Adrozek malware infects browsers

The Microsoft 365 Defender Research Team reports on a new type of malware. Known as Adrozek, this malware infects a PC, then modifies your browser of choice to inject sketchy ads into search results pages.

If not detected and blocked, Adrozek adds browser extensions, modifies a specific DLL per target browser, and changes browser settings to insert additional, unauthorized ads into web pages, on top of the legitimate ads from search engines.

The hackers earn money through affiliate advertising programs, which pay them by the amount of traffic referred to the sponsored affiliated pages.
