Dear customers and business partners,

We have been receiving many hints from alert customers and contacts that they get spam and phishing emails from us. These emails do not come from WACHTEL, but are sent from spammer and so called botnets in our name.

If you receive an email whose content seems suspicious or has no direct relation to our business relationship, and especially if there is an attachment involved, please be cautious. Below you’ll find an example of a faked email as well as other helpful information.   What should I do if I receive an email like this? Delete the message, neither reply nor click a link or even open attachments. It is not necessary to inform us. We are aware of this situation, but unfortunately, can’t do anything about it

What if I´m not sure?

If you are not sure whether it´s a real message or not, please check the following points:

Email sender:
Our emails display first and second name, followed by the email address. If there comes another email address, more often a cryptical one, the sender is faked.

Example of a faked sender:

From: Oliver Frey <> []   Signature: In general, our email comes with a full signature, containing the WACHTEL Logo, the correct telephone number of the sender and the legal information of the company.

Personal address:

Our stuff normally greet you with your name. If there´s no personal address, but just an impersonal phrase in an email sent directly to you, you should be alerted.


Many spam emails refer to a supposed invoice. This can be easily identified as fake. Our invoice numbers begin with 24, 54 or 74 and contain no letters. As well as your client number which consists only of numbers and can be checked quickly.


How can I protect myself?

As already mentioned, don´t open attachments nor click links in suspicious emails and be especially cautious with attachments in general - also from known senders.

Effective anti-virus systems are capable to detect this kind of spam emails, direct them to the spam folder, delete the attachments or block the whole email (possibly informing you about the blocked email and the risky content). For private use, most of the email providers have good security standards detecting emails of this kind. For professional use, we recommend to inform your IT department if a spam email with attachment was delivered to your mailbox. A good cyber security software is the complement which can protect from these attacks if malware was accidentally activated.

It is recommended to invest in a good protection as virus attacks will be a constant danger in the future, likely becoming more and more wily and effective.


There are many internet portals with additional information about spam and phishing mails, e.g.:
