A thorough examination of the sampled records by Privacy Sharks’ security analysts found that LinkedIn profile details (full names, phone numbers, addresses, personal information, and gender) were included in the post.

Scraping is believed to have been used to collect 500 million LinkedIn records on sale in April. This method is among the most common means deployed by hackers to retrieve public information on the internet. This information can also be used to perform malicious activities such as sending phishing emails. Hackers can then use this information to make a profit by selling it online.
