"BBVA" email virus removal guide

What is the "BBVA" email?

"BBVA" is a deceptive email, designed to proliferate the Agent Tesla RAT (Remote Access Trojan). The text presented in these letters is in Spanish, hence the indented targets are Spanish-speaking users. The emails claim to contain information concerning due invoice payments. Instead the attached archived file has the malicious executable of Agent Tesla. RAT-type malware enables remote access and control over an infected system, thereby posing a serious threat to device and user safety.

BBVA malware-spreading email spam campaign

The emails with the subject "BBVA-Confirming Facturas Pagadas al Vencimiento" (titles may vary) state that they have information regarding due invoice payment enclosed within them. However, the attached archived file, named "Facturas Pagadas al Vencimiento.rar" - contains "xoRvDdUQHgkjftOkPt.exe"; when this file is opened - it initiates the infection process. In other words, download/installation of Agent Tesla begins. As mentioned in the introduction, Remote Access Trojans allow cyber criminals to remotely access and control the infected device. The primary purpose of Agent Tesla is stealing information. This endeavor is carried out through the malware's ability to record key strokes (keylogging). Said functionality is typically used by cyber criminals to steal log-in credentials (i.e. usernames and passwords) of various accounts. For example, to hijack email, messaging, social networking, social media, online data storage, e-commerce, online money transfer, banking and other accounts. Therefore, Agent Tesla infections can lead to financial losses, severe privacy issues and identity theft. It is expressly advised against trusting the "BBVA" scam emails. If it is suspected/known that Agent Tesla RAT has already infected the system, an anti-virus must be used to remove it immediately.

Deceptive/Scam emails are distributed by the thousand, during large scale operations called "spam campaigns". "Apex Enquiry", "Chorus Union", "Secret Love" and "WeTransfer" are a few examples of malware-proliferating spam campaigns. These emails are typically disguised as "official", "important", "urgent" or otherwise priority mail. However, these letters can have other purposes, such as phishing. Regardless, deceptive emails have the same end-goal - to generate revenue for the scammers / cyber criminals behind them.

How did "BBVA Email Virus" infect my computer?

Systems are infected through virulent files attached to scam emails. Alternatively, they can contain download links of infectious files or ones leading to malicious websites. These files can be in various formats, e.g. archives (ZIP, RAR, etc.), executables (.exe, .run, etc.), Microsoft Office and PDF documents, JavaScript, etc. Once they are opened - the infection process (i.e. download/installation of malware) is initiated. For example, Microsoft Office documents cause infections by executing malicious macro commands. This process begins automatically upon the document being opened in MS Office versions released prior to 2010. However, in newer versions users are asked to enable macros (i.e. to enable editing/content). Therefore, only if users allow the macro commands to be enabled does the infection process begin.

How to avoid installation of malware?

It is strongly advised against opening suspicious and/or irrelevant emails, especially any attachments or links present in them - as doing so can lead to a high-risk infection. Additionally, it is recommended to use Microsoft Office versions released after 2010. These versions possess the "Protected View" mode, which prevents infection processes from being started the very moment a malicious document is opened. Aside from spam campaigns, malware is also proliferated through untrustworthy download sources (e.g. unofficial and free file-hosting sites, Peer-to-Peer sharing networks and other third party downloaders), illegal activation ("cracking") tools and fake updates. Therefore, only official and verified download channels must be used. Furthermore, it is just as important to activate and update software with tools/functions provided by legitimate developers. To protect device and user safety, it is paramount to have a dependable anti-virus/anti-spyware installed. These programs must be kept up-to-date, used to run regular system scans and to remove detected/potential threats. If you've already opened "BBVA Email Virus" attachment, we recommend running a scan with Malwarebytes 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 Malwarebytes for Windows.
