Input: NEW YORK (Reuters) - A group of hackers linked to Islamic State has posted online a list of thousands of New York residents and urged followers of the militant group to target them, according to a source with knowledge of the matter. 
  
 Federal agents and New York City police officers have been contacting the individuals on the list to inform them of the posting, but the source said law enforcement does not believe there is any credible threat. 
  
 In a statement, the Federal Bureau of Investigation said, “While our standard practice is to decline comment on specific operational and investigative matters, the FBI routinely notifies individuals and organizations of information collected during the course of an investigation that may be perceived as potentially threatening in nature.” 
  
 The list includes names, home addresses and email addresses. Some of the information appears to be outdated, according to the source, who was not authorized to discuss the investigation publicly. 
  
 Last year, an Islamic State-related group posted what it claimed were names, addresses and photos of 100 U.S. military service members and called upon followers to kill them. 
  
 The militant group controls swaths of territory in Syria and Iraq and has claimed responsibility for several major attacks in various countries, including coordinated attacks in Paris in November that killed 130 people. 
  
 U.S. authorities have arrested more than 70 individuals for attempting to support Islamic State since 2013. ||||| NEW YORK, April 29 (UPI) -- Some 3,000 New York City-area residents, most of them private citizens with no government ties, were targeted in an Islamic State "hit list," law enforcement said. 
  
 The list, intended as a threat, contains as many as 3,600 names. It includes some employees with the State Department and Homeland Security, but mostly contains personal information from private citizens. It was posted on site accessible to only IS supporters and is being considered a scare campaign from the IS-related group Caliphate Cyber United. 
  
 Law enforcement authorities said there is no specific threat to any one person or group. The FBI and New York Police Department plan to visit the homes of those targeted. The FBI said it would not comment on the incident specifically, but "the FBI routinely notifies individuals and organizations of information collected during the course of an investigation that may be perceived as potentially threatening in nature." 
  
 "Potential threats may relate to individuals, institutions or organizations and are shared in order to sensitize potential victims to the observed threat, and to assist them in taking proper steps to ensure their safety," FBI spokeswoman Carol Cratty said.

 ISIS-linked hackers have targeted about 3,000 ordinary New Yorkers in a cyberattack, posting their personal information online and announcing, "We want them #Dead," the I-Team has learned. 
  
 One of the victims, an 88-year-old man named Art -- whose last name is being withheld for privacy concerns -- spoke with the I-Team exclusively Thursday, telling of how the FBI visited and told him that his name was on the list posted Sunday on the private channel of a pro-ISIS group called the United Cyber Caliphate. 
  
 The FBI told him to be cautious when he goes out in public and to call 911 immediately if he felt threatened. 
  
 Still, Art said he is not overly concerned for his safety. 
  
 ISIS-Linked Hackers Target 3,000 New Yorkers in Cyberattack: Officials

 "It sounds like psychological warfare," he said. "Make 3,000 people in this city very upset." 
  
 FBI and NYPD officials plan to visit the homes of everyone targeted, but say there is no specific threat of violence against them. 
  
 An FBI spokeswoman said in a statement, "While our standard practice is to decline comment on specific operational and investigative matters, the FBI routinely notifies individuals and organizations of information collected during the course of an investigation that may be perceived as potentially threatening in nature.

 Locations of ordinary New Yorkers targeted in ISIS-linked cyberattack 
  
  
  
 NBC News terror analyst Laith Alkhouri recently released a report on increasing efforts by pro-ISIS groups to undertake cyberattacks. Last month, a pro-ISIS group hacked into the New Jersey Transit Police website and posted the personal information of officers there. Earlier this week, the same group released what they said was the personal information of some State Department personnel. 
  
 Alkhouri said the hackers' aim is to spread fear, and increase ISIS’ notoriety. 
  
 In this case, Alkhouri said the information was posted to a channel accessible only to certain ISIS supporters. It was posted only for a short time, then taken down, he said. He said it is likely the pro-ISIS group posts this way because releasing it more publicly would make them easier for law enforcement to track. And the group knows the information will get out to the public anyway, he said. 
  
 “What those guys are really trying to do is gain a lot of notoriety by saying we hacked American servers,” he told the I-Team. 
  
 Alkhouri said it’s not clear where the pro-ISIS group got the information of the 3,000 people it targeted. Many were from Brooklyn, and some from Manhattan, Staten Island, Queens and other surrounding areas. He said the people in the group did not appear to be politically active or government-affiliated. Like Art, they were mostly just ordinary New Yorkers. 
  
 He said so far the attacks aren’t sophisticated, but the group is trying to get more advanced in its attacks and recruiting efforts. 
  
 "These guys are trying to advance their capability, they’re trying to advance their skill set, and they’re trying to zoom in on more critical targets," he said. 
  
 Ken Maxwell, who once headed the FBI Joint Terrorism Task Force, says law enforcement has to take these kinds of threats seriously– but residents should go about their lives.

 That’s something Art says he plans to do. 
  
 "I’m not going to change my life, I’m not going to let this get me down," he said. "I’m not going to even do what they’re saying be cautious in the street, because it’s nonsense, it's nonsense." |||||
Output:
Hackers affiliated with ISIS posted the names of thousands of New York City residents online Sunday with the message "We want them #Dead," NBC New York reports. According to Reuters, the list contains home and email addresses. The "hit list" includes up to 3,600 New Yorkers, UPI reports. A few are State Department and Homeland Security employees, but most are regular citizens with no connection to the government. In fact, most don't even seem to be politically active. One such regular New Yorker is 88-year-old Art, who tells NBC he's not too worried despite a visit from the FBI. "It sounds like psychological warfare," he says. "Make 3,000 people in this city very upset." Authorities seem to agree with Art on that. While the FBI and police are notifying residents named on the list, they say they don't believe there is any credible or specific threat to anyone. The FBI states it "routinely notifies individuals and organizations of information collected during the course of an investigation that may be perceived as potentially threatening in nature." Authorities believe the list is simply a "scare campaign" from hacker group Caliphate Cyber United. It's unclear where the group got the names and addresses. ISIS and affiliated groups have previously released similar "kill lists" targeting prominent Muslim-Americans, members of the US military, and Minnesota police.
