NSA Intercepts Used to Convict Liquid Bombers

Three of the UK liquid bombers were convicted Monday. NSA-intercepted e-mail was introduced as evidence in the trial:

The e-mails, several of which have been reprinted by the BBC and other publications, contained coded messages, according to prosecutors. They were intercepted by the NSA in 2006 but were not included in evidence introduced in a first trial against the three last year.

That trial resulted in the men being convicted of conspiracy to commit murder; but a jury was not convinced that they had planned to use soft drink bottles filled with liquid explosives to blow up seven trans-Atlantic planes—the charge for which they were convicted this week in a second trial.

According to Channel 4, the NSA had previously shown the e-mails to their British counterparts, but refused to let prosecutors use the evidence in the first trial, because the agency didn’t want to tip off an alleged accomplice in Pakistan named Rashid Rauf that his e-mail was being monitored. U.S. intelligence agents said Rauf was al Qaeda’s director of European operations at the time and that the bomb plot was being directed by Rauf and others in Pakistan.

The NSA later changed its mind and allowed the evidence to be introduced in the second trial, which was crucial to getting the jury conviction. Channel 4 suggests the NSA’s change of mind occurred after Rauf, a Briton born of Pakistani parents, was reportedly killed last year by a U.S. drone missile that struck a house where he was staying in northern Pakistan.

Although British prosecutors were eager to use the e-mails in their second trial against the three plotters, British courts prohibit the use of evidence obtained through interception. So last January, a U.S. court issued warrants directly to Yahoo to hand over the same correspondence.

It’s unclear if the NSA intercepted the messages as they passed through internet nodes based in the U.S. or intercepted them overseas.

EDITED TO ADD (9/9): Just to be sure, this has nothing to do with any illegal warrantless wiretapping the NSA has done over the years; the wiretap used to intercept these e-mails was obtained with a FISA warrant.

Marine Worms with Glowing Bombs

More security stories from the natural world:

During chase scenes, movie protagonists often make their getaway by releasing some sort of decoy to cover their escape or distract their pursuer. But this tactic isn’t reserved for action heroes—some deep-sea animals also evade their predators by releasing decoys—glowing ones.

Karen Osborn from the Scripps Institute of Oceanography has discovered seven new species of closely related marine worms (annelids) that use this trick. Each species pack up to four pairs of “bombs” near their heads—simple, fluid-filled globes that the worms can detach at will. When released, the “bombs” give off an intense light that lasts for several seconds.

My two previous posts on the topic.

Movie-Plot Threat Alert: Robot Suicide Bombers

Let’s all be afraid:

But it adds: “Robots that effectively mimic human appearance and movements may be used as human proxies.”

It raised the prospects of terrorists using robots to plant and detonate bombs or even replacing human suicide bombers.

A Home Office spokeswoman said: “This strategy looks at how technology might develop in future.

“Clearly it is important that we understand how those wishing us harm might use such technology in future so we can stay one step ahead.”

The document also warns that nanotechnology will help accelerate development of materials for future explosives while advances in fabrics will “significantly” improve camouflage and protection.

I’m sure I’ve seen this stuff in movies.

How we Reacted to the Unexpected 75 Years Ago

A 1934 story from the International Herald Tribune:

Dynamite Found On Track

SPOKANE Discovery of a box of useless dynamite on the railway track two and a half miles southwest of this city led to special precautions being taken to guard the line over which President Roosevelt’s train passed this morning [August 4] en route to Washington. Six deputy sheriffs guarded the section of the line near which the discovery was made. The President’s train passed safely at 10 a.m. Officials are skeptical about the dynamite having any connection with a possible plot against the President.

Imagine if the same thing happened today.

Verifiable Dismantling of Nuclear Bombs

Cryptography has zero-knowledge proofs, where Alice can prove to Bob that she knows something without revealing it to Bob. Here’s something similar from the real world. It’s a research project to allow weapons inspectors from one nation to verify the disarming of another nation’s nuclear weapons without learning any weapons secrets in the process, such as the amount of nuclear material in the weapon.

Lost Suitcases in Airport Restrooms

Want to cause chaos at an airport? Leave a suitcase in the restroom:

Three incoming flights from London were cancelled and about 150 others were delayed for up to three hours, while the army’s bomb squad carried out its investigation, before giving the all-clear at about 5pm.

Passengers were told to leave the arrivals hall, main check-in area at the terminal building, the food courts and shops, and gather at safety areas outside.

The scare led to major traffic disruption around the airport, with tailbacks stretching back about a mile. Some passengers faced lengthy walks to the airport after being dropped off by shuttle bus from the city centre.

Oddest quote is from a police spokesperson:

“Inquires are under way to establish how the luggage came to be located within the toilets.”

My guess is that someone left it there.

I’d suggest this as a good denial-of-service attack, but certainly there is a video camera recording of the person bringing the suitcase into the airport. The article says it was left in the “domestic arrivals area.” I don’t know if that’s inside airport security or not.

Terrorist Risk of Cloud Computing

I don’t even know where to begin on this one:

As we have seen in the past with other technologies, while cloud resources will likely start out decentralized, as time goes by and economies of scale take hold, they will start to collect into mega-technology hubs. These hubs could, as the end of this cycle, number in the low single digits and carry most of the commerce and data for a nation like ours. Elsewhere, particularly in Europe, those hubs could handle several nations’ public and private data.

And therein lays the risk.

The Twin Towers, which were destroyed in the 9/11 attack, took down a major portion of the U.S. infrastructure at the same time. The capability and coverage of cloud-based mega-hubs would easily dwarf hundreds of Twin Tower-like operations. Although some redundancy would likely exist—hopefully located in places safe from disasters—should a hub be destroyed, it could likely take down a significant portion of the country it supported at the same time.

[…]

Each hub may represent a target more attractive to terrorists than today’s favored nuclear power plants.

It’s only been eight years, and this author thinks that the 9/11 attacks “took down a major portion of the U.S. infrastructure.” That’s just plain ridiculous. I was there (in the U.S, not in New York). The government, the banks, the power system, commerce everywhere except lower Manhattan, the Internet, the water supply, the food supply, and every other part of the U.S. infrastructure I can think of worked just fine during and after the attacks. The New York Stock Exchange was up and running in a few days. Even the piece of our infrastructure that was the most disrupted—the airplane network—was up and running in a week. I think the author of that piece needs to travel to somewhere on the planet where major portions of the infrastructure actually get disrupted, so he can see what it’s like.

No less ridiculous is the main point of the article, which seems to imply that terrorists will someday decide that disrupting people’s Lands’ End purchases will be more attractive than killing them. Okay, that was a caricature of the article, but not by much. Terrorism is an attack against our minds, using random death and destruction as a tactic to cause terror in everyone. To even suggest that data disruption would cause more terror than nuclear fallout completely misunderstands terrorism and terrorists.

And anyway, any e-commerce, banking, etc. site worth anything is backed up and dual-homed. There are lots of risks to our data networks, but physically blowing up a data center isn’t high on the list.

More Security Countermeasures from the Natural World

The plant caladium steudneriifolium pretends to be ill so mining moths won’t eat it.

She believes that the plant essentially fakes being ill, producing variegated leaves that mimic those that have already been damaged by mining moth larvae. That deters the moths from laying any further larvae on the leaves, as the insects assume the previous caterpillars have already eaten most of the leaves’ nutrients.

Cabbage aphids arm themselves with chemical bombs:

Its body carries two reactive chemicals that only mix when a predator attacks it. The injured aphid dies. But in the process, the chemicals in its body react and trigger an explosion that delivers lethal amounts of poison to the predator, saving the rest of the colony.

The dark-footed ant spider mimics an ant so that it’s not eaten by other spiders, and so it can eat spiders itself:

M.melanotarsa is a jumping spider that protects itself from predators (like other jumping spiders) by resembling an ant. Earlier this month, Ximena Nelson and Robert Jackson showed that they bolster this illusion by living in silken apartment complexes and travelling in groups, mimicking not just the bodies of ants but their social lives too.

Now Nelson and Robert are back with another side to the ant-spider’s tale – it also uses its impersonation for attack as well as defence. It also feasts on the eggs and youngsters of the very same spiders that its ant-like form protects it from. It is, essentially, a spider that looks like an ant to avoid being eaten by spiders so that it itself can eat spiders.

Carrot-Bomb Art Project Bombs in Sweden

Not the best idea:

The carrot bombs had been placed around the city at the request of a local art gallery, as part of an open-air arts festival.

They had only been in place for an hour before police received their first call.

“We received a call … from a person who said they saw two real bombs placed outside the public library,” Ronny Hoerman from the Orebro police force, was quoted as saying by the AFP news agency.

“It was hard to tell if they were real or not. We find this inappropriate,” he said.

Mr Blom described it as a harmless stunt.

“After all, it is just carrots with an alarm clock and nothing else… this is just a caricature of a bomb,” he said.

This Week's Terrorism Arrests

Four points. One: There was little danger of an actual terrorist attack:

Authorities said the four men have long been under investigation and there was little danger they could actually have carried out their plan, NBC News’ Pete Williams reported.

[…]

In their efforts to acquire weapons, the defendants dealt with an informant acting under law enforcement supervision, authorities said. The FBI and other agencies monitored the men and provided an inactive missile and inert C-4 to the informant for the defendants, a federal complaint said.

The investigation had been under way for about a year.

“They never got anywhere close to being able to do anything,” one official told NBC News. “Still, it’s good to have guys like this off the street.”

Of course, politicians are using this incident to peddle more fear:

“This was a very serious threat that could have cost many, many lives if it had gone through,” Representative Peter T. King, Republican from Long Island, said in an interview with WPIX-TV. “It would have been a horrible, damaging tragedy. There’s a real threat from homegrown terrorists and also from jailhouse converts.”

Two, they were caught by traditional investigation and intelligence. Not airport security. Not warrantless eavesdropping. But old fashioned investigation and intelligence. This is what works. This is what keeps us safe. Here’s an essay I wrote in 2004 that says exactly that.

The only effective way to deal with terrorists is through old-fashioned police and intelligence work—discovering plans before they’re implemented and then going after the plotters themselves.

Three, they were idiots:

The ringleader of the four-man homegrown terror cell accused of plotting to blow up synagogues in the Bronx and military planes in Newburgh admitted to a judge today that he had smoked pot before his bust last night.

When U.S. Magistrate Judge Lisa M. Smith asked James Cromitie if his judgment was impaired during his appearance in federal court in White Plains, the 55-year-old confessed: “No. I smoke it regularly. I understand everything you are saying.”

Four, an “informant” helped this group a lot:

In April, Mr. Cromitie and the three other men selected the synagogues as their targets, the statement said. The informant soon helped them get the weapons, which were incapable of being fired or detonated, according to the authorities.

The warning the warning I wrote in “Portrait of the Modern Terrorist as an Idiot” is timely again:

Despite the initial press frenzies, the actual details of the cases frequently turn out to be far less damning. Too often it’s unclear whether the defendants are actually guilty, or if the police created a crime where none existed before.

The JFK Airport plotters seem to have been egged on by an informant, a twice-convicted drug dealer. An FBI informant almost certainly pushed the Fort Dix plotters to do things they wouldn’t have ordinarily done. The Miami gang’s Sears Tower plot was suggested by an FBI undercover agent who infiltrated the group. And in 2003, it took an elaborate sting operation involving three countries to arrest an arms dealer for selling a surface-to-air missile to an ostensible Muslim extremist. Entrapment is a very real possibility in all of these cases.

Actually, that whole 2007 essay is timely again. Some things never change.
