Google Chrome “Font wasn’t found” Malware Scam” – that’s cool, I don’t need that font anyway.

Categories: Computer, Malware, and Online Protection.

 

Recently a Google Chrome scam has been observed that can infect a computer with crafty malware.

This scam called “Font wasn’t found” involves malware that changes website text into missing objects in order to appear as if the font is missing from the website.This fake font update is hosted on compromised websites that contain outdated security patches or plugins. Upon visiting a compromised site, a “HoeflerText font wasn’t found” popup message appears intending to trick the user into downloading a font file, disguised as a browser update. Compromised websites are hotspots for hosting malware that waits for unsuspecting website visitors to download and execute, a.k.a. Drive by downloads.

So, What does the scam do?

Once downloaded, the malicious file injects and rewrites a portion of the script within an unsecure website (due to outdated security patches) to generate the fake update which is used to trick the user into installing the file. Once the malware is installed, it is capable of collecting personal data from the PC and browser information such as website visitations.

How can I identify this scam?

  1. The text within the dialog window displays a running version of Chrome 53, which you shouldn’t have because you are updating your browser, right? So, the indication that this message has a lower browser version would be one key indicator.

  1. The file names are also suspicious and inconsistent. Upon clicking the “update” button the executable file (.exe) is listed as “Chrome Font v7.5.1.exe” This file is not labelled as “Chrome_Font.exe” like in the in malicious instructions.

And 3 – Another indicator would be a prompt from google warning you that “This file isn’t downloaded often” as you try to download the file.
