MacBright – How Did I Get It

Software bundling is most likely the primary technique that distributes MacBright adware. With the help of this technique adware’s owners are able to bundle their deceptive program with various free third-party apps. In order to trick you into installing on your Mac they conceal the information about its presence hoping that you will choose to follow the basic installation steps. Actually one way to prevent the installation of PUPs like MacBright is to select the Advanced/Custom configuration steps during the installation process of new apps. Usually, they are set to present information about existing extras as well as option to opt out their installation.

Another spread technique that may grant MacBright adware access to your device is called drive-by download. It occurs after you visit compromised web pages that are set to exploit existing browser vulnerabilities. So in case that the malicious code injected in the source code of such pages detects a flaw it could exploit, it becomes able to drop and activate the code of the adware directly on the device.

MacBright – More Information

MacBright adware is a program that once started on a target system aims to access and modifies predefined browser settings of target web browsers. All changes could happen without your knowledge which is one of the reasons why this program is categorized as a potentially unwanted one.

The purpose of all changes implemented by MacBright is the generation of many annoying ads during browsing sessions. All ads that could appear on each website you visit could attempt to trick you into visiting the bogus websites they promote. Some of them could be recognized by the phrases:

  • Ads by MacBright
  • Promoted by MacBright
  • Ads generated by MacBright
  • Promotions by MacBright

Beware that the offers on these websites may be misleading and eventually scam you to provide sensitive credentials. So for the sake of your security and the security of your device you should avoid entering any sensitive credentials or downloading presented apps.

Unfortunately, there is a potential risk that some of the ads generated by MacBright could be set to land users on web pages corrupted by hackers. An eventual visit of such page could result in serious issues related to the security of your Mac.

Another purpose that MacBright adware could have is data collection. And this could be explained by the fact that its owners need certain details about you and your browsing behavior for the improvement of their advertising campaigns. So as long as the program is running on the system it may be able to obtain details like:

  • Visited URLs and websites
  • Browser’s home page
  • Search queries
  • Search queries on the visited web pages
  • Type of used browser
  • Operating system type
  • Internet protocol (IP) address
  • Geographic location
  • The domain name of current Internet service provider (ISP)

In case that you don’t agree with all nasty practices associated with this program you should remove it from your Mac as soon as possible. You can try to do this by following the detailed removal guide that follows.
