The Instagram Scam That Tricked 100,000 Users Into Giving Away Passwords | Apps and Widgets for any use, mostly for education and FREE |
An app called InstLike promised free likes and followers on Instagram, but asked users to provide their usernames and passwords, turning them into a botnet.


Moreover, a user would get 20 free Likes if he used the hashtag #instlike_com in his own photo captions. A search on Instagram reveals that more than 500,000 photos already contain that hashtag.


All these features made InstLike a sophisticated ecosystem that employed thousands of voluntary "zombie" accounts — but it depended on their naiveté and willingness to give up their passwords.


For Narang, who is experienced in the realm of social media-based scams, the sheer volume of people involved is scary.
