Google Chrome, Mozilla Firefox, Microsoft Edge, and other browsers are suffering from an ongoing malware campaign. The attack has affected multiple browsers and is designed to inject ads into search results and add malicious browser extensions as well.

According Gadgets360 Report a Microsoft The blog post stated that from May to September 2020, the company recorded hundreds of thousands of encounters of the Adrozek malware around the world. The tech giant even crawled 159 unique domains, each of which housed an average of 17,300 unique URLs. This, in turn, housed an average of more than 15,300 different polymorphic malware samples. The main objective of the malware is to lead users to affiliate websites and even show them ads by injecting them into search results.

Furthermore, the malware achieves this by silently adding other malicious browser extensions as well. This changes your browser settings to insert ads on web pages, where you would not otherwise find them. These ads can be found in addition to other legitimate search engine ads and are claimed to also modify DLLs by target browser. In simpler terms, you can disable security controls in the browser.

According to a Microsoft researcher, “Despite targeting different extensions in each browser, the malware adds the same malicious scripts to these extensions. In the past, browser modifiers calculated hashes like browsers do and update safe preferences accordingly. Adrozek goes one step further and patches the function that starts the integrity check. “
