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.

The Bitcoin Sell-Off Is Back, With Ethereum And Ripple’s XRP Bleeding Hard–Here’s Why

Bitcoin has taken a turn for the worse this week, falling sharply as the cryptocurrency sell-off that had gripped market for months the resumes in force—putting to bed hopes that the worst of the so-called crypto winter bear market is over. The bitcoin price has lost some 6% since the weekend, with ethereum down by 11% and ripple, a common name for the XRP digital token, off by 10% over the same period, according to the latest prices on CoinMarketCap, which tracks most major cryptocurrencies.
