Attackers can easily create radio interference to overshadow legitimate signals, leading to denial of service. The broadcast nature of radio signal propagation makes such attacks possible in the first place, but at the same time poses a challenge for the attacker: The jamming signal does not only reach the victim device but also other neighboring devices, preventing precise attack targeting. In this work, we solve this challenge by leveraging the emerging RIS technology, for the first time, for precise delivery of jamming signals. In particular, we propose a novel approach that allows for environment-adaptive spatial control of wireless jamming signals, granting a new degree of freedom to perform jamming attacks. We explore this novel method with extensive experimentation and demonstrate that our approach can disable the wireless communication of one or multiple victim devices while leaving neighboring devices unaffected. Notably, our method extends to challenging scenarios where wireless devices are very close to each other: We demonstrate complete denial-of-service of a Wi-Fi device while a second device located at a distance as close as 5 mm remains unaffected, sustaining wireless communication at a data rate of 25 Mbit/s. Lastly, we conclude by proposing potential countermeasures to thwart RIS-based spatial domain wireless jamming attacks. <p></p><center data-preserve-html-node="true"><br> <center data-preserve-html-node="true">———–<br> <center data-preserve-html-node="true"> <p></p><center data-preserve-html-node="true">ABOUT NDSS<br> <center data-preserve-html-node="true">The Network and Distributed System Security Symposium (NDSS) fosters information exchange among researchers and practitioners of network and distributed system security. The target audience includes those interested in practical aspects of network and distributed system security, with a focus on actual system design and implementation. A major goal is to encourage and enable the Internet community to apply, deploy, and advance the state of available security technologies. <p></p><center data-preserve-html-node="true"><br> <center data-preserve-html-node="true">———–<br> <center data-preserve-html-node="true"> <p></p><center data-preserve-html-node="true">Our thanks to the **[Network and Distributed System Security (NDSS) Symposium][1]** for publishing their Creators, Authors and Presenter’s superb **[NDSS Symposium 2025 Conference][2]** content on the **[organization’s’][1]** **[YouTube][3]** channel. <p></p></center></center></center></center></center></center></center></center></center></center></center></center></center></center></center></center></center></center></center></center></center></center></center></center></center></center></center></center></center><p><a href="https://www.infosecurity.us/blog/2025/11/18/ndss-2025-spatial-domain-wireless-jamming-with-reconfigurable-intelligent-surfaces">Permalink</a></p><p> </p><div class="spu-placeholder" style="display:none"></div><div class="addtoany_share_save_container addtoany_content addtoany_content_bottom"><div class="a2a_kit a2a_kit_size_20 addtoany_list" data-a2a-url="https://securityboulevard.com/2025/11/ndss-2025-spatial-domain-wireless-jamming-with-reconfigurable-intelligent-surfaces/" data-a2a-title="NDSS 2025 – Spatial-Domain Wireless Jamming With Reconfigurable Intelligent Surfaces"><a class="a2a_button_twitter" href="https://www.addtoany.com/add_to/twitter?linkurl=https%3A%2F%2Fsecurityboulevard.com%2F2025%2F11%2Fndss-2025-spatial-domain-wireless-jamming-with-reconfigurable-intelligent-surfaces%2F&linkname=NDSS%202025%20%E2%80%93%20Spatial-Domain%20Wireless%20Jamming%20With%20Reconfigurable%20Intelligent%20Surfaces" title="Twitter" rel="nofollow noopener" target="_blank"></a><a class="a2a_button_linkedin" href="https://www.addtoany.com/add_to/linkedin?linkurl=https%3A%2F%2Fsecurityboulevard.com%2F2025%2F11%2Fndss-2025-spatial-domain-wireless-jamming-with-reconfigurable-intelligent-surfaces%2F&linkname=NDSS%202025%20%E2%80%93%20Spatial-Domain%20Wireless%20Jamming%20With%20Reconfigurable%20Intelligent%20Surfaces" title="LinkedIn" rel="nofollow noopener" target="_blank"></a><a class="a2a_button_facebook" href="https://www.addtoany.com/add_to/facebook?linkurl=https%3A%2F%2Fsecurityboulevard.com%2F2025%2F11%2Fndss-2025-spatial-domain-wireless-jamming-with-reconfigurable-intelligent-surfaces%2F&linkname=NDSS%202025%20%E2%80%93%20Spatial-Domain%20Wireless%20Jamming%20With%20Reconfigurable%20Intelligent%20Surfaces" title="Facebook" rel="nofollow noopener" target="_blank"></a><a class="a2a_button_reddit" href="https://www.addtoany.com/add_to/reddit?linkurl=https%3A%2F%2Fsecurityboulevard.com%2F2025%2F11%2Fndss-2025-spatial-domain-wireless-jamming-with-reconfigurable-intelligent-surfaces%2F&linkname=NDSS%202025%20%E2%80%93%20Spatial-Domain%20Wireless%20Jamming%20With%20Reconfigurable%20Intelligent%20Surfaces" title="Reddit" rel="nofollow noopener" target="_blank"></a><a class="a2a_button_email" href="https://www.addtoany.com/add_to/email?linkurl=https%3A%2F%2Fsecurityboulevard.com%2F2025%2F11%2Fndss-2025-spatial-domain-wireless-jamming-with-reconfigurable-intelligent-surfaces%2F&linkname=NDSS%202025%20%E2%80%93%20Spatial-Domain%20Wireless%20Jamming%20With%20Reconfigurable%20Intelligent%20Surfaces" title="Email" rel="nofollow noopener" target="_blank"></a><a class="a2a_dd addtoany_share_save addtoany_share" href="https://www.addtoany.com/share"></a></div></div><p class="syndicated-attribution">*** This is a Security Bloggers Network syndicated blog from <a href="https://www.infosecurity.us/">Infosecurity.US</a> authored by <a href="https://securityboulevard.com/author/0/" title="Read other posts by Marc Handelman">Marc Handelman</a>.
