How The GPU Industry Is Priming For A Fattening Crypto Mining Market
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? The answer in most cases is — any code that earns the attackers a lot of money with little effort and as quickly as possible.
During a recent research project, we saw an extremely large spike of RCE attacks. A remote code execution vulnerability allows attackers to run arbitrary code on the vulnerable server.
For example, in a previous post we discussed RCE vulnerabilities related to insecure deserialization. In these types of vulnerabilities attackers can tamper with serialized objects that are sent to the web application.
Then, after the object is deserialized, malicious code will run in the vulnerable server. In our current research we focused on RCE attacks where the payload included an attempt to send a request to an external location. The method of sending such requests differs depending on the operating system and the desired result.
For example, attackers targeting Windows servers, used a Powershell command to download a file from an external location figure 1. Attackers targeting Linux servers, used Bash scripts, and wget or curl commands for the same purpose. Figure 1- Powershell command to download malicious script on a vulnerable Windows server. In the past, RCE payloads that sent requests to an external location included mostly attempts to infect servers with malware that added the vulnerable servers to a DDoS botnet.
This kind of attack is mostly profit based since the attackers can provide DDoS for hire services. In recent months, there has been a sharp increase in attempts to infect vulnerable servers with crypto-mining malware see figure 2. This kind of malware allows attackers to use the CPU or sometimes GPU power of the vulnerable server to mine crypto currencies. In this kind of attack, the attackers eliminate the need to sell their product to a third party and thus achieve a faster return on investment.
According to our research, in December almost 90 percent of all the malicious payloads in RCE attacks that sent a request to an external location were crypto-mining malware. Crypto mining uses computation power to solve difficult mathematical puzzles called proof of work functions. Each time such a problem is solved, the miner who solved it gets a fixed amount of coins, depending on which coin she or he was mining. For example, currently, bitcoin miners get But solving this puzzle alone is not an easy task, and a lot of computing power is needed.
Hence, miners use mining pools to increase their chances of getting paid. Mining pools are platforms that allow miners to work together and share computation resources to solve the puzzle. Once it is solved, the coins are divided between the participants of the pool according to how much computation power they each contributed.
To own and exchange crypto currency you need a crypto wallet. They store cryptographic keys which allow the user access to their currencies. Each wallet has an address which can be used to sign the wallet into a mining pool and send the profit of the mining process to the wallet. Another important aspect of crypto mining is the required hardware. Bitcoin is likely the most popular crypto currency and mining it is practically impossible using only regular CPU.
To mine Bitcoin a specific hardware is required or requires the use of GPU which allows more parallelization of the computation, thus improving the mining process. Other crypto currencies, like Monero, are newer and can be mined using regular CPU. In recent attacks we have seen a lot of malware using it to mine Monero. Bitcoin is the arguably the most popular crypto currency that exists, but still we have not seen a single attack trying to infect servers with Bitcoin mining malware.
Besides the fact that special hardware is required to mine Bitcoin while regular CPU can be used to mine the crypto currencies mentioned above, there is another notable reason. Bitcoin transactions are not private and coins can be traced back along the transaction chain. All the cryptocurrencies that we saw attackers trying to mine are more anonymous. This makes these anonymous crypto currencies a favorite for hackers to mine illegally on vulnerable servers.
Monero is also used as a way to launder money made illegally. For example there were reports that Bitcoins earned by the WannaCry ransomware were moved to Monero, probably as a means of hiding the source of the money. Next, we will follow an attack found in the wild, and through it try to understand the way that a crypto-mining malware works. The following attack figure 3 was found in the post body of an HTTP request that was trying to exploit an RCE vulnerability to send a wget command to download and run a script.
Figure 3- Code injected in a parameter trying to download and run a crypto-mining script. First, it kills processes that are running in the background of the server figure 4. These processes include mostly competing crypto miners, but also security controls and processes that use a lot of CPU. The way this script identifies competing crypto miners is either by killing the processes with known crypto-mining software, or by killing processes that include specific IPs or parts of crypto wallets.
Figure 4- The script kills processes that are running in the background. Figure 5- Gaining persistence by adding a new cron job. Figure 6- Downloading and running the crypto-mining malware. Figure 7- Dynamic configuration file containing the mining pool and the crypto wallet of the attacker.
In the downloaded configuration files we found, there were active Monero wallets that belonged to the attackers. By tracing the wallets and the mining pools, we saw the amount of money made using crypto mining.
Figure The wallet was suspended from the pool due to botnet activity. Most of the RCE payloads in our data contained crypto miners for Monero. But there were some attacks in which the payload was a crypto miner for other currencies.
One such currency is Electroneum, a relatively new crypto currency published in September This is a UK-based crypto currency designed specifically for mobile users. Figure 11 shows one of the Electroneum mining pools found in the payload which attackers tried to run. Figure Electroneum mining pool stats. Figure Electroneum balance of an attacker. Figure Karbowanec wallet found in one of the attacks. Last December almost 90 percent of all the RCE attacks that sent a request to an external source included a crypto-mining malware.
Attackers can make a lot of money off your server resources with crypto mining and there are many different crypto currencies to mine. The anonymity of transactions and the easy use of regular CPU make this attack very popular among hackers who want to earn money, and fast.
A crypto-mining malware causes denial of service to the infected server. With most of the server computation power directed to crypto mining, the server is rendered unavailable. Also, getting rid of the malware is not so easy due to its persistence as it adds a scheduled task to download and run it again after a certain period of time. To protect web applications from crypto-mining malware, the initial attack must be blocked.
Organizations using affected servers are advised to use the latest vendor patch to mitigate these kind of vulnerabilities. An alternative to manual patching is virtual patching. Virtual patching actively protects web applications from attacks, reducing the window of exposure and decreasing the cost of emergency patches and fix cycles.

Bitcoin Mining: How long does it take to mine 1 bitcoin?
The profitability of mining in has been significantly reduced but mining continues to be a source of small income. The most popular cryptocurrencies are currently mined with video card rigs and ASICs. However, there is another kind of mining, which is available to almost every owner of computing equipment — mining on a CPU. This article will help you figure out how to start mining on your processor and how profitable it is. Mining on a CPU is the process of mining cryptocurrency by finding a hash using the power of a central processor CPU and assigning it to a block inside the cryptocurrency blockchain. Initially, mining was launched on a central processor by the creator of Bitcoin — Satoshi Nakamoto. Back in the day, Satoshi managed to mine 1 mln.
Bitcoin network power slumps as Kazakhstan crackdown hits crypto miners
YouTube was recently caught displaying ads that covertly leach off visitors' CPUs and electricity to generate digital currency on behalf of anonymous attackers, it was widely reported. Word of the abusive ads started no later than Tuesday, as people took to social media sites to complain their antivirus programs were detecting cryptocurrency mining code when they visited YouTube. The warnings came even when people changed the browser they were using, and the warnings seemed to be limited to times when users were on YouTube. Great now my browser everytime I watch youtube Idk much about it but this is getting annoying and I need a solution please T n T. Por lo visto YouTube es muy gracioso y no le bastaba con bajarnos la audiencia, ahora van y nos meten el JavaScript de Coinhive para utilizar nuestros dispositivos para minar Monero! De verdad, Google! On Friday, researchers with antivirus provider Trend Micro said the ads helped drive a more than three-fold spike in Web miner detections. They said the attackers behind the ads were abusing Google's DoubleClick ad platform to display them to YouTube visitors in select countries, including Japan, France, Taiwan, Italy, and Spain. The ads contain JavaScript that mines the digital coin known as Monero.

How to Mine Monero
Raptoreum was designed as an anti-ASIC currency, as they wanted to keep the more expensive hardware solutions off their blockchain since they believed it lowered profits for everyone. To accomplish this they chose the Ghostrider mining algorithm, which is a combination of Cryptonite and x16r algorithms, and thew in some unique code to make it heavily randomized, thus its preference for L3 cache. The really affordable models, such as the X, have just 32MB of L3 cache, however. This means you could theoretically pay off the cost of the CPU in roughly six months, electricity costs aside. These L3 upgrades will certainly makes its chips even more desirable for Raptoreum miners, assuming the currency still exists when the updates arrive in early
After China’s Crypto Ban, Who Leads in Bitcoin Mining?
The Motley Fool. The constant droning sound is apparently driving them crazy. But what makes the process of bitcoin mining so noisy? To the uninitiated, bitcoin mining is the process of solving extremely complex computational math problems hashing puzzles using complex computer hardware. The goal for the computer is to find a solution to the problem and when one computer finds the solution, it is awarded a block of bitcoins and the process continues. As revealed by Investopedia , cryptocurrency mining is painstaking, costly and is rarely rewarding. Representational Image: Reuters.
