Criminals try to obtain confidential company data with the help of fraudulent emails, fake websites and other methods. By pretending to be a well-known person (colleague, boss) or organization (bank, service provider), the scammers exploit the victim’s trust to willingly disclose information.
The working day begins and you check your emails, then you discover an email from one of your service providers. The text talks about a bill whose amount surprises you. The invoice is attached as a document. You are surprised because you have not commissioned this service provider in the last few months. What you do in the next few seconds is crucial:
A) You treat this email with skepticism, because you are sure that no invoice was to be expected from this service provider. They take another close look at the email. Your service provider is indicated as the sender, but the e-mail address is conspicuous. For example, it is web@YSJ1QFWP8RU0C0N6.net or bricklayer316@moselland.de. Your suspicion deepens and you delete this e-mail. If you are unsure, give your service provider a quick call. Under no circumstances should you open the attachment of this e-mail unless you are completely sure that it really comes from your service provider.
B) You open the attachment of the email to find out more. Apparently nothing bad happens, but the invoice is obviously fake. You delete the email. But when you open the attachment, a virus has already been activated. While you’re busy with other things, he sends emails with false invoices to all your contacts on your behalf. If you’re unlucky, the virus will then load malware onto your computer, leading to failures or even blackmail .
Always treat email attachments and links with suspicion. Always check the sender’s email address for emails. Delete obvious fakes. But even if you have the slightest suspicion, ignore the e-mail at first and check it outside the e-mail program:
