It works as an advertising platform and may be used for promoting expensive items, useless services, or even malware.[1]

However, unexpected S3.amazonaws.com pop-ups should not be ignored. Original Amazon aws S3 or Amazon Web Service (AWS)[2] is not malicious. It’s a legitimate cloud storage web service that belongs to Amazon Inc.

Many people prefer using this service due to the multiplicity of functions and fair pricing. Nonetheless, cybersecurity experts warn that cybercriminals might misuse the S3.amazonaws services for malicious activities, such as scam or malware dissemination.

S3.amazonaws.com scam pop-ups state:

According to people who encountered this problem, they started seeing https://s3.amazonaws.com/addns/CH3088/CvCHff.html as a default new tab URL on Google Chrome and Mozilla Firefox. Mac users also encounter these pop-ups on their Safari browsers, so there is no exclusion to a particular OS.

In some of the cases, this doubtful URL is replaced by www.adfactorytech.com/resources/Re/Chnh/mov.php domain, which redirects to third-party search domains. In addition to that, people may also see the following status at the top-left corner of the web browser’s window when trying to access any website:

  • Waiting for S3.amazonaws.com

PUPs can be distributed via software packages

Cybersecurity experts warn people that PUPs like adware and browser hijackers can be distributed via software bundling. Freeware developers agree to attach free add-ons, toolbars, plug-ins, and extensions for monetization purposes.

The problem is not such a distribution method, technically known as bundling, but the way freeware developers disclose them. Usually, additional installers are hidden under Quick or Basic installation methods. If the user selects this method, he or she unintentionally agree to install all of them. As a consequence, the web browser may be hijacked and start initiating various unwanted activities.

According to NoVirus.co[5] team, the only way to prevent malware from installing onto your PC, you have to install free programs this way:

  • Select freeware download source carefully;
  • Then opt for Advanced or Custom installation method;
  • Read License Terms;
  • Remove checkmarks from additional components;
  • Then finish the installation and check if the freeware did not drop malware. You can do that by opening Control Panel, sorting programs by date and look for unknown programs installed recently.

Additionally, you should avoid browsing on suspicious websites. Hackers can inject malicious codes into websites and misuse them for malware distribution.
