Npm bitcoin mining

Cryptocurrency mining for Bitcoin, Etherium and other blockchain based currencies has been a tricky, confusing and sometimes controversial field for a while now. At work. In a high-security underground bunker. Crypto mining operations these days are thought of as huge sheds of whining GPU-festooned rigs, hammering away at whatever digital rockface they get bitcoin from, while a man in dark glasses and a hoodie furtively taps commands into a laptop and sips his Code Red Mountain Dew. While there is absolutely a grain of truth to this conception, the reality is significantly less compatible with a Vice special documentary or an edgy Amazon Original Drama.

The lib in question, event-stream , is downloaded roughly two million times a week by application programmers. This vandalism is a stark reminder of the dangers of relying on deep and complex webs of dependencies in software: unless precautions are taken throughout the whole chain, any one component can be modified to break an app's security.

If your project uses event-stream in some way, you should check to make sure you didn't fetch and install the dodgy version during testing or deployment. Here's how it all started: a developer identified on GitHub as "right9control" volunteered to take over event-stream , which had been built by another dev.

The JavaScript was then briefly updated to include another module, flatmap-stream , which was later modified to include Bitcoin-siphoning malware — prompting alarm yet again that those pulling third-party packages into their apps have no idea what that code may be doing. A timeline can be found here , but in short: on September 9, right9control added flatmap-stream as a dependency to event-stream , and then on September 16, removed the dependency by implementing the code themselves.

However, this latter change was not automatically pushed out to the library's users. On October 5, flatmap-stream was altered by a user called "hugeglass" to include obfuscated code that attempted to drain Bitcoins from wallets using the software.

Thus, anyone using event-stream and pulling in the cursed flatmap-stream , rather than the rewritten code, since October 5 would be potentially hit by the malicious script. The offending code has been removed from event-stream. If it's any relief, the hidden malware is highly targeted, and not designed to attack every programmer or application using event-stream. According to Sparling, a commit to the event-stream module added flatmap-stream as a dependency, which then included injection code targeting another package, ps-tree.

The malicious code in flatmap-stream 0. EventStream was created by Dominic Tarr, a New Zealand-based developer who stopped maintaining the code.

According to Tarr, right9control emailed him to say that he wanted to take over maintenance of the project, and was granted access because Tarr no longer had any interest in looking after it. The Register emailed right9control, based in Tokyo if the individual's GitHub profile is accurate, but we've received no response.

A server used for the attack is run by a service provider operating out of Kuala Lumpur, Malaysia. It may well be that right9control had no idea flatmap-stream would be tampered with to smuggle in wallet-raiding code when updating event-stream to use the module.

Some developers commenting via the GitHub issues post and elsewhere have criticized Tarr for failing to provide adequate notice to the code community about the change in event-stream 's ownership. Others argue that the software license specifically disclaims any responsibility and that developers have only themselves to blame for trusting code that comes with no guarantees. In a phone interview with The Register , NPM director of security Adam Baldwin said, "Based on our current analysis, which is not complete yet, the early indications suggest it's an extremely targeted attack on a Bitcoin platform.

Baldwin said NPM has not yet gathered data on the number of individuals who downloaded the compromised code for their Node. He confirmed that version 3. Despite the ongoing addition of defenses like automated vulnerability scanning and of reporting mechanisms, the risks are unlikely to go away while people have the freedom to publish unvetted code.

However, dependency pinning — in which a specific version rather than a range of versions is required — can help. Asked about how this situation might be avoided in the future, Baldwin acknowledged that both unmaintained code and transferring code ownership pose potential problems.

He credited the NPM community for identifying the malicious code and said if the organization tightened things down so much that no one could publish code, it would harm the community. It's existed for more than a year and the site's operators don't appear to be interested in fixing it. Scientists have confirmed the discovery of Earth's second Trojan asteroid leading the planet in its orbit around its nearest star.

Dubbed XL5, the hunk of space rock was discovered in December Although excitement surrounded the early observations of a second Earth Trojan, low observational coverage meant uncertainties in the data were too great for a scientific confirmation.

Trojan asteroids are small bodies sharing an orbit with a planet, which remain in a stable orbit approximately 60 degrees ahead of or behind the main body. On the last day of January, Oracle Linux 8. It's packaged to run on the Windows Subsystem for Linux and says it needs Windows 10 version That's the much-delayed Windows 10 May update, also known as 20H1.

This is the first official presence of any member of the greater Red Hat family — although Oracle Linux isn't directly a Red Hat product, obviously — in Microsoft's online souk. The concept is reckoned to have first been used in the mids, though it came to prominence around and has really started to take off in the past three years or so. But when we say "take off", we don't really mean it's become ubiquitous, or the default approach to security used by the majority of companies.

No, we really mean that lots of people have started to talk about it and seriously contemplate using it … but not necessarily to put those words and thoughts into action. Big numbers, and not all that far apart. Google Cloud has racked up another 12 months of losses, despite extending the life of its hardware by a year.

The search and ads giant in revealed that it extended the operational lifespan of its cloud servers from three to four years and found it could squeeze an extra couple of years out of some networking kit, sometimes going five years between refreshes.

A deal that would have brought a German silicon wafer manufacturer under Taiwanese control has been scuppered by German regulators — with help from China. GlobalWafer holds around a third of the global market and the deal would have made it the world's second-largest player. As is nearly always the case with foreign takeovers, the deal required signoff from German regulators, who moved … slowly. India's government has ordered its Reserve Bank to have a digital rupee into circulation by next year, and outlined plans to raise revenue with a 30 per cent income tax on cryptocurrency and non-fungible tokens.

The two plans were announced yesterday by finance minister Nirmala Sitharaman as she revealed the nation's budget for The crypto tax is the first item listed in a section of the budget memo headed "Revenue Mobilization". The document [PDF] explains that India wants to tax income from crypto-assets at a 30 per cent flat rate. The EARN IT Act, a legislative bill intended "to encourage the tech industry to take online child sexual exploitation seriously" has been revived in the US Senate after it died in committee back in And advocacy groups have once again decried the bill for threatening free speech and access to encryption, and for imperiling the liability protection that allows online service providers to host third-party content.

In other words, the bill's reception has been much the same as it was two years ago. The informant claimed senior NSO executives offered "bags of cash" to California-based telecoms security and monitoring outfit Mobileum to assist in its surveillance work, according to the Washington Post on Tuesday. Specifically, it's alleged NSO wanted to gain, with Mobileum's help, Signaling System 7 -level access to US cellular networks, a position that can be abused to determine a cellphone's location, redirect and read its incoming text messages, snoop on calls , and more.

SS7 is the glue between telecommunications providers, and subverting it opens up a wealth of opportunities for spies and miscreants. MariaDB Corporation Ab, which sells the popular open source database by the same name, said on Tuesday that it intends to become a public company with the help of Angel Pond Holdings Corporation.

It was formed by Shihuang "Simon" Xie, a co-founder of Alibaba Group, and Theodore Wang, a former Goldman Sachs partner, to raise capital from investors in order to acquire another company. SPAC-driven deals have become popular in recent years partly as a defense against market volatility, which can complicate initial public offerings when companies try to go the traditional route to market.

They also provide a clearer exit path for investors, allowing acquired firms to go public more quickly and at less cost, and to negotiate their value directly with the SPAC.

How to Run a Bitcoin Node

Hackers hijacked the popular UA-Parser-JS NPM library, with millions of downloads a week, to infect Linux and Windows devices with cryptominers and password-stealing trojans in a supply-chain attack. The library is immensely popular, with millions of downloads a week and over 24 million downloads this month so far. In addition, the library is used in over a thousand other projects, including those by Facebook, Microsoft, Amazon, Instagram, Google, Slack, Mozilla, Discord, Elastic, Intuit, Reddit, and many more well-known companies. According to the developer, his NPM account was hijacked and used to deploy the three malicious versions of the library. When the compromised packages are installed on a user's device, a preinstall. If the package is on a Linux device, a preinstall. If the device is not located in those countries, the script will download the jsextension [ VirusTotal ] program from [.

What is a Bitcoin Node? Mining versus Validation

Nodes on the blockchain communicate with each other about transactions and new blocks. A Node is a part of cryptocurrency that is needed to make most of the popular tokens like Bitcoin or Dogecoin function. It's a fundamental part of the blockchain network, which is the decentralised ledger that is used to maintain a cryptocurrency. The involvement of a greater number of people in the cryptocurrency market is pushing the desire in them to learn how the system works. This is true for any sector but the newness of cryptocurrency is also leading to curiosity.

Supply-chain attack on NPM Package UAParser, which has millions of daily downloads

To put it simply, Bitcoin mining is the process that is required to create new Bitcoin. To better understand how Bitcoin mining works, we will address the following key points:. Where do bitcoins come from? With other forms of currencies, a central authority decides how money is printed and distributed. Mining is how new bitcoins are added, and transactions are validated in the Bitcoin network. A blockchain is a continuously growing list of records, called blocks which are cryptographically linked and secured to form a chain of records.

A mining node is a node which contributes to the network by guessing the combinations needed to “seal” the blocks of transactions and thus.
