Banning Pre-Paid Cell Phones

June 7, 2010 terrorism No Comments

Former Libertarian Party presidential nominee Bob Barr notes that Faisal Shahzad’s Times Square bombing attempt might be a causus belli for the federal government to make pre-paid cell phones illegal. Excerpt:

bob barrThis innocuous device, available now to virtually anyone wishing to buy a cheap cell phone useable for a limited period, represents perhaps the last opportunity for a person to communicate anonymously.  Yet, these devices are being targeted for extinction by a pair of United States Senators simply because the failed Times Square bomber used one in his preparatory activities; and law enforcement discovered this not because the *purchase* of the cell phone was recorded in an accessible database, but because Shahzad made at least one call to a number already on a government list of suspected terrorists.

Democratic New York Sen. Chuck Schumer now has teamed with his Republican colleague from Texas, John Cornyn, and introduced a bill that would employ the heavy hand of federal law to prohibit anonymous cell phones. [...] [I]t is certain that many of their colleagues will jump at this latest chance to prove they are as tough on terrorists as the next guy, whatever the cost to the rest of the citizenry.

While Sens. Schumer and Cornyn may believe that the only people who purchase prepaid cell phones are terrorists, the fact is, many average, law-abiding citizens use such devices regularly.  Some people do so because they may not have the funds or the creditworthiness to buy a cell phone with a network plan.  Others may do so precisely because of the anonymity such phones offer; something especially important for journalists to be able to protect communications with their sources from being revealed.

Cell Phones Blamed for Honey Bee Decline

June 5, 2010 biology, disaster No Comments

Their disappearance has caused alarm throughout Europe and North America where campaigners have blamed agricultural pesticides, climate change and the advent of genetically modified crops for what is now known as ‘colony collapse disorder.’ Britain has seen a 15 per cent decline in its bee population in the last two years and shrinking numbers has led to a rise in thefts of hives.

bee collecting pollenNow researchers from Chandigarh’s Punjab University claim they have found the cause which could be the first step in reversing the decline: They have established that radiation from mobile telephones is a key factor in the phenomenon and say that it probably interfering with the bee’s navigation senses.

They set up a controlled experiment in Punjab earlier this year comparing the behavior and productivity of bees in two hives – one fitted with two mobile telephones which were powered on for two fifteen minute sessions per day for three months. The other had dummy models installed.

After three months the researchers recorded a dramatic decline in the size of the hive fitted with the mobile phone, a significant reduction in the number of eggs laid by the queen bee. The bees also stopped producing honey.

The queen bee in the “mobile” hive produced fewer than half of those created by her counterpart in the normal hive.

They also found a dramatic decline in the number of worker bees returning to the hive after collecting pollen. Because of this the amount of nectar produced in the hive also shrank.

Ved Prakash Sharma and Neelima Kumar, the authors of the report in the journal Current Science, wrote: “Increase in the usage of electronic gadgets has led to electro-pollution of the environment. Honeybee behavior and biology has been affected by electro-smog since these insects have magnetite in their bodies which helps them in navigation.

“There are reports of sudden disappearance of bee populations from honeybee colonies. The reason is still not clear. We have compared the performance of honeybees in cellphone radiation exposed and unexposed colonies.

“A significant decline in colony strength and in the egg laying rate of the queen was observed. The behavior of exposed foragers was negatively influenced by the exposure, there was neither honey nor pollen in the colony at the end of the experiment.”

Tim Lovett, of the British Beekeepers Association, said that hives have been successful in London where there was high mobile phone use.

“Previous work in this area has indicated this [mobile phone use] is not a real factor,” he said. “If new data comes along we will look at it.”

He said: “At the moment we think is more likely to be a combination of factors including disease, pesticides and habitat loss.”

The UK Government has set aside £10 million for research into the decline of pollinators like bees, but the BBKA claim much more money is needed for research into the problem, including studies on pesticides, disease and new technology like mobile phones.

According to the University of Durham, England’s bees are vanishing faster than anywhere else in Europe, with more than half of hives

dying out over the last 20 years.

The most recent statistics from last winter show that the decline in honey bees in Britain is slowing, with just one in six hives lost.

This is still above the natural rate of ten per cent losses, but a vast improvement on previous years.

There has been an increase in the number of thefts of hives across the world and in Germany beekeepers have started fitting GPS tracking devices to their hives.

Is Your Cell Phone Tapped

June 23, 2009 privacy 1 Comment

Careful your cell phone may be eavesdropping. Thanks to recent developments in “spy phone” software, a do-it-yourself spook can now wirelessly transfer a wiretapping program to any mobile phone. The programs are inexpensive, and the transfer requires no special skill. The would-be spy needs to get his hands on your phone to press keys authorizing the download, but it takes just a few minutes—about the time needed to download a ringtone.

This new generation of -user-friendly spy-phone software has become widely available in the last year—and it confers stunning powers. The latest programs can silently turn on handset microphones even when no call is being made, allowing a spy to listen to voices in a room halfway around the world. Targets are none the wiser: neither call logs nor phone bills show records of the secretly transmitted data.

More than 200 companies sell spy-phone software online, at prices as low as $50 (a few programs cost more than $300). Vendors are loath to release sales figures. But some experts—private investigators and consultants in counter-wiretapping, computer-security software and telecommunications market research—claim that a surprising number of people carry a mobile that has been compromised, usually by a spouse, lover, parent or co-worker. Many employees, experts say, hope to discover a supervisor’s dishonest dealings and tip off the top boss anonymously. Max Maiellaro, head of Agata Christie Investigation, a private-investigation firm in Milan, estimates that 3 percent of mobiles in France and Germany are tapped, and about 5 percent or so in Greece, Italy, Romania and Spain. James Atkinson, a spy-phone expert at Granite Island Group, a security consultancy in Gloucester, Massachusetts, puts the number of tapped phones in the U.S. at 3 percent. (These approximations do not take into account government wiretapping.) Even if these numbers are inflated, clearly many otherwise law-abiding citizens are willing to break wiretapping laws.

Spyware thrives on iPhones, BlackBerrys and other smart phones because they have ample processing power. In the United States, the spread of GSM networks, which are more vulnerable than older technologies, has also enlarged the pool of potential victims. Spyware being developed for law-enforcement agencies will accompany a text message and automatically install itself in the victim’s phone when the message is opened, according to an Italian developer who declined to be identified. One worry is that the software will find its way into the hands of criminals.

The current predicament is partly the result of decisions by Apple, Microsoft and Research In Motion (producer of the BlackBerry) to open their phones to outside application-software developers, which created the opening for spyware. Antivirus and security programs developed for computers require too much processing power, even for smart phones. Although security programs are available for phones, by and large users haven’t given the threat much thought. If the spying keeps spreading, that may change soon.

Security Researchers Claim To Hack GSM Cell Calls

May 20, 2008 Security 2 Comments

The creators of the in-development technology say they’ll be able to crack GSM encryption with only about $1,000 worth of equipment.

Security researchers presenting recently at the Black Hat D.C. conference in Washington, D.C., demonstrated technology in development that they say will be able to greatly decrease the time and money required to decrypt, and therefore snoop on, phone and text message conversations taking place on GSM networks.

Many mobile operators worldwide use GSM networks, including T-Mobile and AT&T in the United States. The 64-bit encryption method used by GSM, known as A5/1, was first cracked in theory about 10 years ago, and researchers David Hulton and Steve, who declined to give his last name, said today that expensive equipment to help people crack the encryption has been available online for about 5 years.

Until now, however, it’s been prohibitively expensive for people to get their hands on this technology. If it works, the technology Hulton and Steve are developing should be able to crack GSM encryption in less than 30 minutes with about $1,000 worth of equipment, or in about 30 seconds with $100,000 worth of equipment. The technology could potentially be helpful to law enforcement investigators, but could also be taken advantage of by malicious hackers. Hulton says he plans to commercialize the more expensive version of the technology.

Other hardware Hulton and Steve referenced uses two different techniques to snoop on GSM calls and can cost between $70,000 and $1 million. So-called “active” systems simulate a GSM base station and don’t rely on encryption because they trick phones into connecting to the GSM network through them. Other, so-called “passive” systems snoop on the traffic and are far more expensive.

Hutton and Steve’s technology relies on the use of an array of devices known as field programmable gate arrays to first create a table of all the possible encryption keys — in this case 288 quadrillion — and then decrypt each of those over the course of three months. The resulting tables of keys could then be used by software to decrypt GSM communications, which first have to be intercepted using a receiver that can listen in on GSM frequencies.

During their talk, Hulton and Steve also discussed the vulnerabilities of mobile device SIM cards, noting that GSM networks broadcast SIM cards’ unique IDs in unencrypted text, which can tell attackers or law enforcement what kind of phone someone is using. The GSM network also can tell snoopers how far a phone is from a base station, within 200 meters of error. They noted that SIM cards run Java Virtual Machines that operators have access to, and suggested that it could be possible for malicious attackers to install applications on user’s phones without them ever knowing, potentially rerouting traffic to a third party who listens in to phone conversations.

The GSM Association, a trade group representing more than 700 GSM operators, said it could not comment on the specific claims Hulton and Steve are making. However, spokesman David Pringle said in an e-mailed statement that while researchers have showed how A5/1 could be compromised in theory, none of their academic papers have led to “practical attack capability that can be used on live, commercial GSM networks.” He also noted that more advanced encryption is beginning to be deployed for GSM networks and that other networks, including 3G networks, don’t use A5/1.

Cell Phone IED Revisited

March 29, 2008 Military, Security No Comments

Cell Phone IED Almost anything that blows up can be turned into an IED, from grenades to plastic explosives to leftover mines. The most everyday of electronics — a cell phone, a garage door opener, a child’s remote-control toy — can be recast as a trigger. And the hiding places for the handmade bombs are everywhere: in the ground, aboard a truck, even inside an animal carcass.

So far, the strongest push to silence the bombs has come from the Army, which has ordered thousands of radio-frequency jammers from Simi Valley, California, firm EDO Communications & Countermeasures. The devices, called Warlock Green and Warlock Red, intercept “the signal sent from a remote location to the IED instructing it to detonate,” an Army official told military newsletter Inside Defense. The signal “cannot make contact, therefore when it can’t make contact it doesn’t detonate,” he added. “(It’s like) the cell phone never gets through, but (enemy forces) think it goes through.”

The Army won’t say much about the machines. But last week, service chiefs signed a contract with EDO for an additional 1,440 Warlock jammers, to be delivered in May at a cost of more than $56 million.
