E-Mail Clustered email scam removal guide

What is E-Mail Clustered email scam?

It is common that scammers use email to trick recipients into providing some personal, sensitive information like credit card details, login credentials for various accounts, etc. Usually they attempt to do so by disguising their emails as official, important letters from legitimate companies, organizations. This particular email scam is disguised as a letter from email service provider and used to to trick recipients into providing their email account login credentials.

E-Mail Clustered email scam email spam campaign

Scammers behind this scam send emails saying that certain number of other emails cannot be delivered to due to a recent configuration error. Their main goal is to trick recipients into believing that they can solve this problem by approving pending emails via the provided website link. That link is designed to open a page where visitors are asked to enter login credentials for their email account. It is worthwhile to mention that recipients who would enter their credentials on that page may lose access not only to their email accounts but also to other accounts that can be accessed with the same credentials.

Stolen accounts could be misused to trick other users into making money transactions, spread this phishing email further, send malspam emails, steal identities, personal information like credit card details, telephone numbers, names, surnames, addresses, and for other malicious purposes. Also, stolen accounts and/or information could be monetized by selling it to third parties (other cyber criminals). Either way, it is strongly recommended not to trust emails like this one or enter credentials on unofficial, suspicious or untrustworthy in any other way websites.

There are many examples of emails scams that are (or were) used to trick recipients into providing sensitive information. Some of them are "Email Verification Scam", "Message Attachments Were Delayed Email Scam" and "Deactivating All Inactive Accounts Email Scam". It is worthwhile to mention that emails can be used to trick recipients into installing malware (e.g., ransomware, Trojan-type malware) as well.

How do spam campaigns infect computers?

Recipients infect computers with malware via malspam when they open malicious attachments, or files that they have downloaded via links in such emails. Examples of files that that can be used to distribute malware via email can be malicious executable files (like .exe), JavaScript files, PDF, Microsoft Office documents, archive files (like ZIP, RAR). It is worthwhile to mention that malicious Microsoft Office files infect systems only if recipients enable editing/content (macros commands) in them. Although, it does not apply to malicious documents that users open with MS Office versions that were released after year 2010 - those documents infect computers with malware automatically because the aforementioned versions do not include the "Protected View" mode.

How to avoid installation of malware?

It is strongly recommended to update and activate installed software only with tools that are designed by its official developers. It is worthwhile to mention that it is not legal to use unofficial activation ('cracking') tools to activate licensed software (or use installers for pirated software). Also, it is advised not to open links or attachments in irrelevant emails that are received from unknown, suspicious addresses. Software, files should be downloaded only from official websites and via direct links. Peer-to-Peer networks, unofficial pages, third party downloaders (and installers), etc., should not be used. Additionally, it is recommended to scan a computer for threats regularly and use an up-to-date, and reputable antivirus or anti-spyware software. If you've already opened malicious attachments, 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.
