DeathRing: Non-removable Pre-installed Malware@Androids

The smart-phones penetration in our country and for that matter any country has been seeing explosion like never before...from cheap mobiles with luring specs to high end smart-phones by Apple,Samsung,Sony etc.The growing and already a subject matter of concern in IT ie SECURITY is majoring as a serious threat in the mobile world too...like the Microsoft b70 case few years back(click here for details)....As evidenced by the latest pre-loaded malware identified called DeathRing that’s  a Chinese Trojan that is pre-installed on a number of smart-phones most popular in Asian and African countries.

as evidenced by the latest pre-loaded malware Lookout identified called DeathRing.

Charge cell phones by using Radio-Waves

1. Here comes another first from NOKIA...no more charging from your mobile chargers...no more that last minute search to find that hidden mobile charger....now charge from a mixture of 78.03% nitrogen, 20.99% oxygen, 0.94% argon, 0.03% carbon dioxide, 0.01% hydrogen, 0.00123% Neon, 0.0004% helium, 0.00005% krypton, 0.000006% xenon or more simply AIR!!!!!!

2. Nokia says that in a few years time, they will be able to charge cell phones by utilizing close radio waves. This conniving and shaking up technology could lead to brobdingnagian reductions in energy demand if every cell phone could pull a charge of juice out of thin air.

3. Researchers at the Nokia Research Centre in Cambridge in the UK are working hard on a technology that can harvest small amounts of energy from ambient radio and TV waves. The cell phone would pick up radio wave frequencies as low as 500 megahertz up to 10 gigahertz, which includes television broadcasts, microwave ovens, mobile phones, wireless LAN, bluetooth, GPS, and two-way radios. In theory, two circuits would be capable of receiving and then converting the free energy to an electrical current to charge the battery of a cell phone.

4. Hopefully, it would be enough energy to keep the phone charged in standby mode; although at first it won’t be adequate to charge the phone while in use, or to full battery capacity. So far, the device can collect up to 5 milliwatts of power, and the short term goal is to collect 20 milliwatts of power, which is just enough to keep the phone charged in standby mode. Ultimately, 50 milliwatts of power would be ideal and could help slowly recharge the battery.

5. This technology could be applied to other electronic equipment as well. Radio waves could be used to charge MP3 players, handheld devices, Kindles, portable game players, etc. Nokia isn’t relying on this type of technology alone to power their phones, they are also looking at integrated solar cells to work in conjunction with this new development. Deployment of this feature in Nokia phones is still at least 3 years away. We’ll be standing by with our waning cell phones waiting for word.

RADIATION EFFECTS & UR MOBILE - QUANTIFIED

1. We all hear about how the radiations emitted from our mobiles keep effecting us on the wrong side……but what are the specifications laid down for quantification of these effecting variables? What are these variables ?How much do they effect us? Do separate mobile handsets effect us in different ways?Are their any safe limits in these? What are the available standards?

2. The first and the most significant variable is the Specific absorption rate (SAR) , a measure of the rate at which energy is absorbed by the body when exposed to a radio frequency (RF) electromagnetic field. It is defined as the power absorbed per mass of tissue and has units of watts per kilogram. SAR is usually averaged either over the whole body, or over a small sample volume (typically 1 g or 10 g of tissue). The value cited is then the maximum level measured in the body part studied over the stated volume or mass.

3. SAR is used to measure exposure to fields between 100 kHz and 10 GHz. It is commonly used to measure power absorbed from mobile phones and during MRI scans. Few specifications of good and bad mobiles as found rated from TOI site at their INFOTECH tab are shown below with details :

SAMSUNG IMPRESSION : GOOD

Maximum radiation: 0.35 Watts per kilogram (W/kg) (based on reported radiation level when held up to your ear)

SAR when held at the ear: 0.35 W/kg

SAR when worn on the body: 0.83 W/kg

MOTOROLA RAZR V8 : GOOD

Maximum radiation: 0.36 W/kg

SAR when held at the ear: 0.36 W/kg

SAR when worn on the body: 0.86 W/kg

SAMSUNG SGH-T229 : GOOD

Maximum radiation: 0.38 W/kg

SAR when held at the ear: 0.38 W/kg

SAR when worn on the body: 0.69 W/kg

MOTOROLA MOTO VU204 : WORST

Maximum radiation: 1.55 W/kg

SAR when held at the ear: 1.55 W/kg

SAR when worn on the body: 0.58 W/kg

BLACKBERRY CURVE 8330 : WORST

Maximum radiation: 1.54 W/kg

SAR when held at the ear 1.54 W/kg

SAR when worn on the body 0.99 W/kg

4. United States: The FCC requires that phones sold have a SAR level at or below 1.6 watts per kilogram (W/kg) taken over a volume of 10 gram of tissue while European Union specify SAR limits within 2 Watts/kg taken over a volume of 10 gram

5. So next times some one asks you or even mentions about radiation effect of mobiles on health….just make the aspect more clear of weather of not his/her mobiles in meeting the S.A.R norms or not?

Chinese Mobile - Death or Life :The answer is finally LIFE

1. While doing a course in Sec'bad many of my colleagues purchased cheap but high in functions chinese brand mobile phones.There were few reactions in form of a anticipatory ban in few months from date of purchase since they do not have IMEI (International Mobile Equipment Identity) numbers and posed a serious security risk. ......but those who chose to buy it were ready  for the risk.....then finally the news came out in media that with effect from Apr 15 09 this year about 16 million handsets would go  out of service , as GSM service providers, including Airtel and Vodafone pull the plug on them. 

2. The verdict is finally out.The government has given a go-ahead to GSM operators to provide a new unique identification number to over 16 million China-made mobile phones in the country. Users of these handsets, which don’t have the 15-digit International Mobile Equipment Identity (IMEI) number, will have to shell out about Rs 180 to obtain the number. This has been made possible with the help of a new software, developed by GSM operators’ body Cellular Operators Association of India (COAI) and Mobile Standards Alliance of India.The association has obtained the IMEI numbers from GSMA, the global body that allocates these numbers.
