It is the subtle manipulation of these IT services that advanced hacking campaigns often exploit in the real world.

BitDefender caught a campaign of attackers hijacking the DNS settings in Linksys routers.

The CISA advisory acknowledges the considerable capabilities at Iran’s disposal should the Islamic Republic choose to retaliate in cyberspace.

Farsight Security CEO Paul Vixie talks with CyberScoop Editor-in-Chief Greg Otto about why attackers have focused on DHS hijacking in recent months.

Amb. Robert Strayer said if the recent spate of DNS hijackings are nation-state-baseds, they are no different than any other attacks on critical infrastructure.

Using the DNS records, attackers are capable of rerouting user traffic and stealing credentials from what appears to be a legitimate website.

“We need to understand the scope of this action and how many agencies were actually affected,” Rep. Jim Langevin, D-R.I., told CyberScoop.

DHS wants agencies to clamp down on login credentials after a hacking campaign emanating from Iran.

The campaign is targeting organizations in the Middle East, North America and Europe, researchers say.
