Examination of the Currency Helper application has revealed that it functions as a browser extension with the primary intention of taking over relevant browser settings.

Browser Hijackers Like the Currency Helper may Cause Privacy Issues

The Currency Helper manipulates the default search engine, homepage, and new tab page settings of users' Web browsers, forcing them to use the fraudulent search engine for their online searches. Upon evaluating, it is apparent that it doesn't provide results on its own. Instead, it shows users' results taken from Bing, a reputable and widely recognized search engine.

It is of utmost importance to acknowledge the potential hazards associated with using unreliable search engines. These questionable search engines often promote schemes, dubious websites, intrusive PUPs (Potentially Unwanted Programs) and other similar risks. Engaging with such search engines poses a significant threat to online security, and it is strongly advised to refrain from utilizing them in order to protect oneself from these potential risks.

Furthermore, the Currency Helper is likely to have the capability to gather various types of data. The information collected by such dubious PUPs could be utilized for marketing purposes, sold to third parties, or exploited in other ways that could compromise online privacy and security. It is essential for users to exercise caution and be mindful of the potential consequences when using applications that have access to personal data.

PUPs and Browser Hijackers Often Mask Their Installation

The distribution of PUPs and browser hijackers often involves a variety of shady tactics that exploit unsuspecting users and their browsing habits. These tactics are designed to trick or coerce users into unknowingly installing unwanted software or allowing unauthorized changes to their Web browser settings.

One common method employed is bundling, where PUPs and browser hijackers are packaged together with legitimate software downloads. In this scenario, users may inadvertently install unwanted programs alongside the desired software without realizing it. The bundled installers often hide the presence of the additional software through deceptive installation prompts or by burying the disclosure deep within lengthy terms and conditions.

Another tactic involves misleading advertisements and pop-ups that mimic system alerts or notifications. These deceptive advertisements attempt to create a sense of urgency or fear, enticing users to click on them. Once clicked, users may be redirected to websites that automatically initiate the download or installation of PUPs or browser hijackers without their consent.

Social engineering techniques also are frequently employed. This involves manipulating users through psychological tactics, such as exploiting their curiosity, trust, or lack of technical knowledge. Attackers may utilize deceptive messages or notifications that mimic legitimate software updates, anti-malware scans or security alerts. By presenting these messages convincingly, users may be tricked into clicking on links or downloading files that contain PUPs or browser hijackers.

Moreover, certain PUPs and browser hijackers masquerade as helpful tools or enhancements, promising to improve user experiences or provide exclusive features. These deceptive programs may present themselves as legitimate browser extensions, system optimization tools, or media players. Users may willingly install them, unaware of their true nature and the intrusive changes they will introduce to their systems or browsers.
