The legal complaint—part of the DNC’s ongoing lawsuit against Russia, WikiLeaks, the Trump campaign, Russian operatives, and other Trump associates in connection to the 2016 hacking of DNC computers—said there is no evidence that the attempted hack in November 2018 was successful.

For those who came in late, the last presidential election was won in part because of a scandal over DMC emails which were made available by Russian hackers. It seems that the Russians thought the scheme worked so well they would try it again to make sure that the GOP were elected and their Presidential nominee would keep control over the Senate and the House of Representatives.

They used the same technique, spear-phishing, and left fingerprints that leading cybersecurity experts have tied to Russian intelligence.

According to CNN, the emails in question appeared to have been sent from a State Department official and contained a PDF attachment that, if opened, would allow the hacker access to the recipient’s computer.

“It is probable that Russian intelligence again attempted to infiltrate DNC computers in November 2018 unlawfully.”

The timing and content of these emails were consistent with the practices of the Russian hacking group known as Cozy Bear, one of the two groups that hacked the DNC before the 2016 U.S. presidential election.

According to the cybersecurity firm FireEye, Cozy Bear attempted to hack over 20 entities in November 2018, including clients in local government, transportation, defense, law enforcement, and military.
