Since Chrome will never interrupt your browsing experience to prompt you to update by default, it’s clear that you’re dealing with a PUP or browser hijacker if you get this message while browsing the Internet using Google Chrome.
Keep in mind that this malware is different from the Urgent Chrome Update Pop-up Scam and needs to be removed in a different way.
How the Critical Chrome Update Scam works
The Critical Chrome Update scam is one of the newest social engineering techniques created to deliver harmful code to an unsuspected user. The end goal is to convince the user to click the Download Now button. This will trigger the download of a self-extracting BAT file that most likely contains a web browser toolbar, an “optimization utility” or another type of product that will end up generating pay-per-click revenue to the adware publisher. However, there is a more serious possibility where the Download Now button will trigger the download of spyware of file-encrypting ransomware. Security reports on this particular malware scam have reported the following domains as hosts:
iexaidlepro.orgjohphblogger-hints-and-tips.orgtahxiintimes-niedersachsen.org
Note: These are just the most popular occurrences. Since the network of these pages is fast-flux, the domain names keep changing in an attempt to avoid blackmailing mechanisms and antimalware suites. Furthermore, the actual URL will contain a long tail of random-looking characters. Design-wise, the landing page with the large logo and the genuine-looking Download Now button is identical to Chrome’s Download Page. The scam is definitely an improvement to the rudimentary Chrome Update Pop Up Scam.
The scam is powered by a PUP
The apparition of this scam tab is not scripted by any action that the user has to take. The malware page is programmed to appear in the middle of the user’s browsing session in order to make it look genuine. A PUP is a type of malicious software capable of infecting a computer without the permission of the user. In this particular case, the PUP that is causing this malicious behavior most likely arrived by an extremely popular method called bundling. Bundling is the act of hiding malicious code or redirect in a third-party installation client. Since most 3rd party programs used are freeware available on popular download sites, users will usually just hit the Next button without unchecking the installation of bundled software. Once the PUP arrives safely on the victim’s computer, it will start hijacking the Chrome browser in order to create redirects that will steer the user towards clicking the Download Now button that will download the actual virus.
