Google’s Advanced Protection for Vulnerable Users Comes to Android

With nan rise of mercenary spyware and different targeted threats, tech giants for illustration Apple, Google, and Microsoft person spent nan past fewer years trying to fig retired really to protect nan integer lives of their astir at-risk, susceptible users astir nan world. On mobile, nan launch of Apple's iOS Lockdown Mode successful 2022 was 1 concerted effort to shed nonessential functionality successful favour of maximum security—a trade-off astir users wouldn't want to make, but that could beryllium very worthy it for a nationalist figure, activist, journalist, aliases dissident surviving nether regular scrutiny and threat of attack. For years, Google has offered a program for a akin demographic called Advanced Protection that focuses connected adding additional layers of monitoring and information to susceptible users' Google accounts, a halfway portion of galore people's integer lives that could beryllium devastating if compromised. Now, Google is extending Advanced Protection pinch a suite of features for Android 16.

On Tuesday, nan institution announced an Advanced Protection mode for phones moving nan newest type of Android. At its core, nan mode is designed astir imposing beardown information settings connected each apps and services to silo information arsenic overmuch arsenic imaginable and trim interactions pinch unsecured web services and antecedently unknown, untrusted individuals. Advanced Protection connected Android is meant to beryllium arsenic usable and elastic arsenic possible, though, leaning connected Google's quickly expanding on-device AI scanning capabilities to supply monitoring and alerts without having to wholly destruct features. Still, nan mode imposes restrictions that can't beryllium turned off, for illustration blocking phones from connecting to historical 2G information networks and disabling Chrome's Javascript optimizer, which could change aliases break immoderate web functionality connected immoderate sites.

“There are 2 classes of things that we usage to take sides nan user. One is you evidently harden nan system, truthful you effort to fastener things down, you forestall galore forms of attacks," says Dave Kleidermacher, vice president of engineering astatine Android’s information and privateness division. "But 2 is you can't ever forestall each onslaught entirely. But if you tin observe that you've been compromised, you tin return immoderate benignant of corrective action. In user information connected mobile this discovery has ne'er really been a possibility, truthful that's 1 of nan large things we've done here."

This monitoring and discovery capability, known arsenic Intrusion Logging, uses end-to-end encryption to indelibly shop logs from your instrumentality successful nan unreality specified that they can't beryllium accessed by Google aliases immoderate statement speech from you, but besides successful a shape that can't beryllium deleted aliases modified, moreover if your instrumentality and Google relationship are compromised.

Logging and strategy monitoring devices are communal connected laptops and desktops—not to mention successful endeavor IT environments—but offering nan capabilities for consumers connected mobile devices is much unusual. As pinch immoderate strategy that takes information disconnected a instrumentality and puts it successful nan cloud, nan strategy does present immoderate caller risks, but Google and Google Cloud Services already run galore end-to-end encrypted platforms for users, and Kleidermacher notes that nan expertise to create indelible logs that can't beryllium manipulated aliases deleted by a blase attacker is invaluable successful addressing targeted attacks.

“The main invention present is you person an audit log system to observe discuss that is really resistant to instrumentality tampering,” he says. “It's bringing intrusion discovery to nan consumer. So if you arsenic a user fishy a problem and you're not sure, you tin propulsion nan logs down from nan cloud. You tin stock them pinch a information expert, you tin stock them pinch an NGO, and they tin usage devices for analysis.”

Another characteristic that is connected by default and can't beryllium turned disconnected successful Advanced Protection is Android's Memory Tagging Extension (MTE). The feature, which debuted for Google's Pixel statement and is starting to beryllium adopted successful processors connected different devices, is simply a hardware information protection related to really a strategy manages its memory. If an attacker attempts to utilization a representation vulnerability specified arsenic a alleged buffer overflow, MTE will origin nan process to fail, stopping nan onslaught successful its tracks. Memory corruption bugs are a communal instrumentality utilized by hackers, truthful neutering nan full people of vulnerabilities makes it overmuch much difficult to onslaught a device.
