New Cryptominer Spotted, Attacks Using Windows and Linux Bots
Rocke has primarily been associated with cryptocurrency mining payloads and the Xbash malware family. However, in recent campaigns, notably those examined by Talos Group and Unit 42 in August and January respectively, the adversary has combined its cryptocurrency mining payloads with a script to establish persistence and uninstall security software that may prevent it from executing.
Depending on the configuration of web applications in your organization, legitimate command shells may appear very similarly to web shells and RCE vulnerabilities when examined via endpoint detection and response EDR telemetry. Since Rocke exploits a diverse array of services, it may be more effective to approach detection from a reporting perspective rather than an alerting perspective.
By leveraging this method, you can review endpoint data periodically to see which processes have spawned from PHP, Java, or other processes associated with the services that Rocke is thought to exploit. Downloading and Deobfuscating Code T When Rocke achieves code execution on an endpoint, the actor proceeds to use the curl or wget utilities to download payloads to execute with a bash shell.
The downloaded payloads are hosted using Pastebin, a popular online code repository. The above command is a first stage script that delivers further payloads to a host.
It uses the curl or wget command—depending on which is present on the host—then uses the base64 utility to deobfuscate the downloaded code and execute that result using the bash command shell. The first part of the second stage script delivered by Rocke attempts to stop other cryptocurrency miner processes with commands such as:.
These commands eliminate potential competition for resources on an infected system, but they also present a potentially high-fidelity alert for defenders. Most environments do not commonly execute these pkill commands with command line options including miner names.
After these process stopping commands, Rocke conducts additional reconnaissance to determine if unknown miners are executing on the system using the netstat command. By stringing the output of netstat together with text searches, the actor searches for additional processes to stop:.
These grep commands—along with the pkill commands above—present an interesting phenomenon: they are common fixtures among cryptocurrency miner script payloads for Linux in general that are not exclusive to Rocke.
For research on your own, you can perform a quick Google search to verify this using the following terms:. While traditional command line logging is rarely implemented on most Linux systems, EDR solutions or other audit technologies that keep this information allow a focused detection approach, even into historical records. Miner Payload Execution and Masquerading T As with previous payload deliveries, the miner itself is downloaded using curl or wget. First, a config. Execution in this manner is a form of masquerading, as the binary is named partially after a Linux kernel worker thread.
This becomes a high fidelity behavior to use for alerts. Rocke uses cron jobs to persist on victim systems. It gives system administrators the ability to execute commands on a schedule without the need to be logged in to a system. It also allows them the ability to schedule commands to execute as non-administrator users on a system. When adversaries manipulate cron jobs, they usually do so in one of two ways:.
In this case, Rocke uses both options. They placed malicious scripts into folders known to execute during cron jobs. This is achieved by using curl or wget , depending on system support, to download a bash shell script and write it into numerous folders:. Depending on the configuration of a Linux system, crontab schedules may exist in numerous locations for multiple users.
Rocke takes advantage of this to modify crontabs in these locations:. To modify these schedules, Rocke directly modifies the files by echoing content into them as shown above.
The echo method is harder to observe using EDR data as echo is an internal shell command rather than a utility. Hiding Processes with Process Injection T Rocke uses a novel method to hide the execution of kworkerds from casual observation. The adversary uses a modified version of the libprocesshider project compiled as a shared object, the Linux equivalent of a Windows Dynamic-Link Library DLL. This will prevent processes such as the ps utility from observing kworkerds , but it will not prevent security software that monitors syscalls from observing the malicious process.
Trend Micro showed the effects of this technique in a blog post. The ld. Changing Timestamps T To modify timestamps, numerous commands similar to this are issued:. The modification of timestamps with touch usually uses the current system time unless told otherwise.
This action blends the timestamps of numerous malicious files in with the timestamps of files changed during updates and installations. Adversaries deploying cryptocurrency miners on Windows commonly use built-in services to move laterally, and the same is true of Linux systems in this case.
Rocke looks for the presence of SSH public key configuration and a list of known local hosts on a Linux server to move laterally. If it successfully connects to any other system, the same sequence of events described in the rest of the article happens on connected systems. This behavior can lead to a medium confidence alert once some tuning brings system administration and software deployment noise down. For added realism, consider uploading the chain reaction to Pastebin for download and execution.
The tools and techniques used by Rocke to compromise Linux systems exhibit clear-cut, malicious behavior, and you can definitely use the behaviors to detect this actor in your environment. Approaching with the recommended steps will help you build detection capabilities for your Linux endpoints that will mirror coverage you have for the Windows portion of your network.

Stopping Competing Miners The first part of the second stage script delivered by Rocke attempts to stop other cryptocurrency miner processes with commands such as: pkill -f xmrig pkill -f Loopback pkill -f apaceha pkill -f cryptonight pkill -f stratum pkill -f minerd These commands eliminate potential competition for resources on an infected system, but they also present a potentially high-fidelity alert for defenders.
Discovering Competing Miners Using Network Connections T After these process stopping commands, Rocke conducts additional reconnaissance to determine if unknown miners are executing on the system using the netstat command. For research on your own, you can perform a quick Google search to verify this using the following terms: "pkill" "xmrig" site:pastebin. Miner Payload Execution and Masquerading T Once the path has been cleared of other miners, Rocke then deploys its mining payload.
Persisting with Cron Jobs T Rocke uses cron jobs to persist on victim systems. When adversaries manipulate cron jobs, they usually do so in one of two ways: Replacing the cron schedule, known as a crontab, with their own Placing a malicious script in a folder known to contain scripts that will execute hourly, daily, or weekly as part of existing cron jobs In this case, Rocke uses both options.
Defense Evasion Hiding Processes with Process Injection T Rocke uses a novel method to hide the execution of kworkerds from casual observation. Lateral Movement with SSH T Adversaries deploying cryptocurrency miners on Windows commonly use built-in services to move laterally, and the same is true of Linux systems in this case.

Mining Bitcoin and other cryptocurrencies can be a very profitable venture, provided you have the necessary hardware and software for the job. In fact, some of the software only works on operating systems designed specifically for them. Windows is a pretty good starting point thanks to its excellent support for all the latest hardware and the fact that most people are already familiar with it. Linux, on the other hand, is a much more versatile operating system that comes in a wide variety of distributions.
Home » Manuals » Which is better for mining linux or windows. Most of the miners when building farms use Windows 7 or 10 software for 32 or 64 bit. At the same time, many users note the lack of stability of Windows, susceptibility to viruses and hacker attacks, as well as regular problems with mining clients. As an alternative, experienced "miners" offer Linux mining, in particular, the assembly on Ubuntu is noted. Both operating systems under consideration are capable of efficiently calculating blocks of cryptocurrencies.
Mining is a very effective way of making extra profit, however, it requires some investments into the hardware to operate and start profit generation. Building and optimizing these systems are totally different concepts though and have numerous dependencies that are connected to the personal preference of the user. First of all the operating system OS , which one will be running the miner on is a huge decision. It is interesting to see the differences between the performance in OSs in comparison to each other. Secondly, it is also important to use what one is most comfortable with.
Bitcoins have gained an enormous reputation because of multiple factors: ease of trade and highly increasing values over the years. Serving as an alternative to the currencies circulated and authorized by the governments worldwide, Bitcoins saw the light of the day in , and little did everyone know about their stellar journey — by becoming one of the most coveted tokens of wealth. It is worth noting that Bitcoins are not created.
