ValidBoost

ValidBoost is identified as a Potentially Unwanted Program (PUP) with dual functionality, acting as both adware and a browser hijacker designed explicitly for Mac devices. Referred to interchangeably as ValidBoost and ValidBoostfld, this application exhibits intrusive behavior by displaying advertisements and manipulating browser settings to promote a fake search engine.

The primary objective of ValidBoost is to generate revenue through advertising while redirecting users to a deceptive search engine. This redirection occurs as a result of alterations to the browser settings initiated by the application. Additionally, there are concerns about the potential collection of user information by ValidBoost. The distribution method employed by ValidBoost involves a deceptive installer masquerading as an Adobe Flash Player installer.

ValidBoost Could Harvest Sensitive User Data Once Installed

Typically, adware operates by generating revenue for developers through the delivery of various forms of advertisements such as banners, pop-ups, coupons, surveys, and the like. In the case of applications like ValidBoost, the advertisements often serve to promote dubious websites. Clicking on these advertisements can lead to unintended downloads or installations, particularly if the advertisements are designed to execute specific scripts. It is advisable to exercise caution and ignore advertisements originating from applications like ValidBoost.

Another noteworthy issue with the ValidBoost application is its capability to alter browser settings in favor of a fake search engine. Specifically, ValidBoost designates the address of a fake search engine as the browser's default search engine, homepage and new tab pages. When a user's browser is hijacked by ValidBoost, they are compelled to visit a specific address each time a new tab page is opened or a search query is initiated via the URL bar. This manipulation can result in search results containing links to potentially harmful sites, questionable ads, or redirection to untrustworthy addresses.

Furthermore, adware, browser hijackers, and other PUPs often engage in the collection of browsing data and other information. Commonly targeted browsing-related details include IP addresses, visited page URLs, entered search queries and geolocations. It is worth noting that specific intrusive rogue applications may go beyond this and access sensitive, private information, such as credit card details and passwords.

The collected information may serve various purposes, including marketing efforts, being sold to third parties, or even being utilized for unsafe activities like identity theft, unauthorized transactions, and unauthorized purchases. Therefore, users are strongly advised to remain vigilant and cautious when dealing with adware and similar applications to safeguard their privacy and security.

PUPs Often Sneak Their Installations Through Deceptive Distribution Practices

PUPs often employ deceptive distribution practices to install themselves on users' systems without clear consent sneakily. Here are some common tactics used by PUPs:

• Bundled Software: PUPs are frequently bundled with legitimate software downloads. Users might unknowingly install the PUP alongside the desired software if they don't carefully read the installation prompts. This bundling is often mentioned in the fine print, and users may inadvertently agree to the installation by rushing through the process.
•  Fake Updates and Installers: PUPs can disguise themselves as software updates or installers for popular programs. Users, thinking they are updating or installing a legitimate application, may unknowingly download and install the PUP instead. This is a common tactic used by malicious actors to exploit users' trust in software updates.
•  Misleading Advertisements and Pop-ups: PUPs often use misleading advertisements and pop-ups to trick users into clicking on them. These advertisements may claim to offer system optimizations, security scans or other enticing services. Clicking on these advertisements may lead to the unintentional download and installation of the PUP.
•  Social Engineering Tactics: PUPs may employ social engineering techniques, such as fake warnings about malware infections or system errors, to manipulate users into downloading and installing the program. Fearful of potential threats, users may be more likely to follow the suggested actions without verifying the legitimacy of the source.
•  Freeware and Shareware Platforms: PUPs may be distributed through freeware and shareware platforms. Users downloading free software might be unaware that the software comes bundled with additional, unwanted programs. The PUPs are often included in the terms of service, which users may not thoroughly review.
•  Email Attachments and Links: Some PUPs are distributed via email attachments or links. Users may receive seemingly legitimate emails with attachments or links, and upon opening or clicking, the PUP is downloaded and installed on the system. This tactic is often used in phishing campaigns.
•  Browser Extensions: PUPs can be distributed as seemingly innocuous browser extensions. Users might install these extensions to enhance their browsing experience, but in reality, the extensions may carry out unwanted activities, such as displaying intrusive ads or collecting browsing data.

To avoid falling victim to PUP installations, users should practice caution when downloading software, carefully read installation prompts, keep software updated through official channels, use reliable security software, and remain skeptical of unexpected pop-ups or emails prompting them to download or install anything.
