New Research: Crypto-mining Drives Almost 90% of All Remote Code Execution Attacks
According to IBM Managed Security Services MSS data, there have been peaks reaching more than a sixfold increase in attacks involving embedded mining tools in the eight-month period between January and August This is not surprising, since a recent third-party report noted that detections for cryptocurrency mining Trojans has risen significantly in the last few years. All of the attacks analyzed by IBM X-Force during that period involved the same mining tool with the capability to mine several different coins.
These tools were hidden within fake image files, a technique known as steganography, hosted on compromised web servers running Joomla or WordPress, or stored on compromised JBoss Application Servers.
Since MSS data only showed the results of the attack in the form of a request for a known malicious file, our researchers noted at least two possible scenarios:. A review of industries targeted revealed that manufacturing and financial services, both at 29 percent, tied for the industry experiencing the highest volume of these types of attacks.
Other industries that have been targeted include arts and entertainment, information and communication technology, and retail. The reason why certain industries were targeted over others is not easily explained. Although we have not identified any specific tools being used to scan for weaknesses in these platforms, we understand that it is a prerequisite in the exploitation of this attack type.
Attackers are likely targeting industries with the most vulnerable targets versus those that offer some type of advantage in terms of mining virtual currency. JexBoss is a tool for testing and exploiting Java deserialization vulnerabilities in JBoss application servers.
If JexBoss is resident on the target machine, it would indicate that the server is compromised and will allow shell commands to be executed. Upon further examination, the image file contains shell code and is not really an image file at all. The shell code instructs the victim host to download:. When we executed this mining tool in our lab, it connected to the aforementioned site and began mining Monero using the CryptoNight algorithm, which is the one used by the CryptoNote-based group of currencies:.
To do the testing, our research lab set up an x86 machine with an Intel i 4 core processor running an Ubuntu server. At a hash rate of Since organic infections would have every infected machine run its own rate of mining, it is difficult to speculate the profit of a botnet of, say, 10, hosts.
Our findings did show the potential for Monero to be slightly more profitable than mining for the more popular bitcoin BTC , for example, making it perhaps more attractive to attackers. This may be the reason for the jump in volume of attacks utilizing this type of mining tool. This allows them to do large amounts of bulky mathematical labor in a greater quantity than CPUs. Since they are the more powerful math problem solvers and alternative virtual currency is becoming much more popular among miners, there has been an extremely large demand for high-end GPU cards recently.
This has even resulted in a global shortage of high-end GPUs, especially of those focused on mining. They realize there is a large number of potential targets that are not utilizing GPUs. Most mainstream computers use integrated graphics processors IGP , which consume less power and are much cheaper. However, they are much slower than GPUs. IGPs are built into the computer motherboard, whereas GPUs are optional add-on hardware that have much higher power requirements.
The playing field is larger and there are more endpoints to enslave. Smart mining is currently available for all flavors of mining tools across all operating systems.
At first glance, Internet of Things IoT devices appear to be prime targets for mining because a vast majority of them are deployed with default settings, making them easy picking for compromise. However, their minimal computing power makes them less than ideal for mining bitcoin, even with a 1 million-device botnet.
Server-based targets have a wider range of power — certainly much more than the plethora of IoT devices that typically come with very little computing power. Although this analysis focused specifically on a Linux variant, keep in mind that there are plenty of other flavors of mining tools for Windows, Android and Apple products such as home routers and other connected devices. Virtually any attack vector that involves injecting executable code could turn a targeted system into a virtual coin miner for the attacker.
The most common methods of attack include:. One of the most successful methods of infiltration that we see is the failure to validate input fields on web applications.
To shut down the virtual mint trying to form on the infrastructure you protect, applying standard security precautions is the top priority. Security professionals should take the following steps:. Creating a one-stop shopping solution for preventing miners from being executed in your environment is almost impossible because so many variables exist.
Focus on your network specifics and take every precaution to identify and lock down the applicable entry points of malware and miners alike.

How to protect your computer from malicious cryptomining
Bill Buchanan does not work for, consult, own shares in or receive funding from any company or organisation that would benefit from this article, and has disclosed no relevant affiliations beyond their academic appointment. Nothing comes for free, especially online. Now some sites have found a new way to make money from you: using your computer to generate virtual currencies. Users may object to this, especially if it slows down their computers. But given how hard it is for most companies to make money from online advertising, it might be something we have to get used to — unless we want to start paying more for things. In the case of bitcoin, mining requires specialised hardware and consumes masses of energy. For example, each bitcoin transaction takes enough energy to boil around 36, kettles filled with water. In a year, the whole bitcoin mining network consumes more energy than Ireland. But bitcoin is not the only show in town and there are many competing cryptocurrences.

Showtime websites secretly mined user CPU for cryptocurrency
Some websites may use your computer to mine cryptocurrencies like Bitcoin and Monero. Here's how to stop them. Mining cryptocurrencies is a great way to earn small amounts of residual income that could possibly be worth much more in the future. This is becoming an alternative revenue source some websites and people with more nefarious intentions are banking on. This can come in the form of malicious software that is installed on a user's computer, an undetected JavaScript file that mines in the background or a pop-under window that can continue to mine coins even after the browser is closed. If you're not sure how to determine if your computer is being used to mine coins without your knowledge, make sure to read our article on detecting coin mining.

How to get BitCoin? BitCoin may be the most popular digital currency but it is getting harder and harder to mine. Because the entry barrier gets higher and higher as the pool of BitCoin available for mining shrinks. For those still interested in Digital Currency, also known as Cryptocurrency [ Wikipedia ] , here are 10 alternative digital coins. They are easier to mine, however, the down side is these companies might cease to exist if their popularity wanes. Which is the biggest alternative digital currency?

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. The more bitcoin that is mined, the harder the algorithms that must be solved to get a bitcoin become.
Bitcoin mining is now using more electricity than individual countries, more than Ireland or Nigeria, according to UK based energy website, Power Compare. Is renewable energy the solution? Find out.
