I think you will find it is the smart ones who are concerned by the over-reaching mind set of NSA/GCHQ/etc.

The dumb one of which you speak are too busy watching Big Brother/TOWIE/Geordie-whatever to care about that is being done in their name.

So AC, you think that today's world is just like WWII when Hitler was crushing people across Europe and committing genocide on those groups he did not like?

If you feel so happy about mass surveillance and gov organisations that act as if they are beyond the reach of the law, why are you posting as AC? Fancy a bit of privacy, perhaps?

David Cameron wants mobe network roaming INSIDE the UK

Paul Crawford
Silver badge

Really?

"It introduces an incentive to “do a Netflix” and lobby regulators rather than invest in their own capacity and backhaul"

As if there is any incentive in these areas to invest in infrastructure anyway?

Lets face it, roaming works perfectly well for those on overseas SIM cards who do get to roam between UK network operators and they manage to deal with that OK. Same with banks using each other's ATM for customer service, they somehow manage to work out a financial compensation arrangement that makes it worth while.

I for one am 100% in favour of forcing this as the current status in sparsely populated areas is you are lucky to get any signal, let alone 3G, and it is not getting any better under the current business plans.

Sad

Not just MS of course, but the whole business model where you basically throw it all away in a few years once you find that repairing it is way too expensive even for parts like batteries that have finite known life.

Makes me wish that the EU or someone would introduce a legal requirement for a 5 year warranty so that suppliers had to up the game in terms of MTBF and/or make repairs a cost-effective options once more.

I'm personally willing to give up a few mm of thickness to gain that cost saving and landfill reduction.

Re: Liability

The point is not that someone did something stupid like not change the default password when prompted, it is when:

1) The user is not subject to any reasonable attempts to point this out to them, or

2) Said password can't be changed (looking at you Siemens' SCADA equipment), or

3) Software supplied is subject to a known flaw (e.g. Heartbleed) and they DO NOTHING to fix it.

All software has bugs, the issue is not that this will happen but that there will be lots of stuff that is simply not fixed because the manufacturers are too incompetent to do so, or just want to sell you another one.

If they were held liable for, say 5 years, after the product was on sale and for all bugs not fixed after a reasonable notification time (like the suggested 30 days), then maybe they would take it a bit more seriously. Of course it would cost a little more, but think of how much better we would all be if the race to the bottom on development, testing and support was halted in the name of security.

Re: Secret Tech

Also a lot of these tools need physical access to fit them to the victim's computer. Generally speaking, if the bad guys have breached your physical security then you don't have much chance anyway. Also that ups the ante quite a bit, as someone (even if a corrupt employee) is there doing the fitting and risking jail-time it caught by CCTV, observant staff, security checks, etc.

Google, Microsoft to add remote KILL switch to phones

Paul Crawford

Re: And what's the real subtext here...?

The networks are already able to block phones if they really want to. Even if they don't use the IMEI to block like they do in Europe, they can keep killing your subscriber account.

This just makes the phone more obviously blocked so it can't be as easily or profitable re-sold. Of course there will be ways round it, but make it too much trouble and eventually the druggies, etc, doing the robbing will realise its not such a pot of gold (or heroin) after all.

Top Canadian court: Cops need warrant to get names from ISPs

Paul Crawford

Re: No sympathy.

There are two separate issues that the court seem to rightly have asserted : firstly that IN GENERAL the police, or anyone else, needs a warrant for such private information. That is the whole point of judicial oversight. The second point you appear to have overlooked is the court also ruled that in spite of this point, the evidence in this case stands.

Overall this is a triumph of common sense.

Tech companies are raising their game (and pants) post-Snowden

Paul Crawford
Silver badge

"The goal here isn’t to keep the NSA out, because realistically they will find a way in if they really care about you. The goal is to raise the cost so that bulk surveillance becomes impossible."

Amen to that. We all knew spy organisation perform spying activities, but we thought/hoped it was targeted on the basis of probable cause and court oversight. By raising the cost of doing so, it becomes targeted again, court or no court.

The other aspect of this is likely to be a general improvement in security practice, something that also helps against access by foreign gov (for any given definition of "foreign" that fits) and criminal hackers.

Agreed, to be a boffin you need to meet several requirements:

1) To perform research in to something technical.

2) Said research is to create something new and special (i.e. not just a slightly cheaper/faster phone or similar). Physics/astronomy theory might just get in there, but only if well beyond normal comprehension.

3) Points 1 & 2 are more important to said boffin than "normal" social activities. Not to say they don't enjoy a pub, BBQ, or anything similar, but are quite likely to head back to test tube-bothering at unpredictable times.

Israel develops wireless-malware-injection-by-smartmobe tool

Paul Crawford

Re: This is quite credible

Er, no. A typical PC is pretty immune to mobile phone signals, otherwise it simply crashes. What you are thinking of is interference to the audio systems, but that counts for nothing really (bar spoiling your YouTube videos, etc).

As already stated, it is easy with lots of power to crash a PC but much harder, to the point of being virtually impossible, to crash selective sections. And the PC is already in a Faraday cage, called its box.

An attack based on bluetooth/wifi is much, much more likely as a large number of PCs have those enabled by default and mobile phones can communicate with them. Even if logically "off" it is quite likely that the protocol stack has vulnerabilities that can be exploited to access the PC.

Hell, I once managed to wipe the boot sector of an XP PC when developing a USB peripheral while using MS' own stack and drivers. So if it can be done there, I have no doubt it is at least theoretically possible with wifi/bluetooth if the hardware is on and listening, even if not supposedly used.

@knarf

Do you know anything about what you are talking about?

Buffer overruns and similar attacks (e.g. mal-formed pictures) require you to actually get the have the PC do something with the data that is subject to a lack of validation. That is simply not possible with a sound system bar, perhaps, voice-to-text-to-command conversion which is hardly likely.

Same for other routes, to actually inject data to a system that is not expecting it (wired network, USB cable, etc) needs a LOT of energy, not something that is going to go unnoticed and not something you will get from a mobile phone meters away.

First time I got an ESD test gun I did the obvious - ignored the instructions, wound it up to maximum (above 18kV) and tried it on my PC. It was fine, but I crashed an old (pre-EMC regulations) PC in the adjacent office.

To do so took a lot of peak power, and it is virtually impossible to induce such a crash in a controlled manner to exploit it. It is not like a buffer overrun where you can inject code in a specific place, you induce data/address corruption in a GHz clocked PC and you have no idea of just where it is going to bork at.

I see no feasible way of pushing malware on to an air-gapped computer. The sort of RF power needed to flip bits is simply going to crash it. Unless it has something like wi-fi or bluetooth operating of course!

Getting data off an already infected but now air-gapped computer is within the bounds of belief, but unless you are looking at very special hardware (i.e. not a mobile phone) then the data rate would be very low as it is not so easy to get most hardware to generate a wanted modulated signal that won't be drowned by the usual chatter of data and address bus activity of both the PC and the phone (along with the usual spread-spectrum clock typically used to help meet EMC requirements).

Re: you scratch my back and I'll spend tax payers money on you.

It depends on what you use Amazon for. If it is cloud backup then you never have to send the keys - just have the TrueCrypt volume on there, even with DropBox that works (diff sync only changes/ sends the blocks that are updated not the multi-GB file).

If its a VM running something then yes, it is fairly easy to grab the system memory while it is running.

If $SPYAGENCY with billion $CURRENCY budgets is willing to go as far as knobbling your OS via a targeted update (as opposed to a general 0-day vun or _NSAKEY style of arrangement) then you don't stand much chance anyway.

"How can anyone take open source seriously when major bits of software are managed by pouty children?"

Have you ever worked in a large company? The management layer can be every bit as bad, though for subtly different reasons.

In any case there are plenty of examples of closed source products that only ever got reluctantly patched once a breach had occurred, and not when they were notified of it. Should we not take commercial software seriously as a result?

Linux users at risk as ANOTHER critical GnuTLS bug found

Paul Crawford
Silver badge

Re: Buffer Overflow

It is possible, but often not done for historical or laziness reasons.

The most common problems are copying or printing a string of characters in to a destination that is too small, so it overflows into somewhere else that can then be exploited. The usual culprits in the C/C++ language are strcpy() and sprintf() (and similar) but you can often use alternatives such as strncpy() and snprintf() instead which take the destination size and enforce that limit (though with strncpy() you should also enforce nul-termination of the string as it won't do that).

If the destination buffer is allocated by the malloc() family, then in Linux you can also use the electricfence library for debugging and that puts each buffer in to a separate page and any violation results in a segmentation fault that you can then debug from the core dump. However, you would not normally use electricfence that for release code as it has a performance penalty, it is really intended for testing and debugging.

WTF?

Re: "who are shamelessly stealing from TrueCrypt"

You might want to look up what stealing means. It implies depriving the rightful owner of something of value.

Given that the moral owners of the TrueCrypt name are not coming forward, and that there is absolutely no sign of them commercialising this product in any way, I don't see what is being "lost" to justify a copyright infringement charge, let along "stealing".

Sure it is an infringement of the license terms, but who is actually suffering? Certainly not the end users who otherwise would have to go to something else that might be much worse in terms of privacy.

Samsung, Chipzilla in 4K monitor price cut pact

Paul Crawford

Re: Greg D

I find that I work at around 60cm from my monitor, so for a 24" HD monitor that is about 0.5mm per pixel. According to Wikipedia the limit of human eye resolution is about 0.21mm at that distance, so I would hardly call that "terrible" resolution.

However, I heartily agree with you that modern monitors are piss-poor and have worse capabilities than ~2002 CRT devices. So yes, 4k is welcome and long overdue, but I still would argue that most folk (OK, those of my age range) will not be working close enough with comfort to benefit so much from the "retina" style DPI.

Size matters...

...not ultra high DPI.

Few folk can work at distances from a monitor where the current DPI is terribly noticeable, certainly not for any length of time. Hence in my humble opinion the really useful market for 4k monitors in the 30" (or a bit more) where having in effect 4 x 15" HD monitors patched together is going to give you useful space for images, text, etc.

A great man

Such a shame he died young, but good to see some of his stuff is coming out from the metaphorical locked filing cabinet stuck in a disused lavatory with a sign on the door saying 'Beware of the Leopard'.

An example of his mind is in the El Reg article when he died in 2001:

"What we are now focussed on at h2g2 is what happens when people start to share information while they are on the move. Soon we will start to see devices arriving that combine palmtop computers with cellphones with Internet devices with GPS systems. That - in a phrase we hear over and over again when people talk about the Internet - will change everything. You'll be able to read and write to the Guide wherever you are: at the station, in the plane, on a park bench, in your car (pulled over to the side of the road with the handbrake on, of course) in a café. And when you write in something as simple as 'The coffee here is lousy!' the Guide will know exactly what to do with that information and where to put it. And if you see, a few seconds later, a note which says 'Yes, but the cheesecake is good' it might be worth looking round the other tables to see who you've just made contact with."

See, basically he invented the iPhone and Facebook!

Just a shame there were not actually invented by him and he had lived, I bet they would have been a whole lot less shitty to the end user's respect.

Re: king of foo

"But surely MS do something fundamentally wrong when it comes to security?"

It is more complex than that.

Modern versions of Windows can be locked down pretty good, but that requires a high level of skill and an attitude of not making life easy if it makes it vulnerable. Home users do not normally fall in to that category, and some (usually small) businesses are run by folk with little more IT knowledge.

What MS also has to battle is a legacy of folk just downloading and running stuff, often while logged in as admin, and just clicking "yes" to every annoying pop-up that asks them if shaftmesideways.exe should be allowed to do XYZ.

In that respect the typical *NIX system user is not expected to do that, and won't normally be logged in as root. Add to that the typical package manager approach to getting most software and it is a different mind-set, more like the Apple walled garden app store.
