Adware

Video Downloader is a browser extension that, while promising to allow users to easily download videos from the internet, also displays advertisements in the browser and can lead to various security issues. This extension is classified as adware, a type of malicious software that delivers unwanted advertisements to users. Once installed, the Video Downloader extension begins to display advertisements in the browser, often in places where they shouldn't be. It can also redirect website links to different sites than expected and manipulate browser search queries to go through unwanted search engines. More alarmingly, the Video Downloader extension can spy on users' browsing activity, collecting data such as browsing and search engine histories, personally identifiable details, usernames/passwords, credit card numbers, and other sensitive information. This collected data can then be sold to third parties, potentially leading to severe privacy issues, financial losses, and identity theft. The Video Downloader extension primarily targets web browsers, with Google Chrome being a common target. However, it's not limited to Chrome; it can also affect other browsers that support similar extension frameworks, such as Microsoft Edge.

PureLand Stealer is a type of malware that specifically targets Mac devices. It falls under the category of "stealer" malware, which are programs designed to extract sensitive information from infected systems. PureLand primarily targets cryptocurrency wallets and other sensitive data, posing a significant threat to the integrity of the infected device and the user's privacy. Once PureLand successfully infiltrates a system, it may display a prompt requesting the victim to provide the password for "Chrome Safe Storage".

Adware is a type of software that displays unwanted advertisements, often in the form of pop-ups, on a user's device.
