LinkedIn data scraping: Records for sale
On April 5th, 2021, through Swascan’s Osint Search Engine tool we identified several sales ads relating to LinkedIn user’s data.
In particular, we identified:
– A post published on April 3rd, 2021 at 00:41AM regarding the sale of “1Billion(1000Million) LinkedIn Records”
– A post published on January 11th 2021 at 05:43 AM regarding the sale of “550million LinkedIn full profiles, emails, phone numbers and recent data”

The author of the ad in question specified what he had available: “I have 520Million +500Million Other Data”. Moreover, he provided evidence and examples to confirm and demonstrate the “reliability” of the data he was selling.
Specifically, for the first 520 million data, he made available a set of data records:
Also, for the other 500million data he provided further details:
Therefore, we decided to investigate the source and the reference date of the data for sale by directly contacting the author of the ad.
Overall, the communication confirmed that the data referred to 2019/2020 and that the entire database of 1billion LinkedIn data was for sale at the price of $1,500.

The seller answers “I will get soon”, proof of an exellent customer service.
Secondly, we identified a post published on April 09th, 2021 with popular LinkedIn data pricing, structured by country.
In this case we are talking about a Database of millions of data records sold for only $ 7.
