BT Home Hub SIP backdoor blunder blamed for VoIP fraud

Re: Well watch out for 192.168.99.X

no need to hide private IP's on internet forums as they are non routable across the internet

http://en.wikipedia.org/wiki/Private_network

its the public addresses you need to worry about as they lead right to your network.

you are being far too paranoid. just 1 firewall properly configured that doesn't deliberately lie to you is sufficient to keep you safe, most will have a firewall on each computer too.

if you are this scared at the moment, just wait till ipv6 is rolled out, each machine will have its own publicly addressable ip, whilst right now you only have 1 publicly addressable IP for all your home devices.

Re: A few at fault here

if you pen tested the internet connection from the internet before the pbx was installed its likely the port in question would have been shown as not listening/down/nothing there just as you would expect if the firewall was configured to drop inbound traffic. Its an undocumented feature on the BT HH thats at fault. even if the pbx was installed and just happened to be offline at the time of a port scan it would have looked like the ports where locked as expected. The fix in this case would be, assuming the pbx runs on *nix, is to enable the firewall on the pbxs and permit only those ports from specific internet IP's.

Who would bother to test if the firewall was truly blocking for the specific ports in question? When you do the job for a while you expect to trust your equipment, basic or advanced, firewalls generally do as they are told.

3. It quickly emerged that the IP PBX had been set up on the same subnet as the computer network

FAIL - not only from a security perspective, but stupid from a networking perspective too. Again, if you want to do a botch-up job like this, you'd better know the implications of it.

even if they where on different subnets they would need some security (ACL or firewall) between the subnets to make any difference. just having multiple subnets is not enough, Also having the PBX on a different subnet to everything else may not have made any difference here.

using the supplied documentation, the administrator selected the settings that indicated all non solicited inbound connections would be dropped. The expectation driven by the available information was that all inbound non solicited comms would be dropped. If it said block all non solicited inbound apart from SIP then everyone would be clear that the sip port was vulnerable and take approprate action.

So as a home user i now need to pen test access to my (and those i care about) internal network from the internet as i can't trust the config settings on my ISP supplied router.

does anyone actually know anyone that thinks smart meters are a good idea?

As has already been mentioned once the novelty has worn off it won't stop people carrying on with their lives, watching tv, boiling the kettle, turning the tumble dryer on or whacking the thermostat up. It won't stop my other half leaving the sky box on when turning the tv off or leaving the tv on when turning the sky box off, won't stop the bathroom lights being left on all day and all night unless i switch them off or turning the oven on 2 hours before its needed. i need smart devices and appliances that can remind people to turn them off if not in use or better still just turn themselves off , not smart meters

Re: Your phone and your thumb!

@ Tim Brown 1

How very dramatic! the first of many to come. There are probably limits on how much money can be moved by the app and even if the phone and thumb where stolen the phone could be remotely bricked. I can't see this resulting in a spike of muggings involving amputation on the off chance the owner has installed and setup mobile banking by one of these banks that uses TouchID, the risk is not worth the reward (easy to trace the destination of the money increases the chances of being caught). Hundreds of millions of iPhones and a few hundred thousand app downloads.

Re: platitudes

BT have to provide a competitive service just as everyone else does. Open reach charge everyone the same including BT, SKY & Virgin. There is no conspiracy here. If Open Reach was independent everyone would be lobbying it to their advantage and it would be a complete mess, costs would go up and service down. despite ditching Marconi, 21CN seems to be successful and has enabled others to provide services on Open Reach at a competitive costs. gone are the days of paying £20 just for unto 8MB broadband.

Vodafone Pay TV launch rumoured for November

I wonder if VM's expansion plans are a reaction to Vodafone entering the TV market or just BT's push for market share? As VM have shown they have no interest in creating content they should let others provide services on their infrastructure and see the take up increase. Earning something from the homes their wires are installed in is better than nothing!!

Love or hate it but Sky are knocking out some great content. If byour a sports fan that is the only place in town but with stiff competition from BT.

I watch F1 and the core team that moved from ITV to BBC are now on Sky and producing great content both during and outside of the race weekend. This is at the expense of the BBC coverage which was excellent but now nowhere near as good but the Sky coverage is an improvement over what was excellent BBC coverage. Having written that if I didn't get F1 with my HD subscription I would not subscribe to sky sports just to get the once or twice a month F1 races that anyone wanting F1 now will have to do.

In my opinion Sky do in the large provide value for money if you enjoy watching their content.

@ Lee D

2TB is a lot to be carting about, is it important? is it backed up, what happens if the laptop is lost/stolen, what happens if the drive dies?

Surely you only use a hundred GB or so of that data at a time that could be easily cached on an affordable (<£150) SSD, the rest could be resiliently stored with fast remote access to it.

the concept of carting all your data around is outmoded. Fast networks and fast storage reduce the need to have all your stuff with you.

Re: Willy Waving

@Mage

i really don't understand why people complain about others pushing the current envelope. Bill Gates said you didn't need more than 640 KB, one of the richest men on the planet got it totally wrong and made his money of the back of proving he was wrong ever since.

I do think there is a limit as to how much of something is actually useful and how much is surplus, i.e the UK speed limit is 70 MPH but for technical reasons (need revs & gears) my car can do much more than that. If they designed it to do 70 MPH at the edge of its envelope it would be woeful at everything & I'd buy something more spritely.

in my eyes, there is a lot of fragmentation in how companies staff IT in the UK. In the past there where network, server, desktop, application & developer teams, many of the labour intensive roles like developer and application teams have been hived off as packets of work to third party companies, initially based in the UK but now more likely abroad. In my eyes this outsourcing is what is reducing the availability of UK based staff, and now many organisations require data to be retain in the eu/uk which requires staff here hence the need to import those foreign nationals doing the jobs abroad to do them here instead!!

Euro broadcast industry still in a fug over that 4K-ing UHD telly

chris 17

Re: Again?

1080i is less bandwidth than 720p which is why 1080i is used for HD.

1080i is 540 lines interlaced with the next frame so at 30 frames per second that is 30 frames at 540 lines each frame

720p is 720 lines each frame so at 30 frames per second that is 30 frames at 720 lines each frame.

i'm always amazed at how many people don't understand the difference between p & i.

1080p is the current gold standard and requires ~ twice the bandwidth of 1080i effectively 2 HD channels, the providers would rather eek out 2 paying HD channels than 1 for the same money.

incidentally in the UK SD is 576i which is 288 lines per frame, 1 HD channel at 1080i is ~ 2 SD channels, 1080p is ~3.75 SD channels.

Re: "Satellite is the ideal way to distribute 4K. We will drive it just as we did with HD"

Also 1080i is lower bandwidth than 720p, just 540 lines shown each frame vs 1080 with progressive.

i read many years ago it was the reduced bandwidth that the providers liked as they didn't need to rent so many frequencies from the satellite providers.

Traditional enterprise workloads on an all-flash array? WHY WOULD I BOTHER?

chris 17
Bronze badge

The reason that ERP system has an 80ms client side latency is because the query took 13 separate 6ms storage requests and 2ms of processing to answer. Turn those 6ms requests to 1ms and your latency drops to 15ms, turn them to 500us requests and the total latency drops to 6.5ms. This is without doing any modifications to the application, there is basically no better place to invest money in to optimize than storage performance.

totally agree!!

You only have to look at a typical webpage to see the huge number of requests going here there and everywhere to deliver the page content. Internal apps aren't far off especially the security conscious ones that have to retrieve secure keys from hardware security modules. this all adds to the latency experienced at the client, its not all a single simple san data retrieve.

Re: Budgets are binary

That's the same problem with budgets across the public sector, there is no onus or reward to save money, but you won't get in trouble spending more than you could have but within your budget. Also if you spend less now you'll get less next time and have to work harder to justify why you need more than last time to do x. Stupid blind accountancy.

Crapita strikes again. I've been avoiding working for them for the past 10 years, every business they buy they close and relocate the "service" elsewhere. Problem is you never know where they will strike next. I imagine for security reasons they need to keep onshore a lot of the government department jobs which is a good thing at least. There should be a limit to the amount of contracts (value or volume) one organisation can have across government, that would atleast promote competition between the players.

Virgin Media to splurge BEELLIONS on UK network infrastructure expansion

Re: Wholesale...

@ Ledswinger

its not the same concept. there are loads of people in VM's patch that are ADSl customers on poor speeds. i'd rather have sky broadband over VM's net than just VM. I'd guess there are a lot of customers like me and it would encourage greater usage of VM's infrastructure earning VM more money from it. OpenReach is earning for every ADSL line (line rental), VM could be earning too if they opened their net up for high speed BB to competitors. The issue is VM are earning too much from line rental that costs them sod all (they don't have the same network costs per line nut this may be regulated) & competitors would expect a healthy discount on that. VM are "cutting their nose to spite their face" on this.

The closest concept of VM allowing competitors on their net is like Virgin Mobile operating as an MVNO on O2's mobile phone network.

Re: Hmm

After WW2 Britain had a choice to repair or renew and chose to repair and maintain.

Germany had no choice and had to renew. Massive rebuilding projects ensured employment and investment in modern efficient machinery and practices. This propelled Germany into the industrial power house it is today and contributed to the downfall of British manufacturing as it couldn't compete due to its lack of investment (it was good enough before before etc)

What time do you call this, BT? Late, state-funded broadband rollout plods on

i'm closer to the exchange than our cabinet and get 17mbs on our fttc (the very limit of service availability) ads would be ~ 6mbs, whilst our last house i was getting ~22mbs on ADSL2 (same exchange different cab). having just got VM i'm now hoping FTTdp will be rolled out asap and save us from the crappy VM throttling. i'm in total agreement with the first poster, in that no one else wanted to put their money in and even if they did, they can't do the work any cheaper than BT can.

it would be great if i could get a different provider over VM's cable network, just like i can over OpenReach, Transco & National Grid.

Re: The whole point - encourage new businesses

~2004 the national organisation i was working for was paying £2.5k amortised per month per site for 256 -> 512 kbs atm leased lines across ~20 sites. Its expensive complicated stuff and costs. If you want the cheaper broadband but the isp has no capacity it'll cost them to add capacity which may not be economically viable for broadband but could be for a business leased line. I'm sure the company in question would take the same approach to any of their customers where the cost of doing the work would exceed the rate they could charge for it.

if you knew what you where talking about you'd understand why it took so long. i'd be pretty pissed if some telco yanked my fibre to give to you because of congestion. to uncongest they need to re route which requires planning and potential outages to customers that might not be in your geographic location but some where on the ring that services your cab/exchange. providing reliable comms is not as easy as just plugging a cable in, the reliability comes from careful methodical planning & despite the fashion for bashing BT, considering the traffic they transit for essentially all uk ISP's (yes even VM) the system on a whole is very reliable and resilient.

If these guys wanted faster internet access they should have ponied up for a proper business dedicated internet connection (MPLS over something service) instead of relying on a cheap as chips residential or small business broadband connection.

If you want a resilient connection go dual carrier with diverse routes. It costs a fortune, requires careful methodical planning & you'll need some skilled network engineers to ensure it runs smoothly all of which costs.

In the 80's it was possible to buy a key from a market that would open almost all fords, then there was the open with a half tennis ball trick. then there was the once in short the ignition system to start the car. Electronic security systems not only make it harder for a thief to open the door (they could and still can smash a window) they make it very difficult to start the car without the proper key, even the correct mechanical key won't start a modern (since at least 1994) vehicle with the correct immobiliser electronic signature.

Most cars with electronic keys have a mechanical key to open at least 1 door, this is at least true with her mini and my merc.

unless a car is being stolen for parts its very difficult to pass on stolen vehicles in the UK to unsuspecting purchasers. When the purchaser registers the car its VIN & Registration will be checked by DVLA, when its due an MOT the VIN will be checked by the garage. Customs should be checking number plates and VIN's on vehicles transiting UK borders, Yes a crook could use a valid number plate for a matching vehicle when leaving the UK, but UK spec cars aren't as desirable on the continent as the driver is on the wrong side. Also in Europe the vehicle VIN will identify the car as stolen when the new owner registers it for tax or road worthiness.
