Snapchat photo leak: Who's behind it?

Oh, no, not again. More photos have been leaked online, but this time they're not of celebrities; they could be from any of Snapchat's 100 million monthly active users. Welcome to your nightmare, and just in time for Halloween, too!

At least 200,000 Snapchat accounts have reportedly been hacked into and leaked on the image board 4chan. If the name of that site sounds familiar, it's because that's also where the nude photos of celebrities were leaked at the end of August.

Blogger Kenny Withers, who is credited with first reporting the hack, said that a 4chan user claimed to have hacked the accounts with the third-party app Snap Save.

"My app do[es]n't save users' snaps on our server; Snap Save just save[s] snapchats on user's phone," Snap Save's owner said.

However, the legitimacy of the leak has come into question. Some believe the photos were already available online through websites and Reddit threads dedicated to sharing saved Snaps. A reverse image search performed by independent privacy and security researcher Ashkan Soltani backs up this claim.

Soltani also tweeted that the person claiming to be the leaker says he won't leak the photos because of privacy concerns, although Soltani also points out that there is now a website hosting possible "Snappening" videos, some of which are NSFW.

The hackers reportedly hoped to create a giant database that could be searched by username and that included the 13 GB of photos and videos from the hack. Business Insider reports it is already being worked on.
