The Kasa Smart Wi-Fi Plug Mini (HS103) is a low-cost Wi-Fi plug controlled via the Kasa app and TP-Link cloud. In October 2026 TP-Link disclosed an improper-authentication flaw in the local management protocol of several Kasa devices, including HS103, and released firmware fixes. Earlier research on Kasa plugs found an unauthenticated local protocol with weak obfuscation. Positives are active vendor patching and a published security advisory. Summary：Initial classification of TP-Link Kasa Smart Plug Mini (HS103)
