A Sony-backed exploit that allowed attackers to launch attacks on Microsoft’s Xbox Live service is now being used by hackers to target Sony-owned networks, according to security researchers.
The PS4 exploit, known as PS4Locker, was first discovered by researchers at the Symantec security firm, and it was reported to Microsoft on Friday.
Symantec said in a blog post on Friday that it has found PS4 Locker on several PS4 servers.
Microsoft said it has not seen the exploit, which it said could be used to launch network-based attacks on the PS4.
Microsoft said the PSVita system in question is being used to test vulnerabilities in the PlayStation Network, which allows users to download new games and other content for use on the console.
It said the attack appears to be targeted at the PlayStation Vita’s remote login and authentication mechanisms.
The exploit has already been used to target PlayStation consoles, but the attack is also targeting the PlayStation VR headset, which uses Bluetooth to communicate with the PlayStation system and is a common part of virtual reality headsets.
The Sony-sponsored PSV-Link program lets owners use the PlayStation network to connect to other PlayStation consoles using a Bluetooth headset.
That allows users who do not have an existing PlayStation account to log in to a PSV and access content.
Symantsec said the exploit could be exploited in ways that would allow attackers to compromise servers connected to a network, launch attacks and then delete data that could be linked to a user.
The company did not say when the exploit was first released.
Symansec said there are more than 700 vulnerabilities in PS4s hardware, and many are likely to be exploitable if the exploit is widely used.
The PS4 is among the most popular video game consoles in the world, with more than 300 million devices sold worldwide.
