FBI nabs man it says planned July 4 attacks on Cleveland, Philadelphia

Fireworks at Morningside 7-4-17

By Makini Brice

WASHINGTON (Reuters) – The FBI has arrested a man who it said planned to bomb Cleveland’s Fourth of July celebrations and then stand by and watch “it go off,” federal officials said on Monday.

Demetrius Pitts, 48, who had expressed allegiance to the al Qaeda militant group, was arrested on Sunday after a meeting with an undercover FBI agent where he said he planned to plant a bomb at a parade celebrating the U.S. Independence Day holiday and intended to target other locations in Cleveland and Philadelphia.

Many major American cities mark the holiday with fireworks and parades, and typically ramp up security around such events.

An undercover FBI agent helped Pitts pick the location for his planned attack, near a planned fireworks show and multiple U.S. government buildings, the FBI said.

“I’m gonna be downtown when the – when the thing go off. I’m gonna be somewhere cuz I wanna see it go off,” Pitts told an undercover FBI agent who he believed was affiliated with al Qaeda, the FBI said in court documents.

Pitts also suggested giving the children of military personnel remote control cars packed with explosives during the parade so the kids would unwittingly detonate the bombs, the FBI said.

Pitts was charged with attempting to provide material support to a designated foreign terrorist organization. He faces up to 20 years in prison if convicted.

An FBI source gave Pitts a bus pass and a phone to conduct surveillance ahead of his planned attack, prosecutors said.

Pitts, who lives in the Cleveland suburb of Maple Heights, also discussed possibly traveling to San Francisco for reconnaissance for al Qaeda, the FBI said.

It was not immediately clear if he had retained a lawyer, and relatives could not be reached for comment.

“This defendant, by his own words and by his own deeds, wanted to attack our nation and its ideals,” said Justin Herdman, the U.S. attorney for northern Ohio.

Officials said Pitts is an American citizen who had been radicalized in the United States.

In 2015, U.S. law enforcement officials said they had arrested more than 10 people inspired by the Islamic State militant group ahead of the Fourth of July holiday, saying the arrests had disrupted planned attacks.

A pair of ethnic Chechen brothers inspired by al Qaeda killed three people and injured more than 260 with a pair of homemade bombs at the Boston Marathon in 2013.

Glass ceiling for female federal investigators: U.S. watchdog report

By Sarah N. Lynch

WASHINGTON (Reuters) – Women are not getting hired or promoted at the same rate as men in the U.S. Justice Department’s top law enforcement arms, leaving many female employees feeling they face routine gender discrimination in the workplace, the department’s internal watchdog has found.

A report by Inspector General Michael Horowitz, issued on Tuesday, looked at gender equity issues across the FBI, the Drug Enforcement Administration, the Bureau of Alcohol, Tobacco, Firearms and Explosives, and the U.S. Marshals Service.

The low number of women in the ranks and the lack of promotions compared to their male counterparts is a large factor behind a perception of inequality that many women in the agencies have, the report found.

In fiscal year 2016, for instance, women comprised only 16 percent of the criminal investigator population across all four law enforcement agencies, it said.

And of the women employed, many worked in human resources or other administrative roles, and few held top leadership positions.

While a majority of male employees surveyed believed the workplace treated men and women equitably, a minority of women – only 33 percent – believed this was the case.

“We find it concerning that 22 percent of all women and 43 percent of female criminal investigators reported to us in the survey that they had been discriminated against based on their gender,” the report said.

“Additionally, in almost all the interviews and female focus groups we conducted, women reported to us that they had experienced some type of gender discrimination.”

Despite the fact many women reported being passed over for promotions or experiencing gender-based discrimination, few decided to file a formal Equal Employment Opportunity complaint.

Many of the women surveyed said they were concerned that filing a complaint might trigger retaliation, create a negative stigma or else they did not have confidence in the process.

“Underreporting and ineffective handling of EEO claims undermines employee trust and confidence that components (agencies) will address discriminatory behavior,” the report concluded.

The report calls on the Justice Department to take steps to improve how it hires, recruits and retains female employees.

All of the four agencies concurred with the watchdog’s recommendations.

FBI says foreign hackers have compromised home router devices

By Sarah N. Lynch

WASHINGTON (Reuters) – The FBI warned on Friday that foreign cyber criminals had compromised “hundreds of thousands” of home and small office router devices around the world which direct traffic on the internet by forwarding data packets between computer networks.

In a public service announcement, the FBI it has discovered that the foreign cyber criminals used a VPNFilter malware that can collect peoples’ information, exploit their devices and also block network traffic.

The announcement did not provide any details about where the criminals might be based, or what their motivations could be.

“The size and scope of the infrastructure by VPNFilter malware is significant,” the FBI said, adding that it is capable of rendering peoples’ routers “inoperable.”

It said the malware is hard to detect, due to encryption and other tactics.

The FBI urged people to reboot their devices to temporarily disrupt the malware and help identify infected devices.

People should also consider disabling remote management settings, changing passwords to replace them with more secure ones and upgrading to the latest firmware.

U.S. officials warn Congress on 2018 election hacking threats

U.S. Secretary of Homeland Security Kirstjen Nielsen speaks to reporters after she, FBI Director Christopher Wray and Director of National Intelligence Daniel Coats briefed members of the U.S. House of Representatives on election security at the U.S. Capitol in Washington, U.S., May 22, 2018.

By David Shepardson

WASHINGTON (Reuters) – Senior Trump administration officials warned Congress on Tuesday of ongoing efforts by Russia to interfere in the 2018 midterm congressional elections as the federal government prepares to hand out $380 million in election security funding to states.

At a briefing attended by about 40 or 50 members of the 435-member U.S. House of Representatives, the heads of FBI, Homeland Security Department and the director of National Intelligence said states and cities overseeing elections need to be prepared for threats.

DHS Secretary Kirstjen Nielsen told reporters she agreed Russia was trying to influence the 2018 elections.

“We see them continuing to conduct foreign influence campaigns,” Nielsen said, but added there is no evidence of Russia targeting specific races.

Nielsen said DHS is watching other countries that have the capability to influence U.S. elections, including China and Iran. “We need to be prepared,” she said.

Chris Krebs, a senior DHS cyber security official, told Reuters that the administration was sending states guidance on how to spend the $380 million approved by Congress in March to help safeguard U.S. voting systems from cyber attacks. The funds are expected to be distributed later this week.

DHS is assisting 48 states with election security. It handed out a chart at the briefing to members that said states need to have auditable systems, spend time on planning, training and drills and they should “consider investing in full system architecture reviews.”

Representative Michael McCaul, who chairs the House Homeland Security Committee, said after the briefing that members are concerned that “not only Russia but possibly other foreign adversaries are now going to start looking at how they can meddle in the midterm elections and we need to be prepared. We were caught off guard last time.”

U.S. intelligence agencies have concluded that Russian leadership at a very high level was involved in the attempt to interfere in the U.S. election in order to boost President Donald Trump’s candidacy.

Russia has denied interfering in U.S. elections.

Several Democrats after the briefing expressed concern that the federal government was not doing enough to safeguard elections.

“It is clear that our government must do more and whatever possible to secure our elections from foreign interference. The integrity of our democracy is at stake,” said Representative Bennie Thompson, the top Democrat on the Homeland Security Committee.

UNPRECEDENTED, COORDINATED

A May 8 U.S. Senate report said that in 2016 “cyber actors affiliated with the Russian Government conducted an unprecedented, coordinated cyber campaign against state election infrastructure.” Russian actors “scanned databases for vulnerabilities, attempted intrusions, and in a small number of cases successfully penetrated a voter registration database.”

The report said in a small number of states, “these cyber actors were in a position to, at a minimum, alter or delete voter registration data.”

Krebs said on Tuesday that DHS wanted states to “increase awareness” and have a “layered defense.”

If a voter’s information was missing, for example, they could request a provisional ballot. “If we do detect something, we can overcome it,” he said.

During the 2016 campaign, hackers stole emails from the personal account of Democratic candidate Hillary Clinton’s campaign chairman and from the Democratic National Committee, and they were used to embarrass Clinton.

Representative C.A. “Dutch” Ruppersberger, said members of Congress need to be aware of cyber risks. “We need to focus on it, make it a priority,” he said.

DHS said in March it is prioritizing election cyber security above all other critical infrastructure it protects.

The agency has said that 21 states had experienced initial probing of their systems from Russian hackers in 2016 and that a small number of networks were compromised, but that there remains no evidence any votes were actually altered.

Representative Adam Schiff, the top Democrat on the Intelligence Committee, told reporters the federal government should quickly alert states if they learn of election system hacking.

He also wants a “real-time communications channel” between the intelligence community and technology companies in order to assure that internet firms are notified if evidence emerges that Russia is creating fake Facebook Inc <FB.O> pages or taking other actions to influence the elections.

U.S. investigating Cambridge Analytica: New York Times

WASHINGTON (Reuters) – The U.S. Justice Department and the FBI are investigating Cambridge Analytica, a now-defunct political data firm embroiled in a scandal over its handling of Facebook Inc user information, the New York Times reported on Tuesday.

Prosecutors have sought to question former Cambridge Analytica employees and banks that handled its business, the newspaper said, citing an American official and others familiar with the inquiry,

Cambridge Analytica said earlier this month it was shutting down after losing clients and facing mounting legal fees resulting from reports the company harvested personal data about millions of Facebook users beginning in 2014.

Allegations of the improper use of data for 87 million Facebook users by Cambridge Analytica, which was hired by President Donald Trump’s 2016 U.S. election campaign, have prompted multiple investigations in the United States and Europe.

The investigation by the Justice Department and FBI appears to focus on the company’s financial dealings and how it acquired and used personal data pulled from Facebook and other sources, the Times said.

Investigators have contacted Facebook, according to the newspaper.

The FBI, the Justice Department and Facebook declined to comment to Reuters. Former officials with Cambridge Analytica was not immediately available to comment.

Cambridge Analytica was created around 2013, initially with a focus on U.S. elections, with $15 million in backing from billionaire Republican donor Robert Mercer and a name chosen by future Trump White House adviser Steve Bannon, the New York Times has reported. Bannon left the White House on August 2017.

Man arrested in wave of package bombs in Washington, D.C

WASHINGTON (Reuters) – A Washington state man has been arrested in connection with a series of package bombs sent to U.S. military installations and a CIA mail office in the Washington, D.C., area earlier this week, the FBI said on Tuesday.

The suspect, Thanh Cong Phan, 43, was arrested on Monday at his home in Everett, Washington, by federal agents and sheriff’s deputies, the Federal Bureau of Investigation said in a statement.

A U.S. security official said Phan had a history of writing incoherent letters to government officials and was believed to have mental problems. The official declined to be named during an ongoing investigation.

Court documents made public on Tuesday afternoon showed that Phan had been charged in U.S. District Court in Seattle with one count of shipping explosive materials.

Suspicious packages were received on Monday at mail processing sites at Fort Belvoir, Virginia; Joint Base Anacostia-Bolling, which is a Navy-Air Force facility in the District of Columbia; and Fort Lesley J. McNair in the U.S. capital, the agency said.

The packages also turned up at mail facilities at the Naval Surface Warfare Center in Dahlgren, Virginia, and the Central Intelligence Agency in Langley, Virginia. None of them detonated.

“It is possible that further packages were mailed to additional mail processing facilities in the Washington, D.C., metropolitan area,” the FBI said. The packages were being analyzed at the FBI laboratory at Quantico, Virginia.

Ashwin Cattamanchi, a federal public defender representing Phan, declined to comment when reached by phone.

Officials at Fort McNair evacuated a building after one of the packages was delivered, a spokesman said. An Army bomb squad confirmed that the package tested positive for explosive residue and determined a fuse was attached, he said.

Earlier in March in a separate incident at a U.S. military base, a man died after driving a minivan through the gate of Travis Air Force Base in California and igniting propane tanks and gasoline cans.

Several package bombs left on doorsteps and some sent from a Federal Express office detonated in Austin, Texas, leaving two people dead and others injured. The suspected bomber blew himself up as police closed in on him.

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.

Judge denies motion to drop case against widow of Orlando gunman

By Joey Roulette

ORLANDO, Fla. (Reuters) – A judge on Monday denied a defense motion to dismiss charges against the widow of the gunman in the 2016 massacre at Orlando’s Pulse nightclub, saying that the gunman’s father’s work an FBI informant was not relevant to the case.

Over the weekend, prosecutors disclosed that Omar Mateen’s father, Seddique, had worked with the Federal Bureau of Investigation before his son carried out the massacre of 49 people at the Pulse nightclub in June 2016.

In opening their case, lawyers for Mateen’s widow, Noor Salman, argued that the judge should dismiss the charges against her or declare a mistrial because prosecutors had failed to reveal the FBI’s relationship to Mateen’s father and other evidence related to him beforehand.

Salman, 31, is accused of helping her husband carry out surveillance of possible attack sites and doing nothing to stop him. Mateen, a U.S. citizen of Afghan descent who claimed allegiance to a member of the Islamic State militant group, was killed by police after more than three hours in the Pulse nightclub.

An FBI agent on Monday testified that years before Mateen carried out the attack, the agency considered using him as an informant, like his father.

Those discussions took place while the FBI was investigating comments made by the younger Mateen about overseas links to militants, Special Agent Juvenal Martin said in federal court in Orlando. That investigation closed without charges, he said.

Martin did not say why the FBI decided against enlisting Omar Mateen as an informant.

Salman’s attorneys say that the disclosure by prosecutors that Seddique Mateen had been an informant from January 2005 to June 2016 violated a Supreme Court ruling barring prosecutors from withholding evidence.

After resting their case, prosecutors said agents probing the nightclub rampage found receipts of money transfers made from the United States to Turkey and Afghanistan made by the elder Mateen. An active investigation was under way, they said.

If the defense had known about the transfers, it would have investigated whether Seddique Mateen was involved in the attack or had prior knowledge of it, Fritz Scheller, a lawyer for Salman, said in the motion to dismiss.

But U.S. District Judge Paul Byron said, “It is not clear whether the purpose of the transfers was illegal.”

He said the omission of any evidence related to Seddique Mateen had no bearing on the culpability of Salman.

Salman faces possible life in prison if convicted on charges of aiding her husband in the attack and obstructing an investigation.

U.S. spending bill tackles border, election security: source

WASHINGTON (Reuters) – A federal government spending deal being worked out in the U.S. Congress includes additional funding to boost border security, protect the upcoming elections in November and rebuild aging infrastructure, a source familiar with the negotiations said on Wednesday.

While the source said a final overall spending agreement had not been reached, other Republican and Democratic congressional aides have told Reuters that leaders plan to unveil their agreement on the $1.3 trillion spending bill later on Wednesday.

Lawmakers in the Republican-controlled Congress have until Friday night to reach a deal before a lapse would force federal agencies to suspend operations. The current plan would provide for government funding through Sept. 30, after a series of short-term funding measures implemented since last fall.

Republican leaders in the House and Senate said on Tuesday they were close to a deal and hoped to complete legislation by Friday as they worked to overcome divisions over several thorny issues such as President Donald Trump’s proposed border wall.

So far, the package provides $1.6 billion for some fencing along the U.S. border with Mexico and other technological border security efforts, the source said.

Trump had sought $25 billion for a full wall, but negotiations fell through to provide more money in exchange for protections for “Dreamers,” young adults who were brought illegally into the United States as children.

The spending plan also provides $307 million more than the Trump administration’s request for the FBI to counter Russian cyber attacks, and $380 million for U.S. states to improve their technology before November’s congressional election, according to the source.

U.S. intelligence agencies have concluded that Russia sought to meddle in the 2016 presidential election campaign, and intelligence chiefs said last month that Russia will seek to interfere in the midterm elections this year by using social media to spread propaganda and misleading reports. Russia has denied any interference.

The planned spending measure allocates $10 billion for spending on infrastructure such as highways, airports and railroads. It also includes money for the so-called Gateway rail tunnel connecting New York and New Jersey, the source said.

Trump has threatened to veto the bill if the Gateway project is included. While its funds remain, they are directed through the U.S. Department of Transportation, rather than provided directly, Politico reported.

Additionally, lawmakers’ added $2.8 billion to address opioid addiction, the source said.

One potential stumbling block includes gun-related provisions prompted by a mass shooting at a Florida high school on Feb. 14 that killed 17 students and faculty members. On Tuesday, as another shooting swept over a high school in Maryland, House Speaker Paul Ryan said lawmakers were still discussing a proposal to improve federal background checks for gun purchases.

Another issue tying up negotiations was tax treatment for grain co-ops versus corporate producers, according to Politico.

Fifth package bomb strikes Texas, at FedEx facility near San Antonio

AUSTIN/SCHERTZ, Texas (Reuters) – A package bomb blew up at a FedEx Corp distribution center near San Antonio on Tuesday, officials said, and the FBI was investigating whether it was linked to a series of four homemade bombs that hit the Texas capital of Austin this month.

Officials did not say if the latest incident was the work of what Austin police believe could be a serial bomber responsible for the four earlier devices that killed two people and injured four others.

The blast at the FedEx facility in Schertz, northeast of San Antonio, was the fifth in the state in the last 18 days. If it is linked to the others, it would be the first outside the Austin area and the first that involves a commercial parcel service.

“We are investigating it as being possibly related to our open investigation,” FBI spokeswoman Michelle Lee told the Austin American-Statesman newspaper. “We can’t know for sure until we have an opportunity to look at the evidence itself.”

The package, filled with nails and metal shrapnel, exploded shortly after midnight local time at the facility, about 65 miles south of Austin, the San Antonio Fire Department said on Twitter.

The company described it as a FedEx Ground sorting facility. About 75 people were working at the facility at the time, fire officials said.

The individual or people behind the bombings are likely to be highly skilled and methodical, said Fred Burton, chief security officer for Stratfor, a private intelligence and security consulting firm based in Austin.

“This is a race against time to find him before he bombs again,” Burton said.

More than 500 federal agents were involved in the investigation.

Austin Mayor Steve Adler on Tuesday sought to reassure citizens. “While the concern is real and the anxiety is real … it can’t immobilize us. It has to make us more determined. It has to make us more vigilant,” he told a local television station.

The White House is monitoring the situation, spokeswoman Sarah Sanders told Fox News on Tuesday.

Further stoking fears, Austin police investigated a possible hazardous materials incident at a FedEx facility in Austin on Tuesday morning. There was no indication it was related to the bombings.

The first three devices were parcel bombs dropped off in front of homes on in three eastern Austin neighborhoods. The fourth went off on Sunday night on the west side of the city and was described by police as a more sophisticated device detonated through a trip wire mechanism.

The four devices were similar in construction, suggesting they were the work of the same bomb maker, officials said.

The first two bombs killed Anthony Stephan House, a 39-year-old black man on March 2 and Draylen Mason, a 17-year-old African-American teenager on March 12. The third, also on March 12, severely injured a 75-year-old Hispanic woman. Police said they are investigating whether the bombings were hate crimes.

Sunday’s trip wire bomb, which injured two white men, went off shortly after police made a rare public call to the suspect to explain his motives.

Austin, with a population of nearly 1 million people, is home to the University of Texas and a plethora of technology companies and has been one of the fastest growing major U.S. cities.
