[UPDATE: Reuters reported late today that its sources say Hillary Clinton's campaign website also was breached as part of what was a broad attack campaign against the Democratic party]
First the Democratic National Committe (DNC), and now this: A cyber espionage group apparently affiliated with pro-Russian causes earlier this year hacked into a donor website of the Democratic Congressional Campaign Committee (DCCC), the campaign arm of House Democrats.
The website was altered so visitors attempting to donate at the site were redirected instead to another domain controlled by the attackers, security vendor FireEye said in a report released yesterday. By the time FireEye discovered the intrusion earlier this week, the link to the malicious website had been disabled.
It's unclear if those who were redirected to the attacker-controlled site had their personal and financial data stolen or had malware dropped on their systems. It is also unclear how long visitors to the site were redirected, but it included a period between June 19 and June 27. “The site may have also been compromised for periods before and after those dates,” FireEye said.
News of the DCCC website intrusions follows the recent disclosure of an intrusion into a Democratic National Committee (DNC) system that resulted in thousands of internal emails being leaked and published on WikiLeaks. Controversial content in some of the purloined emails later forced the chairman of the DNC Debbie Wasserman Schultz to resign from her post and fueled angry accusations from the Democratic party about Russian interference in the US election process.
In comments to various media outlets, a spokesman for the Russian embassy in Washington denied any involvement in the DNC intrusion. But speculation of the source and motive for the attack continue to rage on, especially after the FBI this week said its analysis shows a potential Russian connection.
John Hultquist, manager cyber espionage intelligence at FireEye, says his firm discovered the intrusion at the DCCC website from its tracking of a cyber espionage group called Tsar Team, aka APT28. The group has been actively involved for the past three- or four years in a wide range of spying activities directed largely against Chechen rebels, Russian dissidents, and individuals with ties to the defense industry in multiple countries.
“There is all kinds of evidence that indicate they have a strong interest in Russian geopolitical and Russian security issues,” Hultquist says. “That is why we have been so focused on them.”
Interestingly, the Tsar Team’s activities have not been restricted solely to espionage activities. The group has also engaged in quite a bit of hacktivism, and recently it has resorted to fabricating persona with interests in different causes. For instance, the hacking team created a group called the Cyber Caliphate and has been using that to post pro-ISIS propaganda in an apparent bid to gain access to ISIS sympathizers, Hultquist says.
It was while looking for activity and traces of the unique malware associated with APT28 on the Web that FireEye discovered the intrusion at the DCCC website, he says. The company informed the DCCC about its discovery on Thursday.
In comments to Bloomberg, Meredith Kelly, press secretary for the DCCC, confirmed that the organization had been the victim of a cyber intrusion and was currently cooperating with law enforcement to investigate the issue. Kelly did not offer any other details of the breach.
