What is RedLine Stealer?

RedLine Stealer (also known as RedLine) is a malicious program which can be purchased on hacker forums for $150/$200 depending on the version. It can be used to steal information and infect operating systems with other malware. Generally, cyber criminals attempt to infect computers with malicious software such as RedLine Stealer to generate revenue by misusing accessed (stolen) details and/or by infecting systems with other software of this type to achieve the same purpose. If there is any reason to suspect that your computer is infected with RedLine Stealer, remove it immediately.

RedLine Stealer malware

RedLine Stealer is capable of gathering information such as logins, passwords, autofill data, cookies and credit card details from all Gecko-based and Chromium-based web browsers. Cyber criminals can misuse this information to access various accounts (e.g., social media, email, banking-related accounts, cryptocurrency wallets). They also misuse them to proliferate malware, spam campaigns, make fraudulent transactions and purchases, deceive other people into transferring money, steal identities, and so on. RedLine Stealer can collect data from various FTP (File Transfer Protocol) and IM (Instant Messaging) clients and grab files stored on the infected computers. Furthermore, it is capable of collecting system information such as IP addresses, usernames, keyboard layouts, UAC settings, installed security solutions, and other details. This malicious program can be used to infect computers with other malware (download and execute malicious files). Therefore, cyber criminals can use RedLine Stealer to distribute ransomware, Trojans, cryptocurrency miners, Remote Access/Administration Trojans (RATs) and so on. Ransomware-type programs encrypt files (cause data loss), Trojans can cause chain infections (install other malware), cryptocurrency miners use computer hardware to mine cryptocurrency, and RATs allow criminals to take control over the infected computer and perform dangerous tasks. In summary, RedLine Stealer victims can suffer financial, data loss, become victims of identity theft, experience problems with privacy, and other serious issues. Therefore, if RedLine Stealer is installed on your computer, it must be uninstalled immediately.

Some examples of other malware programs similar to RedLine Stealer include CStealer, Masad and Krypton. In most cases, these programs are capable of accessing (collecting) various sensitive, confidential information (logins, passwords, credit card details, etc.), which cyber criminals misuse to generate as much revenue as possible. Having this software installed on your computer can lead to serious issues. Therefore, to avoid installation, take the necessary precautions detailed below.

How did RedLine Stealer infiltrate my computer?

Typically, cyber criminals proliferate malicious programs through spam campaigns (emails), Trojans, dubious software download channels, unofficial activation tools and fake updaters. They attempt to proliferate malware by sending emails that contain malicious attachments (or web links that lead to download of malicious files). Cyber criminals usually attach Microsoft Office, PDF documents, archive files (RAR, ZIP), executable files (.exe and others) and JavaScript files. If opened, the attached files install malicious software. Trojans often proliferate and install other malware and cause chain infections, however, they must first be installed. Untrustworthy download sources/channels are used to trick users into installing malware by disguising hosted, uploaded malicious files as harmless and regular. When downloaded and opened/executed, however, the files cause installation of malware. Some examples of the download channels often used to proliferate malicious programs are free file hosting, freeware download websites, unofficial sites, Peer-to-Peer networks (e.g., torrent clients, eMule) and third party downloaders. Unofficial activation tools supposedly activate licensed software free of charge (bypass its activation), however, they often install malware instead. Fake software update tools cause damage by installing malicious software rather than updates or exploiting bugs/flaws of outdated software that is installed on the operating system.

How to avoid installation of malware

Software and files should not be downloaded or installed through third party downloaders, installers, Peer-to-Peer networks or the other channels/tools mentioned above. Downloaded only from official websites and via direct links. Irrelevant emails that are received from unknown, suspicious addresses and contain attachments/links should not be trusted (do not open the contents). Installed software must be updated and activated through tools or functions that are designed by official developers. Third party, unofficial tools are often used to proliferate malicious software. Furthermore, it is illegal to bypass activation of licensed software with unofficial activation ('cracking') tools. Operating systems should be regularly scanned fo threats with reputable antivirus or anti-spyware software. Keep this software up to date. If you believe that your computer is already infected, we recommend running a scan with Malwarebytes for Windows to automatically eliminate infiltrated malware.

Update 20 March 2020 - Cyber criminals have recently started a new spam email campaign to distribute RedLine Stealer. They send thousands of deceptive emails asking for help to perform medical research relating to the coronavirus. They ask users to install software that will supposedly use the recipient's computer to perform various calculations and, thus, help the researchers. The app they encourage users to install is called Folding@home. This application exists and is legitimate, however, this spam campaign is a deception - rather than installing the Folding@home application, criminals inject RedLine Stealer into the system. You can find more details in Lawrence Abram's article posted in Bleeping Computer.

Update 3 November 2020 - It is known that cyber criminals now use fake Inno Setup installers for TeamViewer to distribute RedLine stealer. Those installers are designed to execute the "wmiprvse.exe" file, which loads the malicious "msi.dll" that contacts the malicious URL that hosts the RedLine password stealer malware.

How to remove malware manually?

Manual malware removal is a complicated task - usually it is best to allow antivirus or anti-malware programs to do this automatically. To remove this malware we recommend using Malwarebytes for Windows. If you wish to remove malware manually, the first step is to identify the name of the malware that you are trying to remove. Here is an example of a suspicious program running on a user's computer:

If you checked the list of programs running on your computer, for example, using task manager, and identified a program that looks suspicious, you should continue with these steps:

manual malware removal step 1Download a program called Autoruns. This program shows auto-start applications, Registry, and file system locations:

extract autoruns.zip and run autoruns.exe

manual malware removal step 4In the Autoruns application, click "Options" at the top and uncheck "Hide Empty Locations" and "Hide Windows Entries" options. After this procedure, click the "Refresh" icon.

Click 'Options' at the top and uncheck 'Hide Empty Locations' and 'Hide Windows Entries' options

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.
