They seem pretty sure about it:

"The communication protocol used for this communication is Extensible
Messaging and Presence Protocol (XMPP). XMPP implements Simple
Authentication and Security Layer (SASL) and Transport Layer Security
(TLS) for its security. This means that MitM attack might be feasible for
this communication"
