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.
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.
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.
