What does Bogus Websites mean?

The term "bogus website" is an informal term usually applied to a few different kinds of websites:

1) a website that is set up to mimic a legitimate website of an entity - perhaps a site meant to fool people into thinking they have reached their bank's web site. This kind of bogus web site is frequently used by miscreants who are conducting phishing attacks as a means of deceiving people into disclosing sensitive information that can be exploited for such nefarious purposes as stealing their identity, stealing money from them, stealing corporate information, or planting malware on their computers.

2) a website that is set up as a kind of Trojan Horse where people come thinking they are getting something but the jerk who set it up uses it to conduct a drive-by download of malware to the visitor's computer

3) a website that is set up to fool the user into thinking they are visiting a company or government website but which is actually being used to spread disinformation about the targeted entity. The creator(s) may conduct an attack to misdirect people to their bogus website instead of the correct website. This kind of website would probably fall under the category of either Propaganda or hacktivism.
