Apa itu Creepware

Creepware (juga dikenal sebagai trojan akses jarak jauh atau RAT) adalah Perangkat lunak berbahaya yang diinstal pada perangkat korban tanpa sepengetahuan mereka dan memungkinkan penyerang mengakses dan mengontrol perangkat yang diretas (komputer, tablet, laptop, ponsel cerdas atau perangkat lain, misalnya, IoT - Internet of things) jarak jauh.

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.

What are the features of creepware?

Creepware provides the attacker with access to the following elements on a compromised device:

• files;
• processes and services;
• clipboard;
• network connections;
• registry;
• connected peripherals (printers, webcams, audio recording devices, etc.).

In addition, creepware allows the attacker to remotely monitor the compromised device, namely:

• keep a log of keystrokes pressed;
• take screenshots of the screen;
• record video from the connected webcam;
• record audio from the connected microphone;
• steal passwords;
• download and upload files from/to the device;
• open web pages;
• display messages on the screen;
• play audio messages;
• reboot or turn off the compromised device.
