LinkedIn scraping of 700M data was ‘for fun’ says hacker

Past month we described a LinkedIn scraping that uncovered the info of 700 million people – some 92% of all these on the company. The knowledge included spot, mobile phone numbers, and inferred salaries.

The person driving it has now been identified, and says that he did it “for fun” – nevertheless he is also promoting the information …

Track record

Details scraping is a controversial topic. At its easiest, it indicates crafting a piece of program to pay a visit to a webpage, read through the information shown, and then incorporate it to a databases.

Extra usually, men and women will use APIs (application programming interfaces) provided by the internet service for legitimate purposes, and use it to get substantial quantities of details.

It is controversial because, on the 1 hand, all those undertaking the scraping can argue that they are only accessing publicly accessible facts – they are simply accomplishing so in an productive way. Other folks argue that they are abusing instruments not meant for the reason, and that there is far more details out there through APIs than is noticeable on web-sites, earning it tricky for customers to know what information has been uncovered.

There is even controversy over terminology. Numerous stability specialists argue that it isn’t a security breach if the facts is offered for general public access. I would argue that if a provider like LinkedIn doesn’t spot a person scraping practically hundreds of tens of millions of data, that is a significant stability failing.

LinkedIn scraping for enjoyable – and profit

BBC News spoke with the guy who took the details, underneath the title Tom Liner.

How would you feel if all your details was catalogued by a hacker and place into a monster spreadsheet with millions of entries, to be bought on the internet to the highest paying out cyber-legal?

That is what a hacker contacting himself Tom Liner did last thirty day period “for fun” when he compiled a databases of 700 million LinkedIn people from all above the earth, which he is offering for all over $5,000 (£3,600 €4,200) […]

In the situation of Mr Liner, his most up-to-date exploit was announced at 08:57 BST in a put up on a notorious hacking forum […] “Hi, I have 700 million 2021 LinkedIn records”, he wrote. Incorporated in the publish was a connection to a sample of a million documents and an invite for other hackers to make contact with him privately and make him delivers for his database.

Liner claims he was also at the rear of the scraping of 533M Facebook profiles back in April (you can examine regardless of whether your info was grabbed).

Tom instructed me he made the 700 million LinkedIn databases working with “almost the precise identical technique” that he made use of to produce the Facebook list.

He said: “It took me various months to do. It was quite intricate. I experienced to hack the API of LinkedIn. If you do as well a lot of requests for person data in a person time then the system will permanently ban you.”

LinkedIn denies that Liner utilized its API, but cybersecurity firm SIS Intelligence suggests we have to have a lot more controls over their use.

CEO Amir Hadžipašić claims the facts in this, and other mass-scraping occasions, are not what most folks would expect to be offered in the general public domain. He thinks API programmes, which give more info about users than the general community can see, really should be more tightly controlled.

“Large-scale leaks like this are about, offered the intricate depth, in some conditions, of this information and facts – this sort of as geographic places or non-public mobile and email addresses. 

“To most men and women it will arrive as a surprise that there’s so a lot data held by these API enrichment providers.

Safety pro and haveibeenpwned.com proprietor Troy Hunt claims he does not consider API misuse to be a security breach, but generally agrees on the need for far more control.

“I do not disagree with the stance of Fb and others but I come to feel that the response of ‘this isn’t a problem’ is, while potentially technically correct, missing the sentiment of how useful this consumer data is and their probably downplaying their individual roles in the creation of these databases.”
