The attack leverages CTP (Creative Transport Protocol), a proprietary command interface that allows firmware replacement with no code signing or verification. This means an attacker within Bluetooth range can reflash the speaker's firmware and potentially use it as a proxy to infect the connected PC. Creative Technologies does not consider this behavior a vulnerability. ## Full article daily.dev links to this article rather than hosting it.
