What is SendGrid Email Scam?

Scammers behind this spam campaign attempt to trick recipients into believing that this email is sent from SendGrid (a legitimate email marketing company) and entering their login credentials into a fake SendGrid login page. The SendGrid company has nothing to do with this scam and, therefore, you should ignore this email.

SendGrid Email Scam email spam campaign

The email states that an invoice payment has been submitted by SendGrid to pay for services purchased from this email marketing company. The main purpose of scammers behind this scam is to deceive people into opening a fake SendGrid login page and entering their usernames and passwords.

In this way, they attempt to steal SendGrid accounts and misuse them for malicious purposes (e.g., to make fraudulent purchases, sell stolen accounts to third parties).

Many people use identical usernames and passwords for multiple accounts and, therefore, entering SendGrid login credentials into that fake website can result in loss of access to other personal accounts as well. You are strongly advised not to trust emails of this kind and/or enter login credentials (or other sensitive information) on unofficial, dubious websites.

More examples of email scam campaigns are "Your Email Is Out Of Date Email Scam", "Mail Quota Email Scam" and "Your Account Has Encountered An Error 505 Email Scam". In most cases, the emails are sent by cyber criminals who attempt to steal sensitive information, trick recipients into sending money, etc.

The emails can be used to proliferate malware (for example, ransomware, Trojans). They succeed when recipients open a malicious attachment or a file downloaded via malicious link that was sent to them.

How do spam campaigns infect computers?

Typically, users are tricked into installing malware through malspam campaigns when they execute a malicious file that was attached to the email. In some cases, cyber criminals send emails with website links designed to download malicious files or open their download pages.

They commonly send emails that have a malicious PDF, Microsoft Office document, JavaScript file, executable file (.exe) or archive file (ZIP, RAR) attached to them. Note that malware is installed via MS Office documents only when users enable macros commands (enable editing/content).

When such documents are opened with MS Office that was released before 2010, they install malware automatically, since these versions do not include "Protected View" mode, which prevents malicious documents from installing malware without permission.

How to avoid installation of malware

You are advised not to open files (attachments) or website links that are sent from suspicious, unknown email addresses, especially if the emails are irrelevant. Files and software should be downloaded from official websites and through direct download links. Other sources should not be used.

Examples of dubious download channels are unofficial pages, third party downloaders, Peer-to-Peer networks such as torrent clients, eMule, etc. Also avoid third party installers to install software. Furthermore, installed programs must be activated and updated with official tools or implemented functions, and not third party, unofficial updating and activation tools.

The use of third party activation 'cracking' tools is illegal. Regularly scan the operating system with reputable antivirus or anti-spyware software and keep it up to date. If you have already opened malicious attachments, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate infiltrated malware.

How to remove malware manually?

Manual malware removal is a complicated task - usually it is best to allow antivirus or anti-malware programs to do this automatically.

To remove this malware we recommend using Combo Cleaner Antivirus for Windows. If you wish to remove malware manually, the first step is to identify the name of the malware that you are trying to remove. Here is an example of a suspicious program running on a user's computer:

manual malware removal step 4In the Autoruns application, click "Options" at the top and uncheck "Hide Empty Locations" and "Hide Windows Entries" options. After this procedure, click the "Refresh" icon.

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 Combo Cleaner Antivirus for Windows.
