The latest case of Windows Movie Maker scam involves cyber-criminals using their SEO skills to drive a modified version of the now defunct software, delivered from the bad guy’s site, to the top of Google’s rankings resulting in the malware quickly spreading. When downloaded the malware does nothing to the computer, but attempts to convince the victim to buy the “full” version of the software for $29.95 (£23).
The threat actors do such a good job of SEO that the modified version of Movie Maker also placed first on Bing, which has the second largest global market share and on the first page of other search engines, ESET researchers said in a 9 November blog post.
At the time of ESET publishing its blog post, the website spreading the modified software, ‘windows-movie-maker.org’, comes up as one of the top results when searching for “Movie Maker” and “Windows Movie Maker” on Google (using this browser, it ranks as number one in the majority of countries with the highest number of internet users). On Bing, the search engine with the second largest global market share, the website is also placed on the first page of results.
ESET security products detect the scam as Win32/Hoax.MovieMaker and block the website distributing it. We have notified both Google and Microsoft about the fraudulent nature of the high-ranking website (which was registered back in 2010).

As a consequence of the website’s high search engine ranking, the crooks behind the scam have managed to reach a global “audience”, with the modified Windows Movie Maker emerging among the most prevalent threats in ESET’s telemetry in the past few days.
On November 5, 2017, Win32/Hoax.MovieMaker was the third most detected threat worldwide and the number one threat in Israel. As of November 6, our telemetry recorded many detections in the Philippines, in Israel, Finland and Denmark.

How the Windows Movie Maker Scam works
When users install the software offered on the above-mentioned website, they get a functioning Windows Movie Maker. However, unlike the official and free Windows Movie Maker by Microsoft, this one claims to be a trial version that needs to be upgraded to a full version in order to offer all features.
The user is repeatedly prompted to purchase the full version, first when the software is launched and later when the user tries to save a new document. In the latter case, the prompt prevents the user from continuing, making it appear as if saving a document was a paid feature.

The price requested for the fake upgrade is set to $29,95, in what is presented as a 25% discount on the payment website used by the crooks.

How to stay safe from Windows Movie Maker Scam
If you’ve already installed the Movie Maker offered on windows-movie-maker.org, uninstall it and run a scan using a reputable antimalware solution.
To avoid falling victim to similar scams, always stick to official sources when downloading software. If you really need to use a piece of software that’s no longer distributed by its original maker, make sure you:
- Use a reliable security solution to detect and block malicious content.
- Consider using the official replacement for the discontinued software – in this case, Windows Story Remix.
- Don’t pay for software that is or was officially offered for free. Information on software pricing should be available online.
