There can be *many* Helmut Kohl's just as there are plenty of David
Thompsons, but you are probably correct since everything *else* about that
site was suspect already.

It's not obvious *what* the payload was, but from the URLs kindly provided,
it's obviously something that we should be suspicious of.

The main point though, was *where* to forward these payloads since the
exploits may time out in less than an hour - so we need to have the
forwarding addresses set up *ahead of time*.

Given that companies buy & sell iPhone zero-day exploits openly on the
market (e.g., Zerodium), the most recent set of three Apple zero-day
exploit SMS-link-sent attempts, for example, named "Trident", timed out
after only 1/2 hour, so, one would have to forward the SMishing message to
the "correct" authorities, within that time frame.
https://citizenlab.org/wp-content/uploads/2016/08/image16.png

Others exploits against that same phone expired after the first click, so
that security researchers themselves, had to be the first click - which is,
again, a reason to know, ahead of time, whom to send the links to, as
Mansoor did in the case of the three concurrent iOS zero-day exploits.

In that case, the person who received the message on his stock iPhone 6
running iOS 9.3.3., Mansoor, was prepared and sent it to a security
researcher at "Citizen Lab", who figured out the payload before it expired.
https://citizenlab.org/2016/08/million-dollar-dissident-iphone-zero-day-nso-group-uae/

That payload, which included *3* zero-day exploits, would have allowed the
attackers to remotely "jailbreak Mansoor's iPhone 6 and install spyware to
track his movements, record his WhatsApp and Viber calls, log his messages
and access his microphone and camera."
https://citizenlab.org/wp-content/uploads/2016/08/image10.png

Luckily, within a short period (less than two weeks), Apple patched the
three zero-day exploits in iOS 9.3.5, but many as-yet-unknown zero-day
exploits undoubtably exist in all operating systems.

1. CVE-2016-4657: Visiting a maliciously crafted website may lead to
arbitrary code execution
2. CVE-2016-4655: An application may be able to disclose kernel memory
3. CVE-2016-4656: An application may be able to execute arbitrary code with
kernel privileges

Looks like *both* sites are of suspicious nature (which is to be expected).

Unfortunately, we still don't know whom to *forward* the SMishing messages
to, so that they're looked at by security researchers before they are
clicked on once, or before they time out in 30 minutes...

I will be honest... I tend to just click what I want and then be careful
when I get there... but, yeah, seems there is a better way for me to deal
with it. :)

You can obviously see if anyone else 
has reported that url using google etc. 

And you can obviously use a completely secure 
system like a linux live cd to go to the url too.

Likely.

You should obviously be trying just the bit.do part, stupid.

Why do you ask the same question 3 fucking times ?

Submit the URL to virustotal.com -- they'll analyze it, and let you know. 

While you wait :-) . HTH.  Cheers, -- tlvp

Thank you tlvp for that *helpful* response!
http://virustotal.com

As we know from the latest series of four iOS zero-day exploits (three of 
which were concurrent), the URL must be submitted within a short time frame 
(as little as one half hour) of receipt, and, before it's ever clicked 
upon.

Therefore, this virustotal.com URL has to be saved, ahead of time, to be of 
any use, which I have done in an executable text-file shortcut on my 
desktop (which is trivial to create on Android).

Most of the score of site tests showed up clean when I pasted the URL just 
now into XXX but these two came up as "malicious":
AutoShun Malicious site
Dr.Web 	Malicious site

Web site category
Dr.Web
known infection source
Websense ThreatSeeker

Final URL after redirects

The number from which the message comes, can be faked.

You can't.

No.

Yes, I know. I've used those faked numbers myself.

One example is Spoofcard:
https://www.spoofcard.com/

Another example of a different way to fake it is, especially while on VPN:
Sideline – 2nd Phone Number by Pinger, Inc. 
https://play.google.com/store/apps/details?id=com.sideline.phone.number

Both are trivial to use by *anyone*, but I'm sure the SMishers have
*better* ways to hide the caller's real location than these two obvious and
free methods which I've personally tested out myself.

NOTE: SPoofcard offered a free test - I didn't check if they still offer
that, but I have done it in the past, and it *does* work - and is perfectly
legal in the USA (as long as the call purpose itself, isn't illegal).

BTW, if the URL in the suspicious SMS is from a known link shornener
company:

from command line:

curl -I <url>

This gives you just the headers which should have a 300 code and a
Location: header and you can then do whois etc on the actual location's
domain.

Up to this point, you have sent 0 info to the spammers since your only
transaction was to the URL shortening service.

There are services that expand shortened URLs.  <http://expandurl.net/>
and <http://urlex.org/> and <http://checkshorturl.com/> for example.

But that doesn't tell you what the actual site will try to do to you, so
if in doubt don't go there.

Thanks for providing those URLs which I have placed in a clickable text
file symbolic link on my desktop in my "communications" folder. 

The goal is to be *prepared* for the *next* similarly suspicious text,
which I get, perhaps once a month or so (sometimes a few times a week).

Normally I simply *delete* these texts, but I happened to have been on the
computer at the time I received that, so I figured I would just upload the
screenshot by bluetooth and post it while I was online.

I think there are three sets of actions that we can prepare ahead of time:

1. Forward immediately to an authority who can check it out further before
it times out. 
2. Expand the shortened URL to the actual link that it redirects to
3. Look up the provenance of the final link in a safe way (e.g., on a
pre-prepared Tails VM)

I think we've made headway on one of the three goals, but there's sill a
very long way to go for the other two.

On *that* topic, of "going there", it has to be pre-prepared.

The reason it has to be set up ahead of time is that the payload often
expires in a short time period (e.g., the latest simultaneous triplet of
iOS zero-day exploits were delivered by a link whose payload expired within
a half hour, and a previous iOS zero-day exploit expired after the first
click).

What do the OS people suggest as the best pre-preparation for visiting a
potential harmful link?

Would "Tails on a VM" be the best bet?

This site will expand the URL and show a snippet of text from the
destination page:

http://mopages.com/texis/browserinfo/longurl.html

Nice find!

That site not only expands teh URL redirect, but it also gives, as you
said, a text-only verson of the web page (which, we can presume, is "safe"
to read). 

That's almost perfect for figuring out *what* the suspect web page
ostensibly purports to do.

Thanks,
