A hacker group sells data from 10 companies, including the online dating app Zoosk, the US newspaper Star Tribune and the Food Delivery Service Chef, which has over 73 million user records on the Dark Web for $ 18,000 ( almost 13.6 lakh).

Other companies print chatbooks, the South Korean fashion platform SocialShare, the online marketplace Minted, the online newspaper Chronicle of Higher Education, the South Korean furniture magazine GGuMim, the health magazine Mindful and the Indonesian online shop Bhinneka, reports ZDNet.

The databases listed have 73.2 million user records, with each database sold separately.

The hacker group is known as ShinyHunters, the same group behind the breach of private repositories on Microsoft’s GitHub (the hacker probably bought around 1,200 private repositories) and Tokopedia, Indonesia’s largest online store, which contains a database of over 90 Millions of user records have been sold.

A Microsoft spokesman was quoted as saying that the company is investigating the incident. The same hacker group also sold a database of 22 million user records from the online learning platform Unacademy on the Dark Web.

Bengaluru-based edtech company Unacademy said that all of its users’ sensitive data is secure and the company is addressing the security issue.

“We want to assure our users that no sensitive information such as financial information or location has been breached,” said Hemesh Singh, co-founder and CTO of the Unacademy.

Encouraged by the profits from the Tokopedia sale, the same group has now listed the databases of 10 other companies.

“Some believe that the ShinyHunters group has ties to Gnosticplayers, a hacker group that was active last year and has sold more than a billion user credentials in dark web marketplaces because it operates in an almost identical pattern,” said it in the report..
