Cell Phone Shutdown Angers Afghans

Taliban attacks on telecom towers have prompted cell phone companies to shut down service across southern Afghanistan, angering a quarter million customers who have no other telephones, reports the Associated Press.

"Even some Taliban fighters now regret the disruptions and are demanding that service be restored by the companies.

The communication blackout follows a campaign by the Taliban, which said the U.S. and NATO were using the fighters' cell phone signals to track them at night and launch pinpoint attacks.

About 10 towers have been attacked since the warning late last month — seven of them seriously — causing almost $2 million in damage, the telecom ministry said. Afghanistan's four major mobile phone companies began cutting service across the south soon after.

The speed with which the companies acted shows how little influence the government has in remote areas and how just a few attacks can cripple a basic service and a booming, profitable industry. The shutdown could also stifle international investment in the country during a time of rising violence."

Talibans win. Operators shut down networks after 5pm

Mobile phone operators in Afghanistan have begun to switch off their networks during the night following threats from the Taliban, reports the BBC.

"Ten mobile phone masts were attacked in recent weeks, the latest on Tuesday night, the Afghan government says.

Last month the Taleban threatened the companies, alleging that the networks were being used by Afghan and Nato troops to target them.

... Since a threat by the Taleban last month to target the towers unless the phone companies switched off their signals at night, 10 such facilities have been attacked, six of them completely destroyed."

Warning to recipients of Zawahri Message

Saudi Arabia said yesterday nyone who received a voice recording from Al Qaeda’s deputy leader Ayman al-Zawahri on their mobile phone must inform the authorities within a week to avoid arrest.

The interior ministry said last week that 56 men held since December on suspicion of seeking to revive Al Qaeda cells in Saudi Arabia had planned to use a voice recording of Zawahri saved on a mobile phone to raise funds for the group.

Taliban blow up 4th telecom Tower

Taliban militants blew up another telecom tower in southern Afghanistan — the fourth such attack since the insurgents warned phone companies to shut down the towers at night. USA Today reports. No one was hurt in the incident.

"The militants believe U.S. and other foreign troops are using mobile phone signals to track insurgents and launch attacks against them.

But in targeting mobile networks, writes the IWPR, the Taleban may be losing one of their most precious assets – the tacit support of the local population.

While villagers in Helmand may turn a blind eye to public executions and grudgingly let their beards grow as the fundamentalists demand, they are extremely unhappy at the prospect of losing their phone service, for many their one link with the outside world."

Taliban blow up Afghan phone tower

Taliban militants blew up a telecommunications tower Friday in southern Afghanistan following a threat to phone companies warning them to shut down the towers at night or face attack. The AP reports.

"The militants fear U.S. and other foreign troops are using mobile phone signals to track insurgents and launch attacks against them. A Taliban spokesman on Monday said militants would blow up towers across Afghanistan if the companies did not switch off their signals overnight.

Insurgents made good on that threat Friday, destroying a tower along the main highway in the Zhari district.

Thousands of customers will be affected by the tower attack, Serhadi said. Police have increased security around other phone towers, he said.

Militants have threatened mobile phone companies in the past, accusing them of collusion with the U.S. and other foreign military forces.t of Kandahar province, said Niaz Mohammad Serhadi, the top district official.

Militants have threatened mobile phone companies in the past, accusing them of collusion with the U.S. and other foreign military forces.

Communications experts say the U.S. military has the ability, using satellites and other means, to pick up cell phone signals without the phone company's help. Cell phones periodically send signals to the network even when they are not making calls.

Taliban highlights militants' mobile tracking fear

A Taliban threat to attack Afghan telecoms companies is the latest sign of paranoia from militants who fear their mobile phones will betray their hiding places. Reuters reports.

"The Islamist militia on Monday gave mobile operators a three-day ultimatum to shut down their networks at night or face attacks on their towers and offices.

It issued the demand because "the occupying forces stationed in Afghanistan usually at night use mobile phones for espionage to track down the mujahideen," a Taliban spokesman told Reuters.

The threat comes several months after publication on the Internet of a "security encyclopedia" for militant Islamists which urges strict precautions when using mobiles. It even recommends a particular handset model it says is hard for the enemy to open to implant a bugging device.

Howard Melamed, chief executive of U.S.-based cellular communications group CellAntenna, said the Taliban threat reflected a lack of understanding of the technology.

"Common sense would dictate: turn your phone off and it's OK," he told Reuters. "I have a feeling they're not really in tune too much with this kind of technology."

Analysts believe that senior leaders of al Qaeda do not use either mobile or satellite phones at all in order to avoid detection, instead relying on people to carry messages by word of mouth."

Taliban Threaten Phone Companies

"Taliban spokesman Zabiullah Mujaheed said the U.S. and other foreign troops in the country are using mobile phone signals to track down the insurgents and launch attacks against them.

The Taliban have "decided to give a three-day deadline to all mobile phone companies to stop their signals from 5 p.m. to 3 a.m. in order to stop the enemies from getting intelligence through mobile phones and to stop Taliban and civilian casualties," Mujaheed told The Associated Press by telephone from an undisclosed location.

"If those companies do not stop their signal within three days, the Taliban will target their towers and their offices," he said.

There are four mobile phone operators in Afghanistan, but employees at the companies would not immediately comment."

Taliban tapping into British cell phones

According to UPI, British soldiers in Afghanistan have been barred from using cell phones because the Taliban have been tapping into them and making prank calls to their families.

This follows news last week that Denmark's military intelligence agency is investigating whether Iraqi insurgents have used mobile phone records to track down and threaten relatives of Danish soldiers deployed in Iraq.

"Intelligence officials fear that the Taliban may be picking up more than the information needed to frighten wives and parents, The Sun, a British newspaper, reported.

In one case, the wife of an air force officer got a middle-of-the-night call that said her husband had been killed, The Sun reported. When she called the Royal Air Force, she learned that was not true.

“You’ll never see your husband alive -- we have just killed him,” she had been told.

Soldiers must now call home only from secure military lines and are limited to 30 minutes on the phone each week.

Intelligence agents said that much of the tapping is being done in Pakistan and said that the Taliban may be getting."

Danes investigate Iraq phone threats

Denmark's military intelligence agency is investigating whether Iraqi insurgents have used mobile phone records to track down and threaten relatives of Danish soldiers deployed in Iraq, officials said Thursday, reports the Contra Costa Times.

"Family members of several soldiers have told Danish media that they received threatening phone calls from unidentified callers in Iraq.

The Iraqi callers may have tracked down the numbers by monitoring private phone calls made by the soldiers to their relatives in Denmark, according to the Danish Defense Intelligence Service.

"Right now, we're mapping the extent (of the threats), after which we will consider whether our guidelines to our staff and their families regarding the use of cell phones and e-mails should be revised," agency spokeswoman Mette Noehr said. "To our knowledge, we're talking about a limited number of cases."

Noehr said the agency was not sure whether insurgents were behind the calls.

"It could also be hoodlums but one thing is sure, we're taking this very seriously," she said."

Bush Wants Terrorism Law Update

President Bush wants Congress to modernize a law that governs how intelligence agencies monitor the communications of suspected terrorists. The Associated Press reports.

"This law is badly out of date," Bush said Saturday in his weekly radio address.

Bush noted that terrorists now use disposable cell phones and the Internet to communicate, recruit operatives and plan attacks; such tools were not available when FISA passed nearly 30 years ago. He also cited a recently released intelligence estimate that concluded al-Qaida is using its growing strength in the Middle East to plot attacks on U.S. soil.

"Our intelligence community warns that under the current statute, we are missing a significant amount of foreign intelligence that we should be collecting to protect our country," Bush said. "Congress needs to act immediately to pass this bill, so that our national security professionals can close intelligence gaps and provide critical warning time for our country."

... Caroline Fredrickson, director of the Washington legislative office of the American Civil Liberties Union, contends the White House is asking for more power to conduct warrantless domestic and international surveillance.

The ACLU said the legislation backed by the administration would give immunity from criminal prosecution and civil liability for the telecommunication companies that participate in the NSA program. The ACLU urged lawmakers to find out the full extent of current intelligence gathering under FISA before making changes.

"The only thing more outrageous than the administration's call for even more unfettered power is a Congress that would consider giving it to them," Frederickson said.

Terrorist suspects should be banned from using cell phones

Terrorist suspects should be banned from using cell phones - A quote by Wolfgang Schauble, Germany's interior minister in UPI.

"Schauble renewed his calls for preemptive laws after the recent attempted terrorist attacks in Britain. He is promoting legislation to allow suspects' computers to be monitored without their knowledge and for increased video surveillance in public places. Terrorist suspects also should be banned from using cell phones, he said."

Mobile phones 'crucial' in terror arrests

The Telegraph details how cell phones were instrumental in tracking down the terrorists in the London and Glasgow attacks.

"Police recovered phones from the two Mercedes cars which had been left in the centre of London. They are thought to have been left in the vehicles as detonators for the bombs.

This could have been done by setting the phone’s alarm or by ringing the handset from some distance away.

But for the phone to work it had to have a Sim card – the small chip provided by the phone company to the subscriber. It carries a wealth of information, such as whether it is on a pay-as-you-go contract or monthly subscription.

It also carries the phone number, enabling police to get details of calls made from the carrier.

It is believed that this could have helped police identify the address in Glasgow, which was raided just ahead of the attack on the city’s airport.

But the role of the mobile phone does not stop at identifying suspects, the signals they send also enabled police to track their movements as they passed the nationwide network of masts.

This network is so extensive that it is being considered as a potential option for a national road pricing scheme, because it makes it possible to track the movements of a car remarkably precisely."

Introducing the Cell Phone Bomb

Wired recalls the first mention of a mobile phone used as a bomb.

1996: The Israeli secret service found that a mobile phone makes a nifty little bomb for disposing of an enemy, which is what happened to Yahya Ayyash on Jan. 5, 1996 when he tried talking on a booby-trapped phone apparently provided by Israel's Shabak.

Ayyash was the chief bomb-maker for Hamas, and was linked to the killings of more than 70 Israelis, many of them civilians.

Israel has never confirmed or denied involvement in Ayyash's killing, but even the cheapest cell phone won't usually explode without a little help.

Al Qaeda’s novel death technique: Detonating hundreds of simultaneous explosions through cell phone and Internet

According to Debkafile, counter-terror sources report extreme concern among security services in the United States, Europe, the Far East and Israel, after the source of 350 multiple attacks in Bangladesh on Aug. 17, 2005, was traced to Tripoli, Lebanon.

"French counter-terror experts leading an international inquiry into the attacks discovered that a facility, set up there by Abu Musab al Zarqawi, al Qaeda’s late Iraq commander, had developed the new design which works through Internet messengers like Skype or MSN.

Network-connected mobile phones can remotely detonate over the Internet simultaneous explosions hundreds of miles apart, anywhere on the world. US forces located and killed Zarqawi on June 7, 2006.

This system, seen only in Bangladesh so far, is more complex than any used by al Qaeda before.

.. The materials found at the al Qaeda lab there were removed to forensic facilities in Paris and produced the following picture:

For its Bangladesh operation, al Qaeda had prepared 350 cell phones. Communications software was installed in each, together with a simple interface program designed in the Tripoli lab. Loaded onto the master computer in Tripoli linked to global Internet was the readily available Skype or MSN software. The cell phones were given 350 different usernames – or rather the same one with a different numeral, e.g. Tom1, Tom2, and so forth up to Tom350. The program was relayed to the mobile phones which then transmitted the operational signal to detonate the explosives.

The Bangladesh method would be hard to apply in the United States, Europe or Israel. Anti-terror security measures are more stringent there and would make it difficult to plant 350 hidden bombs without some being detected."

Mobile phones pose new security threat in Kashmir

As mobile telephones proliferate in Jammu and Kashmir, security agencies in the state are concerned over the threat they could pose - including as triggers for deadly explosions, informs M&C News.

Intelligence agencies have information that terrorist groups could use mobile phones to cause improvised explosive device blasts through remote control. Such explosions, experts say, can be carried out with greater accuracy due to dual-tone multi frequency technology used in these telephones.

Mobile phones can also be used as time bombs as they have facilities for setting time.

'Apart from cell phone guns, mobile phone cameras can be used for spying by taking photos of sensitive areas and, worse, a mobile can be used for tapping conversations,' a security official pointed out. Besides, he added, "it is difficult to differentiate a mobile phone from a mobile phone pistol. With some modification, some keys on the pad can be used as triggers for firing 0.22 calibre shots'.

Intelligence officials are working on mobile phones' use for tapping conversation. 'These (mobiles) can be used for eavesdropping as well. For this, only a small change in the chip is required. It can be activated by making a call to the mobile while it is receiving a call and the conversation can be overheard,' the official revealed. They are also working on 'fool-proof anti-sabotage checks' against the misuse of mobiles.

Cell network shut down hurts Mumbai victims

Troops in Kashmir master new weapon: cell phones

An interesting article from Reuters, rounding up examples of how cell phone tracking has helped some intelligence officers capture militants, and how others, prefer to use satellite phones.

... "Indian intelligence officers say troops have eliminated many militants by tracking their mobile phones and tapping conservations.

After three years, there are now more than 850,000 mobile phone users in a state of 10 million people. And the spin-off for anti-insurgency operations has enthused security officials.

"So far, we have arrested or eliminated dozens of them (militants) including many senior commanders through mobile-tracking," the intelligence officer said. "It is easier to track them if they use mobile phones."

Elsewhere across some trouble spots around South Asia, mobile phone services are still seen as a bane.

In Sri Lanka, which is teetering on the brink of a return to civil war, Tamil Tiger rebels do not allow mobile phone services in areas held by them.

"We do not allow mobile telephones because of security concerns," said rebel media coordinator Daya Master. The Tigers fear they could be tracked and targeted through mobile signals. So they use satellite phones instead.

... Police in Kashmir say mobile phones have also saved the lives of hundreds of people trapped in buildings stormed by suicide attackers.

"Hostages have often communicated with the police through mobiles and managed to guide security forces to rescue them amid gunfire", said K. Rajindra Kumar, a top police officer. "This is the success story of mobile phones in anti-militancy operations," Kumar told Reuters.

Police in hot pursuit of Delhi serial bom

New Delhi police were sifting through mobile telephone call records on Monday in their hunt for those behind the deadly blasts at New Delhi’s markets and investigating claims by a little-known Islamic militant group that it staged the carnage.

Phone calls may have triggered suicide bombs

Mobile phone calls from three accomplices might have triggered the explosives carried by three suicide bombers in Saturday's Bali terror attacks, according to The Sydney Morning Herald.

"Police are scrutinising an amateur video tape of a man apparently with a backpack entering a restaurant before one of three blasts which killed as many as 26 people and wounded 122.

Police say a likely scenario was that three suicide bombers walked into the three targeted restaurants.

Three accomplices stationed nearby then called mobile phones rigged to explosives carried in by the bombers.

The calls would have instantly triggered the bombs, said Indonesian anti-terror official Major General Ansyaad Mbai, who added that the three accomplices might still be on Bali.

.. Hospital officials have said the wounded included 64 Indonesians, 20 Australians, seven South Koreans, four Americans, three Japanese, one French, and one German, with other nationalities unknown".

Handsets' Deadly Use: Detonators

More and more terrorists are using cell phones to remotely detonate bombs — and there's not much authorities can do about it. At least, not that they can say, reports Investor's Business Daily, in a very interesting and thorough article on this issue.

"Cell phones have been connected to terrorist bombings in Madrid, Bali and Israel. Many roadside bombs in Iraq are believed to be triggered by cell phones. (more examples in Cell Phones used by terrorists)

... The very factors that make cell phones so easy and affordable to use also make them easy to use as detonation devices. Radio jamming gear can prevent cell phone detonations, but cops don't have easy access to such gear or the ready authority to use it. Carriers, too, are limited in what they can do to stop cell phones from being used to detonate bombs.

It's a complex, delicate situation. Few in government or industry care to talk about it publicly.

Unfortunately, it's easy to use cell phones as detonators. Handsets are so similar, terrorists encounter the same circuitry in most any phone. Phones can easily be disassembled.

"It takes about a minute and a half using a screwdriver" to connect a cell phone to a bomb, said Howard Melamed, president of Coral Springs, Fla.-based CellAntenna. It sells gear to jam cell phone signals.

Melamed says there are two main ways to use a cell phone as a detonator. One method is to connect a bomb to the wires of the phone's ringer. The bomb can be exploded with a call to the phone.

The other way is to connect a bomb to the phone's internal alarm clock, to detonate at a preset time.

Walls concedes that design makes it easy to convert cell phones into detonators. But cell phones can't shoulder all the blame, he says. Many other electronic devices use radio airwaves and also can be made into detonators. Authorities believe garage door openers, cordless phones and toy remote controls have been used as detonators of roadside bombs in Iraq.

Electronic jammers could prevent detonations. If a bomb is known to be in an area, the jammer interferes with signals reaching the phone, hence preventing ignition.

In July, the Pentagon began issuing the third generation of its Warlock electronic jammers to soldiers in Iraq. The latest version is handheld. Other versions are vehicle-mounted or require manpower.

Israeli security's had ready access to cell phone jamming gear because of that nation's long history of terrorist attacks, but not so elsewhere.

... jammers are fine in places like Iraq where the U.S. military has full authority to stop all cell phone communications in a battle zone. But in the U.S., jamming signals knock out all communications, even those of civilians. Oelrich says few government agencies want to risk the wrath of angry consumers who can't make a cell phone call.

More than that, the fact is that jamming devices work only when a bomb is detonated through calling a cell phone. A preset explosion using the cell phone's clock can't be prevented through jamming, since no signal goes over the airwaves.

... cellular networks also can be designed to allow only outgoing calls in certain locations, such as subway tunnels. That way, terrorists couldn't call a cell phone to set off a bomb."

Phone-bomb hijack

Cellphones provide a simple yet effective way for terrorists to remotely trigger a bomb. But now a portable device devised by US defence contractor Raytheon could quickly identify and disable such weapons, reports New Scientist.

"The device includes a transmitter that mimics a cellphone base station and a metal horn to concentrate the signal from a 10 milliwatt power source in a single direction. Scanning suspicious luggage with the tool tricks a concealed phone into thinking it is in range of a new network base station and blocks it from any genuine stations in the vicinity.

The suspect phone will also respond with a “handshake signal” containing its phone number, allowing a network operator to temporarily disconnect it from the real network, and preventing it from receiving a detonation call.

If the suspect phone turns out to be innocent, the worst that happens is that the phone needs re-connection.

London bombs made of ordinary stuff

Associated Press reports that the suicide bombers cooked up their explosives using mundane items like hydrogen peroxide. They stored them in a fancy commercial refrigerator that was out of place in their grimy apartment. And cell phones were probably used to set off the bombs. Investigators believe the three bombs that exploded in the subway were detonated by cell phones that had alarms set to 8:50 a.m.

"Those details from the July 7 London bombing emerged Wednesday at an unusually wide- ranging briefing given by the New York Police Department to city business leaders.

The briefing - based partly on information obtained by NYPD detectives who were dispatched to London to monitor the investigation - was part of a program designed to encourage more vigilance by private security at large hotels, Wall Street firms, storage facilities and other companies."
