SPANCHAT HAS ADVISED its users to be wary when using third-party apps, and has asked Apple and Google to remove any in the iTunes and Google Play stores.
Snapchat's warning comes after 'over 100,000' images were leaked on 4chan, which third-party app Snapsaved later took the blame for.
Following SnapSaved's admission, Snapchat said in a blog post: "A third-party application is any application that accesses the Snapchat API, but hasn’t been built and maintained by our company.
"Unfortunately, these applications often ask for Snapchat login credentials and use them to send or receive snaps and access account information.
"It takes time and a lot of resources to build an open and trustworthy third-party application ecosystem. That's why we haven’t provided a public API to developers and why we prohibit access to the private API we use to provide our service.
"We'll continue to do our part by improving Snapchat's security and calling on Apple and Google to take down third-party applications that access our API."
SnapSaved took responsibility for the high-profile Snapchat leak earlier this week. It said in a statement "In response to recent media events and the statement made by Pastebin, I would like to inform the public that snapsaved.com was hacked, the dictionary index the poster is referring to was never publicly available. We had a misconfiguration in our Apache server.
"SnapChat has not been hacked, and these images do not originate from their database.
"As far as we can tell, the breach has affected 500MB of images, and 0 personal information from the database.
"The recent rumours about the snappening are a hoax. The hacker does not have sufficient information to live up to his claims of creating a searchable database."
While it appears that the hackers' claims might not be exactly true, they boasted on 4chan last week that they have obtained 13GB of images via a third-party Snapchat application, equating to "at least 100,000 pictures" that their owners will have assumed had been deleted.
According to a report at Business Insider, users of 4chan had already begun downloading the files last week, and were creating a searchable database that will allow people to locate the stolen images by Snapchat username.
This has rung alarm bells at 4chan, which noted that the collection of photos includes a large amount of child pornography. Half of Snapchat's user base is aged between 13 and 17.
The report notes that the database was hosted on viralpop.com, a fake website that infected computers with malware, which has since been suspended and taken offline - but not before "thousands" of people managed to get their hands on the leaked Snapchat images.
In a statement, Snapchat said that its servers "were never breached and were not the source of these leaks".
"We vigilantly monitor the App Store and Google Play for illegal third-party apps and have succeeded in getting many of these removed."
Mark James, security specialist at ESET said this latest hack once again raises the importance of keeping your data secure.
He said: "You are responsible for making sure that you keep your password secure and safe” and allowing a third party website or application access to your data is not keeping your password secure and safe.
"This incident again showed that it’s all about perception of what is secure and what is not. The best advice I can offer in this case and the next 'when it happens' is do not use your smartphone or tablet to take images of you or your partner if you want them to remain private."
Snapchat hasn't had much luck when it comes to security. Earlier this year, hackers posted the usernames and account details of over four million of the application's users. µ
