CStealer malwareCStealer virus is a trojan infection that can relate in data theft and money swindling

CStealer virus is a trojan that steals passwords from Google Chrome and delivers them to the MongoDB database. Thoroughly investigated by a malware researcher known as James,[1] the Trojan virus uses the MongoDB C driver to deliver the collected passwords to the MongoDB database where account credentials are included. This provides the opportunity for other remote hackers to investigate the malware and the credentials that might lead to the exposure of data that is stored in the MongoDB database. We can only think of what the criminals might do next. CStealer might be used for exposing personal information, stealing big amounts of money directly from victims' banking accounts, or infiltrating other parasites.

CStealer trojan has been discovered by 43 AV engines out of the total 69, according to the latest information by VirusTotal.[2] Popular AV engines such as BitDefender, Malwarebytes, AVG, Kaspersky, and others detect this malware string during the computer checkup process.

However, finding CStealer with the help of antivirus software is much easier than recognizing the infection by yourself. Usually, trojans do not show any signs at first that would be identified as malicious symptoms. However, if you spot some of the following signs, be quick to perform a malware scan as a virtual parasite might be compromising your PC:

  • An immediate increase of the CPU power;
  • Unnoticeable processes running in the Task Manager;
  • Very similar two processes running in the Task Manager;
  • Bogus Registry entries that you do not recall installing;
  • Slow computer work, freezing windows, and software.

If you see at least one or two of these signs, do not hesitate and run a malware scan with a reliable tool as you might need to perform the CStealer virus removal even if you do not think so. These programs tend to act very discreetly while hiding their true purposes and operating in the background of the user's activities.

As we have already mentioned, CStealer steals passwords that have been stored in Google Chrome and this can be very dangerous. The criminals might be able to access some of your online accounts and misuse the information that is located there. For example, these people might log into your Facebook account and start delivering malware to your friends.

Continuously, if CStealer finds any banking or credit card information, it might not take long for the hackers to empty your bank account. This way you might experience huge monetary losses (with no return) or see that you have purchased various products and services that you do not remember ordering.

You should not play with dangerous malware or postpone the removal process as it might completely ruin your computer system, software, finances, your friends' computers, etc. Use strong software to remove CStealer virus from your machine. For fixing damaged system objects, you can try using a program such as ReimageIntego.

The most popular malware distribution techniques and how to avoid virtual parasites

Security experts from Virusai.lt[3] state that trojans and other malware are commonly distributed via p2p websites such as The Pirate Bay, eMule, and BitTorrent. The parasite comes in a software crack and aims to place itself on computer systems that have a weak security level.

This is one of the main reasons why installing strong antivirus protection on your machine is necessary. These tools will regularly scan your computer system, search for cyber threats, and alert if anything bad has been discovered.

Continuously, Trojan viruses can be spread via phishing email messages that claim to arrive from reputable companies and organizations. The crooks often pretend to be from FedEx/DHL and attach an executable, word document, or PDF file to the email message where the malicious payload lies.

A tip would be to always investigate your received email carefully. Check the sender and the content of the message. If you get any concerns, delete the letter right away. Also, never open a questionable attachment that you were not expecting to receive without scanning it with antimalware software.

It is better to remove CStealer virus only automatically

We do not recommend performing CStealer virus removal on your own as you risk making mistakes or skipping some infected components. Employ software such as SpyHunter 5Combo Cleaner and Malwarebytes to find out all malicious strings in your Windows system. Afterward, you can try repairing the system with ReimageIntego.

It might not be that easy to permanently remove CStealer virus when it is running malicious processes on your computer system that have been provoking the program to run repeatedly or evade antivirus detection. To dimish all malicious activities, you should boot your machine in Safe Mode with Networking or enable System Restore. If you do not know how to do that, you can check the following guidelines that are provided by our security specialists.

How to prevent from getting malware

Access your website securely from any location

When you work on the domain, site, blog, or different project that requires constant management, content creation, or coding, you may need to connect to the server and content management service more often. The best solution for creating a tighter network could be a dedicated/fixed IP address.

If you make your IP address static and set to your device, you can connect to the CMS from any location and do not create any additional issues for the server or network manager that needs to monitor connections and activities. VPN software providers like Private Internet Access can help you with such settings and offer the option to control the online reputation and manage projects easily from any part of the world.

 

Recover files after data-affecting malware attacks

While much of the data can be accidentally deleted due to various reasons, malware is one of the main culprits that can cause loss of pictures, documents, videos, and other important files. More serious malware infections lead to significant data loss when your documents, system files, and images get encrypted. In particular, ransomware is is a type of malware that focuses on such functions, so your files become useless without an ability to access them.

Even though there is little to no possibility to recover after file-locking threats, some applications have features for data recovery in the system. In some cases, Data Recovery Pro can also help to recover at least some portion of your data after data-locking virus infection or general cyber infection.
