'Google Chrome Fatal Error!' Pop-Ups
The 'Google Chrome Fatal Error!' pop-up windows, as well as their versions for Mozilla Firefox and Internet Explorer, are generated on websites like securityfalse[.]ga. These websites are used to promote access to uncertified computer support services and convince users to download and run corrupted files. Reports from platforms like Malware-traffic-analysis.net and various AV companies suggest that the group dubbed 'ElTest' is running a massive campaign on the Internet that involves the usage of fake 'Google Chrome Fatal Error!' security warnings and 'The "HoeflerText" font wasn't found' notifications. The ElTest campaign is reported to disperse threats like the CryptoShield 2.0 Ransomware and the Mole03 Ransomware by luring users to download a file named 'Font_Chrome.exe,' which is supposed to include the "HoeflerText font." The 'Google Chrome Fatal Error!' pop-up messages designed by ElTest are known to be delivered via scripts on compromised pages and suggest users that they are infected with the Zeus Banking Trojan and RDN/YahLover.worm!055BCCAC9FEC. The group is known to use tools like the RIG Exploit Kit and the Angler Exploit Kit to present users with misleading content.

The ElTest malware distribution campaign is quite extensive, and it employs dozens of IP addresses to circumvent Web filters and security shields. Browsers like Google Chrome and Mozilla Firefox have joined efforts with AV companies to block access to known infection sources.

Computer security researchers recommend users incorporate multiple protection mechanisms that complement each other and make for a solid cyber defense. We have seen the ElTest campaign take advantage of the 126.96.36.199 and the 188.8.131.52 IP addresses. As mentioned above, there are possibly hundreds of IP addresses that are being in active use to distribute phishing pages and expose users to threats.
