This is a political article (so it will probably get flagged, removed and downvoted) but, it relates to security and encryption, so I submitted it anyway

from the article:

> WebEx, a communications program from U.S.-based Cisco Systems, provides end-to-end encryption which allows for secure communications. However, if a participant dials in via a landline rather than using the app — as apparently happened in the case of the officer in Singapore — then the encryption is not guaranteed.
