Okay this one is not a "good" one, in terms of a good phishing email, because it
|
|
is obviosly a phishing email since I do not have the mentioned product bought at
|
|
mentioned company. But the fact that I get constantly emailed these made me finally
|
|
post this to the website.
|
|
|
|
I get them mostly in a pair of two, one to my main domain and one to a subdomain (which
|
|
includes the term `noreply` as part of the domainname).
|
|
|
|
## The mail body
|

|
|
{{< alert >}}
|
|
Watch out for the link, as you might see, it gets rendered to a `netcup.de` domain
|
|
as HTML, but the source code does look quite a bit different!

I'm sorry, this is either a very dumb person (or group) or it is a very funny coincidence.
|
|
I got two new mails today in which the **shown URL** was changed to
|
|
`www.customercontrolpanel.de`, the link still goes to the italian site (that you will find
|
|
further down in this article).
|
|
|
|
Following only the relevant part is shown.

Haha another two emails with yet another domainname: `netcupde.com`. Well, the link now
|
|
looks like this:
|
|
|
|
~~~html {linenos=table}
|
|
<p>Erneuern Sie über den sicheren Link:
|
|

|

|
_I added some newlines into the html code, because the code is actually only two lines
|
|
in the email but that would make this codeblock a bit harder to read (specially on mobile
|
|
devices)._
|
|
|
|
These additions of `<em style="...` are the reason for me not initially finding the domain `netcupde.com`
|
|
in that email as that would be the first thing that I'd look up in the email sources (see the end
|
|
of line 3 and up on line 4).

Another domain comes in quick. I doubt that everyone looks up a domains whois information, but if you
|
|
do, don't let them fool you. This one looks very valid, although it is not.
|
|
|
|
The new domain name I'm talking about is `netcup.eu` and it is also registered at `netcup.de`. The whois
|
|
information makes it look very related to each other...

I don't understand, why Netcup does not ban any domainnames on their
|
|
nameservers that include the term _netcup_ in their name.
|
|
|
|
By the way, the new link refers to `bodyplussize.pl`.

I guess I won't update this post much more, these emails seem to always show the same

boring text and structure.

## Why is this email invalid?
|
|
|
|
First of all, the sending host is not a Netcup GmbH server, it's hostname
|
|
is `v2202311112809242991.luckysrv.de`. This makes the mail suspicious, but the
|
|
main criteria why this email is no valid in no way: my domain `oe7drt.com` is
|
|
not managed at Netcup at all. There is just an A and AAAA (and others) record
|
|
that points to a root server at Netcup.
|
|
|
|
{{< alert >}}
|
|
**Update on Nov 18 2023**:
|
|
Oh, just because I updated the new URL they present you: they also send from a
|
|
new hostname: `v2202311110463243091.nicesrv.de` -- well, both domains are
|
|
saved on Netcup DNS servers which may indicate something ;-)
|
|
{{< /alert >}}
|
|
|
|
I thought I might share this one as well, because I get about 6-8 emails per day
|
|
about my "netcup domain". The fun thing is, one of the domain has a _noreply_ in
|
|
the domain name; I use this for several git repositories (like Github does). And
|
|
to eliminate any kind of misinterpretation: the domain includes **noreply** --
|
|
not **nodeliver**.
|
|
|
|
## Quite a few huh?
