Google just dropped a bombshell for app developers with the latest version of its Android mobile operating system. The company can now prevent apps from installing if they try to use the system’s accessibility features.

The new development, live in version 17.2 of Android, is all about security, explains the company. It stops certain kinds of apps from using the accessibility service if Advanced Protection Mode (APM) is enabled.

The accessibility API lets app developers support users living with disabilities who need extra help using their phones. Apps can use this API to access the screen in unique ways, control input for the user, and use voice services, for example.

Sadly, as with most useful tools, someone will always find a way to misuse it and ruin it for everyone else. Malware developers have been using this API for years as a way into your bank account. The accessibility service has a lot of power: Any app with permissions to use it can read what’s on your screen.

Many Android banking Trojans are little more than accessibility API wrappers with criminal intent. They steal 2FA codes, impersonate victims, and drain accounts while victims sleep.

Two tricks dominate. The first is fake overlays. The accessibility API lets you put overlays on top of another app’s screen. Banking and cryptocurrency Trojan developers can use this to capture your keystrokes (you think you’re just logging into your banking app, but malware is collecting everything you type).

The second is permission abuse. Once the Trojan has your passwords, it can authorize its own transactions.

The number of malware frameworks taking advantage of the accessibility API has grown. DroidLock uses it to steal your personal data before demanding a ransom. Albiriox uses it to install itself and give remote control to attackers halfway around the world.

We saw both in December, and just last month Malwarebytes researcher Stefan Dasic noticed an accessibility service-abusing malware program posing as a fake Google Security page.

Google’s nuclear option

Google has tried before to curb misuse of the API. In 2017, it warned developers to justify their use of accessibility features or risk removal from the Play Store. Developers revolted, and Google relented. But then, in November 2021, it began demanding permission forms for accessibility API usage for Android 12+ apps.

Now the company is getting tougher still, enforcing stricter accessibility API rules. Apps can no longer freely enable accessibility services using a simple software flag. Instead, only apps whose core purpose is accessibility will be allowed to use it.

Google’s examples include screen readers, switch inputs, voice controls, and Braille displays. With these new rules, password managers or automation apps aren’t getting to the accessibility API anymore.

At least, not if the user has APM turned on.

Launched in May last year, APM is Google’s version of Apple’s Lockdown Mode. It introduces far tighter security controls for people who switch it on, making it harder for malware to exploit them.

The trade-off for that extra security is more limited functionality. For example, only apps from trusted sources will install, and data transfer via USB is restricted. Accessibility API access is now restricted too.

So now, you can be a password manager or an accessibility tool, but not both. Developers relying on accessibility for convenience features will need to find another way.

This is Google acknowledging that some APIs are too dangerous to leave open, even if some legitimate apps suffer. The company is betting that most users care more about not getting robbed than having their password manager use the accessibility API for convenience.

Malware authors will adapt, as always. But for now, Google just made phones with APM turned on a lot harder to mess with.
