Corporate Spying

This is a good article on a new trend in corporate spying: companies like Wal-Mart and Sears have resorted to covert surveillance of employees, partners, journalists, and even Internet users to protect itself from “global threats.”

“Like most major corporations, it is our corporate responsibility to have systems in place, including software systems, to monitor threats to our network, intellectual property and our people,” Wal-Mart spokeswoman Sarah Clark said in a statement in April. Following the Gabbard firing, Wal-Mart said it conducted a review of its monitoring activities. “There have been changes in leadership, and we have strengthened our practices and protocols in this area,” Clark said.

[…]

At a gathering of security specialists in New York City in January of 2006, David Harrison, the former Army military intelligence officer who was hired by Senser to head Wal-Mart’s analytical security research center, provided a rare glimpse into the company’s monitoring operations. Harrison told the gathering Wal-Mart faces a wide range of threats: “A bombing in China, an armed robbery in Brazil, an armed robbery in Las Vegas, another bomb threat, and that was just yesterday,” Harrison said.

To safeguard its employees and operations Wal-Mart has tapped its massive data warehouse of information, now believed to be larger than 4 petabytes (4,000 terabytes), to look for potential threats. It tracks customers who buy propane tanks, for example, or anyone who has fraudulently cashed a check, or anyone making bulk purchases of pre-paid cell phones, which could be tied to criminal activities. “If you try to buy more than three cell phones at one time, it will be tracked,” he reportedly told the audience.

[…]

Gabbard, the Wal-Mart employee fired for recording reporters’ phone calls, said in his interview with The Wall Street Journal that Wal-Mart uses software from Raytheon Oakley Networks to monitor activity on its network. The Oakley product was originally developed for the U.S. Department of Defense.

The Oakley software is so sophisticated it can allow administrators to visually see what types of information are moving across the network, from Excel spreadsheets to job searches on Monster.com, or photos with flesh tones that might indicate a user is viewing pornography.

And this article talks about ex-CIA agents working for corporations:

The best estimate is that several hundred former intelligence agents now work in corporate espionage, including some who left the C.I.A. during the agency turmoil that followed 9/11. They quickly joined private-investigation firms whose U.S. corporate clients were planning to expand into Russia, China, and other countries with opaque business practices and few public records, and who needed the skinny on international partners or rivals.

These ex-spies apply a higher level of expertise, honed by government service, to the cruder tactics already practiced by private investigators. One such ploy is pretexting—obtaining information by pretending to be somebody else. While private detectives have long posed as freelance reporters or job recruiters to get people to talk, former agents have elevated pretexting to an art.

[…]

Similarly, ex-agents have helped popularize the use of G.P.S.-based monitoring devices and long-range cameras for following people around. One corporate-espionage technique comes straight from the C.I.A. playbook. In the constant search for the slightest edge, some hedge funds and investment companies have turned to a handful of private-investigation firms for a tactic that seems to fall between science and voodoo. Called tactical behavior assessment, it relies on dozens of verbal and nonverbal cues to determine whether someone is lying. Signs of potential deception include meandering off topic rather than sticking to the facts and excessive personal grooming, such as nervously picking lint off a jacket. This method was developed by former lie-detector experts from the C.I.A.’s Office of Security, which administers polygraph tests to keep agents honest and verify the stories of would-be defectors.

[…]

Most of the ex-agents’ activities, from surveillance to lie detection, are perfectly legal. In the wake of the 2006 Hewlett-Packard scandal, detectives used pretexting to obtain the private telephone records of company directors, employees, and journalists. In an effort to track leaks to the media, federal law was tightened to prohibit using fraudulent means to obtain telephone records. Financial records were already off-limits. But federal law doesn’t forbid assuming a false identity to get other information—an area that ex-spies exploit.

Still, a few techniques favored by the spies-for-hire do appear to violate privacy statutes. One of these involves using “data haunts,” extreme methods of electronic monitoring such as tracking cell-phone calls and gathering emails by relying on secretly installed software to record computer keystrokes. An ex-C.I.A. agent described a group of his former colleagues who set up shop offshore so that they could tap into telephone calls—a practice prohibited by federal law—outside U.S. jurisdiction. “They call themselves the bad boys in the Bahamas,” he said.

Even some of the legal methods are controversial within the industry. Certain old-school firms won’t stoop to dumpster diving or stealing garbage—which is usually legal as long as the trash is on a curb or other public property—” because they consider it unethical. They say that the prevalence of former intelligence agents in the field and the rise of unscrupulous tactics have tarnished a business that often struggles with its reputation. One longtime investigator complained that he recently lost business to some ex-C.I.A. officers who promised a potential client that they could obtain the phone and bank records of a target—something that is illegal in most cases.

[…]

Current and former employees said Diligence’s ex-spies also held classes in using false identities to obtain confidential information. Ex-employees said it wasn’t unusual for an investigator to have five or six cell phones, each representing a different identity, on his or her desk. And while ex-C.I.A. and former MI5 agents were old hands at such deception, the new initiates sometimes got confused and answered a phone with the wrong name.

All interesting. It seems that corporate espionage has gone mainstream, and the debate is more about how and when.

On a related note, this paragraph disturbed me:

On occasion, Diligence investigators were dispatched to collect garbage from a target’s home or office. In some cases, two former employees said, Diligence hired off-duty or retired police officers to take trash so that they could wave their badges and fend off any awkward questions.

It’s public authority being used for private interests. We see it a lot—off-duty police officers guarding private businesses, for example—and it erodes public trust of authority. In the case above, I’m not even sure it’s legal.

My Open Wireless Network

Whenever I talk or write about my own security setup, the one thing that surprises people—and attracts the most criticism—is the fact that I run an open wireless network at home. There’s no password. There’s no encryption. Anyone with wireless capability who can see my network can use it to access the internet.

To me, it’s basic politeness. Providing internet access to guests is kind of like providing heat and electricity, or a hot cup of tea. But to some observers, it’s both wrong and dangerous.

I’m told that uninvited strangers may sit in their cars in front of my house, and use my network to send spam, eavesdrop on my passwords, and upload and download everything from pirated movies to child pornography. As a result, I risk all sorts of bad things happening to me, from seeing my IP address blacklisted to having the police crash through my door.

While this is technically true, I don’t think it’s much of a risk. I can count five open wireless networks in coffee shops within a mile of my house, and any potential spammer is far more likely to sit in a warm room with a cup of coffee and a scone than in a cold car outside my house. And yes, if someone did commit a crime using my network the police might visit, but what better defense is there than the fact that I have an open wireless network? If I enabled wireless security on my network and someone hacked it, I would have a far harder time proving my innocence.

This is not to say that the new wireless security protocol, WPA, isn’t very good. It is. But there are going to be security flaws in it; there always are.

I spoke to several lawyers about this, and in their lawyerly way they outlined several other risks with leaving your network open.

While none thought you could be successfully prosecuted just because someone else used your network to commit a crime, any investigation could be time-consuming and expensive. You might have your computer equipment seized, and if you have any contraband of your own on your machine, it could be a delicate situation. Also, prosecutors aren’t always the most technically savvy bunch, and you might end up being charged despite your innocence. The lawyers I spoke with say most defense attorneys will advise you to reach a plea agreement rather than risk going to trial on child-pornography charges.

In a less far-fetched scenario, the Recording Industry Association of America is known to sue copyright infringers based on nothing more than an IP address. The accuser’s chance of winning is higher than in a criminal case, because in civil litigation the burden of proof is lower. And again, lawyers argue that even if you win it’s not worth the risk or expense, and that you should settle and pay a few thousand dollars.

I remain unconvinced of this threat, though. The RIAA has conducted about 26,000 lawsuits, and there are more than 15 million music downloaders. Mark Mulligan of Jupiter Research said it best: “If you’re a file sharer, you know that the likelihood of you being caught is very similar to that of being hit by an asteroid.”

I’m also unmoved by those who say I’m putting my own data at risk, because hackers might park in front of my house, log on to my open network and eavesdrop on my internet traffic or break into my computers. This is true, but my computers are much more at risk when I use them on wireless networks in airports, coffee shops and other public places. If I configure my computer to be secure regardless of the network it’s on, then it simply doesn’t matter. And if my computer isn’t secure on a public network, securing my own network isn’t going to reduce my risk very much.

Yes, computer security is hard. But if your computers leave your house, you have to solve it anyway. And any solution will apply to your desktop machines as well.

Finally, critics say someone might steal bandwidth from me. Despite isolated court rulings that this is illegal, my feeling is that they’re welcome to it. I really don’t mind if neighbors use my wireless network when they need it, and I’ve heard several stories of people who have been rescued from connectivity emergencies by open wireless networks in the neighborhood.

Similarly, I appreciate an open network when I am otherwise without bandwidth. If someone were using my network to the point that it affected my own traffic or if some neighbor kid was dinking around, I might want to do something about it; but as long as we’re all polite, why should this concern me? Pay it forward, I say.

Certainly this does concern ISPs. Running an open wireless network will often violate your terms of service. But despite the occasional cease-and-desist letter and providers getting pissy at people who exceed some secret bandwidth limit, this isn’t a big risk either. The worst that will happen to you is that you’ll have to find a new ISP.

A company called Fon has an interesting approach to this problem. Fon wireless access points have two wireless networks: a secure one for you, and an open one for everyone else. You can configure your open network in either “Bill” or “Linus” mode: In the former, people pay you to use your network, and you have to pay to use any other Fon wireless network. In Linus mode, anyone can use your network, and you can use any other Fon wireless network for free. It’s a really clever idea.

Security is always a trade-off. I know people who rarely lock their front door, who drive in the rain (and, while using a cell phone) and who talk to strangers. In my opinion, securing my wireless network isn’t worth it. And I appreciate everyone else who keeps an open wireless network, including all the coffee shops, bars and libraries I have visited in the past, the Dayton International Airport where I started writing this and the Four Points Sheraton where I finished. You all make the world a better place.

This essay originally appeared on Wired.com, and has since generated a lot of controversy. There’s a Slashdot thread. And here are three opposing essays and three supporting essays. Presumably there will be a lot of back and forth in the comments section here as well.

EDITED TO ADD (1/15): There has been lots more commentary.

EDITED TO ADD (1/16): Even more commentary. And still more.

EDITED TO ADD (1/17): Two more.

EDITED TO ADD (1/18): Another. In the beginning, comments agreeing with me and disagreeing with me were about tied. By now, those that disagree with me are firmly in the lead.

How Well "See Something, Say Something" Actually Works

I’ve written about the “War on the Unexpected,” and how normal people can’t figure out what’s an actual threat and what isn’t:

All they know is that something makes them uneasy, usually based on fear, media hype, or just something being different.

[…]

If you ask amateurs to act as front-line security personnel, you shouldn’t be surprised when you get amateur security.

Yesterday The New York Times wrote about New York City’s campaign:

Now, an overview of police data relating to calls to the hot line over the past two years reveals the answer and provides a unique snapshot of post-9/11 New York, part paranoia and part well-founded caution. Indeed, no terrorists were arrested, but a wide spectrum of other activity was reported.

[…]

In all, the hot line received 8,999 calls in 2006, including calls that were transferred from 911 and the 311 help line, Mr. Browne said. They included a significant number of calls about suspicious packages, many in the transit system. Most involved backpacks, briefcases or other items accidentally left behind by their owners. None of them, Mr. Browne said, were bombs.

There were, however, 816 calls to the hot line in 2006 that were deemed serious enough to require investigation by the department’s intelligence division or its joint terrorism task force with the F.B.I. Mr. Browne said that 109 of those calls had a connection to the transit system and included reports of suspicious people in tunnels and yards, and of people taking pictures of the tracks.

The hot line received many more calls in 2007, possibly because of the authority’s advertising campaign, Mr. Browne said. Through early December, the counterterrorism hot line received 13,473 calls, with 644 of those meriting investigation. Of that group, 45 calls were transit related.

Then there were the 11 calls about people counting.

Mr. Browne said several callers reported seeing men clicking hand-held counting devices while riding on subway trains or waiting on platforms.

The callers said that the men appeared to be Muslims and that they seemed to be counting the number of people boarding subway trains or the number of trains passing through a station. They feared the men might be collecting data to maximize the casualties in a terror attack.

But when the police looked into the claims, they determined that the men were counting prayers with the devices, essentially a modern version of rosary beads.

None of those calls led to arrests, but several others did. At least three calls resulted in arrests for trying to sell false identification, including driver’s licenses and Social Security cards. One informer told the police about a Staten Island man who was later found to have a cache of firearms. A Queens man was charged with having an illegal gun and with unlawful dealing in fireworks.

A Brooklyn man was charged with making anti-Semitic threats against his landlord and threatening to use sarin gas on him. At least two men arrested on tips from the hot line were turned over to immigration officials for deportation, Mr. Browne said.

And as long as we’re on the topic, read about the couple branded as terrorists in the UK for taking photographs in a mall. And this about a rail fan being branded a terrorist for trying to film a train. (Note that the member of the train’s crew was trying to incite the other passengers to do something about the filmer.) And about this Icelandic woman’s experience with U.S. customs because she overstayed a visa in 1995.

And lastly, this funny piece of (I trust) fiction.

Remember that every one of these incidents requires police resources to investigate, resources that almost certainly could be better spent keeping us actually safe.

Refuse to be terrorized!

Airport Behavioral Profiling Leads to an Arrest

I’m generally a fan of behavioral profiling. While it sounds weird and creepy and has been likened to Orwell’s “facecrime”, there’s no doubt that—when done properly—it works at catching common criminals:

On Dec. 4, Juan Carlos Berriel-Castillo, 22, and Bernardo Carmona-Olivares, 20, were planning to fly to Maui but were instead arrested on suspicion of forgery.

They tried to pass through a Terminal 4 security checkpoint with suspicious documents, Phoenix police spokeswoman Stacie Derge said.

The pair had false permanent-resident identification, and authorities also found false Social Security cards, officials say.

While the pair were questioned about the papers, a TSA official who had received behavior-recognition training observed a third man in the area who appeared to be connected to Berriel-Castillo and Carmona-Olivares, Melendez said.

As a result, police later arrested Samuel Gonzalez, 32. A background check revealed that Gonzalez was wanted on two misdemeanor warrants.

TSA press release here.

Security is a trade-off. The question is whether the expense of the Screening Passengers by Observation Techniques (SPOT) program, given the minor criminals it catches, is worth it. (Remember, it’s supposed to catch terrorists, not people with outstanding misdemeanor warrants.) Especially with the 99% false alarm rate:

Since January 2006, behavior-detection officers have referred about 70,000 people for secondary screening, Maccario said. Of those, about 600 to 700 were arrested on a variety of charges, including possession of drugs, weapons violations and outstanding warrants.

And the other social costs, including loss of liberty, restriction of fundamental freedoms, and the creation of a thoughtcrime. Is this the sort of power we want to give a police force in a constitutional democracy, or does it feel more like a police-state sort of thing?

This “Bizarro” cartoon sums it up nicely.

Police Helping Thieves

This is a weird article. Local police are putting yellow stickers on cars with visible packages, making it easier for thieves to identify which cars are worth breaking into.

How odd.

EDITED TO ADD 12/19): According to a comment, this was misreported in the news. The police didn’t just put signs on cars with visible packages, but on all cars. Cars with no visible packages got a note saying: “Nothing Observed (Good Job!).” So a thief would have to read the sign, which means he’s already close enough to look in the car. Much better.

Secretly Recording Interrogations

It’s getting easier to watch the watchers:

A teen suspect’s snap decision to secretly record his interrogation with an MP3 player has resulted in a perjury case against a veteran detective and a plea deal for the teen.

Unaware of the recording, Detective Christopher Perino insisted under oath at a trial in April that suspect Erik Crespo wasn’t questioned about a shooting in the Bronx.

But the defense confronted the detective with a transcript it said proved he had spent more than an hour unsuccessfully trying to persuade Crespo to confess.

Perino was arraigned today on 12 counts of first-degree perjury and freed on bail.

My guess is that this sort of perjury occurs more than we realize. If there’s one place I think cameras should be rolling at all times, it’s in police station interrogation rooms. And no erasing the tapes either. (And those tapes must have been really damning. Old interrogation tapes can yield valuable intelligence; you don’t ever erase them unless you absolutely have to.)

Animal Rights Activists Forced to Hand Over Encryption Keys

In the UK:

In early November about 30 animal rights activists are understood to have received letters from the Crown Prosecution Service in Hampshire inviting them to provide passwords that will decrypt material held on seized computers.

The letter is the first stage of a process set out under RIPA which governs how the authorities handle requests to examine encrypted material.

Once a request has been issued the authorities can then issue what is known as a Section 49 notice demanding that a person turn the data into an “intelligible” form or, under Section 51 hand over keys.

Although much of RIPA came into force many years ago, the part governing the handing over of keys only passed in to law on 1 October 2007. This is why the CPS is only now asking for access to files on the seized machines.

Alongside a S49 notice, the authorities can also issue a Section 54 notice that prevents a person revealing that they are subject to this part of RIPA.

Actually, we don’t know if the activists actually handed the police their encryption keys yet. More about the law here.

If you remember, this was sold to the public as essential for fighting terrorism. It’s already being misused.

Firefighters to Fight Terrorism While Doing their Day Jobs

In yet another front in the war on the unexpected, more amateurs are joining the fight against terrorism:

Unlike police, firefighters and emergency medical personnel don’t need warrants to access hundreds of thousands of homes and buildings each year, putting them in a position to spot behavior that could indicate terrorist activity or planning.

[…]

When going to private residences, for example, they are told to be alert for a person who is hostile, uncooperative or expressing hate or discontent with the United States; unusual chemicals or other materials that seem out of place; ammunition, firearms or weapons boxes; surveillance equipment; still and video cameras; night-vision goggles; maps, photos, blueprints; police manuals, training manuals, flight manuals; and little or no furniture other than a bed or mattress.

Because it’s such a good idea for people to start fearing firefighters….
