Serious Android crypto key theft vulnerability affects 10% of devices
Researchers have warned of a vulnerability present on an estimated 10 percent of Android phones that may allow attackers to obtain highly sensitive credentials, including cryptographic keys for some banking services and virtual private networks, and PINs or patterns used to unlock vulnerable devices.
The vulnerability resides in the Android KeyStore, a highly sensitive region of the Google-made operating system dedicated to storing cryptographic keys and similar credentials, according to an advisory published this week by IBM security researchers. By exploiting the bug, attackers can execute malicious code that leaks keys used by banking and other sensitive apps, virtual private network services, and the PIN or finger patterns used to unlock handsets.
