used in succession to generate the next field and so on.

The holiday season is a time for shopping for gifts, spending time with family and for some, hacking into the San Francisco subway system. In fact, many, many computer systems in San Francisco were hacked this past weekend. So many, in fact, that the entire subway system has been left free to use until the computer problem is resolved. The answer will come in the form of Bitcoin, as this is what the culprits have demanded in return for putting the computer system back online. Over 2000 local computer systems affected A strain of a computer malware, known as HDDCryptor, hit 2,112 computers within the San Francisco Municipal Transportation Agency, according to correspondence with the ransomware’s masters. This has affected the railway system starting on Friday evening, continuing throughout Saturday, and as of Sunday night, there has been no news of a resolution. CBS affiliate KPIX in San Francisco, says sources inside of the city’s transit agency told them on Saturday that the system was hacked days ago. Payment kiosks are out of service and cards can not be purchased. “There’s no impact to the transit service, but we have opened the fare gates as a precaution to minimize customer …
