“Hackers are taking over high-profile Instagram users’ accounts and holding them to ransom, it was revealed this week. At least four influencers have lost control of their accounts and received demands to send bitcoin for their return, but in some cases the attackers retained control or deleted the accounts.” In one instance, hackers sent an email offering a sponsorship, taking the account holder to a fake Instagram portal which captured the influencer’s account details. Instagram and security professionals continue to emphasize the importance of using two-factor authentication, which would have prevented most of these attacks.
