An anonymous reader quotes the BBC: Ordinary wi-fi could be used to detect weapons and explosives in public places, according to a study led by the Rutgers University in New Jersey. Wireless signals can penetrate bags to measure the dimensions of metal objects or estimate the volume of liquids, researchers claim. Initial tests appeared to show that the system was at least 95% accurate.

It could provide a low-cost alternative to airport-style security, researchers said. The system works by analysing what happens when wireless signals penetrate and bounce off objects and materials.

Los Angeles officials announced Tuesday that the city's subway will become the first mass transit system in the U.S. to install body scanners that screen passengers for weapons and explosives. "The deployment of the portable scanners, which project waves to do full-body screenings of passengers walking through a station without slowing them down, will happen in the coming months, said Alex Wiggins, who runs the Los Angeles County Metropolitan Transportation Authority's law enforcement division," reports the Associated Press reports: The machines scan for metallic and non-metallic objects on a person's body, can detect suspicious items from 30 feet (9 meters) away and have the capability of scanning more than 2,000 passengers per hour. On Tuesday, Pekoske and other officials demonstrated the new machines, which are being purchased from Thruvision, which is headquartered in the United Kingdom. In addition to the Thruvision scanners, the agency is also planning to purchase other body scanners -- which resemble white television cameras on tripods -- that have the ability to move around and hone in on specific people and angles, Wiggins said. Signs will be posted at stations warning passengers they are subject to body scanner screening. The screening process is voluntary, Wiggins said, but customers who choose not be screened won't be able to ride on the subway.

According to American Airlines, the airline is working with the TSA to install a new bag-scanning machine at New York's John F. Kennedy International Airport. "The machine uses the same technology as CT scanners, providing a 3D image of bag's contents, and is expected to be operational in late July," reports The Verge. From the report: The new scanner, which will be used at the airport's Terminal 8 security checkpoint, will allow TSA to rotate a bag's image 360 degrees to show its contents. American Airlines says this should provide a more effective way for agents to inspect bags for explosives and other prohibited items. TSA administrator David Pekoske tells CBS News that the new machines could allow for liquids, gels, aerosols, and laptops to be left in bags. The TSA plans to have 15 of the new CT scanners at airports by the end of the year, and are authorized to purchase up to 240 of the machines, which cost $300,000 each, in 2019. The technology has also been tested at Phoenix Sky Harbor International Airport and in Boston.

A team of former FBI investigators is claiming to have proof of the real identity of D.B. Cooper, the notorious airplane hijacker who has remained at large since he parachuted out of a Seattle-bound plane with $200,000 in November 1971. From a report: According to filmmaker and author Thomas Colbert -- who has led the independent investigation into the cold case for the last seven years -- the real Cooper is a 74-year-old Vietnam veteran named Robert Rackstraw. And the proof is hidden in a series of letters allegedly written by Cooper in the months after the hijacking and his disappearance. Rackstraw -- a former Special Forces paratrooper, explosives expert and pilot with about 22 different aliases -- was once a person of interest in the case, but was eliminated as a suspect by the FBI in 1979. His elimination was controversial amongst the investigating agents, and he remained, for many, the most viable suspect in what remains the only unsolved case of air piracy in the United States. In 2016, the FBI announced they were ending their investigation into the case.

A Japanese spacecraft has arrived at its target - an asteroid shaped like a diamond or, according to some, a spinning top. From a report: Hayabusa 2 has been travelling toward the space rock Ryugu since launching from the Tanegashima spaceport in 2014. It is on a quest to study the object close-up and deliver rocks and soil from Ryugu to Earth. It will use explosives to propel a projectile into Ryugu, digging out a fresh sample from beneath the surface. Dr Makoto Yoshikawa, Hayabusa 2's mission manager, talked about the plan now that the spacecraft had arrived at its destination. "At first, we will study very carefully the surface features. Then we will select where to touch down. Touchdown means we get the surface material," he told me. A copper projectile, or "impactor" will separate from the spacecraft, floating down to the surface of the asteroid. Once Hayabusa 2 is safely out of the way, an explosive charge will detonate, driving the projectile into the surface.

New submitter cornholed writes: Yesterday, Reddit updated their Content Policy forbidding transactions for certain goods and services. From the formal announcement on Reddit: "As of today, users may not use Reddit to solicit or facilitate any transaction or gift involving certain goods and services, including: firearms, ammunition, or explosives; drugs, including alcohol and tobacco, or any controlled substances (except advertisements placed in accordance with our advertising policy); paid services involving physical sexual contact; stolen goods; personal information; falsified official documents or currency." Bloomberg has an interesting write-up on how Reddit is wading into the gun control debate. See this post on Reddit for a full-list of all subreddits banned. "Reddit has been something of a Wild West for users building communities by curating and commenting on content in subreddits," reports Bloomberg. "Sometimes, as in the case with gun sales, marketplaces emerge in the course of conversations within specific communities. With Reddit's increased popularity -- the site is the sixth-most-visited in the world -- has come introspection and stricter content guidelines. The company recognizes its responsibility for having provided a platform for hate groups to flourish and, more recently, the possibility that Russian propaganda on the site may have played a role in influencing the 2016 presidential election."

Long-time Slashdot reader hey! writes: Benjamin D. Morrison of Beaver Dam Wisconsin was killed on March 5 while synthesizing explosives in his apartment... The accident has left the apartment building so contaminated that it will be demolished in a controlled burn, and residents are not being allowed in to retrieve any of their belongings.
It was just five years ago that Morrison graduated from Pensacola Christian College in Florida with a degree in pre-pharmacy and minors in chemistry and math. Though a local reverend believes 28-year-old Morrison was "not a bomb maker," USA Today's site FDL Reporter notes that "Officials assume he was making bombs that accidentally exploded and killed him... They have not publicly disclosed what chemicals were in apartment 11 where Morrow lived, only describing them as 'extremely volatile and unstable explosives.'"

An anonymous reader shares a report: Amazon said on Wednesday that it was reviewing its website after a British television report said the online retail giant's algorithms were automatically suggesting bomb-making ingredients that were "Frequently bought together." The news is particularly timely in Britain, where the authorities are investigating a terrorist attack last week on London's Underground subway system. The attack involved a crude explosive in a bucket inside a plastic bag, and detonated on a train during the morning rush. The news report is the latest example of a technology company drawing criticism for an apparently faulty algorithm. Google and Facebook have come under fire for allowing advertisers to direct ads to users who searched for, or expressed interest in, racist sentiments and hate speech. Growing awareness of these automated systems has been accompanied by calls for tech firms to take more responsibility for the contents on their sites. Amazon customers buying products that were innocent enough on their own, like cooking ingredients, received "Frequently bought together" prompts for other items that would help them produce explosives, according to the Channel 4 News.

More than 70 years ago the UK's Royal Air Force dropped an 1,100-pound bomb on Germany. They just found it. An anonymous reader quotes ABC: Residents in two German cities are evacuating their homes as authorities prepare to dispose of World War II-era bombs found during construction work this week. About 21,000 people have been ordered to leave their homes and workplaces in the western city of Koblenz as a precaution before specialists attempt to defuse the 500-kilogram bomb on Saturday afternoon (local time). Among those moved to safety are prison inmates and hospital patients. Officials in the financial capital Frankfurt, meanwhile, are carrying out what is described as Germany's biggest evacuation. Frankfurt city officials have said more than 60,000 residents will have to leave their homes for at least 12 hours.

Failure to defuse the bomb could cause a big enough explosion to flatten a city block, a fire department official said. "This bomb has more than 1.4 tonnes of explosives," Frankfurt fire chief Reinhard Ries said. "It's not just fragments that are the problem, but also the pressure that it creates that would dismantle all the buildings in a 100-metre radius"... Police will ring every doorbell and use helicopters with heat-sensing cameras to make sure nobody is left behind before they start diffusing the bomb.
Reuters notes that every year Germany discovers more than 2,000 tons of live bombs and munitions, adding "In July, a kindergarten was evacuated after teachers discovered an unexploded World War Two bomb on a shelf among some toys."

The United States has ended a four-month ban on passengers carrying laptops onboard US-bound flights from certain airports in the Middle East and North Africa, bringing to an end one of the controversial travel restrictions imposed by President Donald Trump's administration. From a report: Riyadh's King Khalid international airport was the last of 10 airports to be exempted from the ban, the US department of homeland security (DHS) confirmed in a tweet late on Wednesday local time. Middle East carriers have blamed Trump's travel restrictions, which include banning citizens of some Muslim-majority countries from visiting the United States, for a downturn in demand on US routes. In March, the United States banned large electronics in cabins on flights from 10 airports in the Middle East and North Africa over concerns that explosives could be concealed in the devices taken onboard aircraft. The ban has been lifted on the nine airlines affected -- Emirates, Etihad Airways, Qatar Airways, Turkish Airlines, Saudi Arabian Airlines, Royal Jordanian , Kuwait Airways, EgyptAir and Royal Air Maroc -- which are the only carriers to fly direct to the US from the region. A ban on citizens of six Muslim-majority countries -- Iran, Libya, Somalia, Sudan, Syria, and Yemen, -- remains in place, though has been limited after several US court hearings challenged the restrictions.

An anonymous reader quotes a report from The Verge: The United States will require foreign airports to implement stricter security practices and screenings for any passengers headed to the U.S. John Kelly, the U.S. secretary of Homeland Security, announced today that the new measures were being put in place. Though he didn't go into specifics, Kelly said the new requirements would include further screenings of electronics, more thorough vetting of passengers, and measures meant to stop "insider attacks." The U.S. is also encouraging the use of more bomb-detecting dogs, "advanced checkpoint screening technology," and the addition of "preclearance" locations, which station U.S. customs officers overseas, allowing them to screen passengers before boarding instead of after they land. One thing Kelly didn't announce was an expansion of the tablet and laptop ban, which is currently in effect on flights from 10 airports in the Middle East and North Africa. If airports don't comply with the new screening rules, Kelly said, they may be subject to additional electronics bans. But for the time being, it sounds like the ban will be kept to those 10 locations. According to Reuters, airlines have 21 days to comply with the new rules for explosives screenings and four months to comply with everything else.

An anonymous reader quotes the New York Times: It has been more than a year since the Pentagon announced that it was opening a new line of combat against the Islamic State, directing Cyber Command, then six years old, to mount computer-network attacks... "In general, there was some sense of disappointment in the overall ability for cyberoperations to land a major blow against ISIS," or the Islamic State, said Joshua Geltzer, who was the senior director for counterterrorism at the National Security Council until March. "This is just much harder in practice than people think..."

Even one of the rare successes against the Islamic State belongs at least in part to Israel, which was America's partner in the attacks against Iran's nuclear facilities. Top Israeli cyberoperators penetrated a small cell of extremist bombmakers in Syria months ago, the officials said. That was how the United States learned that the terrorist group was working to make explosives that fooled airport X-ray machines and other screening by looking exactly like batteries for laptop computers... The information helped prompt a ban in March on large electronic devices in carry-on luggage on flights from 10 airports in eight Muslim-majority countries to the United States and Britain.
Citing military officials, the Times also reports that "locking Islamic State propaganda specialists out of their accounts -- or using the coordinates of their phones and computers to target them for a drone attack -- is now standard operating procedure."

An anonymous reader writes: US and EU officials have decided against a ban on laptops and tablets in cabin baggage on flights from Europe. But after a four-hour meeting in Brussels to discuss the threats to aviation security, officials said other measures were still being considered. US officials had previously said they were looking into extending to Europe a ban on electronics on flights from eight mostly Muslim countries. The measure was introduced over fears a bomb could be concealed in a device. The meeting was requested by EU officials after recent reports suggested US authorities had new information regarding laptop parts being turned into explosives.

An anonymous reader shares an article: The Department of Homeland Security will ban laptops in the cabins of all flights from Europe to the United States, European security officials told The Daily Beast. An official announcement is expected Thursday. Initially a ban on laptops and tablets was applied only to U.S.-bound flights from 10 airports in North Africa and the Middle East. The ban was based on U.S. fears that terrorists have found a way to convert laptops into bombs capable of bringing down an airplane. It is unclear if the European ban will also apply to tablets. DHS said in a statement to The Daily Beast: "No final decisions have been made on expanding the restriction on large electronic devices in aircraft cabins; however, it is under consideration. DHS continues to evaluate the threat environment and will make changes when necessary to keep air travelers safe."

The U.S. Navy announced today that it will no longer allow sailors to use electronic cigarettes on ships, following several reports of explosives and injuries. ABC News reports: Naval commanders said in a statement Friday that the temporary electronic cigarette policy aims to protect sailors and the fleet. It starts next month. Officials cited overheated batteries in vaping equipment as the problem. Explosions have led to fires, first-degree burns and facial disfigurement. During a recent eight-month stretch, 12 incidents put sailors out of work for a combined 77 days. Injuries also restricted some to light duty for a total of five months.

Last week, United States and United Kingdom officials announced new restrictions for airline passengers from eight Middle Eastern countries, forbidding passengers to carry electronics larger than a smartphone into an airplane cabin. Now The Guardian reports, citing a security source, the ban was prompted in part by a plot involving explosives hidden in a fake iPad. From the report: The security source said both bans were not the result of a single specific incident but a combination of factors. One of those, according to the source, was the discovery of a plot to bring down a plane with explosives hidden in a fake iPad that appeared as good as the real thing. Other details of the plot, such as the date, the country involved and the group behind it, remain secret. Discovery of the plot confirmed the fears of the intelligence agencies that Islamist groups had found a novel way to smuggle explosives into the cabin area in carry-on luggage after failed attempts with shoe bombs and explosives hidden in underwear. An explosion in a cabin (where a terrorist can position the explosive against a door or window) can have much more impact than one in the hold (where the terrorist has no control over the position of the explosive, which could be in the middle of luggage, away from the skin of the aircraft), given passengers and crew could be sucked out of any subsequent hole.

Norway is planning to build the world's first ship tunnel through the country's Stad peninsula, which is home to harsh weather conditions that often delay shipments and cause dangerous conditions for ship crews. The proposed tunnel would enable ships to travel through the peninsula in safety. New Atlas recently interviewed Stad Ship Tunnel Project Manager Terje Andreassen about the project: NA: We'd usually expect a canal to be built for this kind of purpose, so why a tunnel? Because in this case we are crossing a hill which is more than 300 meters (984 ft) high. The only alternative is a tunnel. From a maritime point of view this is still a canal, but with a "roof." NA: How would you go about making such a large tunnel -- would you use a boring machine, for example, or explosives? First we will drill horizontally and use explosives to take out the roof part of the tunnel. Then all bolts and anchors to secure the roof rock before applying shotcrete. The rest of the tunnel will be done in the same way as in open mining. Vertical drilling and blasting with explosives down to the level of 12 m (42 ft) below the sea level. NA: How much rock will be removed, and how will you go about removing it? There will be 3 billion cubic meters (over 105 billion cubic ft) of solid rock removed. All transportation from the tunnel area will be done by large barges. NA: What, if any, are the unique challenges to building a ship tunnel when compared with a road tunnel? The challenge is the height of this tunnel. There is 50 m (164 ft) from bottom to the roof, so all secure works and shotcrete must be done in several levels. The tunnel will be made dry down to the bottom. We solve this by leaving some rock unblasted in each end of the tunnel to prevent water flowing in.

Assuming it does indeed go ahead -- and with the Norwegian government having already set aside the money, this seems relatively likely -- the Stad Ship Tunnel will reach a length of 1.7 km (1.05 miles), and measure 37 m (121 ft) tall and 26.5 m (87 ft) wide. It's expected to cost NOK 2.3 billion (over US$272 million) to build and won't actually speed up travel times, but instead focuses on making the journey safer. Top-tier architecture and design firm Snohetta has designed the entrances, and the company's early plans include sculpted tunnel openings and adding LED lighting on the tunnel ceiling.

In addition to rifles, mortars, artillery and suicidal car bombs, ISIS has recently added commercial drones, converted into tiny bombs, into the mix of weapons it uses to fight in Iraq. In October, The New York Times reported that the Islamic State was using small consumer drones rigged with explosives to fight Kurdish forces in Iraq. Two Kurdish soldiers died dismantling a booby-trapped ISIS drone. Several months later and it appears the use of drones on the battlefield is becoming more prevalent. Popular Science reports: Previously, we've seen ISIS scratch-build drones, and as Iraqi Security Forces retook parts of Mosul, they discovered a vast infrastructure of workshops (complete with quality control) for building standardized munitions, weapons, and explosives. These drone bombers recently captured by Iraqi forces and shared with American advisors appear to be commercial, off-the-shelf models, adapted to carry grenade-sized payloads. "It's not as if it is a large, armed UAV [unmanned aerial vehicle] that is dropping munitions from the wings -- but literally, a very small quadcopter that drops a small munition in a somewhat imprecise manner," [Col. Brett] Sylvia, commander of an American military advising mission in Iraq, told Military Times. "They are very short-range, targeting those front-line troops from the Iraqis." Because the drones used are commercial models, it likely means that anti-drone weapons already on hand with the American advisors are sufficient to stop them. It's worth noting that the bomb-dropping drones are just a small part of how ISIS uses the cheap, unmanned flying machines. Other applications include scouts and explosive decoys, as well as one-use weapons. ISIS is also likely not the first group to figure out how to drop grenades from small drones; it's a growing field of research and development among many violent, nonstate actors and insurgent groups. Despite the relative novelty, it's also likely not the deadliest thing insurgents can do with drones.

New submitter drunkdrone writes: "French authorities investigating the EgyptAir crash that killed 66 people last year believe that the plane may have been brought down by an overheating phone battery," reports International Business Times. Investigators say the fire that broke out on the Airbus A320 in May 2016 started in the spot where the co-pilot had stowed his iPad and iPhone 6S, which he placed on top of the instrument panel in the plane's cockpit. From the report: "EgyptAir flight MS804 was traveling from Paris to Cairo when it disappeared from radar on 19 May 2016. Egyptian investigators have speculated that the crash, which killed all 56 passengers, seven crew members and three security personnel on board, was caused by an act of terrorism due to traces of explosives reported to be found on some the victims. Investigators in France have disputed these claims, saying that data recorded from the aircraft around the time it disappeared points to an accidental fire on the right-hand side of the flight deck, next to the co-pilot. According to The Times, CCTV pulled from cameras at Paris' Charles de Gualle airport show that the co-pilot stored a number of personal items above the dashboard, where the first signs of trouble were detected. This included an automated alert indicating a series of malfunctions on the right-hand flight deck window, followed by smoke alerts going off in a toilet and in the avionics area below the cockpit, minutes before the plane vanished."

The more drones being sold around the world increases the likelihood of them being used as part of a criminal act. For example, ISIS has been using drones in Iraq to carry and drop explosives. In an effort to protect consumers, an Australian and U.S. company called DroneShield has announced a product called the DroneGun. The DroneGun "allows for a controlled management of drone payload, such as explosives, with no damage to common drone models or the surrounding environment," the maker says on its website, "due to the drones generally responding via a vertical controlled landing on the spot, or returning back to the starting point (assisting to track the operator)." The Next Web reports: DroneGun, a handheld anti-drone device, has a range of 1.2 miles. It also looks like an unlockable item in a first-person shooter. The "gun" uses a jammer to disable electronic communication across the 2.4 and 5.8 GHz frequencies. Blocking these frequencies cuts off communication between the drone and pilot (or GPS) and forces it to land safely or return to its operator -- which assists in tracking the offending party. At 13 pounds, it's a bit cumbersome, but still capable of being operated by one person. It's also mostly a point-and-shoot device and doesn't require specialized training to use. DroneGun isn't approved for use in the United States -- thanks, FCC. If approved the device could provide a useful tool for taking down drones at airports, over crowded spaces, and in war zones.
