"Monthly Email Validation" email scam removal guide

What is the fake "Monthly Email Validation" email?

"Monthly Email Validation" is the name of a phishing spam campaign. This term defines a large-scale operation during which thousands of deceptive emails are sent. These scam letters claim that certain functionalities of recipients' email accounts are unavailable due to it failing the "monthly validity check" test. The hoax emails urge recipients to perform the test manually - to restore the mailbox's supposedly restricted features. The aim of this spam campaign is to promote a phishing website, which is presented as a mail account log-in page. Information (i.e., email addresses and passwords) entered into this site are inadvertently exposed to the scammers behind the "Monthly Email Validation" letters, thereby allowing them to steal the corresponding accounts.

Monthly Email Validation email spam campaign

The "Monthly Email Validation" scam emails (subject/title "PERFORM VALIDITY CHECK") state that recipients' email accounts failed the automatic validity test. Due to this, some activities are restricted until the validation process is completed successfully. To recover the mailboxes' functionalities, recipients are informed that they must perform the validity check manually. The "PERFORM VALIDITY CHECK" button in these letters - redirects to a phishing webpage. Log-in credentials (i.e., email addresses and passwords) provided to this site are disclosed to the scammers. Therefore, the corresponding email accounts can be stolen.

Emails are especially targeted by scammers and cyber criminals, as these accounts are usually connected with others. Hence, through hijacked mail, access/control may be gained over platforms and services registered via the email. To elucidate how they can be used, then communication accounts (e.g., emails, social networking, social media, messengers, etc.) can be used to spread malware by sharing infectious files. Alternatively, scammers can use these platforms to ask contacts, friends, or followers for loans - under the guise of the genuine owner. Financial-related accounts (e.g., banking, online money transferring, e-commerce, digital wallets, etc.) can be used to make fraudulent transactions and/or online purchases. To summarize, by trusting the "Monthly Email Validation" scam letters - users can experience severe privacy issues, financial losses, and even identity theft. If attempts to log in through the phishing website have already been made, it is strongly advised to immediately change the passwords of potentially compromised accounts. Furthermore, it is recommended to contact the official support of endangered platforms.

"Kaspersky Email Scam", "$1,000 Gift Card Email Scam", "OneDrive Email Scam", and "Upgrade Account Email Scam" are some examples of spam campaigns. The scam emails are usually presented as "important", "urgent", "priority", and similar; they may even be presented as letters from legitimate companies, institutions, authorities, organizations, service providers, and other entities. Spam campaigns are not used exclusively for phishing, they are also employed to facilitate different scams and to spread malware (e.g., trojans, ransomware, etc.). The sole purpose of deceptive emails is to generate revenue for the scammers/ cyber criminals behind them. Due to the prevalence of spam mail, it is advised to exercise caution with inbound emails.

How do spam campaigns infect computers?

Systems are infected via malicious files that are distributed through spam campaigns. These files can be attached to and/or linked inside the scam emails. Virulent files can be in various formats, e.g., Microsoft Office and PDF documents, archives, executables, JavaScript, etc. When the files are executed, run, or otherwise opened - the infection process (i.e., malware download/installation) is initiated. For example, Microsoft Office documents cause infections by executing malicious macro commands. This process is triggered automatically upon the document's opening - in Microsoft Office versions released prior to 2010. Later versions have "Protected View" mode that prevents automatic macro execution. Instead, users are asked to enable editing/content (i.e., macro commands) and warned of potential threats.

How to avoid installation of malware?

Suspicious and irrelevant emails must not be opened, especially any attachments or links present in them. It is also recommended to use Microsoft Office versions released before 2010. Aside from spam campaigns, malware is proliferated via untrustworthy download channels (e.g., unofficial and free file-hosting websites, Peer-to-Peer sharing networks, and other third-party downloaders), illegal activation tools ("cracks"), and fake updaters. Therefore, it is important to only perform downloads from official and verified sources. Additionally, all programs must be activated and updated with tools/functions provided by legitimate developers. To ensure device integrity and user privacy, it is crucial to have a reputable anti-virus/anti-spyware suite installed and kept up-to-date. This software has to be used to run regular system scans and remove detected threats and issues. If you've already opened malicious attachments, we recommend running a scan with Malwarebytes for Windows to automatically eliminate infiltrated malware.

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.
