What Is Altrousik?

Altrousik is a type of Trojan horse malware designed to mine cryptocurrency by leveraging your computer’s resources, primarily the CPU and GPU, without your consent. It runs hidden processes in the background, using your system’s power to perform intensive cryptocurrency mining tasks. This not only slows down your computer but can also cause other serious performance issues.

Like most Trojans, Altrousik often masquerades as a legitimate application or file. Once installed, it can cause extensive damage to your system. It has the ability to steal sensitive data, expose your system to additional malware threats, and provide hackers with remote access to your device. The longer it remains undetected, the greater the risk to your personal and financial security.

Altrousik – Distribution Tactics

Altrousik is commonly distributed through various tactics employed by cybercriminals to trick users into downloading and installing the malware. The following are the most common distribution methods:

Exploit Kits

Exploit kits are tools used by cybercriminals to identify and take advantage of vulnerabilities in software on your device. Once the exploit kit finds a weakness in your system, it injects Altrousik into your machine without your knowledge.

Phishing Emails

Phishing is a popular technique where cybercriminals send fraudulent emails, often appearing legitimate, to trick recipients into clicking malicious links or downloading infected attachments. These emails can look like updates from well-known software providers or a message from a trusted contact.

Freeware Bundled with Malicious Files

Altrousik is often bundled with free software or pirated applications that unsuspecting users download from untrustworthy websites. When downloading and installing free software, be cautious about the additional files or applications that come with it, as these may include Trojans like Altrousik.

Fake Updates or Harmful Websites

Cybercriminals also use fake updates or deceptive websites to trick users into installing Altrousik. These sites may look legitimate and prompt you to update your browser or plugins, but clicking on the update link could result in malware installation.

What Does Altrousik Do?

Once Altrousik infiltrates a system, it creates several harmful files that can seriously damage the computer and network. Its primary goal is to use your system resources to mine cryptocurrency, but it doesn’t stop there. The Trojan also acts as a backdoor for other types of malware.

Here are some of the key actions Altrousik takes after infection:

1. Resource Consumption: Altrousik runs cryptocurrency mining processes that cause your CPU and GPU to overwork, leading to a significant slowdown of your computer. In some cases, the system may even freeze or overheat due to the strain.
2. Backdoor for Other Malware: Altrousik often acts as a gateway for other types of malware to enter your system. This includes ransomware, spyware, adware, and even additional Trojans. By creating a backdoor, it allows cybercriminals to install further malicious software without your knowledge.
3. Data Theft: As an infostealer Trojan, Altrousik is capable of stealing sensitive information, such as login credentials, banking details, or any personal data that could be exploited. It can also hijack email accounts to send spam messages to your contacts.
4. Online Fraud: Cybercriminals may use the information stolen by Altrousik to commit fraud or engage in identity theft. This can result in severe financial losses for victims.

How to Remove Altrousik Trojan

Removing Altrousik is crucial to protecting your system from further damage. If you suspect that your computer is infected with this Trojan, follow these steps for complete removal.

Step 1: Run a Full System Scan

The first and most essential step is to run a comprehensive scan using trusted anti-malware software, such as SpyHunter, to detect and identify Altrousik. Make sure your anti-malware tool is up-to-date so that it can detect the latest variants of this Trojan.

Step 2: Isolate the Infected Device

If you detect the presence of Altrousik, disconnect the infected device from the internet to prevent further data theft or the installation of additional malware. This action will also stop the Trojan from communicating with its command-and-control servers.

Step 3: Remove Malicious Files

Use your anti-malware software to quarantine and delete any malicious files associated with Altrousik. Make sure to remove any lingering files, as they could leave your system vulnerable to reinfection.

Step 4: Restore System Settings

After removing the Trojan, reset any settings that may have been altered, such as browser configurations or network settings. Altrousik may have altered these settings to gain persistent access to your system.

Step 5: Update Your Software

Altrousik often exploits vulnerabilities in outdated software. Ensure that all your programs, especially your operating system, browsers, and security software, are fully updated to patch any security holes that could be exploited by the malware.
