No matter how convenient it is to watch multimedia materials on the go, users may want to store some of their favorite content on a hard drive. This could be due to one’s old-fashioned mindset or a desire to watch and listen to stuff when offline. Whatever the reasoning is, lots of people are looking for solutions that allow them to achieve such a goal. This is a classic example of demand causing supply, with numerous online video downloaders being available on the Internet. is one of these services. It claims to help users download streaming videos and music for free. An extra catch is that the feature isn’t restricted to YouTube only, so it’s allegedly possible to pull in content from many other sites that operate in a similar way, such as Vimeo and Dailymotion. According to the developer, all it takes is entering the URL of the video or soundtrack prepended with the “ss” string in the appropriate box on their web page, and then hitting Enter. One more option is to install a browser add-on that does the download job automatically. This sounds like a good deal for those interested, but there is a pitfall.

Controversial service asking a Mac user to allow notifications

The first red flag that shows up right after visiting the site in question is that it displays a popup asking the user to allow notifications. What does it mean? This is about entities called web push notifications, which is a growingly popular way to conduct marketing campaigns. It is generally a benign technology that enables web page owners to provide their target audience with a news feed via popup boxes appearing even outside the browser. Meanwhile, there are common concerns about the intrusive effects related to this tactic. The issue gets particularly acute when unscrupulous service providers enter the game.

The information on the resulting pages may be camouflaged as media that won’t play unless the victim opts for notifications from yet another site. In the worst-case scenario, the traffic can be rerouted to a tech support scam stating that the Mac is infected with viruses and coercing the visitor to scan their system and then install a piece of scareware masqueraded as an antivirus tool.

According to recent findings of security analysts, the Helper browser extension added by this service to purportedly facilitate online video and soundtrack downloads poses a serious risk to one’s privacy. This dubious add-on reportedly harvests a plethora of personally identifiable information that’s not isolated to the browsing history log. The sensitive data collected by this app additionally includes GPS location, usernames, passwords, credit card details, tax returns, and more. In light of this discovery, the extension was expelled from the official web stores of the top web browsers. It’s still available on the publisher’s website, though.

At the end of the day, the offensive traits of service turns out to outstrip the useful ones. It swamps the Mac user’s experience with irritating ads, forwards their browser to sketchy sites, and steals personal info that can play into cybercriminals’ hands. Obviously, it’s best to stay away from its aggressive marketing.
