Less Radiation

There was an interesting feature this week on BBC’s Watchdog programme about mobile phone text message spoofing. Two American researchers demonstrated how they are able to send fake MMS/Text messages that look like they’ve come from your bank to a smartphone.

This is a variation on phishing emails, but now on mobiles. All mobile network operators responded by saying that they weren’t aware of any real world use of this exploit that had so far left a single customer out of pocket – and they’re quite probably right. This seems like an awful lot of effort to go to if you want to get your hands on someones bank details & security passphrases.

I detailed on this site about 16 months ago that Dect cordless phones were now completely insecure. Anyone with a laptop, PCMCIA Com-On-Air Dect card & a decent antenna can record all you household phone calls from anywhere within a 200 metre radius of your home. Lots of older people now do home banking by telephone and over a series of calls you’ll be handing over full pins & security details. Even if you don’t give them to the bank you’ll be reusing them when you’re confirming your identity to insurance, utility & credit card providers – maybe you use that same 4 digit pin code for your home alarm & cashcard. Maybe you’re just paying for stuff with your credit card over the phone. If you live in a block of flats where tenants come and go every 6 months you’d be an easy target.

Ten years ago criminals could use an analogue radio scanner to record all the traffic on the old fashioned cordless home phones, perhaps to a computer for later analysis. They could use a DTFM decoder to figure out which number you’d called, and build up a profile that would leave them knowing you better than your best friend. Well now with the supposedly secure Dect phones they can take this further. Because each Dect phone has its own unique identifier – like the MAC address in your PC or the OUI number in a Bluetooth chip – it’s easy to zone out all the people you don’t want to listen to. Okay, only about half the Dect phones in use are insecure, but which half are you in? It’s not very reassuring is it? We’re nearly all using these Dect cordless phones at home these days.

Anyway, I saw not one article 16 months ago in the UK press or on TV about the Dect threat (although lots appeared in the German media), but now we need to worry about spoof texts. Go figure. If you really care about your health and security use a wired home phone.

As regards unusual text messages from your bank, apply some common sense – if it looks wrong, it’s because it is wrong. Wait until you get home and log onto your account there. Don’t ring numbers or use web links in these messages. Open a new browser window & check your balance from your 3G phone that way.

Pop into the bank and ask them about the real state of your account. If money diasappears from your account by a fraud that’s not your fault they’ll be giving you that money back anyway.

Smartphones are like mini PCs and they can get infected with malware and other nastiness, just like your home PC (for instance it’s now quite common for untrusting partners to secretly install tracking software on their partners smartphones to keep tabs on your whereabouts with GPS accuracy).

BBC Watchdog Story

Ryanair recently announced that they are fitting 14 of their 166 aircraft with mini cellphone masts.

The technology comes from On Air and tells each mobile to transmit at minimum power, to minimise any possible interference with the quite important in-flight electronics! Up to six passengers at a time will be able to use the system – any more presumably cause too much interference?

When the service starts only O2 & 3 networks will be compatible and the cost of calling will be a whopping £2 per minute or 40p for a text!

I’m so glad I don’t fly Ryanair.

Taken from an article by Lisa Adams of the Scottish Daily Record about Electrosensitivity – published 08/09/2008 :

IT’S called an allergy to modern life and half of Scots in the next 10 years could be at risk from this crippling illness, according to scientific research.

Victims of the condition, which is triggered by electromagnetic waves from mobile phones, power lines, microwaves and computers, suffer headaches, crushing chest pains, nose bleeds and a loss of feeling in arms and legs.

Experts report that up to 1.5million people in the UK already have their lives blighted by electro-sensitivity, with symptoms that also include heart palpitations, tiredness, fainting, light sensitivity and skin problems.

Mike Bell, chairman of the Radiation Research Trust, said: “We are seeing a significant increase in enquiries from individuals suffering from these symptoms.

“We’re concerned that many people could be living with health-related electro-sensitivity symptoms without realising the cause.

“Doctors in the UK are not trained to recognise this condition. They could be misdiagnosing patients and treating them with drugs rather than investigating the cause.”

One victim has compared the condition with life as a human aerial – their body overreacting to electrical waves in the environment. Today, as a scientific conference opens in London, public health expert Dr Gerd Oberfeld will predict that if current trends continue, up to 50 per cent of people could suffer from electro sensitivity symptoms in the next 10 years.

The World Health Organisation is also backing research, stating that: “Electrical hypersensitivity is a real and sometimes disabling condition.”

Sufferers are particularly vulnerable to the £2.5billion police communication system Tetra – Terrestrial Trunked Radio – which has been introduced throughout the UK. In the past three years, more than 1000 masts have been erected in Scotland. They pulse at 17.6hertz – above the 16Hz frequency the Government’s Independent Expert Group on Mobile Phones warns might affect brain activity.

Experts say radio waves at this frequency can cause calcium to leak from the brain, causing damage to the nervous and immune systems. If the masts are less than 15 metres high, they don’t need planning permission.

Former Norwegian Prime Minister Harlem Brundtland suffers from electro-sensitivity.

She said: “I felt a local warmth around my ear. But the agony got worse. It turned to discomfort and headaches every time I used a mobile phone.

“Some people develop sensitivity to electricity and radiation from equipment such as mobile phones or PCs.

“If this can lead to adverse health effects such as cancer or other diseases, we do not know yet. But I think we should follow the precautionary principle.”

Originally published in The Independent newspaper back in January 2008.

Using up all those free minutes before bedtime can seriously disrupt your sleep pattern. This is the conclusion of researchers in Sweden & the USA, in a properly controlled trial.

Critics from the mobile industry were quick to dismiss the effect as ‘no worse than having a coffee at bedtime’. But, up until very recently they insisted that no non-thermal effects existed with mobiles – now it seems that they’ve changed their tune…

Micro Mart magazine reports this week that OFCOM have given British airlines the go-ahead to install phone masts (picocells) on planes. The picocells will be switched off for take-off & landing, and will only be activated above 10,000 feet. The report states that BMI & Ryanair plan to install the technology soon. Great. Recycled air & electrosmog.
