Suspected Russian cyberattack waged on Clinton campaign just days before vote

In the closing days of the 2016 election campaign, hackers believed to be working for Russian intelligence launched a new wave of attacks on Hillary Clinton’s campaign and the Democratic National Committee — a previously unreported cyberoffensive that heightened concerns, now endorsed by the CIA, that the Russian government was seeking to influence the outcome of the election in favor of Donald Trump, according to sources familiar with the investigations into the attempted intrusions. The attacks came in the form of so-called “phishing” emails sent to nearly a dozen campaign and committee staffers in a renewed effort at penetrating their networks, said Dmitri Alperovitch, the co-founder and chief technology officer of CrowdStrike, the cybersecurity firm hired by the DNC to repel attacks on its network.
