Representations of virtual cryptocurrencies are seen in this illustration taken November 28, MOSCOW, Jan 20 Reuters - Russia's central bank on Thursday proposed banning the use and mining of cryptocurrencies on Russian territory, citing threats to financial stability, citizens' wellbeing and its monetary policy sovereignty. The move is the latest in a global cryptocurrency crackdown as governments from Asia to the United States worry that privately operated and highly volatile digital currencies could undermine their control of financial and monetary systems. Russia has argued for years against cryptocurrencies, saying they could be used in money laundering or to finance terrorism.

Here’s the truth about the crypto miner that comes with Norton Antivirus
The Australian government has just recognized digital currency as a legal payment method. Since July 1, purchases done using digital currencies such as bitcoin are exempt from the country's Goods and Services Tax to avoid double taxation. As such, traders and investors will not be levied taxes for buying and selling them through legal exchange platforms. Japan, which legitimized bitcoin as a form of payment last April, already expects more than 20, merchants to accept bitcoin payments.
Other countries are joining the bandwagon, albeit partially: businesses and some of the public organizations in Switzerland, Norway , and the Netherlands. In a recent study , unique, active users of cryptocurrency wallets are pegged between 2.
But what does the acceptance and adoption of digital currencies have to do with online threats? A lot, actually. As cryptocurrencies like bitcoin gain real-world traction, so will cybercriminal threats that abuse it. But how, exactly? What does this mean to businesses and everyday users? Cryptocurrency is an encrypted data string that denotes a unit of currency. It is monitored and organized by a peer-to-peer network also known as a blockchain, which also serves as a secure ledger of transactions, e.
Unlike physical money, cryptocurrencies are decentralized, which means they are not issued by governments or other financial institutions. Cryptocurrencies are created and secured through cryptographic algorithms that are maintained and confirmed in a process called mining, where a network of computers or specialized hardware such as application-specific integrated circuits ASICs process and validate the transactions.
The process incentivizes the miners who run the network with the cryptocurrency. Bitcoin, for instance, was created by Satoshi Nakamoto pseudonym and released in as open-source code. Blockchain technology made it all work, providing a system where data structures blocks are broadcasted, validated, and registered in a public, distributed database through a network of communication endpoints nodes.
While bitcoin is the most famous cryptocurrency, there are other popular alternatives. This resulted in the development of Ethereum Classic, based the original blockchain, and Ethereum, its upgraded version via a hard fork. There are also other notable cryptocurrencies: Litecoin, Dogecoin, Monero. Litecoin is a purportedly technical improvement of Bitcoin that is capable of faster turnarounds via its Scrypt mining algorithm Bitcoin uses SHA The Litecoin Network is able to produce 84 million Litecoins—four times as many cryptocurrency units issued by Bitcoin.
Monero is notable for its use of ring signatures a type of digital signature and CryptoNote application layer protocol to protect the privacy of its transactions—amount, origin, and destination. Dogecoin, which was initially developed for educational or entertainment purposes, was intended for a broader demographic. Capable of generating uncapped dogecoins, it also uses Scrypt to drive the currency along. Given their nature, they are more secure from fraud and identity theft as cryptocurrencies cannot be counterfeited, and personal information is behind a cryptographic wall.
Unfortunately, the same apparent profitability, convenience, and pseudonymity of cryptocurrencies also made them ideal for cybercriminals, as ransomware operators showed. The increasing popularity of cryptocurrencies coincide with the incidences of malware that infect systems and devices, turning them into armies of cryptocurrency-mining machines. Cryptocurrency mining is a computationally intensive task that requires significant resources from dedicated processors, graphics cards, and other hardware.
While mining does generate money, there are many caveats. Cryptocurrencies are mined in blocks; in bitcoin, for instance, each time a certain number of hashes are solved, the number of bitcoins that can be awarded to the miner per block is halved.
Since the bitcoin network is designed to generate the cryptocurrency every 10 minutes, the difficulty of solving another hash is adjusted. And as mining power increases , the resource requirement for mining a new block piles up. Payouts are relatively small and eventually decrease every four years—in , the reward for mining a block was halved to Consequently, many join forces into pools to make mining more efficient.
Profit is divided between the group, depending on how much effort a miner exerted. Bad guys turn to using malware to skirt around these challenges. To offset this, cryptocurrency-mining malware are designed to zombify botnets of computers to perform these tasks. Cryptocurrency-mining malware employ the same modus operandi as many other threats—from malware-toting spam emails and downloads from malicious URLs to junkware and potentially unwanted applications PUAs.
In January , a vulnerability in Yahoo! In , the threat crossed over to Android devices as Kagecoin , capable of mining bitcoin, litecoin, and dogecoin. The same was done to an old Java RAT that can mine litecoin. All exploit vulnerabilities. These threats infected devices and machines and turned them into monero-mining botnets. Cryptocurrency-mining malware steal the resources of infected machines, significantly affecting their performance and increasing their wear and tear.
An infection also involves other costs, like increased power consumption. The most prevalent of these attacks we saw were:. Information theft and system hijacking are also daunting repercussions. These attacks can also be the conduit from which additional malware are delivered. In April , a variant of Mirai surfaced with bitcoin-mining capabilities.
Over the first three quarters of , we detected a bitcoin-mining zombie army made up of Windows systems, home routers, and IP cameras. From January 1 to June 24, , we also observed different kinds of devices that were mining bitcoin, although our telemetry cannot verify if these activities were authorized.
We found that machines running Windows had the most bitcoin mining activities, but also of note are:. Cryptocurrency-mining malware can impair system performance and risk end users and businesses to information theft, hijacking, and a plethora of other malware.
And by turning these machines into zombies, cryptocurrency malware can even inadvertently make its victims part of the problem. There is no silver bullet for these malware, but they can be mitigated by following these best practices:.
Proactively monitoring network traffic helps better identify red flags that may indicate malware infection. Original design and equipment manufacturers also play vital roles in securing the ecosystems they run in.

What To Know About Cryptocurrency and Scams
According to security experts at AdGuard, the four sites involved in the crypto-jacking schemes are Openload, Streamango, Rapidvideo and OnlineVideoConverter. Those sites are raking in outrageous amounts of money while visitors are busy streaming or converting videos. Openload, one of the most popular streaming sites, has an estimated million visitors per month. Videos from Openload are often embedded on other sites and, in many cases, the mining script loads when videos are launched.
Mastering Bitcoin by
Cryptocurrency is a type of digital currency that generally only exists electronically. There is no physical coin or bill unless you use a service that allows you to cash in cryptocurrency for a physical token. You usually exchange cryptocurrency with someone online, with your phone or computer, without using an intermediary like a bank. Bitcoin and Ether are well-known cryptocurrencies, but there are many different cryptocurrency brands, and new ones are continuously being created. People use cryptocurrency for quick payments, to avoid transaction fees that regular banks charge, or because it offers some anonymity.

Making it all the sweeter is the fact Dragan pays nothing for electricity, used in abundance in such energy-demanding operations involving complex computer calculations to verify transactions. His decision came after authorities in Kosovo announced on January 4 a blanket ban on cryptocurrency mining amid an energy crisis in the Southeastern European country of some 1. Kosovar police have carried out raids in recent days, confiscating hundreds of high-tech devices used in cryptocurrency mining. Economy Minister Artane Rizvanolli described the action as an "emergency measure" due to the crisis, although experts have questioned whether the government has such a right as Kosovo has no law regulating cryptocurrency mining. In December , Kosovo announced a day state of emergency to deal with the energy crunch exacerbated by a shutdown at one of the country's two coal-fired power plants, forcing Pristina to import power. Energy prices have soared across Europe amid a spike in demand for natural gas as economies recover from the COVID pandemic and fresh tensions with Russia, which supplies one third of Europe's gas. Moscow has rejected European accusations that it has reduced gas deliveries amid reports it has massed tens of thousands of troops and military hardware on the border with Ukraine, sparking fears of a fresh invasion there. Until recently, Kosovo boasted some of Europe's cheapest electricity rates, making cryptocurrency mining especially attractive.

Even in Kazakhstan, Bitcoin Can’t Escape Geopolitics
By Matthew Sparkes. Bitcoin is a digital currency which operates free of any central control or the oversight of banks or governments. Instead it relies on peer-to-peer software and cryptography. A public ledger records all bitcoin transactions and copies are held on servers around the world. Anyone with a spare computer can set up one of these servers, known as a node. Consensus on who owns which coins is reached cryptographically across these nodes rather than relying on a central source of trust like a bank.

Financially motivated threat actors will continue to use malware infections to deploy cryptocurrency mining software for as long as it remains profitable. Compared to complete loss of availability caused by ransomware and loss of confidentiality caused by banking trojans or other information stealers, the impact of unauthorized cryptocurrency mining on a host is often viewed as more of a nuisance. However, the cumulative effect of large-scale unauthorized cryptocurrency mining in an enterprise environment can be significant as it consumes computational resources and forces business-critical assets to slow down or stop functioning effectively. Furthermore, the deployment and persistence of unauthorized cryptocurrency mining software in an environment reflects a breakdown of effective technical controls.
