Malexa is an intelligent voice assistant with a simple and seemingly legitimate third-party skill that delivers news briefings to users. The twist, however, is that Malexa covertly rewords these briefings to introduce misperception about the reported events intentionally. This covert rewording is what we call an Ambient Tactical Deception (ATD) attack. It differs from squatting or invocation hijacking attacks in that it is focused on manipulating the “content” instead of the “invocation logic.” Malexa dynamically manipulates news briefings to make a government response sound more accidental or lenient than the original news delivered by Amazon Alexa. A study with 220 participants was conducted to assess Malexa’s effect on inducing misperceptions and covert manipulation of reality. We found that users who interacted with Malexa perceived that the government was less friendly to working people and more in favor of big businesses, regardless of their political ideology or frequency of interaction. These findings express the potential of Malexa becoming a covert “influencer” aiming to disrupt the current political climate, particularly the build-up to the 2020 presidential elections in the United States.
