What is:Creepware/pt

O que é "Creepware"

Creepware (também conhecido como trojan de acesso remoto ou RAT) é Software malicioso que é instalado no dispositivo da vítima sem o conhecimento deles e permite que um invasor acesse e controle o dispositivo invadido (computador, tablet, laptop, smartphone ou outro dispositivo, por exemplo, IoT - Internet of things) remotamente.

The acronym RAT can be an abbreviation for Remote Access/Administration Trojan (trojan with remote access/administration functions), and for Remote Access/Administration Tool (tool for remote access/administration). The difference between remote access tools and remote access trojans is that the latter are installed secretly and used for illegal and/or malicious purposes, while remote access tools are used for authorized actions and for legitimate purposes, such as technical support, connecting to your home or workplace computer while traveling, etc.

How creepware works

Creepware uses a model of work called client-server, but it distorts the usual idea of how this model works, i.e. when a user connects to a server that provides some kind of service. In the case of creepware, the victim's device becomes a server, and the attacker's device works as a client. The "service" provided to the attacker are information or unauthorized actions on the victim's device.
