Instagram scam tricks 100,000 users

More than 100,000 Instagram users fell for a bold, effective scam called InstLike, an app that promised free likes and followers on the photo sharing platform. The app asked users to share their usernames and passwords after downloading, turning them into willing participants of a giant social botnet. After users signed up for the free app, InstLike would begin liking random photos and following random users. It also asked users to buy virtual coins to accrue more likes and followers, according to a new research by security firm Symantec, shared exclusively with Mashable.

“We don’t steal your account,” the app developers promised in the login screen. But InstLike did just that. Symantec estimates that at least 100,000 users fell for the scam. The app was able to add Likes and followers using those real accounts to feed the scam ecosystem. The more people took the bait, the more followers and Likes it delivered.



Despite raising a giant red flag by directly asking for login credentials instead of using the Instagram API, the app was very successful and survived scrutiny from Apple and Google for months, according to Symantec, which spotted the scam in late October. The Android app was created on June 9, while its corresponding iOS app was released on September 19, per app store analytics website App Annie.

After Symantec warned Apple and Google, the app was removed from Google Play and the App Store on October 25 and November 7 respectively. But according to Symantec, it was downloaded and used by many people collectively before then, harvesting a treasure trove of accounts into its botnet. On October 5, InstLike hit its peak in the App Store, where it was No. 22 under most downloaded “utility” apps and No. 571 overall, according to App Annie.

In the Google Play store, InstLike had between 100,000 and 500,000 downloads before it was pulled, with more than 100,000 ratings across app stores, per Symantec. These numbers led the firm to estimate that at least 100,000 users gave their passwords to InstLike, a figure Symantec considers “conservative.” “People didn’t realize that they were being duped into giving their login credentials to this app,” Satnam Narang, the security researcher at Symantec who found out about InstLike, said in an interview with Mashable.

It also convinced people to pay for extra Likes and followers. For almost an entire month, from October 8 until November 7, when it was removed from the App Store, InstLike was either the No. 2 or the No. 1 highest-grossing app among utilities applications, and in the top 200 overall. This is not the first app that has tried to scam social media users by promising Likes and followers, but its tactics were fairly innovative, Narang explained. Normally, this kind of scam apps ask for money upfront, but this app was free and used real accounts, not fake ones.

Users perhaps were naive to give up their passwords, but the app was sophisticated; it used a variety of ways to convince people to pay for virtual coins and spread the app. Instagram sent Mashable the following statement: “Posting automated content to Instagram clearly violates our Terms of Use. We have a team dedicated to stopping abuse on the service and enforcing our policies, including removing content that violates our terms.”
Although the apps have since been removed from Google Play and the App Store, the app’s site,InstLike.com, is still operational. If you downloaded the app and gave out your credentials, Symantec suggests changing your password immediately, then deleting the app from your phone. Otherwise, InstLike will continue to post from your account.
