Impact

The deriveVaultKey function calls retrieveCloudKey which always returns "foobarfoobarfoobarfoobarfoobarfo". When merged with the randomly generated 32-byte key using mergeKeys (16 bytes from each), the last 16 bytes are always "arfoobarfoobarfo". This enables an attacker with physical access to the EVE-OS device to attempt to brute force the remaining 128 bits of key.
