What is CollectorStealer?

CollectorStealer (also known as DCStealer) is malicious software which allows cyber criminals to steal various sensitive information (e.g. passwords, credit card details) and files. This malware is for sale on a hacker forum for $12 or $75 (depending on the subscription type). It is advertised on the aforementioned forum as a "top-end information stealer" with a Russian interface.

Using CollectorStealer, cyber criminals can collect passwords, cookies, credit card details, autofill forms from Chromium browsers, passwords from Edge and and Mozilla Firefox, .dat and .wallet files (files from cryptocurrency wallets), Discord and Telegram sessions, passwords from FileZilla, pidgin passwords and chat history, Steam files and information relating to installed games, 2FA authenticator sessions, steal PSI/PSI+ and NordVPN accounts. It can also be used to access and record files that are stored on the victim's desktop and take screenshots. Essentially, this information stealer targets files and details that could be misused to access various accounts, make fraudulent transactions and purchases, steal identities and for other similar malicious purposes. Victims of a CollectorStealer attack might lose access to various personal accounts (such as email, social media, banking accounts), become victims of identity theft, suffer monetary loss, experience issues relating to online privacy. Stolen accounts could also be used to spread CollectorStealer further or deceive other users into installing other malware on their computers (e.g., ransomware, Trojans), transfer money to cyber criminals behind CollectorStealer. If you have inadvertently installed CollectorStealer onto the operating system, eliminate it immediately.

More examples of malware that is designed and used by cyber criminals to steal sensitive data are Mist, VikroStealer and TroyStealer. Commonly, software of this type is capable of evading detection and can run stealthily in the system background. Therefore, victims are often unaware that a computer is infected until some damage is done (such as fraudulent purchases/transactions).

How did CollectorStealer infiltrate my computer?

Typically, malware is distributed via spam campaigns, fake software updaters, untrusted software download channels, unofficial software activators and Trojans. Cyber criminals often attempt to deceive users into installing malware on computers by sending emails that include malicious attachments (or website links that download malicious files). Typically, they attach malicious Microsoft Office documents, archive files (ZIP, RAR), PDF documents, JavaScript files, and executable files (.exe). When opened/executed, the files install a malicious program, in this case, ransomware. Unofficial, fake updaters infect operating systems by installing malware rather than updating installed programs, or by exploiting bugs/flaws of outdated software. Untrusted software download channels such as unofficial web pages, Peer-to-Peer networks (torrent clients, eMule), various free file hosting, and so on, are often used to distribute malicious files. In most cases, the files are disguised as legitimate and regular. When downloaded and opened, however, they cause installation of high-risk malware. Software 'cracking' tools (third party activators) supposedly illegally activate paid software free of charge, however, rather than activating any software, these tools can install malicious software. Trojans are programs that often proliferate other malware. If a malicious program of this type is installed on the operating system, it is very likely that it will install other, similar software.

How to avoid installation of malware

Do not open a files or website links that are attached to irrelevant emails, especially if the emails are received from unknown, suspicious addresses. Software and files should be downloaded only from official websites and via direct links. The other sources/tools mentioned above can distribute malicious files and software. Installed programs must be updated and activated only with implemented functions/tools provided by official software developers. Furthermore, it is illegal to activate software with unofficial ('cracking') tools. Have a reputable anti-spyware or antivirus suite installed on the operating system and use it regularly for scans. If you believe that your computer is already infected, we recommend running a scan with Combo Cleaner Antivirus 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 Combo Cleaner Antivirus for Windows.
