Nintendo Switch 2 Jailbreak Achieved with OpenAI Codex
A developer known as 'pepsipu' has released the first jailbreak for the Nintendo Switch 2, leveraging OpenAI's AI coding agent Codex. The developer built a physical AI harness using Jet-KVMs to send controller inputs and analyze HDMI output, and a remote light switch to reboot the console after crashes. The software exploit took two weeks and targeted a vulnerability in the Smile Basic 4 software available on the Switch 2 eShop, allowing code execution on the console. The jailbreak enables game mods, such as adding characters like Peter Griffin and an Angry Bird to Mario Kart World. However, it is a 'tethered' jailbreak, meaning the hack is lost on every reboot. The developer aims to make it permanent, but Nintendo has already removed Smile Basic 4 from its eShop in response, potentially leading to legal action.
This news is about a niche gaming console jailbreak, not directly related to AdTech, MarTech, or advertising. The involvement of OpenAI Codex is tangential to the core event.

Unpatchable Apple A12/A13 Boot ROM Flaw Enables Jailbreak
Paradigm Shift, an offensive cybersecurity company based in Barcelona that sells spyware and hacking tools to government agencies, published technical details and a proof-of-concept for a vulnerability it calls “usbliter8.” The flaw affects the Boot ROM on Apple A12 and A13 chips (used in iPhone XS, XR and iPhone 11), code burned into the chip that cannot be patched. Exploiting the bug requires physical access to the device (a cable connection) and could allow attackers or researchers to defeat boot-level security checks—potentially serving as a building block for iPhone jailbreaks when combined with other vulnerabilities. Paradigm Shift recommends migrating to newer hardware as the primary mitigation. The publication underscores that while modern iPhones are difficult to compromise, immutable low-level firmware bugs remain a persistent risk.
First Untethered Jailbreak Since iOS 9 Demonstrated on iOS 27
Security researchers have demonstrated the first untethered jailbreak for Apple's mobile operating system since iOS 9 (2019) at the Hexacon security conference in Paris. The jailbreak reportedly works on iOS 27.0.1 and the new iPhone 18 Pro family. An untethered jailbreak survives reboots without requiring a connection to a computer. The team behind the exploit, Calif.io, used AI to discover the exploit chain, although the specific AI models were not disclosed. Observers speculate the exploit was developed by analyzing Apple's security fixes in the iOS 27.2 beta compared to iOS 27.0.1. Notably, no active exploitation of these vulnerabilities has been observed so far. Apple has not commented on the jailbreak, but it is expected to close the security gaps in an upcoming update. The researchers previously demonstrated using AI for kernel exploits on macOS.
Trump Asks Anthropic to Block All Jailbreaks
Gary Marcus published a Substack post (June 17, 2026) responding to WIRED reporting that White House officials told Anthropic it must ensure its Fable 5 model cannot be jailbreaked if it is to be rereleased. Security experts quoted by WIRED say completely preventing jailbreaks may be impossible. Marcus argues the incident highlights a broader problem: current next‑token LLM architectures and existing guardrails are inherently inadequate for fully preventing circumvention. He frames the issue as a generative-AI problem rather than solely an Anthropic problem and states that society will either need to curb LLM deployments or accept the associated risks.
