GoPIX is a malicious program targeting the Pix instant payment platform in Brazil. It operates as a clipper designed to reroute Pix and cryptocurrency transactions, posing significant financial and privacy risks. In this comprehensive removal guide, we will explore the threat type, detection names, distribution methods, and the steps to remove GoPIX from your system.
GoPIX is classified as a Trojan, specifically a clipper, which replaces data in the clipboard to reroute transactions and steal information.
A Trojan, often referred to as a “Trojan horse,” is a type of malicious software (malware) that disguises itself as a legitimate and benign program or file to deceive users and gain unauthorized access to their computer systems. The name “Trojan horse” is derived from Greek mythology, where the Greeks used a large wooden horse to infiltrate the city of Troy. Similarly, a Trojan malware disguises its true malicious intent to infiltrate a computer or network.
Here are key characteristics of a Trojan:
- Deception: Trojans are designed to trick users into believing they are harmless or useful software. They often masquerade as legitimate programs, games, or files that users might willingly download or execute.
- Malicious Intent: Once a Trojan gains access to a system, it can carry out a wide range of harmful actions, depending on its specific type and purpose. Common actions include stealing sensitive data, providing remote access to attackers, damaging files, installing other malware, or creating backdoors for future attacks.
- Non-Self-Replicating: Unlike computer viruses, Trojans do not self-replicate or spread on their own. They rely on human actions, such as downloading and executing a file, to propagate.
- Diverse Types: There are numerous types of Trojans, each designed for specific purposes. Some common types include remote access Trojans (RATs), keyloggers, banking Trojans, and spyware.
- Payload: The “payload” of a Trojan is the specific malicious action it carries out. Trojans can have various payloads, including data theft, system damage, or serving as a delivery mechanism for other malware.
- Stealth: Trojans often attempt to hide their presence on a system by evading detection from antivirus and security software.
- Delivery Methods: Trojans can be distributed through various means, such as email attachments, software downloads, fake software updates, or malicious websites.
