What is Addoncrop?

Addoncrop is a collection of browser plugins that allow users to download multimedia content from streaming platforms. At the time of writing, it supports this feature for such immensely popular services as YouTube, SoundCloud, and Dailymotion. Moreover, there are quite a few different video quality parameters, formats, and conversion bitrates to choose from. It’s worth mentioning separately that this functionality actually works and fills the void for numerous users who wish to store these materials locally. So much for the good part. People who rush headlong into enhancing their media experience with Addoncrop bump into several caveats. First of all, downloading copyright-protected materials off of the likes of YouTube is prohibited by law. This is clearly at odds with the provisions of the Digital Millennium Copyright Act (DMCA). In case the content is both stored on hardware media and redistributed, the upshot can be double trouble and the penalties can range from a huge fine all the way to a jail sentence.

Addoncrop YouTube Video Downloader page doesn’t mention any pitfalls whatsoever

The legal facet of this matter is definitely on the minus side of services like Addoncrop, and therefore users should think twice before opting in. This, however, doesn’t keep such tools from gaining traction among video and music fans around the world; moreover, they aren’t being taken down or otherwise disrupted, no matter how counterintuitive this might sound. Whilst the regulation-related controversy is obvious, this isn’t the only pitfall regarding Addoncrop. Another element of its flip side is that it often arrives with potentially unwanted components that behave much like your garden-variety adware. The scheme that backs this foul play is known as bundling. It denotes a logic where a harmless product is distributed alongside extras the user is unaware of. Most of the time, this hoax relies on the default (express, recommended) installation option lure. It’s supposed to make the software setup faster and easier, but chances are that it conceals malicious items under its hood.

The dubious programs that often accompany Addoncrop gain a foothold in the user’s web browser without their express consent. They may forcibly modify the web navigation preferences such as the search engine, homepage, and new tab page. This trick entails incessant redirecting to sketchy resources via auxiliary URLs such as xfreeservice.com or adrail.com. These inconspicuous “touches” of the traffic during the Internet surfing help malware authors rake in profits as these hits count in an online monetization scheme. Regular users will be most likely ending on the intended sites in the long run, but it will take the browser more time to load them because of the “paddings” inserted in between without permission.

Addoncrop is downloadable via a third-party service called CrossPilot

To top it off, this activity tends to be associated with privacy encroachments down the road. The adware monitors the victims’ traffic patterns to profile them and align subsequent malicious advertising (malvertising) with these unique peculiarities. This is exactly what allows disreputable data aggregates to stay afloat, the major nuance being that unsuspecting users’ personally identifiable information (PII) is collected and processed behind their backs. Many users who added the Addoncrop plugin to their browsers start experiencing recurrent popups being opened on their own in new tabs or in the form of full-page adverts. These landing pages typically reflect some information the victims have recently looked up on a search engine or explored by visiting certain sites. This, gain, is a giveaway of questionable data harvesting implemented by the service under scrutiny.

There is one more thing that may raise a red flag. When users actually want to embed Addoncrop into, say, Google Chrome to download videos from streaming portals, they cannot install it via the browser’s official marketplace. It’s simply not listed there. Instead, the official website of this tool forwards people to a page for a third-party service called CrossPilot. Another option is to go for a “developer mode install”, which appears somewhat suspicious as well. The vendor might be using these workarounds to avoid bans or suchlike hindrance from the authorities or legit providers, and it’s also something to consider for those who keep Addoncrop on their wish list. If this extension is already running on a PC and its emergence has co-occurred with dodgy browser redirects and numerous ads appearing where they don’t belong, the following steps will help get rid of the malicious interference.
