Crumbling Walls – Wiki

Consumer spyware, also stalkerware, or spouseware, is a malware family that can be used to spy on domestic targets such as family members, partners, and spouses. With $50 USD to $200 USD for a monthly or yearly subscription the software is relatively cheap. It can be installed on cellphones and other computers to intercept calls, chat messages in applications like Facebook, WhatsApp or iMessage, remotely switch on a phone's microphone, submit a phone's location by reading its GPS data, and capture a user's web browsing history.

In a recent security breach of two vendors of such software, http://www.retinax.com/ and http://flexispy.com/, names and email addresses of 130.000 users were leaked.
