Digging little of the company responsible of the WOT reveals the following: - WOT Services Oy started in 9 July 2009 - Both founders (Sami Tolvanen and Timo Ala-Kleemola) left 2014 - WOT Services Oy changes name to TOW Software Oy in 18 Feb 2016 and is liquidated since 30 June 2016 So if the company has been liquidated since 30 June then how can the page www.mywot.com still be up and running? Who owns the company now? Giving command whois mywot.com gives registrar info as tucows Also of interest: https://gist.github.com/Rob--W/bda5f28a0ac3b877780c6665bbed2e1b "Subject Add-on: Web of Trust, MyWOT/WOT: Website Reputation Rating Version: 20151208 URL: https://addons.mozilla.org/en-us/firefox/addon/wot-safe-browsing-tool/ First seen in version: 20090918 (version notes: "Added support for content scripts on search results pages") Summary The WOT add-on can execute arbitrary code on any page, including privileged browser pages. Impact and severity: Critical. If WOT wants to, they can do anything ranging from stealing banking credentials to installing malware on the user's computer. At the time of analysis, this functionality was not abused" So since 2009 the WOT could, if they wanted to, have totally hijacked your computer? And the last open source version you can find from https://github.com/mywot is from 2015? This whole thing is so shady that I wouldn't touch this extension with 10 foot pole. Happy New Year!
