What is "KNAPP EQUIPMENT Email Virus"?

KNAPP EQUIPMENT is the name of a spam campaign (scam) that cyber criminals use to spread the Agent Tesla malicious software. To achieve it, they send emails that include an executable file which, if opened, downloads and installs the aforementioned malware. As a rule, emails of this type are disguised as official and important. However, they should never be trusted and files attached to them opened.

KNAPP EQUIPMENT Email Virus

Scammer behind this email disguises himself as Victoria Mckenzie from KNAPP EQUIPMENT CO.,LTD. Recipients are asked to check availability of some product that can be viewed by opening the attached file as soon as possible. As we mentioned in our introduction, the attachment is an executable file that is designed to install Agent Tesla, a remote access tool which allows to access computers remotely. It is a legitimate tool, however, cyber criminals often use programs of this type for malicious purposes. Agent Tesla includes a keylogging feature which allows users (in this case cyber criminals) to record keystrokes. In other words, to record data entered (typed) with a keyboard. This feature can help cyber criminals to steal logins, passwords used to access banking, email, and other accounts. Having such information stolen can lead to serious privacy issues and financial loss. Stolen accounts could be used to extract money from other people too. For example, victim's account could be used to borrow money from people, trick them into making banking transactions or even into installing the same software which would allow cyber criminals to infect even more computers/spread Agent Tesla further. If there is any reason to believe that Agent Tesla is installed on a computer (and it was not done on purpose), it should be removed immediately.

As a rule, spam campaigns can be used to infect computers/spread malware in only one way - through attached files. Attached files usually are Microsoft Office or PDF documents, executable files (like .exe), JavaScript files, archive files like ZIP, RAR, and so on. They cannot do any damage if recipients do not open them.
