When an individual acquires a zero-day and turns it into a product to be bought by people to freely target users of the vulnerable software, they are treated like a crook. When Cellebrite do it, it should be no different. Here is the statement from Cellebrite on the matter: β€œWe do not disclose or publicize the specific capabilities of our technology. This practice is central to our security strategy, as revealing such details could provide potential criminals or malicious actors with an unintended advantage.” A software developer is entitled to know that their software is being / attempted to be exploited by a wealthy, influential actor. This is called responsible disclosure, a virtue of the security community these companies don't follow. What we do against these groups is an act of self-defence of our product and work. GrapheneOS, Google, Samsung, Apple and the greater mobile security community is neither a "potential criminal" or a "malicious actor". These authoritarian talking points are stale and come from the same playbook as "Think of the children" and other fallacy phrases meant to attack you as being a danger for something as simple as wanting to protect yourself. Vulnerabilities don't just exist for the bad guys. All vulnerabilities are to be patched when uncovered. At the bare minimum, a single so-called illicit use of it anywhere in the world immediately makes their exploit a cyberweapon that must be neutralised. Them being an exploit alone is the only justification we need to seek disrupting these threat actors' work. View quoted note β†’
Both patches in the November 2025 Android Security Bulletin have been included since our September 2nd release. It's now known that our 2025090200 and later releases provided the 2025-11-05 Android security patch level early due to shipping extra patches. It's because these two patches were included in the full September 2025 bulletin patches we shipped but were made optional until November 2025. Later in September, we started our security preview releases able to provide Android Security Bulletin patches around 2-3 months early. Our security preview releases currently have the December 2025 and January 2026 patches. December 2025 has a huge set of patches due to being a quarterly patch level. January 2026 will likely be empty. We should have quarterly March 2026 patches to ship within a couple weeks. Due to having early access to the patches which we can use for our security preview releases, we've been able to determine that a subset were pushed to AOSP and other projects prior to the official embargo ending which means we'll be including those in our regular releases soon. Our security preview releases shipped all available December 2025 security patches in September 2025 and have continued adding the remaining patches. It should be frozen soon, but most of the patches have remained the same since September. Some were deferred to future bulletins. The new security patch system being used by Android is confusing for users and bad for the security of anyone not using #GrapheneOS with our security preview releases. We could have set the patch level string to 2025-11-01 in early September but in this case we didn't do that.
GrapheneOS has diminished exploit capabilities for Cellebrite a third time. They are no longer able to Full Filesystem extraction an unlocked device. This prevents extraction of hidden operating system and application data. Given it is unlocked, they're still accessing all the important stuff though. This could be an indicator of their target. They are likely to move their resources to attempt researching an exploit targeting the Titan M2 secure element or for extraction for AFU Locked devices rather than be concerned about extracting a device already unlocked. We routinely receive this information from sources familiar with Cellebrite. However, do you have more information on exploit vendors? Do the right thing. Tip off #GrapheneOS at security@ our domain or contact the project account on our platforms. We will respect your privacy. We have made upstream security reports to Google and Apple.

A user on our community platforms submitted a grainy photo from a Cellebrite Premium sales pitch suggesting that they lost support for full filesystem extractions on *UNLOCKED* #GrapheneOS devices. This would mean that Cellebrite can no longer extract hidden operating system data or application data not available to the user when they know the users password. They are still unable to bypass the Titan M2 secure element backed brute force protections. image
As GmsCompat (sandboxed Google Play compatibility later) development continues we get more compatibility with certain apps due to adding more workarounds with certain apps not working, like our recent fix with a shim for font loading. In the late future we could look at how to reduce the need to install any Google Play services implementations for apps, make them just work without any services, sandboxed or otherwise. Google Camera, Android Auto, and some others just work on GrapheneOS.
