Terrorists are allegedly exploiting a decade-old vulnerability in Twitter's systems to hijack dormant accounts and spread propaganda online. According to TechCrunch, there has been a resurgence in the number of accounts being hacked in recent weeks, many of which had been inactive for years. The hackers are reportedly using the fact that, prior to this summer, those opening an account with Twitter did not need to confirm their email addresses, meaning there are a number of accounts on the platform not linked to real email addresses or expired addresses. This allows hackers to then create the email address, and so gain access to the attached account. Security experts said this issue was "all too well known", but that it was hard for Twitter to manage the problem. "Twitter could expire accounts after a certain period of dormancy, but legacy accounts that were created without real associated emails will be vulnerable to this sort of hijack," said Robert Pritchard,
