CStealer is a Trojan, and it will enter your operating system without you knowing about it. Of course, that is possible only if your system is not protected by reliable anti-malware software. If you do not use such software, or if the software you use did not keep you safe, the Trojan might have already slithered in and stolen your passwords. If you are not yet certain that this is the malware that you are currently dealing with, we advise implementing a trusted malware scanner. Click the Download button below for a free malware scanner that will quickly examine your system and let you know if you need to delete CStealer. Without a doubt, the removal of this threat cannot be postponed one minute.
Trojans can be used in various different ways. That depends on their functionality. In most cases, Trojans are meant to open up security backdoors and drop malware files. These files might be responsible for gathering information, hijacking systems, or even spreading malware further on. CStealer, however, is a Trojan that appears to have one function, and that is to steal passwords. It does not record keystrokes or capture screenshots for that, but it extracts the passwords that are saved on Google Chrome. If you go to the browser’s Settings menu, you can choose to enable Autofil, which means that all web forms are automatically filled with the information you typed in previously. You can also enable to offer to save passwords. With these settings in place, every password you save and autofill is recorded by the browser, and these are the passwords that CStealer is after.
Once your private passwords are extracted by CStealer, they are saved in a MongoDB database, where virtually anyone with the right credentials can access them. It is possible that the cybercriminals behind the infection care only about making money, in which case they might choose to sell the stolen passwords on the dark web and underground forums. In a different scenario, they could be targeting very specific systems to steal passwords of very specific users. For example, if CStealer was created to aid cyber-espionage, it could try to invade the systems of governments and large organizations. Needless to say, passwords stolen from such entities could give the attackers much more power, and they could try to hijack extremely sensitive accounts and systems. Of course, we are only speculating here, and we do not yet know if the Trojan has specific targets.
Do you know what to do if the presence of CStealer was confirmed by a malware scanner or an anti-malware tool? You want to delete this malware first, but then you want to change your passwords. You need to take care of this as quickly as possible because with every second that your passwords are exposed, you are becoming more and more vulnerable, as more and more attackers could gain access to the MongoDB database. To remove CStealer quickly, we strongly advise implementing anti-malware software. The main function of such software is to provide Windows users with reliable protection, and, needless to say, you need it to have your system guarded against Trojans and other dangerous threats. However, the instant benefit to employing anti-malware software is that it can delete existing threats automatically. Unfortunately, removing the Trojan manually can be too complicated.
Once you have CStealer removed, you need to change passwords quickly. Start with the most sensitive accounts, such as your online banking account and your main email account that multiple other could be connected to. Also, remember that if you have reused the same password, you need to change it even if it was not saved on Google Chrome. The best thing you can do is change all passwords, but you need to make sure that every single password is unique and strong. If you cannot handle this task on your own, perhaps you could employ a password manager?
