Warning Issued After Malware Is Found To Have Hijacked Bitcoin Blockchain

Bitcoin’s blockchain has been hijacked by a new strain of the Glupteba malware that uses the network to resist attacks, cyber security researchers have warned.

The malware uses the bitcoin blockchain to update, meaning it can continue running even if a device’s antivirus software blocks its connection to servers run by the hackers, security intelligence blog Trend Micro reported this week.

The Glupteba malware, first discovered in December 2018, is distributed through advertising designed to spread viruses through script and can steal an infected devices’ browsing history, website cookies, and account names and passwords with this particular variant found to be targeting file-sharing websites.

However, according to researchers, the new version of the malware can also mine the privacy-specialized monero cryptocurrency and threaten the security of Instagram users’ accounts.

The malware uses the Electrum bitcoin wallet to send bitcoin transactions that the attackers use to gain access to systems.

“This technique makes it more convenient for the threat actor to replace command and control servers,” Trend Micro researchers wrote. A command and control server is the centralized computer that issues commands to an infected network of devices.

“If they lose control of a command and control server for any reason, they simply need to add a new bitcoin script and the infected machines obtain a new command and control server by decrypting the script data and reconnecting.”

It’s not the first time the bitcoin blockchain has been taken advantage of by criminals, with German researchers last year discovering child abuse imagery shared via the decentralized network.

by Christian Karam & Vitaly Kamluk The blockchain is the public ledger stacking all bitcoin/altcoins transactions. It is constantly growing as “completed” blocks are automatically added to it with a new set of records. The blocks are added to the blockchain in a linear and chronological order. The blockchain has complete information about the addresses and their balances right from the genesis block to the most recently completed block through the mining process. Depending on the crypto-currency and the implementation of its protocols, there would be a fixed open space, where data can be stored, referenced or hosted on the blockchain within encrypted transactions and their records. This very versatile nature of the blockchain offers great opportunities for future innovation especially in decentralized systems. The research focus revolves around the threat of embedding decentralized chunks of malware on the blockchain by either hosting it or referencing it with cascaded pointers. Transactions and data are encrypted throughout the blockchain networks using different versions of public/private key encryption. Could malware survive eternally inside crypto-transactions? A proof of concept will be explained highlighting the concerns revolving around the “abuse and bloating” of the blockchain while comparing it to previous malware hosting and deployment models. In this talk, INTERPOL will frame the scope of this future threat and provide potential solutions for a threat surrounding the blockchain technology.

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

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 Winklevoss Twins Made A Serious Wall Street Bitcoin Warning

The Winklevoss twins of Facebook-founding fame have long been strong advocates for bitcoin and cryptocurrencies, buying up huge amounts of bitcoin and founding the U.S. Gemini crypto exchange.

The bitcoin price, now back above $10,000 per bitcoin after dipping under the psychological mark earlier this month, has climbed around 200% so far this year, emboldening bitcoin bulls who had feared last year’s bear market could drag on through 2019.

Now, the Winklevoss twins have warned Wall Street banks have been “asleep at the wheel” on bitcoin and cryptocurrencies—something that’s helped bitcoin retail investors.

“Unlike the internet, which you couldn’t buy a piece of, you can actually buy a piece of this new internet of money,” Tyler and Cameron Winklevoss told CNN.

“It’s still a retail-driven market, from day one. And a lot of people have done really well. Wall Street has been asleep at the wheel,” the twins warned.

Bitcoin’s epic 2017 bull run, which saw the bitcoin price soar from under $1,000 per bitcoin at the beginning of the year to almost $20,000 in December, was largely thought to be due to Wall Street and institutional investment could be poised to flow into bitcoin and crypto.

When this investment failed to firmly materialise, the bitcoin price crashed to around $3,000 per bitcoin last year, only to rebound in 2019 as a result of technology companies taking an interest in bitcoin and crypto.

“We had to invest because we were afraid of missing out, we couldn’t miss out on this future,” the twins added.

Meanwhile, Tyler and Cameron Winklevoss earlier said they are open to partnering with Facebook chief executive Mark Zuckerberg on the social media giant’s libra cryptocurrency project after it was revealed they have been in talks about joining the Libra Association.

The newly-created, independent governance consortium for Facebook’s planned token currently counts 28 founding members but is expected to swell to around 100 by the time of libra’s launch next year.

And just like U.S. dollars and other government-issued currencies, BTC has found use cases in illicit transactions. Whether it be purchasing questionable goods or otherwise, the flagship cryptocurrency has found a place……..
