Peilusivusto

Peilusivusto is a Finnish term that translates to "mirror site" or "clone site." It refers to a replica of an existing website, hosted on a different domain or server. These sites are often created for various purposes, some legitimate and others malicious.

Legitimate uses of mirror sites can include improving website performance by distributing traffic across multiple servers, providing access to content in regions with slow internet speeds, or creating backups in case the primary site experiences downtime. Academic institutions and large organizations sometimes employ mirror sites for research or data distribution.

However, the term "peilusivusto" is frequently associated with illicit activities. Malicious mirror sites are often created to impersonate legitimate websites, such as banks, e-commerce platforms, or social media sites, in order to steal user credentials through phishing. They can also be used to distribute malware or spread misinformation. Identifying a peilusivusto often involves checking the URL for subtle differences from the official site, looking for inconsistencies in design or content, and being cautious about unsolicited links. The intent behind a peilusivusto can range from harmless duplication to serious cybercrime.
