A third ransomware negotiator has been jailed for helping a notorious ransomware group extort American victim companies into paying the hackers.

Market research company Klue told customers that it believes the hacking group that stole their data is now deleting it. The company, however, warned about a second group of hackers wanting ransom.

Huntress, HackerOne, Jamf, Recorded Future, and Tanium are among the cybersecurity companies that had data stolen following an earlier breach at market research firm Klue.

The open source project said hackers stole its codebase and threatened to publish its source code if the company did not pay.

The cybercrime group ShinyHunters claimed to have hacked Instructure again, defacing the login pages of several Instructure customer schools with an extortion message.
