So, what I would like to show right here is a lively vulnerability inside Facebook, which lets in malicious customers to query, um, e mail addresses inside Facebook and have Facebook return, any matching users.

Um, this works with the front stop vulnerability with Facebook, which I’ve stated to them, made them conscious of, um, that they do no longer reflect on consideration on to be essential sufficient to be patched, uh, which I would think about to be pretty a significant, uh, privateness violation and a large problem.

This technique is presently being used via software, which is accessible proper now inside the hacking community.

Currently it is being used to compromise Facebook money owed for the cause of taking over pages agencies and, uh, Facebook marketing money owed for the sure financial gain. Um, I’ve set up this visible instance inside no JS.

Um, I have queried or I’m querying 65,000 e-mail addresses. And as you can see from the output log here, I’m getting a tremendous quantity of effects from them.

If I have a seem at the output file, you can see I have a person ID title and the electronic mail tackle matching the enter e-mail addresses, which I have used. Now I have, as I say, I’ve spent perhaps $10 the usage of two to purchase 200-odd Facebook accounts. And inside three minutes, I have managed to do this for 6,000 accounts.

I have examined this at a large scale, and it is feasible to use this to extract feasibly up to 5 million electronic mail addresses per day.

Now there used to be a present vulnerability with Facebook, uh, beforehand this year, which used to be patched. This is in reality the precise equal vulnerability. And for some reason, in spite of me demonstrating this to Facebook and making them conscious of it, um, they have instructed me immediately that they will now not be taking motion towards it.

So, I am attaining out to human beings such as yourselves, uh, in hope that you can use your affect or contacts to get this stopped, due to the fact I am very, very confident.
