Feds going undercover on Facebook, Twitter, other social networking sites

The Feds are on Facebook. And MySpace, LinkedIn and Twitter, too.

U.S. law enforcement agents are following the rest of the Internet world into popular social-networking services, going undercover with false online profiles to communicate with suspects and gather private information,
according to an internal Justice Department document that offers a tantalizing glimpse of issues related to privacy and crime-fighting.

Think you know who’s behind that “friend” request? Think again. Your new “friend” just might be the FBI. The document, obtained in a Freedom of Information Act lawsuit, makes clear that U.S. agents are already logging on surreptitiously to exchange messages with suspects, identify a target’s friends or relatives and browse private information such as postings, personal photographs and video clips.

Among other purposes: Investigators can check suspects’ alibis by comparing stories told to police with tweets sent at the same time about their whereabouts. Online photos from a suspicious spending spree — people posing with jewelry, guns or fancy cars — can link suspects or their friends to robberies or burglaries.

The Electronic Frontier Foundation, a San Francisco-based civil liberties group, obtained the Justice Department document when it sued the agency and five others in federal court.

A decade ago, agents kept watch over AOL and MSN chat rooms to nab sexual predators. But those text-only chat services are old-school compared with today’s social media, which contain mountains of personal data, photographs, videos and audio clips — a potential treasure trove of evidence for
cases of violent crime, financial fraud and much more.

The Justice Department document, part of a presentation given in August by top cybercrime officials, describes the value of Facebook, Twitter, MySpace, LinkedIn and other services to government investigators. It does not describe in detail the boundaries for using them.

“It doesn’t really discuss any mechanisms for accountability or ensuring that government agents use those tools responsibly,” said Marcia Hoffman, a senior attorney with the Electronic Frontier Foundation.

The group sued in Washington to force the government to disclose its
policies for using social networking sites in investigations, data collection and surveillance.

Covert investigations on social-networking services are legal and governed by internal rules, according to Justice Department officials. But they would not say what those rules are.

The Justice Department document raises a legal question about a social-media bullying case in which U.S. prosecutors charged a Missouri woman with computer fraud for creating a fake MySpace account — effectively the same activity that undercover agents are doing, although for different purposes.

The woman, Lori Drew, helped create an account for a fictitious teen boy on MySpace and sent flirtatious messages to a 13-year-old neighborhood girl in his name. The girl hanged herself in October 2006, in a St. Louis suburb, after she received a message saying the world would be better without her.

A jury in California, where MySpace has its servers, convicted Drew of three misdemeanor counts of accessing computers without authorization because she was accused of violating MySpace’s rules against creating fake accounts. But last year a judge overturned the verdicts, citing the vagueness of the law.

“If agents violate terms of service, is that 'otherwise illegal activity’?” the document asks. It doesn’t provide an answer.

Facebook’s rules, for example, specify that users “will not provide any false personal information on Facebook, or create an account for anyone other than yourself without permission.” Twitter’s rules prohibit its users from sending deceptive or false information. MySpace requires that information for accounts be “truthful and accurate.”

A former U.S. cybersecurity prosecutor, Marc Zwillinger, said investigators should be able to go undercover in the online world the same way they do in the real world, even if such conduct is barred by a company’s rules. But there have to be limits, he said.

In the face-to-face world, agents can’t impersonate a suspect’s spouse, child, parent or best friend. But online, behind the guise of a social-networking account, they can.

“This new situation presents a need for careful oversight so that law enforcement does not use social networking to intrude on some of our most personal relationships,” said Zwillinger, whose firm does legal work for Yahoo and MySpace.

The Justice document describes how Facebook, MySpace and Twitter have interacted with federal investigators: Facebook is “often cooperative with emergency requests,” the government said. MySpace preserves information about its users indefinitely and even stores data from deleted accounts for one year. But Twitter’s lawyers tell prosecutors they need a warrant or subpoena before the company turns over customer information, the document says.

“Will not preserve data without legal process,” the document says under the heading, “Getting Info From Twitter ... the bad news.”

Twitter did not respond to a request for comment for this story.

The chief security officer for MySpace, Hemanshu Nigam, said MySpace doesn’t want to be the company that stands in the way of an investigation. “That said, we also want to make sure that our users’ privacy is protected and any data that’s disclosed is done under proper legal process,” Nigam said.

MySpace requires a search warrant for private messages less than six months old, according to the company.

Facebook spokesman Andrew Noyes said the company has put together a handbook to help law enforcement officials understand “the proper ways to request information from Facebook to aid investigations.”
