Crypto miner trojan

Cyber criminals are targeting gamers with "mining malware" as they look to get crypto-rich, according to research published by security firm Avast. Once installed, Crackonosh quietly uses the computer's processing power to mine cryptocurrencies for the hackers. Avast researcher Daniel Benes told CNBC that infected users may notice that their computers slow down or deteriorate through overuse, while their electricity bill may also be higher than normal. Some , users have been infected worldwide and devices are being infected every day, according to Benes. However, Avast only detects malicious software on devices that have its antivirus software installed so the actual number could be significantly higher. Brazil, India and the Philippines are among the worst affected countries, while the U.

On the trail of the XMRig miner

What is Bitcoin? Bitcoin [1] is a kind of digital currency generated by the open source P2P software. It possesses the quality of not being able to be frozen or tailed, no tax payment and low transaction cost. It can also be redeemed at real cash value according to the current exchange rate as shown in figure 2. Consequently, a huge number of users are using bitcoins to do online shopping, support what they are interested in, play cards and so on.

However, some people believe that it is just these features of bitcoin that may be taken use of by misfeasors to gamble or sell drug. Everytime a user works out a chain, he can get appropriate bitcoins as a reward. With the rapid development of bitcoin, the corresponding malware emerges. Symantec also warned about the possibility of botnets pointing to bitcoin. A vast number of infected computers form a big computer cluster to work out a computing task. Whenever a task is solved, the virus author will get a certain amount of bitcoins as shown in figure 3.

Antiy labs has arrested two samples of this malware, the MD5 values of which are shown in table 1. It is found that the static file information of them is approximately equal as shown in figure 4 and their major functional codes are also similar.

They disguise as Google file and Realtek file respectively. The second sample spreads by being bounded with the decrypting program of Angry Birds.

We also found that there exists difference between the subordinate data of the two samples. After analyzing, it is found that these data are the configuration information of samples. The following information in red frame is the bitcoin address parameter. The one in green is the delay time with second as the unit of time after running the samples, closing the service and connecting to the internet.

Then it modifies the registry and sets UAC User Account Control of Windows7 as close in order to remove the security attention for its follow-up operations. It can be seen from here that the malware can infect Windows7 OS. The malware creates the file of reg.

The key value of this registry is used for auto startup after the computer starts. The malware contains word strings encrypted by base After being decrypted, they are found to be the names of system services as shown in table 3.

By connecting to the Internet, the author-arranged content can be obtained. The web content is also encrypted. The red part in figure 7 contains the ID of publisher, the date of establishment and the visit count.

The data can be used to help determine the developing time of malware and the number of infected computers. No valuable information is found about it by searching on Google. The malware decrypted the web content in local computer.

The decrypted content, as shown in figure 5, contains some Slovakian words, based on which we infer that the author may be a Slovakian. The malware matches the address and password according to its own subordinate data. If a computer is infected, the normal use of the computer will be seriously affected.

By calculation [4], it can be known that a computer with usual performance can obtain 0. If the infected count is one thousand, then bitcoins can be made in theory. If the infected count is a hundred thousand or even millions, it is conceivable that the malware author can obtain large amounts of bitcoins as shown in table 6.

It expends considerable hardware and electricity resources, severely affecting the normal use of a computer. While squeezing the computer resources, it creates wealth for the malware author. It can be taken as the turtledove that takes over the nest of a magpie in IT field. Antiy Labs is a vender of antivirus engine and solution, providing the best-in-breed antivirus engine and next generation antivirus services for confronting PC malware and mobile malware.

Cryptomining Malware: Definition, Examples, and Prevention

Security researchers at Slovak security firm ESET have discovered a new family of malware that they say has been using a variety of techniques to steal cryptocurrency from unsuspecting users since at least December KryptoCibule poses a three-pronged threat when it comes to cryptocurrency. In this way, KryptoCibule attempts to surreptitiously mine cryptocurrency on infected PCs without users detecting anything suspicious. Thirdly, the malware scouts drives attached to an infected computer, hunting for files which might contain content of interest — such as passwords and private keys. To disguise its behaviour, users who download the torrents and execute the installer do not realise that malicious code is being run in the background.

Newly-discovered KryptoCibule malware has been stealing and mining cryptocurrency since 2018

Norton is owned by Tempe, Ariz. In , the identity theft protection company LifeLock was acquired by Symantec Corp. Only you have access to the wallet. NortonLifeLock began offering the mining service in July , and early news coverage of the program did not immediately receive widespread attention. That changed on Jan.

Norton Botnet? In addition, if you choose to exchange crypto for another currency, you may be required to pay fees to an exchange facilitating the transaction.

Trojan.BitCoinMiner

While searching through our telemetry, we found a handful of logs where a database server process sqlservr. The downloader retrieved a cryptominer called MrbMiner. Based on open-source intelligence, the miner appears to have been created, hosted, and controlled by a small software development company based in Iran. When IT admins want to host a database, they have certain performance requirements: The ability to process lots of data reads and writes, and enough RAM and processor overhead to respond promptly to queries. People who live in countries that are under strict international financial sanctions, like Iran, can leverage cryptocurrency to bypass the traditional banking system.

Trojan.Win32.Miner

On 6th December , FortiGuard Labs discovered a compromised website - acenespargc[. Looking into the source code, we noticed a suspicious encrypted script which the uses eval function to convert all the characters into numbers. We used a tool called CharCode Translator to reverse the numbers back into characters. We were then able to retrieve a link which redirects to a scam page or phishing website. The above is just a simple example.

Cryptocurrency has arrived, and with it a new form of cybercrime: cryptojacking. What does cryptojacking mean for your online security? Find out everything you need to know about miner viruses, the potentially dangerous uses of Coinhive, and how to detect and remove Bitcoin mining malware from your devices. Cryptojacking is the act of hijacking a person's computer to secretly mine cryptocurrency. Because cryptojacking requires increasing processing power to mine cryptocurrencies like Bitcoin, miners are discovering new ways to wield that processing power. One such way is to borrow it from thousands of unwitting internet users. In fact, personal devices were doing more cryptocurrency mining than anything else that year. One result was the development of Bitcoin mining malware.

The Growing Trend of Coin Miner JavaScript Infection

In previous crypto-mining attacks, we observed hackers investing little to no effort in hiding their malicious activities. They just ran the malicious container with all of its scripts and configuration files in clear text. This made the analysis of their malicious intent fairly easy. One such cryptocurrency-mining attack was previously identified, with a malicious container image that was pulled from a public Docker Hub repository named zoolu2. It contained a number of images including Shodan and cryptocurrency-mining software binaries.
