Praeda is a ‘automated printer data harvesting tool’ written in Perl. It was developed to better understand the risks associated with multi-function printers, and to help penetration testers gather usable data during security assessment job. Praeda consists of several modules to exploit weaknesses in various printer models. Praeda systematically collects sensitive information from the printer's embedded web server. Besides exploiting vulnerabilities that lead to disclosure of device passwords, the tool gathers usernames and email addresses, which are often publicly available via the printer's web interface and can be used for further network penetration tests.
