What is rackcdn[.]com?

rackcdn[.]com is a legitimate website, the domain of which is owned by a company called Rackspace. This page is a part of Rackspace CDN (Content Delivery Network) and is not malicious. The main goal of the CDN service is to provide fast content delivery for visitors to their web pages, however, some criminals exploit CDN services to deploy deceptive, untrustworthy content (dubious ads, redirects to potentially malicious websites, and so on).

rackcdn.com scam

As mentioned, rackcdn[.]com is trustworthy, however, visitors are redirected to other pages that are not. This is a result of exploits caused by scammers and malware developers. Visitors are forced to visit scam websites, for example ssl.cf6.rackcdn.com. Once opened, these pages display fake virus alerts, notifications about errors, and so on. Scammers use these pages to trick people into believing that their computers/operating systems are infected or damaged, and then encourage them to download potentially unwanted applications (PUAs). These scam websites, and apps promoted through them, should not be trusted. Some of these websites are used to trick visitors into contacting scammers, who disguise themselves as tech-support workers. Once contacted, the scammers urge people to purchase software, use paid services, and so on. In summary, these rogue pages are used to extort money from unsuspecting users. Additionally, criminals can use rackcdn[.]com to promote malicious programs. Thus, having them installed can lead to computer infections, which in turn might lead to even more serious problems such as financial/data loss, and so on. This page can also be used to cause redirects to pages full of advertisements (coupons, banners, surveys, etc.) that, if clicked, might open malicious pages or cause installation of PUAs. We recommend that you avoid using rackcdn[.]com and do not trust scam sites and other dubious pages (and apps promoted on them) that could be opened through the website.

Many web pages may seem harmless, however, visiting them often causes unwanted results. A number examples of other websites that lead to rogue pages and display dubious ads are savefrom[.]net and youtubnow[.]com. To avoid unwanted download/installation of unwanted applications, do not visit this or any other similar websites.

How did potentially unwanted applications install on my computer?

In most cases, unwanted apps infiltrate systems without direct users' permission. They are installed when software developers use a deceptive marketing method called "bundling" or through intrusive advertisements that, if clicked, cause unwanted downloads and installations. Bundling is used by developers to trick people into installing potentially unwanted applications together with regular, usually free software. They hide bundled apps in "Custom", "Advanced" and other options/settings of software (download/installation) set-ups. Furthermore, many people download and install software without checking the settings. In doing so, they cause unwanted download and installation of additional, unwanted apps.

How to avoid installation of potentially unwanted applications?

Download software from official and trustworthy sources (web pages) and using direct links only. Do not use third party downloaders/installers, torrents, eMule or other Peer-to-peer networks, dubious/unofficial pages, and so on. Install downloaded software correctly. Check "Custom", "Advanced" and other similar settings of any setup and deselect offers of unwanted apps. Intrusive ads cannot be trusted. If clicked, they cause unwanted downloads/installations or redirects to untrustworthy websites such as adult dating, gambling, pornography, and so on. If you encounter these redirects regularly, or ads are displayed on any visited website, check your web browser for any unwanted/suspicious applications (extensions, plug-ins, add-ons). Remove all unwanted or suspicious apps immediately. Also, check the list of installed programs on your computer and uninstall unwanted, dubious software. If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate them.
