207900 2004-01-16 07:42:00 Dad's shown me December's jetstream bill... and it's not pretty. 20GB or something, coming to a mere....... $4000!

I don't know what happened. Usually usage is around 1.5-2.5 GB per month, which I thought was pretty heavy usage. What sort of thing could use up this sort of bandwidth? I haven't downloaded 20 divx movies or anything, which is about the only thing that I can think of that could use up so much. Haven't done any online gaming. I’m fairly sure that I’ve disabled uploads on Kazaa, but I’ll have to check. I somehow doubt my sister downloaded several gigabytes of songs.

The other not so nice possibility is that we've been hacked... yes, we've got no software firewall, I thought that our Nokia router would do the job, but that doesn't stop trojans. :( Norton Antivirus is installed on both computers, however, so that discredits that theory a bit, I guess.

Dad asked for daily usage, and Telecom have emailed an unhelpful excel spreadsheet coupled with an equally unhelpful message saying that they "suggest we find the cause of this high usage.” Thanks for the tip.

The spreadsheet shows not a daily usage, but "periods of high activity" according to their email. It seems that 20.7 GB (!) was transferred from 24/11 2:43 – 6/12 16:11. That’s as detailed as the spreadsheet is. :( I find it a bit odd the internet would be used at 2:43 AM, but I doubt that’ll be enough to convince Telecom.

Help.:(

207901 2004-01-16 08:07:00 Bugger... looks like you are going to have to take the hit and pay the bill... on the other hand, do you have a wireless network in the house? Have you checked your PC for spyware, etc?

207902 2004-01-16 08:14:00 Imagine if you'd got the Blaster Worm.. How much data transfer might that have used.. Your router would have blocked a lot of traffic though... :-)

It'd pay to goto Windows Update and check through their 1,2,3 steps to a secure PC...

Dont forget to run Spybot Search and Destroy though :-)

But as Lo. said, there's not a lot you can do but foot the bill...

Installing a software firewall would definately help locate the cause!

BTW - In my first month I did 27gb on Jetstream starter.. I did 17 the month after and after 16 days for this month Im on 7 gigs...

Just thought you'd like to know that there are people out there who think that 2 1/5 gigs is next to nothing ;-)

Cheers

207903 2004-01-16 08:33:00 could be a virus/trojan/worm etc so virus scan etc, run all the usual checks. Set up a firewall as well (www.zonealarm.com is good) to check out if any dodgy ports are being scanned etc.

I think though, that you will find it difficult getting out of this bill, unless its telecom's fault it'll be you footing the bill :(

207904 2004-01-16 08:39:00 what speed is your connection? ilikelinux (1418)
207905 2004-01-16 08:53:00 Man that hurts!

I think you've got all the answers to make sure it doesn't happen again - get a firewall, disable uploads in Kazaa, up-to-date virus scan. Why not shut the machine down overnight too.

207906 2004-01-16 09:02:00 Windows on both PCs is fully patched. All ports closed (passed ShieldsUp @ grc.com with 100%). Scanning for viruses and spyware at the moment. I should mention that this is 20GB downstream traffic, so it can't be Kazaa or any other file sharing proggies. Sadly, our crappy router doesn't seem to provide dsl usage statistics, if it does, it's hidden amongst a lot of technical jargon. A decent DSL router would have been useful. :(
I should also mention that the hard drives of our computers are 20GB and 40GB respectivly and wherever that 20GB went, it doesn't seem to be on either of the computers. Not that I'd know where to look.

Looking at event logs won't work I think, as our broadband is the 'always on' type, and our main computer is on 24/7 because the power button is broken and it's a nightmare to start.

We DO have a wireless network, however. And I know that our neighbour also has a wireless network. But considering he helped us secure it in the first place, I doubt it's him. I could always go and interrogate him however. :ninja:

207907 2004-01-16 09:11:00 Can you obtain from somewhere a list of IP addresses that your computer allegedly connected to . Forgive me if I have my head in the sand here but with Jetstream starter many isp's can provide details of what sites and how much was downloaded off them .

Full Jetstream may be have a different way of showing this though as, I understand, Telecom handle all this themselves rather than your ISP .

Looks from what you have received so far that Telecom are not too interested in providing specifics, however seeing as you have surely now turned into one of their high value priority customers you may be within your rights to ask for proof of activity before paying .

The wireless network leak would seem, given your limited hard drive sizes and no evidence of extra files, to be a likely cause . Do a date range search on the drives . Look for * . * files created on the day(s) in question .

Silly question time: Were your PC's on at the time? Can you try turning them off but leave the network on and ask Telecom to monitor traffic over a few nights?

207908 2004-01-16 09:11:00 I think I'm lucky with my ISP - I get very accurate usage stats (Orcon) Greg S (201)
207909 2004-01-16 09:38:00 How did your neighbour "help" you secure your wireless network? Who's to say he didn't? And if he did then he would have been able to write down the keys to access your wireless lan.

OTOH, if he's smart enough to help you secure your network, he's also smart enough to help you determine how much traffic went through the wireless lan.
