Developer aomsin2526 releases the second build of BadHTAB , the PlayStation 3 hypervisor exploit rooted in a vulnerability discovered by legendary hacker XORLOSER and later exploited by GeoHot in 2010.

The name comes from a bug in the management of the Hash Table (HTAB), a fundamental data structure of the hypervisor that maps virtual memory to physical memory, ensuring access control.

The exploit uses a combined hardware-software technique: a hardware glitch briefly interrupts a RAM signal to ground, while a software payload uses this interruption to suspend the HTAB data pointer while invalidating an entry.

This bug allows an otherwise protected region of memory to remain valid by providing full read and write permissions to a small area.

This area can then be manipulated by the hypervisor itself, allowing full access to the console’s memory.

BadHTAB differs from the original GeoHot version in that it applies to every PS3 model with PS3HEN , including those not compatible with Custom Firmware.

For the first time, it offers full access to the hypervisor on consoles without Custom Firmware, unlocking some features typical of custom firmware.

The first public demonstration of BadHTAB took place on March 30, when Zecoxao shared on Twitter/X an image of Red Ribbon (a Linux distribution for the PS3) running on a Super Slim with firmware 4.84.

This marked a significant milestone, considering that the Super Slim and some Slim models (3000 series) do not support permanent custom firmware or downgrades to vulnerable versions like 3.55, due to enhanced security measures after firmware 3.56.

The second build , represents an evolution of the project. Although no detailed release notes have been published, the five commits in the repository and the updated precompiled files suggest improvements in stability, compatibility, or glitch processing .

Compared to the initial release, this build may have optimized glitch automation – essential on GameOS, where the vulnerability window is much narrower than on Linux – or fixed bugs reported by the community.

The public source code invites further contributions, making BadHTAB a collaborative project in full development.

Main Components

BadHTAB is based on two key elements:

BadHTAB (Software) : The software component, distributed as a PKG file for PS3, handles the exploit once the glitch is initiated . It is responsible for accessing the hypervisor and executing user-configured functions.
ps3pulldown2 (Hardware) : The hardware part, based on a Raspberry Pi Pico (RP2040), communicates with the PS3 via USB port and automates the glitch . Unlike the Linux version, which tolerated a wider glitch window , on GameOS automation is essential to ensure minimal stability.

Despite these advances, the success rate remains low (5-10%), making BadHTAB an option for experienced users and patients, not for everyday use.

It also requires soldering onto the motherboard, which is not a complex process but can destabilize the console’s boot if not done correctly.

Unlocked Features

Once the exploit is successfully executed, BadHTAB offers a range of possibilities:

Hvcall 114 without restrictions : Allows you to map any memory area, bypassing standard limitations.
New hvcalls (peek/poke/exec) : Introduces hypervisor calls to read (hvcall 34), write (hvcall 35), and execute code (hvcall 36) in the LV1, providing fine-grained control.
LV1 Memory Dump : Allows you to save hypervisor memory to a file for analysis or preservation.
Booting a custom lv2_kernel.fself : Allows loading a LV2 kernel in fself format , opening the door to advanced modifications.
OtherOS Support : Re-enables the ability to boot petitboot and Linux, such as Red Ribbon , on modern consoles.

Note: Using the boot functions ( lv2_kernel or OtherOS ) removes the new hvcalls, but hvcall 114 remains active, allowing you to reinstall them manually .

Potential for a Custom Firmware

The most intriguing question is whether BadHTAB could lead to a permanent Custom Firmware, especially for the Super Slim and Slim 3000.

A Custom Firmware would offer direct booting of backups, installation of PKGs without repeated exploits, and superior stability to HEN. However, there are significant obstacles:

Permanent access to flash memory : BadHTAB temporarily accesses the hypervisor, but does not modify the NAND/NOR. A Custom Firmware requires a stable patch of the firmware or boot process, bypassing secure boot and signature checks.
Hardware Protections : After firmware 3.56, Sony introduced stronger signing keys and anti-downgrade checks in Syscons . BadHTAB does not appear to be able to tamper with these.
Glitch Stability : The dependence on a hardware intervention introduces instability, incompatible with the reliability of a Custom Firmware.

Compared to historical Custom Firmware (e.g. on firmware 3.55), BadHTAB clashes with a hardened boot chain.

It could evolve into an advanced HEN with extended kernel access, but a Custom Firmware would require a vulnerability in Syscon or a way to permanently patch the official firmware. Without these discoveries, it remains a temporary exploit.

BadHTAB Installation Guide

Here is a detailed guide to install and use the second build of BadHTAB :

Hardware Requirements

Raspberry Pi Pico (RP2040).
0.1mm magnetic wire.
Welding Tools
PS3 Super Slim (this guide is specific to this model).

Hardware Installation

Identifying the solder points : Locate the RQ resistors on the motherboard (e.g. RQ8 on the left side, RQ7 on the right). Consult the service manual or desolder the RAM to trace them manually.
Welding :
- Solder one wire to RQ8 (left side) and the other end to GP15 of the Pico.
- Solder a second wire to RQ7 (right side) and the other end to GP16 of the Pico.
Assembly : Reassemble the console, making sure the wires do not touch the ground or metal (keep them suspended).
Installing the Pico firmware : Hold down the BOOTSEL button while connecting the Pico to the PC, copy the file.uf2(from the repository) to the drive that appears and disconnect.
Boot Test : Connect the HDD to the PS3 and turn it on with the cover off to test booting (the HDD light should be flashing). If it doesn’t boot, adjust the wires. Use a screwdriver to short out the power button (fragile on Super Slims).

Software Installation

Installing the PKG : Download the fileBadHTAB.pkgand install it on your PS3 via USB or Package Installer .
Configuration :
- Dump LV1 : Create an empty file ( BadHTAB_doDumpLv1.txtfor 16 MB or BadHTAB_doDumpLv1_240M.txtfor 240 MB) in /dev_hdd0/.
- Start lv2_kernel.fself : Decrypt the file lv2_kernel.selfin .elf, convert it to .fselfwith make_fself.exe(Sony SDK), create a file BadHTAB_doLoadLv2Kernel_Fself.txtin /dev_hdd0/and copy the file lv2_kernel.fselfto /dev_flash/sys/(use /dev_blind/with webMAN MOD).
- Boot OtherOS : Create the file BadHTAB_doOtherOS.txtin and copy the dtbImage.ps3.fself/dev_hdd0/ file to (free up space by deleting ps1emu/ps2emu/pspemu if necessary)./dev_flash/sys/
Safe Shutdown : Turn off the console before proceeding.

Executing the Exploit

Connect the Pico to the USB port on the PS3.
Launch BadHTAB from the XMB menu.
Listen to the beeps:
- A short triple beep indicates the exploit has started.
- During the glitch , the Pico LED will flash and you will hear frequent beeps. If they stop or the console shuts down, the attempt has failed: restart and try again (this may take hours).
- Two short triple beeps with a pause indicate success: The exploit patches LV1, installs hvcalls and executes the chosen configurations.
- With lv2/OtherOS , booting happens now; otherwise, a 5-second beep signals a return to the XMB.
Logs are saved in /dev_hdd0/BadHTAB.txt.

Perspectives and limits

BadHTAB ‘s second build cements its place as an innovative tool, bringing CFW-like functionality to permanently unmodified consoles.

Support for firmware 4.70 and later and openness to Linux make it a valuable option. However, the low success rate (5-10%), complexity of soldering, and non-persistent nature limit it to a technical audience.
