TechCrunch reports:

A hacking group has taken credit for a breach at market intelligence provider Klue that allowed hackers to steal reams of data from the company’s corporate customers, which include some of the biggest names in cybersecurity.

Vancouver-based Klue, which lets companies conduct market research by connecting their data to its systems, said on Friday that hackers had stolen data from an unspecified number of its customers during a cyberattack a week earlier.

Cybercrime group Icarus took credit for the breach, saying on its leak site that it will publish the stolen data on Monday if the company does not pay the hackers’ ransom.

Klue has not said how many of its hundreds of customers are affected.
