The incident happened back in June, but the hacker compiling the gigantic list recently made a rather loose statement on the subject.
Last month, news came that someone had compiled a list of 700 million LinkedIn users, including locations and phone numbers.
The case can’t really be considered a traditional hacker attack, as it’s actually a so-called data scratch, so the perpetrator gathered publicly available information into a database, albeit probably using an API that wasn’t exactly invented for that sort of thing.
And using APIs, we have access to far more data than simple browsing, so data scraping can be quite a problem, and the June attack affected more than 90% of the LinkedIn community, so by definition, it’s a pretty serious case. Meanwhile, the BBC also managed to reach out to the hacker behind the leak, who referred to himself as Tom Liner and betrayed that he was compiling the list just for fun.
Most likely, Liner would also like to make a profit, as he allegedly sells the list online for around 5,000 pounds (more than 2 million forints). By the way, if we can believe the hacker, he was certainly behind the data scraping on Facebook in April, when he managed to grab the data of 533 million users. In the attack on LinkedIn, he used almost the same method as on the social site, but it took several months to get the job done because he claimed he had to hack the LinkedIn API.
By the way, the business community site denies that the attacker obtained personal information using the API.
