Avoid infecting your system with malware via fake "Olmetex" emails

Also Known As: Formbook virus
Type: Trojan
Damage level: Severe

What is "Olmetex email virus"?

"Olmetex email virus" refers to a malware-proliferating spam campaign - a large-scale operation during which thousands of deceptive/scam emails are sent.

The letters distributed through this campaign are disguised as purchase orders from Olmetex. This name belongs to a genuine company specializing in high-performance technical fabrics aimed at the fashion industry. It must be emphasized that these scam emails are in no way associated with Olmetex, and none of the information provided by them is true.

This spam campaign aims to infect recipients' devices with FormBook malware. The primary functionality of this malicious software is data theft.

"Olmetex" scam emails in detail

According to a rough translation from Italian, the fake "Olmetex" emails (subject/title "Ordinazione d'acquisto"; may vary) claim to have a purchase order attached to them. The letters request recipients to send an invoice for payment.

Once the "Lista degli ordini.exe" file (contained within a ZIP archive with the same filename) is opened - FormBook malware's infection chain (i.e., download/installation) is initiated.

FormBook malware functionalities

As mentioned in the introduction, the main feature of FormBook is stealing information. It can extract data from browsers and other installed applications. This malicious program also has keylogging abilities (i.e., recording keystrokes), and it can take screenshots.

Information of interest includes (but is not limited to): browsing activity, Internet cookies, account/platform log-in credentials (IDs, email addresses, usernames, and passwords), financial data (banking account details, credit card numbers, etc.), and personally identifiable information.

Other functions of FormBook include clearing Internet cookies, rebooting the system, shutting down the device, and so forth. Furthermore, this malicious program is capable of causing chain infections, i.e., it can download/install additional malware (e.g., ransomware, trojans, cryptocurrency miners, etc.).

To summarize, by trusting the "Olmetex" scam emails, users can experience multiple system infections, serious privacy issues, financial losses, and identity theft. If it is suspected or known that FormBook (or other malware) has already infected the system - an anti-virus must be used to eliminate it immediately.

Spam campaigns in general

"Santander Email Virus", "Contech Email Virus", "Contract Agreement", "Air Sea Land Email Virus", and "Pending Order" are some examples of malware-spreading spam campaigns.

The letters sent through these massive operations are usually presented as "official", "urgent", "important", and similar. They may mention the names of legitimate entities (e.g., companies, organizations, etc.), as is the case with the fake "Olmetex" scam emails. Alternatively, deceptive letters can closely mimic legitimate messages and contain genuine graphical details, contact information, etc.

Aside from distribution of malware, spam campaigns are also used for phishing and various other scams. Due to how widespread spam mail is, it is strongly advised to exercise caution with incoming emails.

How did "Olmetex email virus" infect my computer?

Systems are infected via malicious files proliferated through spam campaigns. These files can be attached to the scam emails, or the letters can contain download links of such content.

Virulent files can be in various formats, e.g., Microsoft Office and PDF documents, archives (ZIP, RAR, etc.), executables (.exe, .run, etc.), JavaScript, and so on. When the files are executed, run, or otherwise opened - the infection process is triggered.

For example, Microsoft Office documents infect systems 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 can manually enable macro commands (i.e., editing/content), and they are warned of the potential risks.

How to avoid installation of malware?

Suspicious and irrelevant emails must not be opened, especially any attachments or links present in them. It is also recommended to use Microsoft Office versions released after 2010.

However, malware is not spread exclusively via spam campaigns. Malicious programs are commonly distributed 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 fraudulent updates.

Therefore, it is advised to only download from official and verified sources. Additionally, all software products must be activated and updated with tools/functions provided by legitimate developers.

To ensure device integrity and user privacy, it is paramount to have a reputable anti-virus/anti-spyware suite installed and kept up-to-date. Furthermore, these programs have to be used to run regular system scans and to remove detected/potential threats. If you've already opened "Olmetex email virus" attachment, we recommend running a scan with Combo Cleaner Antivirus 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 Combo Cleaner Antivirus for Windows.
