What Is BrightStart Mac Virus?

remove brightstart mac virus


BrightStart is a malicious browser add-on that infiltrates MacOS browsers and displays unwanted pop-ups. BrightStart does not carry any malicious code which would give it access to your private information or data and it does not spy on you, but the browser redirect may be frustrating for some users. Students who use Mac computers in university have been affected by this malware. The Firefox and Chrome extensions also turned out to be malicious and have been removed by the respective companies, but BrightStart remains. At the time when this incident was discovered, the BrightStart software still existed in the MacOS app store. BrightStart is associated with one of the EU’s Dirty Dozen list and is classified by as a Potentially Unwanted Application. The potential issue is that MacOS requires users to agree to Terms & Conditions before installing an application, as part of Apple Developer Program membership.

How Is BrightStart Mac Virus Distributed?

The MacOS version of BrightStart infects a Mac computer in different ways:

  1. By popping up a warning message when the user tries to install or update an application.
  2. 2. From an attachment in an email (emails from unknown sources are not allowed in the Mac mail client by default).
  3. 3. Through a link in an advertisement or text message, which is sent from an ad server.
  4. This malware is often distributed through email messages. For example, a student installs the BrightStart browser extension for a university computer, but then receives spam emails with attachments or links that install it. The spam messages are usually disguised as an advertisement or as an invitation to join a waiting list. As BrightStart is a browser extension that affects Mac computers, it does not show up in the list of installed programs.
  5. When the attack is carried out in this way, BrightStart does not have any legitimate purpose to offer users.

Due to their appearance, links or ads from unknown sources are often perceived as suspicious and therefore users should not click on them.
