PlugX is a sophisticated type of remote access trojan (RAT) malware that allows cybercriminals to control infected computers from a distance. It is often used in targeted cyber espionage campaigns, enabling attackers to steal sensitive data, install additional malicious software, and manipulate system files without the victim's knowledge. PlugX is known for its stealthy techniques, such as hiding its presence and evading detection by security software. This malware typically spreads through phishing emails with malicious attachments or links, and is a favored tool among advanced persistent threat (APT) groups.
