Removing Overbright adware-type application and the ads it delivers

Also Known As: Ads by Overbright
Type: Mac Virus
Damage level: Medium

What kind of application is Overbright?

Our research team found the Overbright application while investigating submissions to the VirusTotal platform. After examining this app, we determined that it is advertising-supported software (adware). It is pertinent to mention that Overbright belongs to the Pirrit adware family.

Overbright adware overview

Adware is designed to generate revenue for its developers by feeding users with unwanted and deceptive ads. This third-party graphical content (e.g., pop-ups, overlays, banners, surveys, etc.) is displayed on visited websites and/or other interfaces.

Software within this classification might require certain conditions to run intrusive advertisement campaigns (e.g., compatible browser/system specs, visits to particular sites, etc.). Yet even if adware (e.g., Overbright) does not display adverts – it endangers device integrity and user safety.

Adware-delivered advertisements predominantly endorse online scams, unreliable/dangerous software, and potential malware. Some intrusive ads can be triggered (i.e., by being clicked) to execute scripts that perform stealthy downloads/installations.

Keep in mind that while genuine products/services may be encountered through these adverts – they are highly unlikely to be promoted in this fashion by any official parties. It is most probable that this endorsement is undertaken by scammers who abuse the content's affiliate programs in order to obtain illegitimate commissions.

We have previously detected adware-type apps from the Pirrit family with browser-hijacking capabilities – however, Overbright did not exhibit these traits during our analysis.

Advertising-supported software typically has data-tracking functionalities, and this might apply to Overbright. Information of interest may include: URLs visited, webpages viewed, search queries typed, Internet cookies, log-in credentials (usernames/passwords), personally identifiable details, credit card numbers, etc. The collected information can be monetized via sale to third-parties.

In summary, the presence of software like Overbright on devices can lead to system infections, severe privacy issues, financial losses, and even identity theft.

Adware examples

We have examined countless adware-type applications; RavenwiseAtechny, and Pipidae are merely a couple examples of our newest finds.

Adware usually appears legitimate and promises a broad range of "handy" features. However, these functionalities are typically fake and nonoperational – their purpose is to serve as bait that lures users into downloading/installing the software.

It must be stressed that even if an app or a browser extension operates as indicated by its promotional material – that is not irrefutable proof of either legitimacy or safety.

How did Overbright install on my computer?

Adware can have "official" download pages, and it was promoted on scam websites. Uses mainly enter these webpages via redirects generated by misspelled URLs, sites employing rogue advertising networks, spam browser notifications, intrusive ads, or installed adware (with browser force-opening abilities).

"Bundling" – packing ordinary program installation setups with unwanted/malicious additions – is also used in adware distribution.

The danger of inadvertently allowing bundled content into the device is increased by downloading from dubious sources (e.g., freeware and third-party websites, Peer-to-Peer sharing networks, etc.) and by treating installation processes with negligence (e.g., skipped steps, using "Easy/Express" settings, etc.).

Intrusive adverts proliferate advertising-supported software as well. When clicked on, some of these advertisements can execute scripts to perform downloads/installations without user permission.

How to avoid installation of adware?

We recommend researching software and downloading it only from official/trustworthy channels. Installation processes must be treated with care, e.g., by reading terms, studying available options, using the "Custom" or "Advanced" settings, and opting out of all additional apps, extensions, tools, etc.

Due to the legitimate and harmless appearance of fraudulent and malicious online content – we also advise exercising caution while browsing. For example, while intrusive ads may look innocuous – they redirect to unreliable and questionable sites (e.g., gambling, adult dating, pornography, etc.).

If you keep encountering such advertisements and/or redirects, check the device and immediately remove all suspect applications and browser extensions/plug-ins. If your computer is already infected with Overbright, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate this adware.
