"New mail server system 4.0" email scam in detail

The "new mail server system 4.0" scam letters request recipients to update their email accounts since the provider has upgraded to a new mail server system. Older and inactive email accounts will be deleted; hence, recipients are urged to verify and update theirs.

As mentioned in the introduction, these letters are fake, and they promote a phishing website that is disguised as an email account sign-in page. Users can have their email accounts stolen and experience other issues by attempting to log in through this site.

Emails are particularly targeted by scammers and cyber criminals, as they are typically connected to (i.e., used to register) other accounts, platforms, services, etc. Therefore, through hijacked emails - access/control may be gained over the content associated with them.

To elaborate, communication platforms (e.g., emails, social networking, messengers, etc.) can be used to proliferate malware by sharing malicious files and links. Alternatively, scammers may assume the genuine owner's identity and ask their contacts for loans. Finance-related accounts (e.g., online banking, e-commerce, digital wallets, etc.) can be used to make fraudulent transactions and/or online purchases.

In summary, trusting the "new mail server system 4.0" scam emails can result in severe privacy issues, financial losses, and even identity theft.

Spam campaigns in general

"You have a new message due", "Outlook Email Quota email scam", "Voicemail email scam", "UN Covid-19 stimulus package" - are some examples of phishing spam campaigns.

Deceptive emails are used for various scams. Furthermore, these letters are also employed to distribute malware (e.g., ransomware, trojans, cryptocurrency miners, etc.). Due to how widespread spam mail is, it is strongly recommended to exercise caution with incoming emails and messages.

How do spam campaigns infect computers?

Spam emails can have infectious files as attachments or download links. These files can be in various formats, e.g., archives (ZIP, RAR, etc.), executables (.exe, .run, etc.), Microsoft Office and PDF documents, JavaScript, and so on. When the files are opened - the infection process is jumpstarted.

For example, Microsoft Office documents cause infections by executing malicious macro commands. This process is triggered when a document is opened in Microsoft Office versions released before 2010. "Protected View" mode prevents this in newer versions; instead, users can manually enable macros (i.e., editing/content). It is noteworthy that malicious documents often contain deceptive messages designed to trick users into enabling macros.

How to avoid installation of malware?

To avoid infecting the system through spam mail, it is advised against opening suspicious/irrelevant emails - especially any attachments or links found in them. It is recommended to only use Microsoft Office versions released after 2010.

Aside from spam emails, malware is also spread via dubious download channels (e.g., unofficial and freeware sites, Peer-to-Peer sharing networks, etc.), illegal activation tools ("cracks"), and fake updates. Therefore, it is crucial to always download from official/verified sources and activate/update programs with tools provided by genuine developers.

It is paramount to have a reputable anti-virus installed and kept updated. This software has to be used to perform regular system scans and to remove threats. If you've already opened malicious attachments, we recommend running a scan with Combo Cleaner Antivirus 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".

Delete malware in Autoruns

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.

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 Combo Cleaner Antivirus for Windows.
