New Chrome Password Stealer Sends Stolen Data to a MongoDB Database

[steven36]

A new trojan has been discovered that attempts to steal passwords stored in the Google Chrome browser. While this is nothing unique, what stands out is that the malware uses a remote MongoDB database to store the stolen passwords.

 

 

 

This trojan is called CStealer, and like many other info-stealing trojans, was created to target and steal login credentials that were saved in Google Chrome's password manager.

After being discovered by MalwareHunterTeam and further analyzed by James, though, things got a bit more interesting.

 

Instead of compiling the stolen passwords into a file and sending them to a C2 under the attackers control, the malware connects directly to a remote MongoDB database and uses it to store the stolen credentials.

 

To do this, the malware includes hardcoded MongoDB credentials and utilizes the MongoDB C Driver as a client library to connect to the database.

 

Hardcoded MongoDB Credentials

 

When passwords are stolen, the malware will connect to the database and store the passwords as seen by the network traffic created after it was tested by James.

While this method ultimately serves its purpose of stealing passwords, it also opens the door for other attackers to gain access to the victim's credentials.

 

Anyone analyzing this malware, whether it be law enforcement, researchers, or other threat actors, can retrieve the hard coded credentials and use them to gain access to the stolen credentials.

Since Google Chrome are using the Chromium platform, any Chromium-based browser (such as Edge Chromium, Opera, Brave, etc.) will be likely affected by it.

 

And if there's a vulnerability on the password manager itself, it needs to be patched.
