New Research: Crypto-mining Drives Almost 90% of All Remote Code Execution Attacks
The surge in Bitcoin prices has driven widescale interest in cryptocurrencies. While the future of digital currencies is uncertain, they are shaking up the cybersecurity landscape as they continue to influence the intent and nature of attacks. Cybercriminals gave cryptocurrencies a bad name when ransomware started instructing victims to pay ransom in the form of digital currencies, most notably Bitcoin, the first and most popular of these currencies.
It was not an unexpected move — digital currencies provide the anonymity that cybercriminals desire. The sharp increase in the value of digital currencies is a windfall for cybercriminals who have successfully extorted Bitcoins from ransomware victims.
These dynamics are driving cybercriminal activity related to cryptocurrencies and have led to an explosion of cryptocurrency miners also called cryptominers or coin miners in various forms. Mining is the process of running complex mathematical calculations necessary to maintain the blockchain ledger. This process rewards coins but requires significant computing resources.
Coin miners are not inherently malicious. Some individuals and organizations invest in hardware and electric power for legitimate coin mining operations.
However, others are looking for alternative sources of computing power; as a result, some coin miners find their way into corporate networks. While not malicious, these coin miners are not wanted in enterprise environments because they eat up precious computing resources. As expected, cybercriminals see an opportunity to make money and they customize coin miners for malicious intents.
In enterprise environments, Windows Defender ATP provides the next-gen security features, behavioral analysis, and cloud-powered machine learning to help protect against the increasing threats of coin miners: Trojanized miners, mining scripts hosted in websites, and even legitimate but unauthorized coin mining applications.
Cybercriminals repackage or modify existing miners and then use social engineering, dropper malware, or exploits to distribute and install the trojanized cryptocurrency miners on target computers. Every month from September to January , an average of , unique computers encountered coin mining malware. Interestingly, the proliferation of malicious cryptocurrency miners coincides with a decrease in the volume of ransomware. Are these two trends related?
Are cybercriminals shifting their focus to cryptocurrency miners as primary source of income? We have seen a wide range of malicious cryptocurrency miners, some of them incorporating more sophisticated mechanisms to infect targets, including the use of exploits or self-distributing malware.
We have also observed that established malware families long associated with certain modus operandi, such as banking trojans, have started to include coin mining routines in recent variants. These developments indicate widespread cybercriminal interest in coin mining, with various attackers and cybercriminal groups launching attacks. The downward trend in ransomware encounters may be due to an observed shift in the payload of one of its primary infection vectors: exploit kits. Even though there has been a continuous decrease in the volume of exploit kit activity since , these kits, which are available as a service in cybercriminal underground markets, are now also being used to distribute coin miners.
Before ransomware, exploit kits were known to deploy banking trojans. DDE exploits, which have also been known to distribute ransomware, are now delivering miners. A , which then downloads the trojanized miner: a modified version of the miner XMRig, which mines Monero cryptocurrency. Other miners use reliable social engineering tactics to infect machines. For cryptocurrency miners, persistence is a key element. The longer they stay memory-resident and undetected, the longer they can mine using stolen computer resources.
While more traditional persistence mechanisms like scheduled tasks and autostart registry entries are common, cybercriminals can also use more advanced methods like code injection and other fileless techniques, which can allow them to evade detection. It adds a scheduled task so that it runs every time the computer starts. Some coin miners have other capabilities.
A SHA 80fac43f17dbd0f7bb6badccefcbcdae7bcd drops a copy in the root folder of all available drives, including mapped network drives and removable drives, allowing it to spread as these drives are accessed using other computers. It then runs legitimate cryptocurrency miners but using its own parameters. As trojanized cryptocurrency miners continue evolving to become the monetization tool of choice for cybercriminals, we can expect the miners to incorporate more behaviors from established threat types.
Coin mining scripts hosted on websites introduced a new class of browser-based threats a few years ago. The increased interest in cryptocurrencies has intensified this trend. While some websites claim legitimacy by prompting the visitor to allow the coin mining script to run, others are more dubious. Some of these websites, usually video streaming sites, appear to have been set up by cybercriminals specifically for coin mining purposes.
Others have been compromised and injected with the offending scripts. One such coin miner is hidden in multiple layers of iframes.
Figure 2. A sample coin mining script hidden in multiple layers of iframes in compromised websites. We have also seen have seen tech support scam websites that double as coin miners.
Tech support scam websites employ techniques that can make it difficult to close the browser. Meanwhile, a coin mining script runs in the background and uses computer resources. On top of malware and malicious websites, enterprises face the threat of another form of cryptocurrency miners: legitimate but unauthorized miners that employees and other parties sneak in to take advantage of sizable processing power in enterprise environments.
Miners in corporate networks also result in additional energy consumption, leading to unnecessary costs. Unlike their trojanized counterparts, which arrive through known infection methods, non-malicious but unauthorized cryptocurrency miners might be trickier to detect and block.
In January , Windows enterprise customers who have enabled the potentially unwanted application PUA protection feature encountered coin miners in more than 1, enterprise machines, a huge jump from the months prior.
We expect this number to grow exponentially as we heighten our crackdown on these unwanted applications. Figure 4. Volume of unique computers in enterprise environments with PUA protection enabled that encountered unauthorized coin miners. In contrast, trojanized miners are classified as malware; as such, they are automatically detected and blocked by Microsoft security products.
Windows Defender AV blocks potentially unwanted applications when a user attempts to download or install the application and if the program file meets one of several conditions.
Potentially unwanted applications that are blocked appear in the quarantine list in the Windows Defender Security Center app. Windows 10 Enterprise customers benefit from Windows Defender Advanced Threat Protection, a wide and robust set of security features and capabilities that help prevent coin miners and other malware.
Windows Defender AV uses multiple layers of protection to detect new and emerging threats. Enterprises can also use Windows Defender Application Control to set code integrity policies that prevent employees from installing malicious and unauthorized applications. Trojanized cryptocurrency miners are blocked by the same machine learning technologies, behavior-based detection algorithms, generics, and heuristics that allow Window Defender AV to detect most malware at first sight and even stop malware outbreaks, such as the massive Dofoil coin miner campaign.
By leveraging Antimalware Scan Interface AMSI , which provides the capability to inspect script malware even with multiple layers of obfuscation, Windows Defender AV can also detect script-based coin miners. Coin mining malware with more sophisticated behaviors or arrival methods like DDE exploit and malicious scripts launched from email or Office apps can be mitigated using Windows Defender Exploit Guard , particularly its Attack surface reduction and Exploit protection features.
Malicious websites that host coin miners, such as tech support scam pages with mining scripts, can be blocked by Microsoft Edge using Windows Defender SmartScreen and Windows Defender AV. Corporate networks face the threat of both non-malicious and trojanized cryptocurrency miners.
Windows 10 S , a special configuration of Windows 10, can help prevent threats like coin miners and other malware by working exclusively with apps from the Microsoft Store and by using Microsoft Edge as the default browser, providing Microsoft-verified security. Security operations personnel can use the advanced behavioral and machine learning detection libraries in Windows Defender ATP to detect coin mining activity and other anomalies in the network.

Electricity needed to mine bitcoin is more than used by 'entire countries'
RX 4GB. IS NOT included. Current market price is 0. Increasing hashrate. General info performance memory ports features. Engine Clock - Up to MHz.
The Cost of Bitcoin Mining Has Never Really Increased
Bitcoin mining began as a cottage industry with individual miners able to mine Bitcoin on a laptop. Over the years, the technology became more specialized and sophisticated, with large facilities taking over the industry. But with the launch of its at-home mining program, Compass Mining is betting that individual bitcoiners will want to mine bitcoin once again. Bitcoin miners play a key role in securing the Bitcoin blockchain. They compete for the right to compile transactions in new blocks and add them to the chain. In return, successful miners are rewarded with newly minted bitcoin 6. But the cost of setting up and operating a bitcoin mining rig can certainly cut into your profits. And typically the price has been prohibitively high for the average at-home miner. Read more: How Bitcoin Mining Works. All rigs can still be plugged into a mining pool, meaning that any rewards found by your pool will be shared with you in proportion to the hashrate you contribute.
RIG exploit kit campaign gets deep into crypto craze
Bitcoin mining — the process in which a bitcoin is awarded to a computer that solves a complex series of algorithm — is a deeply energy intensive process. Bitcoin mining — the process in which a bitcoin is awarded to a computer that solves a complex series of algorithms — is a deeply energy-intensive process. Miners are rewarded in bitcoin. But the way bitcoin mining has been set up by its creator or creators — no one really knows for sure who created it is that there is a finite number of bitcoins that can be mined: 21m.
Bitcoin is eating Quebec
At a computer store in downtown San Francisco, a five-shelf cabinet normally filled with graphics cards — popular add-ons that soup up PCs — stands bare. People who help mine, or create, bitcoin and other cryptocurrencies are snapping up the processors as the currencies have soared in value. Whenever people buy and sell these digital coins, the transaction is verified through a series of complex mathematical computations. Whoever does that math earns some currency themselves. College students are using free dorm electricity to make a fortune.
Watts Miners Brings the Most Powerful Crypto Mining Rigs to Market
Bitcoin miners hit hard by the cryptocurrency's crash may be throwing in the towel. The bitcoin network's hash rate, one way of gauging the computing power dedicated to mining the digital currency, dropped about 24 percent from an all-time high at the end of August through this past Saturday, according to Blockchain. While the decline may have partially resulted from miners switching to other cryptocurrencies, JPMorgan Chase says some in the industry are losing money after bitcoin's price tumbled. Bitcoin miners, who perform the computations necessary to confirm transactions in the cryptocurrency, are rewarded for their efforts with bitcoins. If prices suffer a sustained drop below miners' breakeven costs determined by their electricity bills, mining-rig efficiency, and other factors , they may be forced to shut down to avoid operating at a loss. New York time on Monday. The Bloomberg Galaxy Crypto Index slipped to a month low.

How to build a crypto-mining rig. Read More. Coinbase, which makes money off the volume of people transacting on its platform to buy and sell currencies, had 6.
Usb miner ethereum
A few months ago, my son began to take an interest in cryptocurrency, and we decided to build an Ethereum mining rig together. At the risk of sounding immodest, my son James is a pretty quick study, and he has a strong technical aptitude like his father. When he first started to research cryptocurrency and make some small investments in Bitcoin, Litecoin and Ethereum, I was skeptical. But his enthusiasm was contagious, and I labored mightily to keep up as he educated me on blockchain technology, the cryptocurrency exchanges, wallets with public and private keys, and other foreign topics. As time went by and I learned more, I began to more fully understand the underpinnings of the blockchain, and how cryptocurrencies use this technology to implement distributed ledgers. As such, they are independent of any fiat money that a government has declared to be legal tender.
Bitcoin energy use - mined the gap
It is part of a blockchain-based initiative to help photographers control their image rights. Kodak also detailed plans to install rows of Bitcoin mining rigs at its headquarters in Rochester, New York. Kodak is the latest in a series of companies to see its value jump after revealing plans for blockchain-related activity. Kodak developed a digital camera in , but decided not to commercialise the technology at the time, and its hesitation to leave behind its film heritage is thought by some to have contributed to it filing for bankruptcy protection years later in Since that collapse, Kodak has licensed its brand to a variety of manufacturers, with the mark appearing on batteries, printers, drones, tablet computers and digital cameras. The KashMiner operation will be run by Spotlite, a licensee that had previously teamed up with Kodak to use its brand to market LED lights. More from CES:.
