Bitcoin mining vmware esxi

Sometime back, one of my friends told me about Cryptocurrency mining using the Graphics Cards and since then I wanted to give it a try. Power consumption is one of the most important factors that affect your profitability with cryptocurrency mining. To keep things simple, I decided to use Windows 10 as the operating system on this machine. Though you can use any cryptocurrency mining application, I decided to use NiceHash to keep things simple.

McAfee Labs Sees Criminals “Infect and Collect” in Cryptocurrency Mining Surge


We looked into exploitation attempts we observed in the wild and the abuse of legitimate platforms Netlify and GitHub as repositories for malware. By: Nitesh Surana December 03, Read time: words. If this vulnerability is exploited, it allows attackers to map URLs to files outside the directories configured by Alias-like directives.

As the initial fix was deemed insufficient, a bypass was later reported for the fix and tracked as CVE However, when we looked at the malicious samples abusing this vulnerability, we found more of these exploits being abused to target different gaps in products and packages for malicious mining of Monero. In this blog, we look into the abuse of GitHub and Netlify repositories and platforms for hosting cryptocurrency-mining tools and scripts. We have already informed GitHub and Netlify of the malicious activities and they have taken down the accounts.

We observed attackers targeting the following package and products via security vulnerabilities disclosed in and for malicious cryptocurrency-mining activities through samples caught in our honeypots:.

We found it interesting that all the products and the particular package have had widely distributed public proofs of concept for pre-auth RCE. Looking at the Monero wallet from one such mining pool, we saw that the operation is still ongoing and actively accumulating Monero as of this writing.

The miner samples we found work on and abuse both Windows and Linux platforms. While the exploits used differ according to the infrastructure targeted, the batch scripts we identified works on both.

We saw the usage of Netlify and GitHub as the malware file servers for downloading batch scripts from an attacker-controlled account. The batch script is renamed as a temporary file and deleted after it starts running in the background.

The scripts c3. Afterward, the length of the Monero wallet address is calculated. If the length is not or 95 characters, the script exits. The wmic utility is used to further enumerate specific parameters in the system, such as the number of processors, maximum clock speed, L2 and L3 cache sizes, and CPU sockets.

These values are later used to calculate the Monero mining rate of the Windows host. For different mining rates, different ports are used on the mining pool. The zipped miner c3. If the unzip attempt fails, 7z is downloaded to extract the zipped file, and both the downloaded files 7za. The script also goes on to install the latest version of XMRig for Windows from the official repository.

Once the miner is successfully installed, the config files are modified using PowerShell. If the miner is already running c3. If not, persistence is added by modifying the Startup directory with the batch scripts to execute c3pool XMR miner with the configuration file. NSSM is a service helper program that helps install applications as services, and with it a user can specify logging to user-defined files.

Targeting Linux hosts The shell script starts with an infinite loop to remove all competing cryptominers found in the infected system, such as kinsing, kdevtmpfsi, pty86, and. If the variable is empty, then the process is killed and three directories are created, namely:. Executable permissions are assigned for the downloaded binary and the binary is executed via nohup.

Based on the frequency of attempts on the targeted products and the particular package in the past month, we believe there are more servers that remain unpatched and exposed to these exploits. More importantly, malicious actors will continue targeting these products and package for intrusion based on the availability of the proofs of concept, as well as the higher likelihood that these servers have yet to be patched.

Moreover, due to the wide usage of Linux and Windows platforms and the fact that all the miners identified here work on both, illicit cryptocurrency mining makes for a lucrative business with regard to the high volume of systems that can be targeted.

Moreover, IP reputation services will not flag these platforms as malicious because they are legitimate sources of programs and organizations.

These two factors in CDNs will likely prompt a development in the behavior of malicious actors who abuse these platforms for infection, even for routines and attacks unrelated to cryptocurrency mining. From another perspective, the malicious actors targeting these devices can appear almost unsophisticated considering the use of public proofs for attacks. The actors also operate on a regular basis and target as many machines as they can, given that they continue operating and getting cryptocurrency in their respective wallets despite the suspension of their GitHub and Netlify accounts.

Anti-Coinminer Mining Campaign

McAfee Labs saw on average five new threat samples every second, including growth in cryptojacking and other cryptocurrency mining malware, and notable campaigns demonstrating a deliberate drive to technically improve upon the most sophisticate established attacks of Criminals continued to adopt cryptocurrency mining to easily monetize their criminal activity. With the rise in value of cryptocurrencies, the market forces are driving criminals to crypto-jacking and the theft of cryptocurrency. Cybercrime is a business, and market forces will continue to shape where adversaries focus their efforts. The Lazarus cybercrime ring launched a highly sophisticated Bitcoin-stealing phishing campaign—HaoBao—which targeted global financial organisations and Bitcoin users. When recipients open malicious email attachments, an implant would scan for Bitcoin activity and establishes an implant for persistent data gathering and crypto mining.

Coinminer malware has been on the rise for some time. As more and more users become aware of this threat and try to take measures to protect themselves, cybercriminals are attempting to cash on that fear by serving crypto-miner malware from a website claiming to offer a coinminer blocker. Although the website looks unprofessional and would appear suspicious to most, there are plenty of non-tech savvy users who may fall for it. We have observed two variants of this malware strain being served from the above mentioned website as well as coin-blocker[. The purpose of final batch script is to download, setup and run monero miner on infected system.
