Kinda curious how you never find those dumps by a normal search on Google, basically you have no way to know if your data is there if you don't know where to look. I don't use Facebook but I always suspected my data is there due to friends having me in their contacts and using their apps.

Facebook: "This dataset is old and appears to have information obtained before we made changes last year to remove people’s ability to find others using their phone numbers." Not that "old." Some of those "update" dates are just a few days ago.

Yes but

"But the data appeared to be loaded into the exposed database at the end of last month — though that doesn’t necessarily mean the data is new."

Somewhat curious what the Status key represents in this dump, personally.

You are likely in this database if you added your phone number to your Facebook account. There was a point where if you just typed a phone number into facebook it'd return the person who associated their account with that number.

>ability to find others using their phone numbers."

Ah right, that's why I couldn't find someone...

proper link? I'm curious to see if I'm on there

Check Settings -> Privacy -> Who can look you up using the phone number you provided?

If I understood this story correctly, it was scraped from accounts that had this preference set to public.

> changes last year to remove people’s ability to find others using their phone numbers.

What? That's not true, I reported the issue about user enumeration via phone numbers being possible in Whatsapp, Messenger and Instagram to them last week and they claimed (paraphrased) "it's a feature, not a security issue".

How many people change their phone numbers more than once a decade? How many people change their facebook accounts ever?

The age of this data may be "old" by whatever definition Facebook is using, but it is still of great interest to identity thieves and ne'er-do-wells.
