 ### Delete Keys via kms:DeleteImportedKeyMaterial
 
-With the `kms:DeleteImportedKeyMaterial` permission, an actor can delete the imported key material from CMKs with `Origin=EXTERNAL` (CMKs that have imperted their key material), making them unable to decrypt data. This action is destructive and irreversible unless compatible material is re-imported, allowing an attacker to effectively cause ransomware-like data loss by rendering encrypted information permanently inaccessible.

 **Impact:** Direct privilege escalation by assuming another user's extended permissions.
 
+Note that a user can only have 2 access keys created, so if a user already has 2 access keys you will need the permission `iam:DeleteAccessKey` to detele one of them to be able to create a new one:

+If you can create a new virtual MFA device and enable it on another user, you can effectively enroll your own MFA for that user and then request an MFA-backed session for their credentials.
+
+**Exploit:**
+
+```bash
+# Create a virtual MFA device (this returns the serial and the base32 seed)
+aws iam create-virtual-mfa-device --virtual-mfa-device-name <mfa_name>
+
+# Generate 2 consecutive TOTP codes from the seed, then enable it for the user
+aws iam enable-mfa-device --user-name <target_user> --serial-number <serial> \
