New Unpatchable Exploit Targets Apple Devices With A12 and A13 Chips

2 weeks 4 days ago
Researchers have disclosed a new unpatchable BootROM exploit affecting Apple devices with A12, A13, S4, and S5 chips. The attack requires physical USB access and DFU mode, but can let an attacker run code before iOS loads, bypass signature checks, and boot modified software. 9to5Mac reports the details: In a highly detailed technical post published today, the Paradigm Shift Team details usbliter8, a new exploit that "leverages both a hardware bug in the USB controller and a specific configuration flaw present in the device firmware" and cannot be patched. The PS Team explains that ahead of today's disclosure, it shared its findings and worked with Apple Product Security to coordinate the release. The researchers also thanked Apple's security team for its "prompt response, constructive engagement, and cooperation throughout" the process. In a nutshell, this bug affects the following Apple SoCs: A12, S4, S5, and A13. [...] They add that "technical support for A12X/Z is possible," but "it is not currently implemented." That could add the 2018 and 2020 iPad Pro lineups to the list. The way usbliter8 works is: it sends specially crafted data to a device over USB while it is in DFU mode, confusing the USB controller and causing it to write data to the wrong part of memory. That gives an attacker with physical access to the device control over its startup process. From there, they can run their own code before iOS loads, bypass signature checks, and boot modified system software. Importantly, the exploit does not affect or compromise the device's Secure Enclave, which in practice means that data such as passcodes and encrypted user data remain secure. That said, PS Team says that "although usbliter8 doesn't affect SEP itself, it opens up wider attack vectors to compromise the Secure Enclave," adding that "by releasing this exploit publicly, we hope to highlight the real-world impact of these hardware flaws and contribute to a broader understanding of modern SecureROM security." [...] Given that this is also an unpatchable exploit, the researchers note that "affected users should be aware that migrating to newer hardware remains the most effective mitigation."

EU To Soon Classify AWS and Azure As Gatekeepers Under DSA

2 weeks 5 days ago
The European Commission is reportedly preparing to provisionally classify Amazon Web Services and Microsoft Azure as "gatekeepers" under the Digital Markets Act, bringing cloud infrastructure under the law's stricter competition rules for the first time. The designation could require greater interoperability and data portability, making it easier for customers to switch providers, with a final decision expected by the end of 2026. Heise reports: This investigation began in November 2025, when the EU targeted the cloud power of US tech giants. The trigger was outages in cloud services with sometimes significant impacts on other internet services. Shortly before, an approximately 15-hour outage of the AWS cloud in the US meant that not only Amazon's own streaming services but also Atlassian, Docker, Epic Games, and the Signal messenger were unavailable or severely restricted. Shortly thereafter, Microsoft Azure also struggled with an outage, preventing air passengers from checking in and interrupting votes in the Scottish Parliament. As a result, European antitrust authorities have also scrutinized cloud services under the Digital Markets Act for the first time. The major cloud providers, primarily from the US, have so far evaded the EU's Digital Markets Act because a large part of their business is handled through corporate contracts. This makes it difficult to determine the number of individual users. However, this is one of the EU's most important criteria for determining the market power of companies. [...] As gatekeepers, AWS and Azure would be obliged to ensure interoperability and data portability. This would, for example, simplify switching cloud providers and allow customers to link other services with AWS or Azure clouds, instead of being limited to AWS and Azure offerings. Significant fines could also be imposed if the cloud services are found to be in violation of existing regulations.
