'Fancy Bear' Targets Democratic Sen. Claire McCaskill'Fancy Bear' Targets Democratic Sen. Claire McCaskill

Fancy Bear, a cyber espionage group believed to operate out of the Russian military agency GRU, has reportedly targeted Senator Claire McCaskill and her staff as they prepare for her 2018 reelection campaign.

This makes McCaskill, a Missouri Democrat, the first named target of Russia's 2018 election meddling, according to a report by The Daily Beast. Many consider her vulnerable given her past criticism of Russia; she has repeatedly accused the Kremlin of "cyber warfare against our democracy" and referred to Russian President Vladimir Putin as a "thug" and a "bully."

Attackers hit McCaskill's campaign with a variant of the password-stealing tactic Fancy Bear used against John Podesta in 2016, the report said. Senate staffers received fake notification emails instructing them to change their Microsoft Exchange passwords. If they clicked, targets were sent to a page disguised to belong to the US Senate's Active Directory Federation Services login. Each phishing email was tailored to its recipient's email address.

Microsoft first reported three hacking attempts on the midterm elections late last week. Experts earlier this year detected a fake Microsoft domain had been registered as a landing page for attacks against midterm candidates, though they didn't identify them at the time.

McCaskill released a statement that said the cyberattack was unsuccessful.
