Learn how to fix the Rackcdn virus Mac problem, where the web browser is repeatedly forwarded to a fake threat alert page pushing a rogue system utility.
A web browser is the most heavily exploited area in Mac malware distribution campaigns. That’s probably because this environment is the lowest-hanging fruit compared to the rest of the operating system’s components, which is on the plus side of Apple’s platform security in general but still a cold comfort for those who fall victim to such attacks. The users experience a harsh tampering with their web surfing activity, typically manifested as browser redirects accompanied by irritating popups. One of the long-running waves of such malicious code propagation involves the rackcdn.com domain, which is part of a content delivery network provided by American cloud services company Rackspace. By “weaponizing” the reputable online infrastructure, the malefactors make sure that their fraud campaign isn’t interrupted as part of commonplace browser security practices.
The raid stems from an infiltration of a harmful browser plugin into the Mac. This is usually a matter of bundling, a software promotion method originally designed to be benign but also notorious for being a source of malware trespassing on computers. The crooks cook up complex setup clients that install potentially unwanted applications (PUAs) alongside inoffensive ones. Therefore, when getting themselves some new free and useful program Mac users should pay close attention to the items that hide underneath the default install. Thankfully, it’s easy to do – just peek into the custom options and take a look at the items listed there. If there is one that seems suspicious, but sure to uncheck it right away. Zooming back in, the attack commences with a wrongdoing element being added to one’s browser, which instantly modifies a number settings and starts redirecting Safari, Chrome, or Firefox to rackcdn.com domain without the victim’s consent.
In the resulting URL string, the rackcdn.com part will be prepended with numerous hexadecimal characters and a fragment like “r5.cf1” while being concatenated with many more gibberish characters. So, the address bar will be in the following format: [random].r5.cf1.rackcdn.com/[random]. Note that the number in the prefix may vary. The redirect activity will be going off in a haphazard way and accompany some standard actions of the user, such as opening the browser, running a web search or triggering a new tab. When on the landing page, the victim will see a warning allegedly from AppleCare Protection Plan that says, “Your system is infected with 3 viruses!” The spoof site also provides details about the pseudo predicament, emphasizing that the current system damage is 28.1% due to the misdemeanor of 2 malware and 1 phishing/spyware samples.
Furthermore, there will likely be a popup alert going, “Immediate action required. The last website you visited has infected your computer with a Trojan.U83. Immediate repair is required. Click Ok to continue”. The footnote about the Mac’s exposure to being “permanently damaged” if the victim leaves the page is supposed to add more pressure to the brainwashing. Ultimately, by opting into what the rackcdn.com scam wants, the user runs the risk of downloading and installing a Mac scareware application, such as Mac Cleanup Pro. This secondary payload will only make matters worse as it will display noxious scans reporting imaginary system performance issues and inexistent threats in order to fool the victim into buying the full version in exchange for the fix. It goes without saying that users shouldn’t fall for this scam. Instead, it’s strongly recommended to remove rackcdn virus from Mac.
