# PS4 4.05 Kernel Exploit --- ## Summary In this project you will find a full implementation of the "namedobj" kernel exploit for the PlayStation 4 on 4.05. It will allow you to run arbitrary code as kernel, to allow jailbreaking and kernel-level modifications to the system. This release however, *does not* contain any code related to defeating anti-piracy mechanisms or running homebrew. This exploit does include a loader that listens for payloads on port `9020` and will execute them upon receival. You can find fail0verflow's original write-up on the bug [here](https://fail0verflow.com/blog/2017/ps4-namedobj-exploit/), you can find my technical write-up which dives more into implementation specifics ~~here~~ (this is still in progress and will be published within the next few days). ## Patches Included The following patches are made by default in the kernel ROP chain: 1) Disable kernel write protection 2) Allow RWX (read-write-execute) memory mapping 3) Dynamic Resolving (`sys_dynlib_dlsym`) allowed from any process 4) Custom system call #11 (`kexec()`) to execute arbitrary code in kernel mode 5) Allow unprivileged users to call `setuid(0)` successfully. Works as a status check, doubles as a privilege escalation. ## Notes - This exploit is actually incredibly stable at around 95% in my tests. WebKit very rarely crashes and the same is true with kernel. - I've built in a patch so the kernel exploit will only run once on the system. You can still make additional patches via payloads. - A custom syscall is added (#11) to execute any RWX memory in kernel mode, this can be used to execute payloads that want to do fun things like jailbreaking and patching the kernel. - An SDK is not provided in this release, however a barebones one to get started with may be released at a later date. - I've released a sample payload [here](http://www.mediafire.com/file/n4boybw0e06h892/debug_settings.bin) that will make the necessary patches to access the debug menu of the system via settings, jailbreaks, and escapes the sandbox. ## Contributors I was not alone in this exploit's development, and would like to thank those who helped me along the way below. - [qwertyoruiopz](https://twitter.com/qwertyoruiopz) - [Flatz](https://twitter.com/flat_z) - [CTurt](https://twitter.com/CTurtE) - Anonymous E-DB Note: Download ~ https://github.com/offensive-security/exploit-database-bin-sploits/raw/master/bin-sploits/43397.zip Source: exploit-db.com

Millions of PSN gamers, who were hit by a massive data breach on Sony's Playstation network back in 2011, are finally being offered the opportunity to claim compensation from the company. Stateside victims of the hack attack – PSN, Qriocity and Sony Online Entertainment subscribers who held an account before 15 May 2011 – have been encouraged to file an online form as part of a settlement deal to end a class action lawsuit brought against the Japanese tech giant.A number of claims can be submitted by U.S. netizens affected by the assault on Sony's computer network systems. Victims can either claim one free game, up to three themes or a free subscription to Playstation Plus for three months for those subscribers not already signed up to that option. While those affected by identity theft can claim up to $2,500 in compensation. Sony, which offered a $15m settlement deal to PSN gamers in July last year, said: The proposed settlement offers payments equal to credit balances (if applicable credit balance is $2 or more) in inactive accounts, game and online service benefits for holders of active accounts, and reimbursements for certain out-of-pocket expenses from any identity theft proven to have resulted from the intrusions. In the UK, Sony was slapped with a £250,000 fine by the Information Commissioner's Office, after it concluded that the Data Protection Act had been violated following the 2011 hack attack. The personal info of millions of Brits – including names, addresses and account passwords – were stolen by malefactors who infiltrated Sony's PlayStation Network systems. In January 2013, Blighty's data cops concluded that the breach of around 77 million gamers could have been prevented if Sony had adequate security measures in place, such as hashing and salting log-ins and keeping system patches up to date. Despite that admonishment, Sony has refused to accept any responsibility for the attack. ® Source
