Is an unknown MDM Certificate on a used iPhone a security risk?

2 pointsby sysrplover 2 years ago
Recently I bought a used iPhone for my daughter. After a factory reset, I went into its settings and noticed it still has an MDM certificate installed from the previous owner. For whatever reason, I am having difficulty removing this certificate and I would like to know if leaving this certificate on this iPhone would pose any danger, such as a remote takeover or leaking any of my daughter&#x27;s information either to the original owner or a third party.<p>Is leaving an unknown MDM certificate from the previous owner on an iPhone a security risk? If so what is the best way to remove it?

According to Apple<p>&gt; 1. All profiles can be removed by wiping the device of all data. [0]<p>Depending on the MDM profile there&#x27;s a lot that can be done. Is the profile still active or just the certificate is hanging around?<p>[0]: <a href="https:&#x2F;&#x2F;support.apple.com&#x2F;en-ca&#x2F;guide&#x2F;deployment&#x2F;depc0aadd3fe&#x2F;web" rel="nofollow">https:&#x2F;&#x2F;support.apple.com&#x2F;en-ca&#x2F;guide&#x2F;deployment&#x2F;depc0aadd3f...</a>
