A mistake made by website developers left an official re-election website for President Donald Trump open to attack. The error is tied to a website development tool called Laravel, used to test sites before they go live. The tool would allow hackers to hijack the site s email servers and intercept, send or read email messages. The Trump domain that was exposed is DonaldJTrump.com, a website used to solicit campaign donations and invite visitors to sign-up for Trump campaign emails.
