Whatodo Browser Hijacker
Our team conducted an evaluation of the Whatodo browser extension and determined that it operates as a browser hijacker. Its primary objective is to promote gsrcunow.com, a fraudulent search engine, by modifying the settings of the compromised browser. Typically, users unknowingly introduce browser hijackers into their browsers.
The Whatodo browser extension makes several alterations to the settings of the targeted browser. These changes encompass modifying the default search engine, homepage, and new tab page settings, ensuring that users are directed to gsrcunow.com. However, it's crucial to exercise caution because this counterfeit search engine ultimately redirects users to bing.com, a search engine operated by Microsoft, in an attempt to appear legitimate.
The utilization of deceptive search engines like gsrcunow.com carries numerous risks. These search engines are often designed to monitor user activities, collect personal information, and present customized advertisements. Moreover, fraudulent search engines may incorporate questionable ads and links that promote potentially harmful websites within their search results.
Eliminating counterfeit search engines can be a challenging task, as they may resist efforts to revert browser settings to their original state. Users may require specialized tools or detailed instructions to successfully remove them.
How Are Browser Hijackers Commonly Distributed?
Browser hijackers are commonly distributed through various methods, and cybercriminals often employ deceptive tactics to trick users into unwittingly installing them. Here are some of the most common distribution methods for browser hijackers:
Software Bundling: This is the most prevalent method for distributing browser hijackers. Cybercriminals bundle the hijacker software with legitimate free applications or downloads from the internet. When users download and install these free programs, they often overlook or miss the bundled browser hijacker, leading to unintentional installation.
Deceptive Websites: Some websites, often of dubious nature or containing pirated content, may prompt users to install a browser extension or add-on as a prerequisite to access certain content or features. In reality, these extensions are browser hijackers.
Malicious Email Attachments and Links: Browser hijackers can also be distributed through malicious email attachments or links in phishing emails. Clicking on these links or downloading the attachments can trigger the installation of the hijacker.
Fake Software Updates: Cybercriminals may create fake software update notifications that mimic legitimate updates for browsers or other software. Users who click on these fake update prompts may unknowingly install browser hijackers.
Clickjacking: In some cases, malicious websites use clickjacking techniques to trick users into clicking on hidden buttons or links that trigger the download and installation of browser hijackers.
Social Engineering: Cybercriminals may employ social engineering tactics to manipulate users into installing browser hijackers. For example, they might use pop-up messages or fake security alerts that claim the user's system is infected and prompt them to install a supposed security tool that is, in fact, a browser hijacker.
Freeware and Shareware Sites: Users who frequently download software from freeware or shareware websites may encounter browser hijackers packaged with seemingly legitimate applications. These third-party download sources may not adequately vet the software they host.
Browser Vulnerabilities: In some cases, browser hijackers can exploit vulnerabilities in a user's web browser to gain unauthorized access and make changes to the browser settings.
