Users who have anti-virus programs installed on their computer would be prevented from opening the file, as the anti-virus would block it. This is why having anti-virus software installed is so important.

How to recognize a malicious email

Malicious actors behind this malicious email are pretending to be a legitimate company Duncan Engineering Limited in order to pressure the receiver into opening the attachment. This is a common tactic used by almost all malicious parties that do such malspam campaigns. It’s not uncommon for scammers to pretend to be from companies like Amazon, eBay, etc. They also often claim to be from government organizations, banks, etc. It’s quite strange that this particular malspam campaign involves scammers pretending to be from Duncan Engineering Limited, as it’s not exactly a company the majority of receivers will have anything to do with. Users would be much more likely to open an attachment if the sender was someone they recognize or whose services they have used before.

If users pay close attention and inspect emails before opening their attachments, they should be able to avoid opening something malicious. One of the first things users should check is the sender’s email address. If users don’t recognize it, they should use a search engine to look into it, check whether it actually belongs to whomever the sender claims to be.

The second sign that helps determine whether an email is legitimate is how the receiver is addressed. This DUNCAN ENGINEERING LIMITED ORDER malspam email addresses the receiver as “Dear Sir/Madam”, which is a very generic greeting often used by spammers. If a company has legitimate business with the receiver, they would address them by name, not a generic Sir/Madam, Customer, Member, etc.

Perhaps one of the most obvious signs of a potentially malicious email is grammar and spelling mistakes. This DUNCAN ENGINEERING LIMITED ORDER malspam email has plenty of noticeable grammar mistakes, which would look highly unprofessional if this were a legitimate email. Since it’s not legitimate, it’s just another sign that an email is better left alone.

Even when everything checks out, it’s a good idea to scan all unsolicited email attachments with anti-virus or at least VirusTotal before opening them. VirusTotal would show if any anti-virus programs detect the file as malicious. For example, VirusTotal shows that the file attached to this DUNCAN ENGINEERING LIMITED ORDER malspam is detected by 17 of 56 anti-virus programs.

DUNCAN ENGINEERING LIMITED ORDER malspam is carrying Agent Tesla

If users were to open the file attached to this email, they would infect their computer with Agent Tesla, which is a remote access trojan, whose primary function is to steal sensitive information from the infected computer. In addition, it may log keystrokes and steal login credentials, which would allow malicious actors to gain access to various accounts. If those accounts do not have additional protection, someone gaining access to them could have serious consequences.

The malware would be immediately detected by anti-virus software but if users don’t have such a program installed, the malware may be able to hide its presence for a long time.


If users have not opened the attachment, they don’t need to do anything besides deleting the email from the inbox. However, if the file was opened, users would need to scan their computers with anti-malware software to delete the malware.
