AcruxMiner — Distribution Methods

The AcruxMiner is a malicious cryptocurrency miner that has been detected in an active distribution campaign. At the moment there is no information about the hacker or criminal collective responsible for its creation or distribution. It is possible that such data will be known in the future.

The first detection of it was made in May 2018 when its activity was discovered for the first time. Further analysis into its origins shows that it is promoted by its developers on various hacker underground markets. This means that prospective buyers can buy the bare threat and add new modules to it or order a complete and customized solution. It can be combined with other threats as well — ransomware, Trojans e etc.

As soon as the AcruxMiner malware is prepared it will be distributed using some of the popular tactics.

Usually most of these threats are built into the websites via JavaScript code. Once the users visit the respective sites their browsers will automatically run the code and as a result start the miner code. Other sources of infection include the following:

  • Mensagens de e-mail — The scripts that start the cryptocurrency miner can also be included in email messages. All interactive contents placed in the body message can lead to the execution of such code. The emails themselves impersonate well-known senders such as services and companies.
  • documentos — Macro-infected documents of all popular types can serve as infection sources: apresentações, bases de dados, documentos de texto ricos e planilhas. Once they are opened a prompt will appear asking them to enable the built-in scripts. If this is done the miner code will be launched.
  • aplicação instaladores — The hackers can embed the miner code in setup files of popular software. Exemplos incluem utilitários do sistema, productivity applications and creativity solutions.
  • Seqüestradores de navegador — These are malicious extension made for the popular web browsers. These strains are uploaded to their respective repositories and include counterfeit user reviews and even developer credentials. Their descriptions will promote feature additions and various performance optimizations in order to coerce the users into installing them. When this is done modifications to the browser settings will be made to redirect the victims to a hacker-controlled site. Following this step the miner will be loaded.

AcruxMiner — Analysis

It will connect to a hacker-controlled server using a preset configuration. Será “feedthe machine complex mathematical tasks that take advantage of the available hardware resources. The miner samples have been found to take advantage of both the CPU and video card (GPU) along with the memory and hard disk space. The advanced and higher tier miner has a few additional features:

  • Custom Mining Algorithm — The updated and higher tier AcruxMiner strains can scan the system and generate a report of the installed hardware components. According to the list an optimized algorithm will be selected to optimize performance.
  • Instalação persistente — The AcruxMiner malware can be installed in a way which will modify the operating system and boot configuration options in order to automatically start the engine every time the computer starts. A consequence is the inability to access certain recovery menu, this can render most manual removal instructions non-working.

The AcruxMiner malware uses an encrypted wallet which cannot be accessed by the users or system administrators. It is only used to collect and synchronize the generated income. All captured versions also feature an auto-infect capability that will scan the computer for any connected removable devices. If such are found they will be infected.

Other options available to the threat include the ability to monitor the clipboard and also interact with the Windows volume manager and network shares. This allows the miner to spread to other hosts on the local network thus being a localized botnet.

It is very possible that the perpetrators of the miner originate from Russia as the network connections to the miner servers are primarily to Russian IP addresses.

The captured samples associated with the threat also include a componente Trojan that will set-up a secure connection to a hacker-controlled server. This allows the operators to spy on the victim machines, execute certain commands and also infect them with additional payloads.

Other signatures under which the threat is known includes the following:
