"a systematic #cybersecurity assessment of a #digitalsubstation…A testbed was developed to assess the different attack vectors with a focus on targeting #virtualmachines #resourceexhaustion and #injectionattacks…use case was successfully demonstrated with multiple targeted cyber attacks on the testbed where the non-attacked IED successfully cleared the grid fault."

The implemented hybrid setup, as seen in Fig. 2, includes a distance protection physical IED from a typical vendor and a virtual IED with an instantaneous overcurrent protection acting as a primary relay within a smaller containment zone. A distance protection algorithm works by measuring a power line’s impedance and comparing it to a preset characteristic value. In case of a fault, the line’s impedance value falls outside the admissible range. A zone setting is also configured for each IED. Different zone settings have different operating times (time delays) for clearing the fault. The overcurrent protection should operate before the distance protection operates, thereby ensuring a hybrid (physical/virtual) protection selectivity.

Ars Technica: Address bar shows hp.com. Browser displays scammers’ malicious text anyway.. “Tech support scammers have devised a method to inject their fake phone numbers into webpages when a target’s web browser visits official sites for Apple, PayPal, Netflix, and other companies. The ruse, outlined in a post on Wednesday from security firm Malwarebytes, threatens to trick users into […]
