PARIS (AP) - The same Russian government-aligned hackers who penetrated the Democratic Party have spent the past few months laying the groundwork for an espionage campaign against the U.S. Senate, a cybersecurity firm said Friday.
The revelation suggests the group often nicknamed Fancy Bear, whose hacking campaign scrambled the 2016 U.S. electoral contest, is still busy trying to gather the emails of America’s political elite.
“They’re still very active - in making preparations at least - to influence public opinion again,” said Feike Hacquebord, a security researcher at Trend Micro Inc., which published the report . “They are looking for information they might leak later.”
The Senate Sergeant at Arms office, which is responsible for the upper house’s security, declined to comment.
Hacquebord said he based his report on the discovery of a clutch of suspicious-looking websites dressed up to look like the U.S. Senate’s internal email system. He then cross-referenced digital fingerprints associated with those sites to ones used almost exclusively by Fancy Bear, which his Tokyo-based firm dubs “Pawn Storm.”
Trend Micro previously drew international attention when it used an identical technique to uncover a set of decoy websites apparently set up to harvest emails from the French presidential candidate Emmanuel Macron’s campaign in April 2017. The sites’ discovery was followed two months later by a still-unexplained publication of private emails from several Macron staffers in the final days of the race.
Hacquebord said the rogue Senate sites - which were set up in June and September of 2017 - matched their French counterparts.
“That is exactly the way they attacked the Macron campaign in France,” he said.
Attribution is extremely tricky in the world of cybersecurity, where hackers routinely use misdirection and red herrings to fool their adversaries. But Tend Micro, which has followed Fancy Bear for years, said there could be no doubt.
