In 21st century, space is the new battlefield

As Russia held its Victory Day parade this year, hackers backing the Kremlin hijacked an orbiting satellite that provides television service to Ukraine.

THE U.S., China and Russia seek control over the moon. Above, a Chinese rocket launch.

Instead of normal programing, Ukrainian viewers saw parade coverage beamed in from Moscow: waves of tanks, soldiers and weaponry. The message was meant to intimidate and was an illustration that 21st century war is waged not just on land, sea and air but also in cyberspace and the reaches of outer space.

Disabling a satellite could deal a devastating blow without one bullet, and it can be done by targeting the satellite’s security software or disrupting its ability to send or receive signals from Earth.

“If you can impede a satellite's ability to communicate, you can cause a significant disruption,” said Tom Pace, chief executive of NetRise, a cybersecurity firm focused on protecting supply chains.

“Think about GPS,” said Pace, who served in the Marines before working on cyber issues at the Department of Energy. “Imagine if a population lost that and the confusion it would cause.”

Satellites pose short-term challenge

More than 12,000 operating satellites now orbit the planet, playing a crucial role not just in broadcast communications but also in military operations, navigation systems such as GPS, intelligence gathering and economic supply chains. They are also key to early launch-detection efforts, which can warn of approaching missiles.

That makes them a significant national security vulnerability, and a prime target for anyone looking to undermine an adversary’s economy or military readiness — or deliver a psychological blow like the hackers supporting Russia did when they hijacked television signals to Ukraine.

Hackers typically look for the weakest link in the software or hardware that supports a satellite or controls its communications with Earth. The actual orbiting device may be secure, but if it’s running on outdated software, it can be easily exploited.
