A new scam wave is underway that dupes computer users into applying a rogue Critical Chrome Update, which ends up installing malicious software instead.
The present-day social engineering techniques aren’t restricted to things like dumpster diving, tailgating, spear phishing or cold-calling. In fact, browser hijacking does the trick quite well for the online realm. This method is also a godsend for crooks who try to deposit harmful code on PCs. A recent campaign involving Critical Chrome Update popups is aimed at manipulating gullible users into clicking a booby-trapped Download Now button. The actual payload tends to be a self-extracting ZIP archive with spyware or file-encrypting ransomware on board.
Some of the reported domains hosting these malicious executables include tahxiintimes-niedersachsen.org, johphblogger-hints-and-tips.org, and iexaidlepro.org. The network of these unsafe pages is fast-flux, so the domain names keep changing so that blacklisting mechanisms or web browsers and antimalware suites do not block them. The actual URL will also contain a long tail of random-looking characters so that the right infection is delivered.
The threat actors at the helm of this fraud have made their landing page look true-to-life. The design encompasses a large logo in the center that’s identical to Chrome’s. The part above it includes the inscription “Critical Chrome Update” and the above-mentioned download button leading to a site that hosts the actual malware. The deceptive website under scrutiny pops up for a reason. These recurrent events indicate the presence of a potentially unwanted program (PUP) on the machine. In other words, the issue is isolated to a specific computer. Web browsers start acting up because the perpetrating plugin forces the Internet preferences to default to a wrong value.
Consequently, the splash screens or new tabs with the fake Critical Chrome Update message will be appearing in the middle of the victim’s web surfing sessions. Incidentally, other browsers such as Firefox, IE and Safari, may be at risk as well. Not only do such interruptions diminish user experience, but they also call forth browser instability and privacy issues. The latter side effect may be due to the harvesting of personally identifiable data related to one’s Internet navigation.
The PUP in question usually slithers its way into a system by dint of a tricky method called bundling. The downloader for this redirect virus smolders inside third-party software installation clients. The affiliated programs are mainly innocuous freeware entities that look like a lure, so most people just keep hitting Next to complete the setup quickly. But the peril hides within the recommended installation option, so it will sneak inside without letting the would-be victim know. The moral of the story is that it’s imperative to at least have a look at the custom setup configuration, which should display the complete list of promoted software. In case the Critical Chrome Update scam popups are constantly going off during web browsing, be sure to use the malware removal walkthrough below.
