A free app called InstLike has lured 100,000 Instagram users into sharing their usernames and passwords by promising them free followers and Likes, according to a report by Symantec shared exclusively with mashable.com.

“The app asked them their usernames and passwords after downloading, turning them into willing participants of a giant social botnet”, Mashable said.

Despite the apps claims that it does not steal the users’ account, it actually did that. Once the gullible users signed up for the free app, InstLike would begin Liking random photos and following random users.
