What is ArkeiStealer?

ArkeiStealer (also known as Arkei Stealer) is a type of malware that steals sensitive, confidential information, which cyber criminals can then use to generate revenue. Research shows that ArkeiStealer is capable of stealing login credentials and cryptocurrency wallet keys. Through accessing such information, cyber criminals can cause significant financial loss and other problems. Therefore, if there is a reason to suspect that ArkeiStealer is installed on the computer, remove it immediately.

Cryptocurrency wallets store public and private keys, which can be used monitor balances, send money and perform other operations. ArkeiStealer can be used to steal private keys and misuse them to make fraudulent transactions. Unfortunately, there is no way to reclaim lost money (cryptocurrency) or reverse the transactions. Furthermore, this malware is capable of stealing login credentials, and therefore cyber criminals can use it to hijack email, social networking, online payment and other accounts. In most cases, cyber criminals use hijacked accounts to make fraudulent transactions and purchases, deceive other people into making transactions, steal identities, spread malware (such as ransomware, Trojan-type programs) and perform other malicious actions. ArkeiStealer can be the reason behind serious online privacy issues, significant financial loss, identity theft, etc. Therefore, it must be eliminated from infected operating systems immediately.

There are many malicious programs that are designed to steal sensitive information. Some more examples include PoulightStealer, RedLineStealer and CStealer. Typically, they are designed to target data that contains confidential details. Victims who have their operating systems infected with this malware can suffer financial loss, become victims of identity theft, experience problems related to privacy, and other issues.

How did ArkeiStealer infiltrate my computer?

Malicious programs are usually proliferated through spam email campaigns, untrusted file and software download channels, fake software updating tools, Trojans and unofficial activation ('cracking') tools. Cyber criminals attempt to spread malicious software by sending emails that contain malicious attachments. They usually send emails with malicious Microsoft Office documents, archive files (ZIP, RAR), PDF documents, executable files (.exe) or JavaScript files. They seek to deceive recipients into opening/executing a malicious file, which installs malware when opened. Note that their emails can contain website links that download malicious files as well. Examples of dubious file/software download channels are Peer-to-Peer networks (torrent clients), free file hosting websites, freeware download sites, unofficial web pages, and other similar channels. These channels are used to distribute malicious files that are disguised as harmless and regular. When users download and open them, however, they infect their computers with malware. Fake software updating tools cause damage when they install malware rather than updates/fixes or, they exploit bugs/flaws of outdated software that is installed on the operating system. A Trojan is a type of malware that can cause chain infections and install other software of this kind, however, it can only spread other malware when it is already installed on the operating system. Software 'cracking' tools supposedly activate licensed programs free of charge (bypass activation), they often install malicious software instead.

How to avoid installation of malware

All software should be downloaded from official pages and via direct links. Other channels that are mentioned in paragraph above can proliferate malicious programs and should thus be avoided. The same applies to third party installers. Operating systems and other installed software must be updated with implemented functions and tools that are designed by official developers. Third party, unofficial activation ('cracking') tools can infect computers with malware. Furthermore, software activation through such tools are illegal. Do not open attachments and website links in irrelevant emails that are received from suspicious, unknown addresses - such emails are often sent by cyber criminals who seek to proliferate high-risk malware. They disguise their emails as important, official, etc. Computers should be regularly scanned for threats with up to date, reputable antivirus or anti-spyware software. If you believe that your computer is already infected, we recommend running a scan with Malwarebytes for Windows to automatically eliminate infiltrated malware.

manual malware removal step 5Check the list provided by the Autoruns application and locate the malware file that you want to eliminate.

You should write down its full path and name. Note that some malware hides process names under legitimate Windows process names. At this stage, it is very important to avoid removing system files. After you locate the suspicious program you wish to remove, right click your mouse over its name and choose "Delete".

locate the malware file you want to remove

After removing the malware through the Autoruns application (this ensures that the malware will not run automatically on the next system startup), you should search for the malware name on your computer. Be sure to enable hidden files and folders before proceeding. If you find the filename of the malware, be sure to remove it.

searching for malware file on your computer

Reboot your computer in normal mode. Following these steps should remove any malware from your computer. Note that manual threat removal requires advanced computer skills. If you do not have these skills, leave malware removal to antivirus and anti-malware programs. These steps might not work with advanced malware infections. As always it is best to prevent infection than try to remove malware later. To keep your computer safe, install the latest operating system updates and use antivirus software.

To be sure your computer is free of malware infections, we recommend scanning it with Malwarebytes for Windows.
