GhostSpider Backdoor: Understanding and Removing Trojan Horse Malware

Trojan horse malware, commonly referred to as “Trojans,” is a deceptive form of malicious software designed to infiltrate systems under the guise of legitimate programs or files. Named after the ancient Greek strategy of hiding soldiers inside a wooden horse to breach enemy defenses, Trojans exploit user trust to gain unauthorized access to systems. Once inside, they can execute a wide array of harmful activities, from stealing sensitive data to installing additional malware. Trojans, including the notorious GhostSpider Backdoor, often infiltrate systems through phishing emails, malicious downloads, or compromised websites. These threats pose significant risks to system integrity and user privacy, making it crucial to detect and remove them promptly.
