The keyfob subsystem in Honda Civic 2012 vehicles allows a replay attack for unlocking. This is related to a non-expiring rolling code and counter resynchronization.
The remote keyless system on Honda Civic 2018 vehicles sends the same RF signal for each door-open request, which allows for a replay attack, a related issue to CVE-2019-20626.
Medtronic MiniMed MMT devices when paired with a remote controller and having the “easy bolus” and “remote bolus” options enabled (non-default), are vulnerable to a capture-replay attack. An attacker can capture the wireless transmissions between the remote controller and the pump and replay them to cause an insulin (bolus) delivery.
