What is Dridex?

Dridex (also known as Bugat and Cridex) is a malicious program that is used to steal banking credentials from users of Windows computers. Cyber criminals proliferate this rogue software when it is downloaded and installed through a malicious Microsoft Word or Excel document. Once installed, it targets banking information. Therefore, users with computers infected by Dridex are likely to experience financial loss.

Dridex malware

The main goal of this malware is to steal sensitive details relating to victims' bank accounts, such as online banking credentials. Therefore, this malicious software helps distributors and cyber criminals to access victims' bank accounts and make fraudulent transactions - effectively stealing money from unsuspecting people. This malicious software operates as a key logger and records keystrokes (keys pressed). Cyber criminals seek to infect computers with these key loggers so they can steal logins, passwords, and other sensitive details, including banking credentials. This program is also capable of performing several 'injection attacks'. These attacks allow injection of malware into a computer system to execute remote commands or inject code into a specific program and modify its execution/behavior. Furthermore, the latest Dridex variant is difficult to detect, since it is capable of evading anti-virus detections. It uses file signatures that go undetected as threats, and thus Dridex bypasses virus detection engines. Additionally, this malware uses an Application Whitelisting technique to block elements of WSH (Windows Script Host). It takes advantage of a WMIC (WMI command-line) flaw by targeting a weak spot (execution policy) in the application whitelisting process. To bypass mitigation efforts, Dridex malware loads XLS scripts that contain malicious Visual Basic Script. In summary, this is advanced malware, which is goes undetected. If you have reason to believe that your computer is infected with Dridex, remove it immediately.

There are a number of malware infections used to steal personal details. Some examples are Emotet, Adwind, FormBook, and AZORult. Typically, cyber criminals spread these programs to generate revenue by stealing personal details, distributing other malware such as ransomware, and so on. These programs can cause serious problems (financial, data loss, privacy issues, etc.). For this reason, it is important to eliminate them immediately.

How did Dridex infiltrate my computer?

Research shows that cyber criminals poliferate Dridex through spam campaigns. They send emails that contain attached Microsoft Word or Excel files. Typically, these emails are presented as official and important. In our example, the email is disguised as a message regarding an invoice. The main purpose of this spam campaign is to trick people into opening the attached file, which then causes download and installation of a malicious program. In this case, an MS Office file infects computers with Dridex. Typically, these files demand permission to enable macro commands (thus allowing content/editing). Once this permission is given, a document starts downloading (and then installing) malicious software. In summary, these documents cannot do any damage unless they are opened and permission to enable macros is granted. Other examples of files that cyber criminals send to proliferate malware are PDF documents, JavaScript files, executables (.exe files), and archive files such as ZIP and RAR.

How to avoid installation of malware?

Be careful with files that are attached to emails received from suspicious or unknown email addresses. Typically, these emails are irrelevant and disguised as 'important'. The best way to deal with them is to ignore them and leave files and links within them unopened. Download software and files from official websites and use direct download links. Third party downloaders, unofficial websites, various Peer-to-Peeer networks should not be trusted. Downloading files or programs via these sources might lead to computer infections. Keep installed programs and operating systems up-to-date, however, use implemented functions or tools created by official developers only. Do not activate installed programs with 'cracking' tools, since this is illegal and they are often designed to distribute malicious programs (infect computers with malware). Have a reputable anti-virus or anti-spyware suite installed and enabled at all times. If you believe that your computer is already infected, we recommend running a scan with Spyhunter for Windows to automatically eliminate infiltrated malware.

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 Spyhunter for Windows.
