Re: Tracking an IP Address

How serious is a crime would you say impersonating someone is, in order to frame them for doing something relatively illegal. Serious enough for deeper investigation?
You are too vague, but in principle: yes. Sounds like the other person has done something illegal, so the police will care. Covering it up by pretending to be somebody else makes it worse. Doing all of it to frame somebody makes it eve worse from there - because it shows a great deal of planning and therefore intent.

Something along the lines of calling direct to a business intelligence guy or a data analyst and say that his boss ok'ed it or something.
Yeah, right. Because telephone companies have never before got calls from people trying this. This is the worst piece of advice today so far, it will only get the OP in trouble.

I have worked in a Swiss telephone company before and have heard from our third level support that even a very senior manager did not get the info on his adult childs position when he pulled all the strings to find it out - they simply did their job and shut up without a warrant. They are Swiss after all.

Re: Tracking an IP Address

The Meta data might not even exist if they were using a Public WiFi router that does not store such details. Even then, the address could be spoofed. IP addresses are not reliable evidence, at best it traces back to the device and not to the user. Consider what use it would be if you involved in an accident and you took down number plate details that were forged.

You have to match the IP address to the actual user, and that is near impossible with shared equipment being all the norm.

Re: Tracking an IP Address

In principle, the only person who can know who was using that IP at a given moment with accuracy would be the ISP. Of course, the ISP is not going to reveal you this information unless they have good reasons for this (i.e. court asks for it).

Now, I don't know if what someone suggestes could be feasible. You could try to inquire what websites that IP was visiting at that time,... that could give you some traces.

Most phones will have private IP addresses so this will not work.

How about a change of tack...

Is there a register online that stores what websites various IPs are accessing? So say I had a date and time that the IP was accessing the email, could I also see what sites it accessed in the surrounding 20 mins say?
No, not a website, but the ISP's firewalls MIGHT have some sort of traffic accounting, but 99% of the time, if it is engaged, it's spent on the incoming, not the outgoing, traffic...and there's always the problem of privacy so, that would be an issue even if they did have the data you are looking for. Then there's always the joy of actually narrowing down the data you want as router accounting is a deluge of data. So..the short answer is, no.

There is one way to get a soft confirmation on the IP address ...as most dynamic IP assignments these days tend to be of a reasonably long duration, you can send an email to the person that you think they'll reply to. When you get the reply, enable the 'long headers' in your email client and buried in there will be the IP of origination (unless the ISP's SMTP strips it off). However, that information will only satisfy your curiosity, not be legally helpful.

Good luck with that as, yes, the civility on the internet is even more fragile than the civility in real life as at least in RL, there are standards of conduct that are enforceable by law. Online, not so much.

If he has a public IP address that would generally indicate that he was connected to a WiFi network somewhere. www.network-tools.com should tell you who the provider is and contact them about the alledged hacking as well as the police.

Re: Tracking an IP Address

Hmm...but there is a possibility to grab the browser's history (his) if you can set up a web page and get him to visit it. That would be a lot faster, easier and more complete than something from the ISP. Of course, again, this would be only usable by you.

Re: Tracking an IP Address

Have you asked the ISP?
It should be fairly trivial to pull out the information from their logs, if you are lucky someone will just give you the information and not care about the legal side.

Or he could have been using IP over 3G/UMTS... In which case the DHCP would have been through the ISP...

Also, if everything was done via a proxy or ghost service then you have to get the Proxy owner or other service owner to cough up the details of the source IP...These are usually based in another country and then everything becomes a lost cause.

ISP's do no generally maintain firewalls for customers, but for internal security. Any traffic most likely went through a switch.

Also, ISP's have blocks of IP addresses, and due to the nature of mobile and laptop usage (on and off the network frequently), most lease times are very short so the address can be re-used quickly, reducing the size of the pool of IPs the ISP has to maintain/block book.

Re: Tracking an IP Address

Lastly, the OP has to provide Police with sufficient evidence that an actual crime has taken place (A colleague surfing or downloading Porn on somebody else's PC may breach a company's policy, but it is not a crime). If there is no crime (i.e. a victim) then the Police will be reluctant to get involved and investigate further.

Re: Tracking an IP Address

If you intend to do this via the ISP/telecoms company you have 6 months in which to do it. They are only required to keep the logs of which customer's equipment had which IP address(es) at any specific point in time for that long.

Your friend should take the issue to the police, or start a civil action if they can't deal with it (since you don't say what you believe this person has done, nobody can tell you which is more appropriate, but your friend might want legal representation if he takes it to the police anyway).

Re: Tracking an IP Address

Just to emphasise, since the message seems to be getting lost in a lot of uninformed noise:

  • retrieving time-based IP device assignments and the related IMSI and destination IP addresses is a non-trivial activity, takes time and costs money
  • the service provider will not do this without police/court requesting this

Re: Tracking an IP Address

Go to www.ripe.net, put in the (external) IP, and contact the ISP or hosting provider. Usually they have a so called "abuse" contact address (e.g. abuse@cablecom.ch). That's all you can do, no technical possibility to track such personal info.

Re: Tracking an IP Address

Thanks Harrie, have been on that site, but not yet contacted the abuse hotline, I'd rather try and get some results than get a nice email stating thanks for your concern, we take online security very seriously, followed by, sorry, we cannot help you.

That does not seem to be true. As per Art. 174 (about Calumny)
http://www.admin.ch/ch/f/rs/311_0/a174.html

It seems if you have made raise any suspicion toward someone that would be against honor (like watching porn from work), you are guilty of that offense and liable up to 3 years jail or/and a fine.

Re: Tracking an IP Address

Ok, my friend is willing to release the IP and scenario.

His Gmail was hacked on April 3rd, and an email (whose content I shall not reveal, but suffice to say it is depraved) was sent from his account at 19:53 (Swiss Time).

The IP address which did this, was 194.230.155.12

Any help in identifying the culprit (and more importantly exonerating him) would be appreciated.

Thanks,
StirB

What suspicions have been raised in my example ? I simply stated watching porn from somebody else's PC, not trying to blame them for it.
