Bitcoin mining malware
Introduction Cybercriminals are utilizing ransomware-like strategies from different target devices to covertly mine cryptocurrencies. Cryptocurrency mining became a lucrative business as cryptocurrencies grew in acceptance as well as value. In spite of the underlying doubt over the digital coins and blockchain technology required, the world gradually became warm to decentralized monetary forms. With time, cryptocurrencies have pulled in an inexorably enormous number of worldwide clients.

Here’s the truth about the crypto miner that comes with Norton Antivirus
Either way, the cryptomining code then works in the background as unsuspecting victims use their computers normally. The only sign they might notice is slower performance or lags in execution. One is to trick victims into loading cryptomining code onto their computers. This is done through phishing-like tactics: Victims receive a legitimate-looking email that encourages them to click on a link. The link runs code that places the cryptomining script on the computer.
The script then runs in the background as the victim works. The other method is to inject a script on a website or an ad that is delivered to multiple websites. Once victims visit the website or the infected ad pops up in their browsers, the script automatically executes. Hackers often will use both methods to maximize their return.
Some cryptomining scripts have worming capabilities that allow them to infect other devices and servers on a network. It also makes them harder to find and remove; maintaining persistence on a network is in the cryptojacker's best financial interest. To increase their ability to spread across a network, cryptomining code might include multiple versions to account for different architectures on the network.
The scripts might also check to see if the device is already infected by competing cryptomining malware. If another cryptominer is detected, the script disables it. They do steal CPU processing resources.
For individual users, slower computer performance might be just an annoyance. Organization with many cryptojacked systems can incur real costs in terms of help desk and IT time spent tracking down performance issues and replacing components or systems in the hope of solving the problem. Browser-based cryptojacking grew fast at first, but seems to be tapering off, likely because of cryptocurrency volatility and the closing of Coinhive, the most popular JavaScript miner that was also used for legitimate cryptomining activity, in March The decline began earlier, however.
The report suggests that cybercriminals have shifted more to ransomware, which is seen as more profitable. In January , researchers discovered the Smominru cryptomining botnet, which infected more than a half-million machines, mostly in Russia, India, and Taiwan. The simple reason why cryptojacking is becoming more popular with hackers is more money for less risk. WIth ransomware, a hacker might get three people to pay for every computers infected, he explains.
With cryptojacking, all of those infected machines work for the hacker to mine cryptocurrency. The risk of being caught and identified is also much less than with ransomware. The cryptomining code runs surreptitiously and can go undetected for a long time. Hackers tend to prefer anonymous cryptocurrencies like Monero and Zcash over the more popular Bitcoin because it is harder to track the illegal activity back to them. Most are not new; cryptomining delivery methods are often derived from those used for other types of malware such as ransomware or adware.
The Prometei, which as been around as early as , is a modular and multi-stage botnet designed to mine the Monero cryptocurrency. It uses a variety of means to infect devices and spread across networks. In early , however, Cybereason discovered that Prometei was exploiting Microsoft Exchange vulnerabilities used in the Hafnium attacks to deploy malware and harvest credentials.
The botnet would then use the infected devices to mine Monero. It first uses spear phishing to gain a foothold on a system, and it then steals Windows credentials and leverages Windows Management Instrumentation and the EternalBlue exploit to spread.
It then tries to disable antivirus software and competing cryptominers. In October, Palo Alto Networks released a report describing a cryptojacking botnet with self-spreading capabilities. Graboid, as they named it, is the first known cryptomining worm. It spreads by finding Docker Engine deployments that are exposed to the internet without authentication. Palo Alto Networks estimated that Graboid had infected more than 2, Docker deployments. In June , Palo Alto Networks identified a cryptojacking scheme that used Docker images on the Docker Hub network to deliver cryptomining software to victims' systems.
Placing the cryptomining code within a Docker image helps avoid detection. It can detect mouse movement and suspend mining activities. This avoids tipping off the victim, who might otherwise notice a drop in performance. A few months ago, Comodo Cybersecurity found malware on a client's system that used legitimate Windows processes to mine cryptocurrency. Dubbed BadShell it used:. At the EmTech Digital conference earlier this year, Darktrace told the story of a client , a European bank, that was experiencing some unusual traffic patterns on its servers.
A physical inspection of the data center revealed that a rogue staffer had set up a cryptomining system under the floorboards. In March, Avast Software reported that cryptojackers were using GitHub as a host for cryptomining malware. They find legitimate projects from which they create a forked project. The malware is then hidden in the directory structure of that forked project. Using a phishing scheme, the cryptojackers lure people to download that malware through, for example, a warning to update their Flash player or the promise of an adult content gaming site.
Cryptojackers have discovered an rTorrent misconfiguration vulnerability that leaves some rTorrent clients accessible without authentication for XML-RPC communication. They scan the internet for exposed clients and then deploy a Monero cryptominer on them.
F5 Networks reported this vulnerability in February, and advises rTorrent users to make sure their clients do not accept outside connections. Initially Facexworm delivered adware. Earlier this year, Trend Micro found a variety of Facexworm that targeted cryptocurrency exchanges and was capabile of delivering cryptomining code. It still uses infected Facebook accounts to deliver malicious links, but can also steal web accounts and credentials, which allows it to inject cryptojacking code into those web pages.
In May, Total Security identified a cryptominer that spread quickly and proved effective for cryptojackers. WinstarNssmMiner does this by first launching an svchost. Since the computer sees as a critical process, it crashes once the process is removed. Cryptojacking has become prevalent enough that hackers are designing their malware to find and kill already-running cryptominers on systems they infect.
CoinMiner is one example. It then kills those processes. Bad Packets reported in September last year that it had been monitoring over 80 cryptojacking campaigns that targeted MikroTik routers, providing evidence that hundreds of thousands of devices were compromised. The campaigns exploited a known vulnerability CVE for which MikroTik had provided a patch. Not all owners had applied it, however.
Since MikroTik produces carrier-grade routers, the cryptojacking perpetrators had broad access to systems that could be infected. He believes phishing will continue to be the primary method to deliver malware of all types. Here are the latest Insider stories. More Insider Sign Out. Sign In Register. Sign Out Sign In Register.

Cryptojacking scams are on the rise once again, after declining for two years
Cloud-native visibility, detection, and response for the hybrid enterprise. Find white papers, reports, datasheets, and more by exploring our full resource archive. Cryptomining malware, or 'cryptojacking,' is a malware attack that co-opts the target's computing resources in order to mine cryptocurrencies like bitcoin. This malware uses a systems CPU and sometimes GPU to perform complex mathematical calculations that result in long alphanumeric strings called hashes. These calculations serve to verify previous cryptocurrency transactions, and successfully solving them can generate a token of currency like bitcoin.
Is cryptocurrency mining malware the new ransomware?
A new report published by security researched Troy Mursch details how the cryptocurrency mining code known as Coinhive is creeping onto unsuspecting sites around the web. Mursch recently detected the Coinhive code running on nearly websites, including ones belonging to the San Diego Zoo, Lenovo and another for the National Labor Relations Board. The full list is available here. Most of the affected sites are hosted by Amazon and are located in the United States and Mursch believes that they were compromised through an outdated version of Drupal:. Soon thereafter, I was notified of additional compromised sites using a different payload. However, all the infected sites pointed to the same domain using the same Coinhive site key. Upon visiting the URL, the ugly truth was revealed. A slightly throttled implementation of Coinhive was found. Coinhive found on the website of the San Diego Zoo sandiegozoo in the latest high-profile case of cryptojacking.
New cryptojacking malware is targeting gamers through games like GTA V
Malware called "Crackonosh" has been found in , compromised computers that were used to download illegal, torrented versions of popular video games, including "NBA 2K19" and "Grand Theft Auto V," according to a report from security company Avast published Thursday. Monero is a privacy coin that is often used by cybercriminals because it is much more difficult to trace than other cryptocurrencies like bitcoin. The malware is thought to have originated in the Czech Republic, but it has a global reach. The leader in news and information on cryptocurrency, digital assets and the future of money, CoinDesk is a media outlet that strives for the highest journalistic standards and abides by a strict set of editorial policies.
Pirated copies of ‘Spider-Man: No way Home’ infected with crypto mining malware: Researchers
For a variety of different reasons, Bitcoin and other crypto-currencies has captured the imagination of economists, investors, engineers, and cyber-criminals. As security researchers, it captured our attention as a potential source for security threats. And such a threat eventually presented itself in the practice of crypto-mining. When a cyber gold-rush happens, the growth in the value of cryptocurrencies is astronomical. You can expect the involved parties to do anything within their power to yield as much profit before the rush is over although some would say this rush would never be over. This urge for quick profit is the main driver behind the development of malicious crypto-mining tools, which compromise devices with the intention of using them as free mining labor.
Crypto Mining: Definition and Function Explained
Category: Malware , Unit Tags: coin miner , coin mining , cryptojacking , exploit , PostgreSQL , vulnerabilities. Cryptojacking or simply malicious coin mining is a common way for malware authors to monetize their operations. While the underlying mining protocols and techniques remain fairly standard, malware actors tend to seek out and find smarter ways to hack into a victim's machines. Recently, Unit 42 researchers uncovered a novel Linux-based cryptocurrency mining botnet that exploits a disputed PostgreSQL remote code execution RCE vulnerability that compromises database servers for cryptojacking. We named the cryptocurrency mining botnet "PGMiner" after its delivery channel and mining behavior. At its core, PGMiner attempts to connect to the mining pool for Monero mining.
In December , 88 percent of all remote code execution RCE attacks sent a request to an external source to try to download a crypto-mining malware. These attacks try to exploit vulnerabilities in the web application source code, mainly remote code execution vulnerabilities, in order to download and run different crypto-mining malware on the infected server. RCE vulnerabilities are one of the most dangerous of its kind as attackers may execute malicious code in the vulnerable server. Have you ever wondered what kind of malicious code attackers want to execute?
Cryptojacking is a type of cybercrime that involves the unauthorized use of people's devices computers, smartphones, tablets, or even servers by cybercriminals to mine for cryptocurrency. Like many forms of cybercrime, the motive is profit, but unlike other threats, it is designed to stay completely hidden from the victim. Cryptojacking is a threat that embeds itself within a computer or mobile device and then uses its resources to mine cryptocurrency. Cryptocurrency is digital or virtual money, which takes the form of tokens or "coins.
We have been looking at the Crypto-Mining Malware Ecosystem for over a decade. This repository provides further details into our investigation, source code and data used present our findings at the Internet Measurement Conference IMC. Our analysis is live and we keep getting a better understanding of this ecosystem. We have an extended version of our IMC paper, although academic citations should look as follows for the time being:. All 2K campaigns are listed in here. Skip to content.
Mining requires a lot of computing power to solve complex calculations in order to create more bitcoins. To get the job done, miners usually create systems with many computers. But now, it seems that at least one miner has turned to malware to take advantage of unsuspecting users and add their mobile devices into his or her mining system. The mining apps that were recently removed worked by tricking users into downloading them by advertising themselves as wallpaper apps.
