'State actors' may have accessed Twitter contacts
Twitter has warned that hackers acting on behalf of governments may have accessed the phone numbers of some users. In a statement published on its blog Twitter said: " It is possible that some of these IP addresses may have ties to state-sponsored actors. In December, TechCrunch reported that security researcher Ibrahim Balic had managed to match 17 million phone numbers to specific Twitter users accounts by exploiting a flaw in the contacts feature in Twitter's Android app. The feature is designed to allow people who already have someone's phone number to make contact with them on Twitter. He did not alert Twitter to the vulnerability but included the phone numbers of high-profile Twitter users - such as politicians and officials - in a WhatsApp group in order to warn people affected directly.
