Lockdroid’s text-to-speech unlocking

Catalin Cimpanu, for Bleeping Computer, details Lockdroid’s novel use of TTS functions as part of the post-payment unlocking process: Android Ransomware Asks Victims to Speak Unlock Code. Based on a report from Symantec that I haven’t seen yet.

Lockdroid’s current campaigns appear to be focused on China, but that doesn’t mean its innovations won’t be seen elsewhere. Symantec’s Dinesh Venkatesan noted implementation bugs and that it might be possible for a victim to recover the unlock code from the phone.
