Data from 500 million LinkedIn accounts put up for sale

April 10, 2021

The treasure trove of knowledge reportedly contains customers’ LinkedIn IDs, full names, electronic mail addresses, telephone numbers and office info

Mere days after information broke of an information leak that impacted more than half a billion Facebook users, one other large batch of individuals’s private info is being supplied on the market on a hacking discussion board. This time round, the treasure trove of knowledge originates from LinkedIn, though the social networking website says that the data don’t come from an information leak or a breach of its programs.

In response to Cybernews, which broke the story, an unidentified risk actor is purporting to have scraped info from 500 million LinkedIn accounts, which is a minimum of two-thirds of the site’s entire user base. The leaked info, which is up for grabs in an public sale with a minimal four-digit asking value, allegedly contains a variety of knowledge.

To spice up the veracity of their claims, the hacker posted a pattern of some two million data that features customers’ LinkedIn IDs, full names, electronic mail addresses, telephone numbers, gender, office info, and hyperlinks to their social media profiles amongst others. events can view the leaked samples for as little as US$2.

The Microsoft-owned social community, nonetheless, disputes that all the info got here solely from them. “This was not a LinkedIn knowledge breach, and no non-public member account knowledge from LinkedIn was included in what we’ve been in a position to evaluate,” reads the statement by LinkedIn.

“We’ve got investigated an alleged set of LinkedIn knowledge that has been posted on the market and have decided that it’s truly an aggregation of knowledge from plenty of web sites and firms,” mentioned LinkedIn. Nevertheless, the location did go on to verify that the database contains info from publicly viewable member profiles, which can have been scraped from its web site.

It stays unclear whether or not the info that’s being supplied on the market is up-to-date or was collected from a previous data breach suffered by the skilled social community and different corporations.

And, as ESET Chief Safety Evangelist Tony Anscombe astutely noted, most info obtained from knowledge breaches doesn’t actually diminish in worth over time, which suggests sufficiently motivated risk actors might abuse it for all method of assaults. This contains focused phishing campaigns and social engineering assaults or the leaked knowledge might even be used to perpetrate identity fraud.

To mitigate the probabilities of falling sufferer to enterprising cybercriminals, LinkedIn customers would do properly to double down on their safety. Most of all, be cautious of unsolicited messages from strangers that include suspicious hyperlinks or attachments. In case you suspect that your knowledge may be a part of the leak, take into account altering your password, or higher but use a password manager that may generate a hard-to-crack password for you. Enabling multi-factor authentication, ideally utilizing a {hardware} token or a cellular app, can be strongly really useful.
