Cryptominers flooding GitHub—and other cloudy dev services

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.

205 Open Source Mining Software Projects

You are all set to mine the most profitable coins and maximise your profits using MultiPoolMiner. Use config. New: Now you can run this miner on any stratum based pool. Monitors crypto mining pools in real-time in order to find the most profitable for your machine. Controls any miner that is available via command line. This project was created to understand how cryto-currency miners work. For a while, I have understood at a high-level what miners do but the best way for me to really understand was to implement it myself. I read the source code for geth to understand how difficulty is implemented and how hashrate was computed. I use sha Library and program to parse and forward HAProxy logs.

Mining is the new black

April 6, report. The Record, the news branch of the threat intelligence company Recorded Future, has reported that GitHub is currently looking into multiple attacks against its cloud infrastructure. These attacks have enabled cybercriminals to exploit and implant the company's servers for use in illegal crypto-mining operations. In progress since Fall of , these attacks utilize a GitHub feature called GitHub Actions which allow users to automatically initiate tasks and workflows following a certain triggering event within one of their GitHub repositories.

Mine Bitcoins with Cgminer On Ubuntu

Our client is an investor building large cryptocurrency mining facilities in multiple locations. Instead of being dependent on an external, public infrastructure, the client needed to build a private, stable and easy to manage mining pool within a very short period of time. After examining the available options and consulting the client's requirements, we decided that the best solution would be to use pool. Although the software we chose met the requirements of the project, we had to make significant changes to the source code , as it supported the older version of BitCoin core and there were significant differences in the RCP for the target version. Our team has also designed and implemented all the back office tools, as well as a public portal for end users, using technologes such as Python , Django and ReactJS.

Bitcoin Mining is Bad for the World: The Limited Options for Addressing the Problem

Before getting started, obviously Cgminer has to be installed in the system. What it does is download the necessary packages to compile, change the directory to src to install cgminer, clone the cgminer from github to local system, again change the directory to cgminer, prepare the build for compilation, and finally compile the source codes. It may be necessary to use sudo in front of the commands, if an error is promoted asking the administrative privilege. There are a wide variety of wallets available for storing bitcoins, and thus it might be hard to find a suitable one. So, this tutorial uses this lightweight, simple client known as electrum. The following steps teach you how to setup and configure electrum for having your own personal bitcoin wallet. This dash is equivalent to Windows start menu in Windows family.

Can Bitcoin's Hard Cap of 21 Million Be Changed?

Beware of websites with cryptominer embedded as it could impact your computer speed while you lend your CPU resources to help mine cryptocurrency. You may have noticed that certain websites put significant load on your CPU and slow it down. Aside from the possibility that you may not have the best hardware, the slowdown could be due to a JavaScript miner embedded in the website.

The complexity of the modern software development process and its reliance on large community-maintained codebases introduces a risk for developers to inadvertently include malicious code into the project. The implications can be severe: in many cases, it can mean a complete takeover of the developed program or device by an attacker. Attackers attempt to generate this scenario in several ways, among them trying to introduce malicious or vulnerable code into open-source projects and using Typosquatting — adding malicious code into software repositories such as PyPI and npm under names which could be included in a project by mistake such as misspelled names of legitimate software packages. In this blog post, we present our own additional research done on top of a novel detection by Sonatype, where a few PyPI packages were detected as malicious packages, packing a crypto-miner payload that mines Ethereum or Ubiq for the attacker. The typosquatting attack flow of the malicious published packages can be summarized in the following way:.

Cryptojacking with JavaScript

The main problem with a distributed transaction log is how to avoid inconsistencies that could allow someone to spend the same bitcoins twice. The solution in Bitcoin is to mine the outstanding transactions into a block of transactions approximately every 10 minutes, which makes them official. Conflicting or invalid transactions aren't allowed into a block, so the double spend problem is avoided. Although mining transactions into blocks avoid double-spending, it raises new problems: What stops people from randomly mining blocks? How do you decide who gets to mine a block? How does the network agree on which blocks are valid?

Have you wondered what mining Bitcoin and other cryptocurrencies involve, and how you can get yourself some crypto tokens without having to buy them at an exchange? The rapid increase in the prices of crypto coins like Bitcoin, Ether, and Dogecoin in the first half of this year led to many people wanting to get involved in the crypto ecosystem. While most people buy and sell them through exchanges, it's also possible though in some cases, like Bitcoin today, very time consuming to 'mine' these tokens by using your computer to solve complex mathematical equations. Here's how it works, and how you can mine your tokens.
