Credential Stuffing Remains the Prime Suspect

Credential stuffing attacks capitalize on stolen user credentials from other platforms in attempts to breach user accounts across different services – a tactic successful when users reuse identical login details.

Roku confirms that less than 400 compromised accounts were used by threat actors to make unauthorized purchases of streaming subscriptions and Roku hardware. The company stresses that attackers could not access sensitive financial information, such as full credit card numbers.
