Is your Facebook Inbox secure? It may seem more secure than your news feed (wall) but as always on the internet nothing is secure, isolated and nothing offers privacy.
Security researcher Inti De Ceukelaire described this week in detail at Medium blog how he was able to see private connections shared between users of the largest social network using Facebook's detection tool. The crawler is used to obtain details from a address URL to display them the way you see links on Facebook: with title, description, and an image thumbnail.
Through his experiments, De Ceukelaire was able to discover a number of objects that Facebook assigns to a link each time it was shared by a user, and thus figured out the exact URL it represents. These URLs can include anything. From videos, news, photos, private Google Docs, and more.
When the researcher contacted Facebook about the matter, the company he replied that this is normal as this is how the crawler works, and that this is exactly what the process is intended for.
De Ceukelaire is a developer and was able to take advantage of the tool without Facebook being able to locate and stop him.
This gives us another interesting insight into exactly how it addresses the URLs you share Facebook. On the one hand, the social network with the same function often stops unwanted and malicious addresses in the news feed.
But knowing all the above, who can trust the social network and share with their friends sensitively privacy; Needless to say, every link that "drops" into the social network is scanned and analyzed, regardless of whether you post on your "wall" or on a proprietary conversation of Messenger.
If you do not want the links to your personal photos or any other data you share in Facebook, be checked by strange developers, the publication of De Ceukelaire came to hit you the bell.
