What began as an extra tool for smartphones has evolved into independent gadgets with a more advanced voice system, which has become another indispensable tool for brands, in addition to the fact that there are already several brands for home use on the Uganda Mobile Database market. What began as an extra tool for smartphones has evolved into independent gadgets with a more advanced voice system, which has become another indispensable tool for brands, in addition to the fact that there are already several brands for home use on the market. Among the various brands such as Siri, Apple, Amazon’s Alexa, Microsoft’s Cortana, and Google Assistant, they developed complex artificial intelligence systems, whose voice functions were always sold as “anti-hackable”, until Chinese researchers discovered a vulnerability in voice assistants from Apple, Google, Amazon, Microsoft, Samsung, and Huawei.
According to The Guardian, researchers from Zhejiang University designed a technique called “Dolphin Attack” , which translated various voice commands into ultrasonic frequencies, which are decipherable by the software that powers the voice assistants, that is, this process it would allow hackers to take control of gadgets with just a few words spoken at frequencies that people cannot hear.
Apparently, the vulnerability in the voice command software would also affect iPhones, Macbooks running Siri, as well as Galaxy models, Samsung models, and even Windows 10 computers. According to Asian researchers, they could ask a Macbook or Nexus 7 open a malicious website.
Specifically, to hack a voice assistant, the Brother Cell Phone List researchers used a Smartphone, plus a loudspeaker, as well as additional hardware to “manipulate the command of voice frequencies” so that when manipulating the voice assistants they could install malicious code, or malware on people’s gadgets. For computer analysts, the design of microphones’ voice assistants’ make it difficult to protect themselves from these types of attacks, since the components of their microphones use components that cannot be blocked by ultrasound.
