Ordinary people trust others with their face data far too easily

So much for net-proofing the adults. We are in a modern gilded age, with robber barons collecting our data.

The Lensa app making the viral rounds is owned by Prisma, a firm backed with Russian and Belarusian investment funds.

The above is distinct from another Russian app which hoarded facial data, FaceApp, and went viral (again?) in 2019.

Both apps went viral. Wouldn't be surprised if they were given a social media boost by bots and/or Russia's Internet Research Agency.

Another Russian app, FindFace, was abused to doxx Russian porn stars in 2016.

The decade prior, an Israeli face recognition firm was behind a viral app comparing people's faces to find which celebrity they resembled most. It might have been this one?

And that's all stuff I could readily find links to based on what I remember coming across. I've not yet done an OSINT deep dive.
