The integration of large language models (LLMs) into information retrieval systems introduces new attack surfaces, particularly for adversarial ranking manipulations. We present StealthRank, a novel adversarial ranking attack that manipulates LLM-driven product recommendation systems while maintaining textual fluency and stealth. Unlike existing methods that often introduce detectable anomalies, StealthRank employs an energy-based optimization framework combined with Langevin dynamics to generate StealthRank Prompts (SRPs)-adversarial text sequences embedded within product descriptions that subtly yet effectively influence LLM ranking mechanisms. We evaluate StealthRank across multiple LLMs, demonstrating its ability to covertly boost the ranking of target products while avoiding explicit manipulation traces that can be easily detected. Our results show that StealthRank consistently outperforms state-of-the-art adversarial ranking baselines in both effectiveness and stealth, highlighting critical vulnerabilities in LLM-driven recommendation systems.

This year finds us in a much different place than last. Instead of hunkering down for a chilly, lonely winter, we're flinging aside our face masks and getting ready to return to the outside world. However, if you're having friends over for the first time in more than a year, you might still need help vacuuming the living room carpet. Or maybe you're styling your hair to appear in public for the first time in a loooong time and have forgotten how to do it! If that's the case, we can help! We perused all of Amazon's Prime Day deals for the second day to find the best ones for you, your kids, and your dusty corners and kitchen counters. Note: We regularly update articles and strike through items that sell out or rise in price as of publishing, and mark discounts based on recent product pricing or average price, not MSRP.

In the universe of disruptive technologies, artificial intelligence is one of the deepest, most durable themes, and that status is meaningful to strategies like the ARK Autonomous Technology & Robotics ETF (CBOE: ARKQ). ARKQ holdings "are focused on and are expected to substantially benefit from the development of new products or services, technological improvements and advancements in scientific research related to, among other things, energy, automation and manufacturing, materials, and transportation," according to ARK Invest. What makes AI an exciting investment prospect is its intersection with other disruptive growth themes. "We believe that since AI is embedded in many products and services, the cost and latency of running compute tasks on data center servers are more relevant and could become prohibitive," states ARK research. "Jem Davies, an ARM fellow, highlighted this point by explaining how a voice-enabled coffee maker could consume up to $15 a year in cloud computing costs. For applications like self-driving in which the decision time is critical, the latency and cost associated with servers hundreds of miles away could become life-threatening."

One of the best things about Amazon Alexa is that she can make life easier by helping you prepare for the day ahead. She read you the forecast, remind you of upcoming meetings, and much more. Now she can brew you a pot of coffee before you ever leave the bed. Like many people, coffee is essential for making my mornings run smoothly. While living in quarantine with my two young kids, I'm always looking for ways to automate my morning and make life less hectic, like letting Alexa brew me up a pot of the good stuff.

The Internet of Things is gradually penetrating every aspect of our lives. With the growth in numbers of internet-connected sensors built into cars, planes, trains, and buildings, we can say it is everywhere. Be it smart thermostats or smart coffee makers, IoT devices are marching ahead into mainstream adoption. But, these devices are far from perfect. Currently, there is a lot of manual input required to achieve optimal functionality -- there is not a lot of intelligence built-in.

Alexa, are you eavesdropping on me? I passive-aggressively ask my Amazon Echo this question every so often. Because as useful as AI has become, it's also very creepy. And this, of course, produces privacy nightmares, as when Amazon or Google subcontractors sit around listening to our audio snippets or hackers remotely spy on our kids. The problem here is structural.
