Hackers are spreading Islamic State propaganda by hijacking dormant Twitter accounts

Hackers are using a decade-old flaw to target and hijack dormant Twitter accounts to spread terrorist propaganda, TechCrunch has learned. Many of the affected Twitter accounts appeared to be hijacked in recent days or weeks — some longer — after years of inactivity. A sudden shift in tone or the language used in tweets often gives away the hijack — usually a single tweet in Arabic, sometimes praising Allah or retweeting propaganda from another account.
