From Cosmos:

SYDNEY: 'Killer electrons' - electrons circling Earth that wreck satellites and can cause cancer in astronauts - are created when Solar storms create shockwaves in the Earth's protective magnetic bubble, scientists said.

The Earth's magnetic field abounds with charged, fast moving particles that orbit up to 64,000 km above the surface. When a severe solar storm - a stream of energetic particles emanating from the Sun - hits the Earth's magnetic field, it creates a shockwave that boosts the number of particles by up to ten times as much.
