What is the "DENTIN METAL ENGINEERING" scam email?

"DENTIN METAL ENGINEERING" is the name of a spam campaign - a large-scale operation during which deceptive emails are sent by the thousand. The letters distributed through this campaign - are presented as invoice notifications. These scam emails aim to promote a phishing website, which is disguised as a Microsoft Office Excel file. To view the fake document, users are asked to sign-in using their email account. Phishing sites are designed to record the information entered into them; in this case - email account passwords.

The "DENTIN METAL ENGINEERING" scam letters (subject/title "invoice 073/0542021"; may vary) claim to contain an invoice. Recipients are to review it by clicking "VIEW" or "DOWNLOAD". Pressing either leads to a phishing webpage that looks like a "Protected" Microsoft Office document. To see the fraudulent file, recipients are to enter their email address and password. Any information provided to this site will be recorded and sent to the scammers behind this spam campaign, thereby allowing them to steal the corresponding email accounts. Hence, by trusting the "DENTIN METAL ENGINEERING" scam emails, recipients can lose their mail accounts and experience a variety of other serious problems.

Scammers and cyber criminals commonly target email accounts. Emails are typically connected with other platforms and services. Therefore, through hijacked mail accounts - those associated with them can be stolen. To elaborate, scammers can pretend to be the communication platforms' (e.g., email, social networking, social media, messenger, etc.) genuine owner and ask contacts/friends/followers for loans. Alternatively, these platforms can also be used to proliferate malware - by sharing infectious files and malicious website links. Finance-related 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, the "DENTIN METAL ENGINEERING" scam emails can lead to recipients experiencing 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 potentially compromised account passwords. Additionally, it is recommended to contact the official support of all endangered platforms.

"GoDaddy email scam", "Facebook Lottery", "Banca Sella email scam", and "PASSWORD EXPIRATION NOTICE" are a few examples of other phishing spam campaigns. The letters sent through these mass-scale operations - are usually disguised as "official", "important", "urgent", and similar. The goal of scam emails is to generate revenue for the scammers/ cyber criminals behind them. Spam campaigns are not used only for phishing and other scams, they are also employed to spread malware (e.g., trojans, ransomware, etc.). Due to how prevalent spam mail is, it is advised to exercise caution with incoming emails.

How do spam campaigns infect computers?

Spam campaigns proliferate malware via virulent files distributed through them. These files can be attached to the emails, and/or the letters can contain download links of such content. Infectious files can be in various formats, e.g., Microsoft Office and PDF documents, archives, executables, JavaScript, etc. When malicious files are executed, run, or otherwise opened - the infection chain (i.e., malware download/installation) is initiated. For example, Microsoft Office documents cause infections by executing malicious macro commands. In Microsoft Office versions released before 2010 - macros are executed the moment a document is opened. Newer versions have "Protected View" mode that prevents automatic execution of macro commands. Instead, users are asked to enable editing/content (i.e., macros) and warned of the potential threats.

How to avoid installation of malware?

To avoid infecting the device via spam mail, it is advised against opening dubious and 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 distributed through untrustworthy download channels (e.g., unofficial and free file-hosting sites, Peer-to-Peer sharing networks, and other third-party downloaders), illegal activation ("cracking") tools, and fake updates. Therefore, it is important to only use official and verified download sources. Additionally, all programs must be activated and updated with tools/functions provided by legitimate developers. It is crucial to have a reputable anti-virus/anti-spyware suite installed and updated. This software has to be used to perform 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.

manual malware removal step 5Check the list provided by the Autoruns application and locate the malware file that you want to eliminate.

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.
