Google on why it decided to offer 7 years of Android, security updates on Pixel 8 series


Google Pixel 8 series launch announcement was a bit of a sweet surprise for potential buyers as the company promised 7 years of OS and security updates. Apart from a bunch of AI magic tricks and quarterly feature drops, Google went ahead with this USP to make Pixel phones stand-out from a sea of Android smartphones. Recently, one of the company executives spoke about it and why it was done.

Seang Chau, vice president – Devices & Services Software, said during a podcast that Google has active user data of its Pixel users which suggests that most people use one model for multiple years.

“So when we look at the trajectory of where the original Pixel that we launched in 2016 landed and how many people were still using the first Pixel, we saw that actually, there’s quite a good active user base until probably about the seven-year mark,” Chau said.

According to the executive, when Google realised that people have been using the phones for as long as six years, the company decided that it will support Pixel 8 and later models with a total of 7 years of OS and security updates.

How Google is able to promise this change
One of the major changes that Pixel smartphones have seen since Pixel 6 onwards is the Tensor SoC – designed by Google to undertake AI tasks and machine learning models, giving it a better control on features.

But 7 years is a long time in the smartphone industry, and to tackle hardware limitations, Chau said that by keeping features software-based, Google aims to extend the usability of older devices, allowing them to benefit from new features without needing hardware upgrades.

Recently, it was announced that Pixel 8 is also going to get some AI features that were available on Pixel 8 Pro.

Google Revealed Kernel Address Sanitizer To Harden Android Firmware


Android devices are popular among hackers due to the platform’s extensive acceptance and open-source nature.

However, it has a big attack surface with over 2.5 billion active Android devices all over the world.

It also poses challenges when it comes to prompt vulnerability patching due to its fragmented ecosystem that consists of different hardware vendors and delayed software updates.

Malware distribution, surveillance, and unauthorized financial gain, or any other malicious purpose are some examples of how cybercriminals take advantage of these loopholes in security.

Recently, Google unveiled the Kernel Address Sanitizer (KASan) to strengthen the Android firmware and beyond.

Android Firmware And Beyond

KASan (Kernel Address Sanitizer) has broad applicability across firmware targets. Incorporating KASan-enabled builds into testing and fuzzing can proactively identify memory corruption vulnerabilities and stability issues before deployment on user devices.

Watch out — that free Android VPN app could hijack your device


Almost two dozen free Android VPN apps were actually turning host devices into residential proxies, researchers have revealed announced. All of the apps were subsequently removed from the Play Store, with some making a comeback after cleaning up their code.

Cybersecurity researchers from HUMAN’s Satori Intelligence Team recently discovered a total of 28 apps, all of which had the “Proxylib” software development kit (SDK). This SDK, built in the Golang programming language, was designed to do the proxying, a process in which internet traffic is routed through third-party devices.

Second Android 15 preview bolsters security to safeguard your files


What you need to know

  • Further digging into Google’s second Android 15 preview shows increased security efforts to protect devices connected via USB.
  • When attempting to switch USB modes, users will have to verify that it is them through various lock screen security methods.
  • Google detailed its second Android 15 preview yesterday (Mar. 21), offering insight into its satellite connectivity and more.

Google’s latest Android 15 preview gives users better insight into how it will protect your files when connected via USB.

According to Mishaal Rahman (Android Police), Android 15 Developer Preview 2 shows the software will require more “authentication” during USB-connected moments. To change which USB mode you’re in, Rahm discovered users must verify it’s truly them via lock screen measures such as their PIN, fingerprint, pattern, or password.
