OpenCandy

Last updated

OpenCandy was an adware module and a potentially unwanted program classified as malware by many anti-virus vendors. [1] [2] [3] [4] They flagged OpenCandy due to its undesirable side-effects. [5] [6] It was designed to run during installation of other desired software. Produced by SweetLabs, it consisted of a Microsoft Windows library incorporated in a Windows Installer. When a user installed an application that had bundled the OpenCandy library, an option appeared to install software it recommended based on a scan of the user's system and geolocation. Both the option and offers it generated were selected by default and would be installed unless the user unchecked them before continuing with the installation. [7] [8]

Contents

OpenCandy's various undesirable side-effects included, changing the user's homepage, desktop background or search provider, inserting unwanted toolbars, plug-ins and extension add-ons in the browser. It also collected and transmitted various information about the user and their Web usage without notification or consent. [1] [9] After massive criticism of the software occurred, it was eventually discontinued in August of 2016.

Development

The software was originally developed for the DivX installation, by CEO Darrius Thompson. When installing DivX, the user was prompted to optionally install the Yahoo! Toolbar. DivX received $15.7 million during the first nine months of 2007 from Yahoo and other software developers, after 250 million downloads. [8]

Chester Ng, the former DivX business development director, is chief business officer and Mark Chweh, former DivX engineering director, is chief technology officer. [8]

Workarounds

There were workarounds to bypass OpenCandy by running some installers with a /NOCANDY parameter on the command line, which was up to the installer to support or not. [39]

Download Valley is a cluster of software companies in Israel, producing and delivering adware to be installed alongside downloads of other software. The primary purpose is to monetize shareware and downloads. These software items are commonly browser toolbars, adware, browser hijackers, spyware, and malware. Another group of products are download managers, possibly designed to induce or trick the user to install adware, when downloading a piece of desired software or mobile app from a certain source.

A potentially unwanted program (PUP) or potentially unwanted application (PUA) is software that a user may perceive as unwanted or unnecessary. It is used as a subjective tagging criterion by security and parental control products. Such software may use an implementation that can compromise privacy or weaken the computer's security. Companies often bundle a wanted program download with a wrapper application and may offer to install an unwanted application, and in some cases without providing a clear opt-out method. Antivirus companies define the software bundled as potentially unwanted programs which can include software that displays intrusive advertising (adware), or tracks the user's Internet usage to sell information to advertisers (spyware), injects its own advertising into web pages that a user looks at, or uses premium SMS services to rack up charges for the user. A growing number of open-source software projects have expressed dismay at third-party websites wrapping their downloads with unwanted bundles, without the project's knowledge or consent. Nearly every third-party free download site bundles their downloads with potentially unwanted software. The practice is widely considered unethical because it violates the security interests of users without their informed consent. Some unwanted software bundles install a root certificate on a user's device, which allows hackers to intercept private data such as banking details, without a browser giving security warnings. The United States Department of Homeland Security has advised removing an insecure root certificate, because they make computers vulnerable to serious cyberattacks. Software developers and security experts recommend that people always download the latest version from the official project website, or a trusted package manager or app store.
