Frequently Asked Questions on Binance Pool ETH Mining
Metrics details. Illicit cryptocurrency mining has become one of the prevalent methods for monetization of computer security incidents. The most popular illicitly mined digital coin is Monero as it provides strong anonymity and is efficiently mined on CPUs. Illicit mining crucially relies on communication between compromised systems and remote mining pools using the de facto standard protocol Stratum.
While prior research primarily focused on endpoint-based detection of in-browser mining, in this paper, we address network-based detection of cryptomining malware in general. We propose XMR-Ray, a machine learning detector using novel features based on reconstructing the Stratum protocol from raw NetFlow records.
Our detector is trained offline using only mining traffic and does not require privacy-sensitive normal network traffic, which facilitates its adoption and integration. In our experiments, XMR-Ray attained Our evaluation furthermore demonstrates that it reliably detects previously unseen mining pools, is robust against common obfuscation techniques such as encryption and proxies, and is applicable to mining in the browser or by compiled binaries.
Finally, by deploying our detector in a large university network, we show its effectiveness in protecting real-world systems. Since then, the market has demonstrated its interest in this technology, and cryptocurrencies have proven to be a revolutionary asset class. However, the potential financial gains attracted not only investors but also malicious actors.
Security risks related to cryptocurrencies are diverse. Conventional hacking incidents at cryptocurrency exchanges e. Other prominent incidents included manipulation of wallet addresses [ 5 ], exploitation of wallet software [ 6 — 8 ], and compromise of mining power exchanges such as NICEHASH [ 9 ]. In contrast to such jackpot-style incidents, illicit mining of digital coins [ 10 ] is a far more reliable source of income for criminals.
Various sources have reported a dramatic rise in cryptocurrency mining malware in the last 2 years. Finally, large-scale attacks targeting enterprises are still widespread in e.
Our work is focused on detecting mining of Monero cryptocurrency abbr. XMR , the most prevalent one in the illicit cryptomining ecosystem due to its anonymity guarantees and the feasibility to use CPUs for mining [ 20 ]. Monero mining is typically performed by a group of miners clients connected to a common mining pool server which shares the workload and profit among miners. This arrangement boosts the chance for the entire pool to mine a new block and consequently obtain a reward for it, in turn maximizing the long-term expected gain for individual miners.
The de facto standard application layer protocol for communication between pool servers and clients is Stratum [ 21 ]. It has a minimalist syntax and uses simple logic for pool mining, which triggered our interest to investigate if it can be discriminated from other network traffic. Illicit cryptomining attacks can be categorized into two main families. Binary-based cryptomining malware is typically delivered via trojans which download and execute mining binaries as background processes.
In both cases, by abusing computational power of hundreds of hijacked devices, attackers can amass significant computational power and generate substabtial earnings. Crucially, it should be recognized as a breach indicator and promptly rectified to prevent further serious damage, e. Due to these security implications, illicit cryptomining has received growing attention in the research community, cf.
Section 3. The majority of previous work focused on understanding and assessing profitability of in-browser mining [ 24 — 27 ]; other work discussed its detection and mitigation [ 28 — 31 ]. Much less attention has been paid to binary-based cryptomining, comprising essentially the early investigation of Bitcoin mining botnets [ 32 ] and the comprehensive study of Monero mining malware [ 20 ].
In terms of detection techniques, the majority of prior work spotted mining on the endpoints by monitoring CPU or GPU usage and process metrics processor time, system calls, number of threads, etc. While endpoint-based approaches are appealing in their capability to identify salient features of cryptomining, their deployment is labor-intensive.
Network-based detection, in contrast, can be localized on critical network nodes, but existing approaches cannot cope with proxies and encryption. In this work, we demonstrate that essential properties of cryptomining activity can be accurately recovered from aggregated network traffic , i.
It inspects network traffic metadata, i. To alleviate the information loss in comparison to a full traffic dump, we introduce our principal innovation: a novel set of features based on constraint-solving which indicate whether a set of NetFlow records corresponding to a TCP session exhibits unique statistical regularities characteristic to Stratum.
Using our novel features, Stratum traffic can be discriminated from other traffic by deploying a one-class classifier trained solely on mining traffic obtained from legitimate mining pool clients.
As a result, we obtain a highly efficient, privacy-preserving detector resistant to encryption, tunneling and proxies, and outperforming detectors based on DPI. Its design and implementation are presented along with data collection in Section 5.
In Section 6 , we show that XMR-RAY , trained once on legitimate cleartext mining traffic in our lab, successfully generalizes to a variety of use cases. First, we evaluate it in a controlled environment with traffic collected from a large corporate network Section 5. Next, we assess its robustness against encryption as well as tunneling and apply it to both in-browser and binary-based mining traffic. We also show that it successfully detects traffic generated by mining malware.
Finally, we deploy it in a large university network and assess its false alarm rate. We design XMR-Ray , a machine learning system for detection of cryptocurrency mining. We propose a novel set of features for machine learning based on a form of constraint-solving which indicate whether NetFlow records corresponding to a TCP stream exhibit unique statistical regularities characteristic to Stratum.
We evaluate the detection performance of the proposed solution on a comprehensive collection of real-world traffic and compare it to the closest related prior work. We assess the false-positive rate of our system in a real-world deployment in a large university. Following the experimental evaluation, we discuss the main limitations of XMR-Ray in Section 7 and conclude the paper.
Mining is a fundamental operation for cryptocurrency networks. Every transaction added to a public ledger must be verified to avoid over- or double-spending. In the absence of a central authority, participants of the peer-to-peer network verify several transactions of their choice. Two mechanisms ensure that each participant verifies transactions honestly.
First, obtaining the right to permanently add a block to the ledger is made expensive. Second, honest work is adequately rewarded. Both mechanisms outlined above are implemented by mining which entails the contest for finding a padding to a block such that the hash function computed over the padded block evaluates to a value smaller than the given threshold.
Cryptographic hash functions are irreversible; hence, the only way to solve this problem is to brute-force the padding. The first participant to find a suitable padding announces the solution to the network and receives a small value in cryptocurrency as a reward. The threshold, and hence the problem difficulty, is adjusted such that a solution is expected once in a certain time interval. For miners without specialized computing resources, pooling together is the only realistic chance to gain any reward.
A mining pool server, connected to a cryptocurrency network, distributes tasks to pool participants clients.
When a client finds a solution, it reports it to the server, which in turn verifies it and broadcasts it to the cryptocurrency network. Once the solution is verified by the network, the server receives the reward, withholds a commission and distributes the rest among clients according to their work. A specialized application layer protocol called Stratum was developed for pooled mining.
Although there is no official standard for Stratum and its implementations may differ for different currencies, its workflow remains largely the same across implementations. Mining pools typically implement the following operations using Stratum:. Illegitimate or malicious mining refers to mining performed on hijacked resources. For example, employees may mine on a corporate computing cluster, or malware may use the CPU of an infected endpoint for monetization. There exist two prevalent techniques for malicious mining.
This type of mining is performed by malware delivered via spam, exploit kits, or trojans. Once a device is infected, it downloads and starts a mining binary executable. Previous studies reveal that cryptomining malware usually is a variant of a legitimate open-source mining client with custom configuration parameters, e. Monero abbrev. XMR is the preferred currency used by cryptomining malware, and XMRIG [ 33 ] is a popular legitimate mining tool deployed in most illicit mining campaigns [ 20 , 34 ].
Since , the number of coin miners has surged, with almost 4 million new samples in the third quarter of alone [ 13 ]. While the mining functionality has remained stable, its delivery methods and operational mechanisms have evolved with the malware ecosystem.
Another insidious attack vector targeted carrier-grade MikroTik routers vulnerable to remote login with authentication bypass [ 43 ]. Below, we present and categorize the most relevant work addressing the phenomenon of cryptojacking. For a comprehensive and detailed review of prior work, we refer the reader to [ 44 ]. In addition, we place this work in the broader context of threat detection and traffic classification. While detection initially focused on network packets [ 45 , 46 ], the rising link speeds made packet analysis infeasible and alternative approaches have emerged based on network aggregated flows, especially NetFlow [ 47 ].
Combined flow- and packet-based approaches were introduced for malware family classification [ 48 , 49 ]. Pure flow-based systems have been successful in detecting malware-related activities [ 50 — 52 ] like botnets [ 53 — 55 ], DoS attacks [ 56 — 58 ], scans [ 59 — 61 ], and worms [ 62 , 63 ]. Similarly, our work is based on NetFlow, but we introduce novel features specialized for mining detection. The problem addressed in our work may be seen as a special case of traffic classification, namely, identification of the Stratum protocol traffic.
Hence, our method is related to the respective work on traffic classification. Conti et al. Papadogiannaki et al. Traffic classification was also performed using first 5 packets of a TCP connection [ 67 ] or counting received packets and bytes [ 68 ].
The impact of traffic sampling on performance of detection systems was studied in [ 69 ]. We refer the interested reader to [ 70 , 71 ] for an exhaustive literature survey in traffic analysis and classification. A considerable body of related work investigated the cryptojacking ecosystem. In , Huang et al.

A pencil-and-paper round of SHA The mining process Bitcoin mining is a key part of the security of the Bitcoin system. The idea is that Bitcoin miners group a bunch of Bitcoin transactions into a block, then repeatedly perform a cryptographic operation called hashing zillions of times until someone finds a special extremely rare hash value. At this point, the block has been mined and becomes part of the Bitcoin block chain. The hashing task itself doesn't accomplish anything useful in itself, but because finding a successful block is so difficult, it ensures that no individual has the resources to take over the Bitcoin system. For more details on mining, see my Bitcoin mining article. A cryptographic hash function takes a block of input data and creates a smaller, unpredictable output. The hash function is designed so there's no "short cut" to get the desired output - you just have to keep hashing blocks until you find one by brute force that works. For Bitcoin, the hash function is a function called SHA In Bitcoin, a successful hash is one that starts with enough zeros.
Meanwhile, the crypto miner s who wanted to set up shop demanded the low electricity rates available to locals. From the development of the Weibo uncensored project to the detainment of a miner , signs appear to point to Beijing as the culprit. While cheap power has long been the primary consideration for crypto miner s, Colyer says that other factors are becoming increasingly important. Of Taylor Swift's many famous boyfriends: "She has seen more shafts than a coal miner.
Bitcoin Mining Made Easy
Bitcoin uses as much energy as the whole of Switzerland, a new online tool from the University of Cambridge shows. The tool makes it easier to see how the crypto-currency network's energy usage compares with other entities. However, one expert argued that it was the crypto-currency's carbon footprint that really mattered. Currently, the tool estimates that Bitcoin is using around seven gigawatts of electricity, equal to 0. That is as much power as would be generated by seven Dungeness nuclear power plants at once.

There's also live online events, interactive content, certification prep materials, and more. Mining is the process by which new bitcoin is added to the money supply. Mining also serves to secure the bitcoin system against fraudulent transactions or transactions spending the same amount of bitcoin more than once, known as a double-spend. Miners provide processing power to the bitcoin network in exchange for the opportunity to be rewarded bitcoin.

Subscriber Account active since. And they just so happen to be some of the best graphics cards for mining cryptocurrencies. Cryptomining is the process of solving complex problems to verify digital transactions using computer hardware — in this case, a graphics card. Miners can either create a cryptocurrency or get paid for their processing power in a cryptocurrency. Those graphics cards cost me a pretty penny, even if I bought them before the massive graphics-card price hikes caused by cryptominers buying them up.
Adrian Kingsley-Hughes is an internationally published technology author who has devoted over two decades to helping users get the most from technology -- whether that be by learning to program, building a PC from a pile of parts, or helping them get the most from their new MP3 player or digital camera. I'm old enough to remember being given a couple of bitcoins when they were worth next to nothing. Needless to say, I don't have them anymore. Now, with bitcoin and other cryptocurrency prices skyrocketing again, there's renewed interest in cryptomining, which is a way to accumulate cryptocurrency without having to pay for it.
