"Upgrade Account email scam" removal guide

What is the "Upgrade Account" scam email?

"Upgrade Account email scam" refers to a spam campaign - a large-scale operation during which scam emails are sent by the thousand. The letters distributed through this campaign - claim that recipients' email accounts will be deactivated if they do not update them. This deceptive mail aims to promote a phishing website, which is disguised as the email account sign-in page. Information entered into this webpage (i.e., email addresses and passwords) are recorded and sent to the scammers behind the "Upgrade Account" spam campaign.

The "Upgrade Account" scam emails (subject/title "Action Required:  [Mail Service Upgrade]") state that all outdated mail versions will be deactivated. The letters inform recipients that their email accounts are outdated. To prevent deactivation, the emails instruct to sign in and upgrade the accounts to the latest version. The "UPGRADE NOW" button redirects to a phishing site. It appears as an email sign-in page; however, instead of accessing their accounts - users inadvertently expose their log-in credentials (i.e., email addresses and passwords). Therefore, the scammers can then gain access and control over the corresponding mail accounts.

Email accounts are especially targeted by scammers and cyber criminals - as they are typically connected with other platforms and services. Hence, through stolen emails - access/control may be gained over the accounts associated with them. To elaborate on how they can be used, then on hijacked communication platforms (e.g., emails, social media, social networking, messengers, etc.), scammers can pretend to be the genuine owner and ask contacts/friends/followers for loans. Alternatively, malware can be proliferated (by sharing infectious files) through these platforms. Finance-rated accounts (e.g., banking, online money transferring, e-commerce, digital wallet, etc.) can be used to make fraudulent transactions and/or online purchases. To summarize, by trusting the "Upgrade Account" emails, recipients can experience severe privacy issues, financial losses, and identity theft. Should attempts to log-in through the scam website have already been made - it is strongly advised to change the passwords of potentially compromised accounts. Additionally, it is recommended to contact the official support of the endangered platforms.

"DENTIN METAL ENGINEERING", "GoDaddy email scam", and "Facebook Lottery" are a few examples of phishing spam campaigns. The letters sent through these mass-scale operations - are usually presented as "official", "urgent", "priority", and similar. The emails can even be disguised as mail from legitimate institutions, authorities, organizations, companies, businesses, service providers, and other entities. Spam campaigns are used for phishing, various scams, and malware (e.g., trojan, ransomware, etc.) distribution. Due to how widespread spam mail is, it is highly recommended to exercise caution with incoming emails.

How do spam campaigns infect computers?

Systems are infected via virulent files sent through spam campaigns. The files can be attached to the scam emails, and/or the letters can contain download links of infectious content. Malicious files can be in various formats, e.g., archives (ZIP, RAR, etc.), executables (.exe, .run, etc.), PDF and Microsoft Office documents, JavaScript, and so on. When these files are executed, run, or otherwise opened - the infection process (i.e., malware download/installation) is triggered. For example, Microsoft Office documents cause infections by executing malicious macro commands. This process begins the moment a document is opened - in Microsoft Office versions released before 2010. Newer versions have "Protected View" mode that prevents automatic execution of macros. Instead, users are asked to enable editing/content (i.e., macro commands) and warned of the risks.

How to avoid installation of malware?

To avoid infecting the system via spam mail, it is expressly advised against opening suspect/irrelevant emails - especially any attachments or links present in them. It is recommended to use Microsoft Office versions released after 2010. Aside from spam campaigns, malware is also spread through 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 always download from official and verified sources. Additionally, software must be activated and updated with tools/functions provided by legitimate developers. To ensure device and user safety, it is paramount to have a dependable anti-virus/anti-spyware suite installed and updated. Furthermore, these programs have to be used to perform regular system scans and remove detected/potential threats. 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.
