An ongoing malware campaign is blasting the Internet with malware that neuters the security of Web browsers, adds malicious browser extensions, and makes other changes to users’ computers, Microsoft said on Thursday.

Adrozek, as the software maker has dubbed the malware family, relies on a sprawling distribution network comprising 159 unique domains with each one hosting an average of 17,300 unique URLs. The URLs, in turn, host an average of 15,300 unique malware samples. The campaign began no later than May and hit a peak in August, when the malware was observed on 30,000 devices per day.
