A newly published writeup lays out a way to hijack the video stream the PlayStation 5 sends out over RTMP when broadcasting gameplay to services like Twitch.
Developer Yash Garg posted a technical breakdown on his blog explaining how the PS5's RTMP stream - the protocol used to broadcast gameplay to platforms like Twitch and YouTube - can reportedly be hijacked. The post picked up traction on Hacker News, sitting at 33 points and two comments as of Monday. The exact method, required access, and which PS5 firmware versions are affected are laid out in Garg's original post rather than summarized elsewhere. Sony has not issued any public response.
RTMP hijacking isn't new - it's a known weak spot in unencrypted streaming setups generally, since the protocol wasn't built with strong authentication in mind. What's notable here is that it's being demonstrated against a mainstream console feature that millions of PS5 owners use casually to stream to friends or followers, not specialized broadcast software. If the technique holds up, it's a reminder that convenience features bolted onto closed hardware often inherit the security assumptions of the older tech they're built on.
For now, treat it as one researcher's writeup generating some Hacker News chatter - not a confirmed, widespread vulnerability with a patch timeline attached.
