Breaking, new, by me:

Agents with the Federal Bureau of Investigation (FBI) on Thursday arrested an executive at a Canadian cybersecurity firm in connection with an investigation into the ShinyHunters hacking group that recently relieved the FBI of sensitive data on thousands of agents, multiple sources tell KrebsOnSecurity.

From the story:

"Dubrovsky’s LinkedIn profile states he is the author of Cyber Extortion Strategic Response, a 252-page book that promises to “take readers beyond the ransom note and into the decisions that determine how an organization responds, recovers, and protects what matters.”

edit: Cypfer said Dubrovsky was a managing director until leaving in Nov. 2025, not an ex-founder as his LinkedIn profile says. This link backs that up, saying he was COO and managing partner:
