Campaigns on their own as cyber threats roil midterms

NEW YORK (AP) — Intelligence officials warn that foreign adversaries continue to wage cyber warfare against the U.S. election systems.

But with the midterm elections just three months away, political campaigns report that they're largely on their own in the increasingly challenging task of protecting sensitive information and countering false or misleading content on social media. The Democratic Party's chief technology officer says there's only so much the party can do despite its best efforts.

Officials in both political parties have intensified cybersecurity efforts, although the known cases of interference have so far overwhelmingly focused on Democrats.

The DNC now has a staff of 40 on its technical team after Russians hacked the party's email system and released a trove of damaging messages in the months before President Donald Trump's 2016 victory.
