The key is stored using a reversible encoding scheme. An attacker who obtains access to a deployed client configuration file can decode the stored value to recover the plaintext Gateway Key. Possession of the Gateway Key allows unauthorized access to NetSupport Manager connectivity services and enables remote control of systems managed through the same key.
