A newly discovered DNS-changer Trojan dubbed Extenbro has been observed while blocking access to websites of security software vendors to prevent its victims from getting rid of the adware it dumps on their computers. Malwarebytes Labs’ researchers say the new malware will also expose the machines it manages to compromise to all sorts of other threats. The malware will infect its targets after they download an adware bundler, a software bundle usually served together with adware or spyware components which get downloaded on the victim’s computer with the help of a downloader module.
