Washington (CNN) Two Romanian hackers infiltrated nearly two-thirds of the outdoor surveillance cameras in Washington, DC, as part of an extortion scheme, according to federal court documents. 
  
 In a criminal complaint filed last week in the US District Court for the District of Columbia, the US government alleges that the two Romanian hackers operating outside the United States infiltrated 65% of the outdoor surveillance cameras operated by DC city police — that's 123 cameras out of 187 in the city. The alleged hacking occurred during a four-day period in early January. 
  
 The hacking suspects, Mihai Alexandru Isvanca and Eveline Cismaru, are also accused of using the computers behind the surveillance cameras to distribute ransomware through spam emails, according to an affidavit by Secret Service agent James Graham in support of the government's criminal complaint. The affidavit alleges the hackers meant to use the malware to lock victims' computers and then extort payments from them to regain access. 
  
 In the affidavit, the Romanians are accused of "intent to extort from persons money and other things of value, to transmit in interstate and foreign commerce communications containing threats to cause damage to protected computers." 
  
 They were traced through their registered email addresses, one of which roughly translates into "selling souls" in Romanian, according to the affidavit. ||||| Image copyright Getty Images Image caption Washington police security was compromised by a computer hack in January 
  
 US prosecutors have charged two Romanians with hacking Washington DC police computers linked to surveillance cameras just days before President Donald Trump's inauguration. 
  
 The pair are being held in Romania, having been arrested at Bucharest Otopeni airport on 15 December. 
  
 Mihai Alexandru Isvanca, 25, and Eveline Cismaru, 28, allegedly accessed 123 outdoor surveillance cameras as part of a suspected ransomware scheme. 
  
 Mr Trump was sworn in on 20 January. 
  
 The US Department of Justice said the case was "of the highest priority" because of the security surrounding the presidential inauguration. 
  
 The perpetrators intended to use the camera computers to send ransomware to more than 179,600 email addresses and extort money from victims, the justice department said in a statement. 
  
 Investigators have identified victims who had received the ransomware or whose computer servers had been accessed, it added.

 There was no evidence that the alleged hackers had physically harmed or threatened anyone, the US statement added. 
  
 A secret service agent, James Graham, said in an affidavit that two variants of "sophisticated, malicious computer code" had been placed on three police computers, one known as "cerber" and the other known as "dharma". 
  
 In ransomware attacks, malware is secretly installed on computers, usually via rogue email attachments, which locks programs. The hackers then demand payment in exchange for unlocking the computers.

 Mr Isvanca and Ms Cismaru are accused of conspiracy to commit wire fraud - that is, financial fraud using computers - which carries a maximum penalty of 20 years in jail.

 The EU police agency Europol says three other suspects were also arrested in Romania this month in a linked investigation into ransomware. The UK's National Crime Agency was involved in that investigation. 
  
 The three are suspected of infecting computers with CTB-Locker (Curve-Tor-Bitcoin Locker) malware. 
  
 A Europol statement says Romanian police were tipped off in early 2017 by the Dutch High Tech Crime Unit and other authorities about a group of Romanians sending spam messages. 
  
 The spam emails had attachments made to look as if they had come from well-known companies in Italy, the Netherlands and UK. Once opened on a Windows system, those malicious attachments encrypted computer files. |||||

Romanian hackers infiltrated 65% of outdoor surveillance cameras in Washington, DC, ahead of President Trump's inauguration as part of an extortion scheme only now being made public, according to a criminal complaint. The complaint, filed in DC and unsealed Thursday, accuses Romanians Mihai Alexandru Isvanca, 25, and Eveline Cismaru, 28, of hacking 123 of the city's 187 outdoor police cameras over four days in January 2017, leaving them temporarily unable to record footage, report CNN and the Washington Post. All the cameras were OK by the big day. An affidavit says the individuals—believed to be part of a hacking network—took over the computer system that operated the cameras and began sending ransomware emails to about 180,000 email addresses. Authorities say they planned to lock users out of their computers until they received payment. DC police first noticed a malfunction in the cameras on Jan. 12. A Secret Service agent then detected the hack. Authorities fixed the problem by taking the cameras offline, wiping them clean, and rebooting them by Jan. 15, five days ahead of Trump's inauguration. No ransom payments were made. "This case was of the highest priority due to its impact on the Secret Service's protective mission and its potential effect on the security plan for the 2017 Presidential Inauguration," a spokesman for US Attorney Jessie K. Liu says, per the Post. Isvanca and Cismaru were arrested in Bucharest on Dec. 15 along with three others who face charges in Europe, reports the BBC. Prosecutors plan to seek extradition for the pair soon. The Post notes that it's not clear the alleged hackers knew they had infiltrated a police computer system.
