Fewer Russian spies in U.S. but getting harder to track

WASHINGTON (Reuters) – The U.S. decision to expel 60 alleged spies is unlikely to cripple Russian spying in the United States because others have wormed and hacked their way into American companies, schools, and even the government, current and former U.S. officials said.

Moscow’s spy services still use the cover of embassies and consulates, as Washington does. But they also recruit Russian emigres, establish front companies, dispatch short-term travelers to the United States, recruit Americans, and penetrate computer networks, the officials said.

“Russia used to have one way of doing things. Now, Putin is – let a thousand flowers bloom,” a former senior U.S. official said in a recent interview, describing Moscow’s move to a more multifaceted approach under President Vladimir Putin, a former Soviet spy himself.

The FBI follows the movements and monitors the communications of suspected foreign spies, but the increased Russian presence and the advent of commercially available encrypted communications are an added challenge to the FBI’s counter-espionage force, said the officials, some of whom spoke on condition of anonymity to discuss the sensitive topic.

As one U.S. official put it when asked if Russian spying is a harder target: “It’s more complex now. The complexity comes in the techniques that can be used.”

While the CIA tracks foreign spies overseas and the National Security Agency monitors international communications, the FBI is responsible for spy-catching inside the United States.

The White House on Monday said it would expel 60 Russian diplomats, 12 of them at the U.N. mission, and close the Russian consulate in Seattle as part of a multi-nation response to the Kremlin’s alleged nerve agent attack on a former Russian spy in Britain.

Briefing reporters, a senior U.S. official said there were “well over” 100 Russian spies posing as diplomats in the United States before the expulsion order.

A veteran U.S. official charged with keeping tabs on Russian espionage said the administration downplayed the number of suspected Russian spies working under diplomatic cover to avoid giving the Russians a clearer picture of how many people are under surveillance.

The actual number varies over time, but “it averages more like 150 or so,” the official said.

“We’ve got a very, very, very good counter-intelligence apparatus,” said Robert Litt, a former general counsel for the U.S. Director of National Intelligence. “There are a lot of people in the FBI whose job it is to track these people – and they’re very good at it.”

TAKES TEN TO TANGO

Still, it can take 10 or more U.S. trained FBI and local law enforcement officers to keep tabs on one trained spy for a 24-hour period – covering back entrances to buildings and multiple elevators, and being alert for changes in clothes, cars and even hairpieces, the same official said.

One Russian tactic is sending a large number of people, including just one or two intelligence officers, streaming out of a diplomatic mission at once, making it harder for the FBI to decide whom to follow, said a former U.S. intelligence officer, also speaking on the condition of anonymity.

Microsoft Corp. was one target of the Russian espionage operation in Seattle, U.S. officials familiar with the expulsions said. One goal was identifying targets for recruitment in the company’s coding operations because the company’s products are used in so many applications, they said.

Microsoft declined comment.

In 2010, Alexey Karetnikov, a 23-year-old Russian spy who had worked at testing computer code in Microsoft’s Richmond, Wash., headquarters, was deported by an immigration judge.

Several of the officials traced the Kremlin’s more aggressive spying approach to Putin’s 2012 return to the presidency, and Moscow’s 2014 seizure of Crimea and intervention in eastern Ukraine.

“We observed a commensurate uptick in Russian intelligence and espionage activity in the U.S. and across Europe, although few analysts connected the dots,” said Heather Conley, a former State Department official now at the Center for Strategic and International Studies think tank.

Michael Rochford, a former FBI chief for espionage, said the mass expulsion of suspected spies posing as diplomats will affect Russia’s security services and dent morale at their Moscow headquarters.

After past expulsions, he said, Russian spies have handed their operations over to officers who remain behind, or to “illegals” – long-term agents with no demonstrable connections to the Russian government.

The risk, he said, is that when Moscow replaces the expelled personnel, it will not be clear who the new spies are.

“Sometimes it’s better to know who they are and follow them,” he said.

Shooting near U.S. National Security Agency, several injuried

FORT MEADE, Maryland (Reuters) – Several people were injured during a Wednesday morning shooting at the U.S. National Security Agency headquarters in Fort Meade, Maryland, the agency said.

The incident occurred about 7 a.m. ET (1200 GMT) when a vehicle tried to enter the U.S. Army installation that houses the agency without authorization, the agency said in a statement. It said shots were fired but that none of the injuries appeared to have been caused by gunshots.

The statement did not make clear whether the shots had been fired by a suspect or by law enforcement and officials at the NSA and Federal Bureau of Investigation, which is investigating the incident, did not respond to questions about who fired weapons.

“Weapons were discharged in the course of the incident, which remains under investigation,” the agency said in a statement. “The situation is under control and there is no ongoing security of safety threat.”

It said several people were taken to hospitals from the facility about 30 miles (48 km) northeast of Washington.

Police earlier had searched a black sport utility vehicle with what appeared to bullet holes in its windshield, according to video from the scene. Items apparently removed from the vehicle were strewn on the ground and checked by a police dog.

Earlier media reports said that as many as three people had been wounded at the base, which is the home of the NSA, as well as the U.S. Cyber Command and Defense Information School.

The National Security Agency/Central Security Service is one of the U.S. government’s main spy agencies. The secretive agency focuses on using technological tools, including the monitoring of internet traffic, to monitor the government’s adversaries.

A White House spokeswoman said President Donald Trump had been briefed on the shooting.

Fort Meade is located just off a major Washington-area highway and motorists occasionally unintentionally take the exit that leads them to its gates, which are manned by armed guards.

In March 2015, two people tried to drive their sports utility vehicle through the NSA’s heavily guarded gate. Officers shot at the vehicle when they refused to stop, killing one of the occupants. The people in the vehicle may have taken a wrong turn after partying and taking drugs, according to news reports.

House to vote to renew NSA’s internet surveillance program

By Dustin Volz

(Reuters) – The U.S. House of Representatives plans to vote on Thursday on whether to renew the National Security Agency’s warrantless internet surveillance program, which has been the target of privacy advocates who want to limit its impact on Americans.

The vote is the culmination of a yearslong debate in Congress on the proper scope of U.S. intelligence collection, one fueled by the 2013 disclosures of classified surveillance secrets by former NSA contractor Edward Snowden.

The bill would extend the NSA’s spying program for six years with minimal changes. Most lawmakers expect it to become law if it prevails in the House, although it still would require Senate approval and President Donald Trump’s signature.

Trump appeared on Thursday to initially question the merits of the program, contradicting the official White House position and renewing unsubstantiated allegations that the previous administration of Barack Obama improperly surveilled his campaign during the 2016 election.

“This is the act that may have been used, with the help of the discredited and phony Dossier, to so badly surveil and abuse the Trump Campaign by the previous administration and others?” the president said in an early morning post on Twitter.

The White House did not immediately respond to a request to clarify Trump’s tweet but he posted a clarification less than two hours later.

“With that being said, I have personally directed the fix to the unmasking process since taking office and today’s vote is about foreign surveillance of foreign bad guys on foreign land. We need it! Get smart!” Trump tweeted.

Unmasking refers to the largely separate issue of how Americans’ names kept secret in intelligence reports can be revealed.

Asked by a Reuters reporter at a conference in New York about Trump’s tweets, Rob Joyce, the top White House cyber official, said there was no confusion within Oval Office about the value of the surveillance program and that there have been no cases of it being used improperly for political purposes.

Some conservative, libertarian-leaning Republicans and liberal Democrats were attempting to persuade colleagues to include more privacy protections. Those would include requiring a warrant before the NSA or other intelligence agencies could scrutinize communications belonging to Americans whose data is incidentally collected under the program.

The White House, U.S. intelligence agencies and Republican leaders in Congress have said they consider the tool indispensable and in need of little or no revision.

Without congressional action, legal support for Section 702 of the Foreign Intelligence Surveillance Act, which authorizes the program, will expire next week, although intelligence officials say it could continue through April.

Section 702 allows the NSA to eavesdrop on vast amounts of digital communications from foreigners living outside the United States through U.S. companies such as Facebook Inc, Verizon Communications Inc and Alphabet Inc’s Google.

The spying program also incidentally scoops up communications of Americans if they communicate with a foreign target living overseas, and can search those messages without a warrant.

Kaspersky says it obtained suspected NSA hacking code from U.S. computer

Kaspersky says it obtained suspected NSA hacking code from U.S. computer

By Joseph Menn

SAN FRANCISCO (Reuters) – Moscow-based Kaspersky Lab on Wednesday acknowledged that its security software had taken source code for a secret American hacking tool from a personal computer in the United States.

The admission came in a statement from the embattled company that described preliminary results from an internal inquiry it launched into media reports that the Russian government used Kaspersky anti-virus software to collect National Security Agency technology.

While the explanation is considered plausible by some security experts, U.S. officials who have been campaigning against using Kaspersky software on sensitive computers are likely to seize on the admission that the company took secret code that was not endangering its customer to justify a ban.

Fears about Kaspersky’s ties to Russian intelligence, and the capacity of its anti-virus software to sniff out and remove files, prompted an escalating series of warnings and actions from U.S. authorities over the past year. They culminated in the Department of Homeland Security last month barring government agencies from using Kaspersky products.

In a statement, the company said it stumbled on the code a year earlier than the recent newspaper reports had it, in 2014. It said logs showed that the consumer version of Kaspersky’s popular product had been analyzing questionable software from a U.S. computer and found a zip file that was flagged as malicious.

While reviewing the file’s contents, an analyst discovered it contained the source code for a hacking tool later attributed to what Kaspersky calls the Equation Group. The analyst reported the matter to Chief Executive Eugene Kaspersky, who ordered that the company’s copy of the code be destroyed, the company said.

“Following a request from the CEO, the archive was deleted from all our systems,” the company said. It said no third parties saw the code, though the media reports had said the spy tool had ended up in Russian government hands.

The Wall Street Journal said on Oct. 5 that hackers working for the Russian government appeared to have targeted the NSA worker by using Kaspersky software to identify classified files. The New York Times reported on Oct. 10 that Israeli officials reported the operation to the United States after they hacked into Kaspersky’s network.

Kaspersky did not say whether the computer belonged to an NSA worker who improperly took home secret files, which is what U.S. officials say happened. Kaspersky denied the Journal’s report that its programs searched for keywords including “top secret.”

The company said it found no evidence that it had been hacked by Russian spies or anyone except the Israelis, though it suggested others could have obtained the tools by hacking into the American’s computer through a back door it later spotted there.

The new 2014 date of the incident is intriguing, because Kaspersky only announced its discovery of an espionage campaign by the Equation Group in February 2015. At that time, Reuters cited former NSA employees who said that Equation Group was an NSA project.

Kaspersky’s Equation Group report was one of its most celebrated findings, since it indicated that the group could infect firmware on most computers. That gave the NSA almost undetectable presence.

Kaspersky later responded via email to a question by Reuters to confirm that the company had first discovered the so-called Equation Group programs in the spring of 2014.

It also did not say how often it takes uninfected, non-executable files, which normally would pose no threat, from users’ computers.

Former employees told Reuters in July that the company used that technique to help identify suspected hackers. A Kaspersky spokeswoman at the time did not explicitly deny the claim but complained generally about “false allegations.”

After that, the stories emerged suggesting that Kaspersky was a witting or unwitting partner in espionage against the United States.

Kaspersky’s consumer anti-virus software has won high marks from reviewers.

It said Monday that it would submit the source code of its software and future updates for inspection by independent parties.

Senators push bill requiring warrant for U.S. data under spy law

Senators push bill requiring warrant for U.S. data under spy law

By Dustin Volz

WASHINGTON (Reuters) – A bipartisan group of at least 10 U.S. senators plans to introduce on Tuesday legislation that would substantially reform aspects of the National Security Agency’s warrantless internet surveillance program, according to congressional aides.

The effort, led by Democrat Ron Wyden and Republican Rand Paul, would require a warrant for queries of data belonging to any American collected under the program. The bill’s introduction is likely to add uncertainty to how Congress will renew a controversial portion of a spying law due to expire on Dec. 31.

Section 702 of the Foreign Intelligence Surveillance Act is considered by U.S. intelligence officials to be among their most vital tools used to combat national and cyber security threats and help protect American allies.

It allows U.S. intelligence agencies to eavesdrop on and store vast amounts of digital communications from foreign suspects living outside the United States.

The surveillance program, classified details of which were exposed in 2013 by former NSA contractor Edward Snowden, also incidentally scoops up communications of Americans, including if they communicate with a foreign target living overseas.

Those communications can then be subject to searches without a warrant, including by the Federal Bureau of Investigation, a practice that the USA Rights Act authored by Wyden and Paul would end.

The measure is expected to be introduced with support from a wide berth of civil society groups, including the American Civil Liberties Union and FreedomWorks, a Wyden spokesman said.

It would renew Section 702 for four years with additional transparency and oversight provisions, such as allowing individuals to more easily raise legal challenges against the law and expand the oversight jurisdiction of the Privacy and Civil Liberties Oversight Board, a government privacy watchdog.

A bipartisan group of lawmakers in the House of Representatives earlier this month introduced legislation seeking to add privacy protections to Section 702, including a partial restriction to the FBI’s ability to access U.S. data when seeking evidence of a crime.

But that was criticized by privacy groups as too narrow.

Separately, the Senate Intelligence Committee is expected to privately vote on Tuesday on a bill to reauthorize Section 702 that privacy advocates say will lack their reform priorities.

Wyden sent a letter on Monday urging committee leaders to allow a public vote, saying the bill “will have enormous impact on the security, liberty, and constitutional rights of the American people” and should be debated in the open.

U.S. lawmakers want to restrict internet surveillance on Americans

U.S. lawmakers want to restrict internet surveillance on Americans

By Dustin Volz

(Reuters) – A bipartisan group of U.S. lawmakers unveiled legislation on Wednesday that would overhaul aspects of the National Security Agency’s warrantless internet surveillance program in an effort to install additional privacy protections.

The bill, which will be formally introduced as soon as Thursday, is likely to revive debate in Washington over the balance between security and privacy, amid concerns among some lawmakers in both parties that the U.S. government may be too eager to spy on its own citizens.

The legislation, written by the House of Representatives Judiciary Committee, is seen by civil liberties groups as the best chance in Congress to reform the law, known as Section 702 of the Foreign Intelligence Surveillance Act, before its expiration on Dec. 31.

Senior U.S. intelligence officials consider Section 702 to be among the most vital tools they have to thwart threats to national security and American allies.

It allows U.S. intelligence agencies to eavesdrop on and store vast amounts of digital communications from foreign suspects living outside the United States.

But the program, classified details of which were exposed in 2013 by former NSA contractor Edward Snowden, also incidentally scoops up communications of Americans, including if they communicate with a foreign target living overseas. Those communications can then be subject to searches without a warrant by the Federal Bureau of Investigation.

A discussion draft of the legislation, a copy of which was seen by Reuters, partially restricts the FBI’s ability to access American data collected under Section 702 by requiring the agency to obtain a warrant when seeking evidence of a crime.

That limit would not apply, however, to requests of data that involve counterterrorism or counter-espionage.

The narrower restriction on what some have called a “backdoor search loophole” has disappointed some civil liberties groups. Several organizations sent a letter this week saying they would not support legislation that did not require a warrant for all queries of American data collected under Section 702.

The legislation would also renew the program for six years and codify the National Security Agency’s decision earlier this year to halt the collection of communications that merely mentioned a foreign intelligence target. But that codification would end in six years as well, meaning NSA could potentially resume the activity in 2023.

The spy agency has said it lost some operational capability by ending so-called “about” collection due to privacy compliance issues and has lobbied against a law that would make its termination permanent.

Republican senators introduced a bill earlier this year to renew Section 702 without changes and make it permanent, a position backed by the White House and intelligence agencies.

But that effort is expected to face major resistance in the House, where an influential conservative bloc of Republicans earlier this year said it opposed renewal unless major changes were made, reflecting disagreement within the majority party.

Separately, Senators John Cornyn, the No. 2 Republican in the chamber, and Democratic Senator Dianne Feinstein are working on Section 702 legislation that may also be introduced this week and include fewer reforms.

Democratic Senator Ron Wyden and Republican Senator Rand Paul are also planning to introduce a bill that would require a warrant for any query of Section 702 involving data belonging to an American.

NSA says it would need to scale down spying program ahead of expiration

By Dustin Volz

WASHINGTON (Reuters) – The U.S. National Security Agency would need to begin winding down what it considers its most valuable intelligence program before its expiration at year-end if the U.S. Congress leaves its reauthorization in limbo, the agency’s deputy director said on Friday.

The possibility the U.S. government may begin losing access to the surveillance authority even before it would officially lapse on Dec. 31 is likely to increase pressure on lawmakers to quickly renew the law.

“We would have to be looking to work with our mission partners in the government as well as the companies to start scaling down in advance,” George Barnes, the deputy director of the NSA, said at the George Washington University Center for Cyber & Homeland Security event.

“We would, definitely. The last thing we would want to do is conduct any operation … if we did not have an active statute in place,” Barnes said in response to a question asked by Reuters. “We would have to work the dates backwards to make sure we didn’t cross the line.”

Asked about the remarks by Barnes, an NSA spokesman said the agency fully expects Congress to reauthorize the program.

The law, Section 702 of the Foreign Intelligence Surveillance Act, allows U.S. intelligence agencies to eavesdrop on, and store vast amounts of, digital communications from foreign suspects living outside of the United States.

It is considered a critical national security tool by U.S. officials, who say it supports priorities ranging from counterterrorism to cyber security.

But the program, classified details of which were exposed by 2013 by former NSA contractor Edward Snowden, also incidentally scoops up communications of Americans for a variety of technical reasons, including if they communicate with a foreign target living overseas. Those communications can then be subject to searches from analysts without a warrant.

The scenario articulated by Barnes resembles one that occurred two years ago, when portions of a separate law, the Patriot Act, that allowed the NSA to collect bulk domestic phone metadata were expiring.

Gridlocked over whether to enact reforms, U.S. lawmakers briefly let that Patriot Act lapse. The NSA said it had to begin winding down the program about a week before its expiration.

A bipartisan group of lawmakers in Congress is working on legislation to reform aspects of Section 702, but many Republicans, supported by the White House, want to renew the law without changes and make it permanent.

NSA backtracks on sharing number of Americans caught in warrant-less spying

By Dustin Volz

WASHINGTON (Reuters) – For more than a year, U.S. intelligence officials reassured lawmakers they were working to calculate and reveal roughly how many Americans have their digital communications vacuumed up under a warrant-less surveillance law intended to target foreigners overseas.

This week, the Trump administration backtracked, catching lawmakers off guard and alarming civil liberties advocates who say it is critical to know as Congress weighs changes to a law expiring at the end of the year that permits some of the National Security Agency’s most sweeping espionage.

“The NSA has made Herculean, extensive efforts to devise a counting strategy that would be accurate,” Dan Coats, a career Republican politician appointed by Republican President Donald Trump as the top U.S. intelligence official, testified to a Senate panel on Wednesday.

Coats said “it remains infeasible to generate an exact, accurate, meaningful, and responsive methodology that can count how often a U.S. person’s communications may be collected” under the law known as Section 702 of the Foreign Intelligence Surveillance Act.

He told the Senate Intelligence Committee that even if he dedicated more resources the NSA would not be able to calculate an estimate, which privacy experts have said could be in the millions.

The statement ran counter to what senior intelligence officials had previously promised both publicly and in private briefings during the previous administration of President Barack Obama, a Democrat, lawmakers and congressional staffers working on drafting reforms to Section 702 said.

Representative John Conyers, the top Democrat in the House of Representatives Judiciary Committee, said that for many months intelligence agencies “expressly promised” members of both parties to deliver the estimated number to them.

Senior intelligence officials had also previously said an estimate could be delivered. In March, then NSA deputy director Rick Ledgett, said “yes” when asked by a Reuters reporter if an estimate would be provided this year.

“We’re working on that with the Congress and we’ll come to a satisfactory resolution, because we have to,” said Ledgett, who has since retired from public service.

The law allows U.S. intelligence agencies to eavesdrop on and collect vast amounts of digital communications from foreign suspects living outside of the United States, but often incidentally scoops up communications of Americans.

The decision to scrap the estimate is likely to complicate a debate in Congress over whether to curtail certain aspects of the surveillance law, congressional aides said. Congress must vote to renew Section 702 to avoid its expiration on Dec. 31.

Privacy issues often scramble traditional party lines, but there are signs that Section 702’s renewal will be even more politically unpredictable.

Some Republicans who usually support surveillance programs have expressed concerns about Section 702, in part because they are worried about leaks of intercepts of conversations between Trump associates and Russian officials amid investigations of possible collusion.

U.S. intelligence agencies last year accused Russia of interfering in the 2016 presidential election campaign, allegations Moscow denies. Trump denies there was collusion. Intelligence officials have said Section 702 was not directly connected to surveillance related to those leaks.

“As big a fan as I am of collection, incidental collection, I’m not going to reauthorize a program that could be politically manipulated,” Senator Lindsey Graham, usually a defender of U.S. surveillance activities, told reporters this week.

Graham was among 14 Republican senators, including every Republican member of the intelligence panel, who on Tuesday introduced a bill supported by the White House and top intelligence chiefs, that would renew Section 702 without changes and make it permanent.

Critics have called the process under which the FBI and other agencies can query the pool of data collected for U.S. information a “backdoor search loophole” that evades traditional warrant requirements.

“How can we accept the government’s reassurance that our privacy is being protected when the government itself has no idea how many Americans’ communications are being swept up and stored?” said Liza Goitein, a privacy expert at the Brennan Center for Justice.

NSA collected Americans’ phone records despite law change: report

An illustration picture shows the logo of the U.S. National Security Agency on the display of an iPhone in Berlin, June 7, 2013. REUTERS/Pawel Kopczynski

By Mark Hosenball

WASHINGTON (Reuters) – The U.S. National Security Agency collected more than 151 million records of Americans’ phone calls last year, even after Congress limited its ability to collect bulk phone records, according to an annual report issued on Tuesday by the top U.S. intelligence officer.

The report from the office of Director of National Intelligence Dan Coats was the first measure of the effects of the 2015 USA Freedom Act, which limited the NSA to collecting phone records and contacts of people U.S. and allied intelligence agencies suspect may have ties to terrorism.

It found that the NSA collected the 151 million records even though it had warrants from the secret Foreign Intelligence Surveillance court to spy on only 42 terrorism suspects in 2016, in addition to a handful identified the previous year.

The NSA has been gathering a vast quantity of telephone “metadata,” records of callers’ and recipients’ phone numbers and the times and durations of the calls – but not their content – since the September 11, 2001, attacks.

The report came as Congress faced a decision on whether to reauthorize Section 702 of the Foreign Intelligence Surveillance Act (FISA), which permits the NSA to collect foreign intelligence information on non-U.S. persons outside the United States, and is scheduled to expire at the end of this year.

Privacy advocates have argued that Section 702 permits the NSA to spy on Internet and telephone communications of Americans without warrants from the secret Foreign Intelligence Surveillance Court, and that foreign intelligence could be used for domestic law enforcement purposes in a way that evades traditional legal requirements.

The report said that on one occasion in 2016, the FBI obtained information about an American in response to a search of Section 702 data intended to produce evidence of a crime not related to foreign intelligence.

The report did not address how frequently the FBI obtained information about Americans while investigating a foreign intelligence matter, however.

On Friday, the NSA said it had stopped a form of surveillance that allowed it to collect the digital communications of Americans who mentioned a foreign intelligence target in their messages without a warrant.

TRUMP’S ALLEGATIONS

The new report also came amid allegations, recently repeated by U.S. President Donald Trump, that former President Barack Obama ordered warrantless surveillance of his communications and that former national security adviser Susan Rice asked the NSA to unmask the names of U.S. persons caught in the surveillance.

Both Republican and Democratic members of the congressional intelligence committees have said that so far they have found no evidence to support either allegation.

Officials on Tuesday argued that the 151 million records collected last year were tiny compared with the number collected under procedures that were stopped after former NSA contractor Edward Snowden revealed the surveillance program in 2013.

Because the 151 million would include multiple calls made to or from the same phone numbers, the number of people whose records were collected also would be much smaller, the officials said. They said they had no breakdown of how many individuals’ phone records were among those collected.

In all, according to the report, U.S. officials unmasked the names of fewer Americans in NSA eavesdropping reports in 2016 than they did the previous year, the top U.S. intelligence officer reported on Tuesday.

The report said the names of 1,934 “U.S. persons” were “unmasked” last year in response to specific requests, compared with 2,232 in 2015, but it did not identify who requested the names or on what grounds.

Officials said in the report that U.S. intelligence agencies had gone out of their way to make public more information about U.S. electronic eavesdropping.

“This year’s report continues our trajectory toward greater transparency, providing additional statistics beyond what is required by law,” said Office of the Director of National Intelligence spokesman Timothy Barrett.
