Answer:
Systems locked with malware can be rendered unusable until demands for digital payment are made.
Explanation:
The main risk of online communication is that everyday more and more vital information to the public is storaged online, and in this case the risk of having all of that sensitive information up in the net is the fact that some systems are vulnerable to malware and can be held hostage, either the systems or the information and then ask for payment that can be untrackable, all of this from a secure location that has internet or satellital access to internet.
