Unauthorized entry via cloned unencrypted RFID tag
Published Aug 15, 2023 · Updated Oct 8, 2024
Missing encryption in the RFID tag of Suleve 5-in-1 Smart Door Lock 1.0 allows physically proximate attackers to clone access tags. The lock relies on a low-frequency RFID tag that exposes only an unencrypted numeric identifier, which a phone or reader can capture in under a second and write to a blank tag. Brief proximity to the original tag is required; the duplicate inherits the original tag's permissions and can unlock the protected door without alerting its owner.
