Malware campaign adding extensions in Chrome, Firefox: Microsoft
Google Chrome, Firefox, Microsoft Edge, and Yandex browsers are affected by an ongoing malware campaign that is designed to inject ads into search results and add malicious browser extensions, Microsoft revealed on Thursday. Dubbed Adrozek, the newly discovered malware family has been at scale since at least May this year and the attacks peaked in August with the threat being noticed on more than 30,000 devices every day.
Microsoft said that from May to September, it recorded hundreds of thousands of encounters of the Adrozek malware globally. The company tracked 159 unique domains, each hosting an average of 17,300 unique URLs, which, in turn, host an average of over 15,300 distinct, polymorphic malware samples.
