While it may appear to perform a beneficial or benign function, it secretly executes harmful actions in the background without the user&#8217;s knowledge. The name \u201cTrojan horse\u201d comes from the ancient Greek myth in which Greek soldiers hid inside a wooden horse to gain entry into the city of Troy, paralleling how Trojan malware hides its true intent.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How It Works:<\/h3>\n\n\n\n<p>When a user downloads or installs a Trojan horse, they often believe it&#8217;s a legitimate file \u2014 such as a software update, a game, or a document. Once executed, the Trojan may:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Install other types of malware (like spyware or ransomware)<\/li>\n\n\n\n<li>Create a backdoor for hackers to access the system remotely<\/li>\n\n\n\n<li>Steal sensitive data such as passwords or banking details<\/li>\n\n\n\n<li>Corrupt or delete files<\/li>\n\n\n\n<li>Monitor user activities via keystroke logging or screen capture<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Why It&#8217;s Dangerous:<\/h3>\n\n\n\n<p>Trojan horses are especially dangerous because they rely on <strong>social engineering<\/strong> \u2014 tricking users into voluntarily installing them. Unlike viruses or worms, Trojans do not replicate themselves but are instead manually executed by unsuspecting users.<\/p>\n\n\n\n<p>They often evade security mechanisms by:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Embedding within trusted files<\/li>\n\n\n\n<li>Exploiting software vulnerabilities<\/li>\n\n\n\n<li>Disabling antivirus software once installed<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Prevention:<\/h3>\n\n\n\n<p>To avoid Trojan horses, users should:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Avoid downloading files or clicking links from unknown sources<\/li>\n\n\n\n<li>Keep antivirus software and operating systems up to date<\/li>\n\n\n\n<li>Use firewalls and intrusion detection systems<\/li>\n\n\n\n<li>Verify the source and integrity of downloaded applications<\/li>\n<\/ul>\n\n\n\n<p>In summary, a <strong>Trojan horse<\/strong> is a deceptive and dangerous program that tricks users by pretending to be useful while carrying hidden malicious actions, posing a serious threat to computer security.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>A _ is a computer program that appears to have a useful function, but also has a hidden and potentially malicious function that evades security mechanisms The correct answer and explanation is: Correct Answer: Trojan horse A Trojan horse is a type of malicious software (malware) that disguises itself as a legitimate or useful program [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[],"class_list":["post-20294","post","type-post","status-publish","format-standard","hentry","category-quiz-questions"],"_links":{"self":[{"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/posts\/20294","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/comments?post=20294"}],"version-history":[{"count":1,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/posts\/20294\/revisions"}],"predecessor-version":[{"id":20295,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/posts\/20294\/revisions\/20295"}],"wp:attachment":[{"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/media?parent=20294"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/categories?post=20294"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/tags?post=20294"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
