Hidden voice commands could hijack smartphones

Borg-like voice commands from your phone could take control of nearby Android devices using a newly demonstrated voice recognition vulnerability.

Security researchers have discovered a way of hiding voice commands in online videos that could take control of smartphones and tablets.

In a paper, researchers described how a voice recognition feature, such as Google Now, Siri or Cortana can be abused. In a YouTube video, the researchers demonstrated a proof-of-concept attack against an Android smartphone.
