FBI agents are investigating possible cyber attacks on the Democratic National Committee and Hillary Clinton campaign as the FBI’s investigation of the Democratic presidential nominee’s private email server continues.
A cybersecurity firm hired by the FBI said it had discovered the DNC server had been compromised on Thursday.
A statement on the cybersecurity firm’s website said it has been “surprised by a series of suspicious activity” including attempts to take control of the DNC’s network, as well as a denial of service attack on the DNC website that left it down for several hours on Friday.
The firm said the attacks appeared to have been launched by a Russian entity called Kaspersky Lab, and it was working with the FBI to determine how the attacks had been launched.
Kaspersky’s statement said it was also working with federal law enforcement authorities to determine whether any other Russian-based entities were involved in the attacks.
The FBI’s cyber unit is investigating whether the cyber attacks are part of a wider effort to influence the election.
The FBI has been investigating the possibility of Russian interference in the 2016 U.S. presidential election.
