Enabling Light-Injection Attacks by Application of External Magnetic Felds
Enabling light-injection attacks through the application of external magnetic fields represents a method where manipulation of the optical components, such as an optical isolator or circulator, can lead to abnormal functionality and allow subsequent THA attacks by injecting a pulse.
