K8S Lecture 24: Introduction to Chaos Engineering - Core Features of Chaos Mesh and Fault Injection

1. Introduction: Why is Chaos Engineering Needed? In the cloud-native era, system complexity is growing exponentially, and traditional testing methods can no longer cover all failure scenarios. Chaos Engineering is a proactive experimental approach that injects faults to help us discover system weaknesses before real failures occur in production environments. As a CNCF incubated project, … Read more

Dissecting the Chevrolet Heavy-Duty Pickup ECU: How a ‘Hacker’ Breached the ‘Unhackable’

Dissecting the Chevrolet Heavy-Duty Pickup ECU: How a 'Hacker' Breached the 'Unhackable'

Five years ago, a new adjustable ECU/ECM claimed to be “unhackable” and dominated the market at that time; it was the GM E41 ECM Services (L5P). This ECU/ECM first appeared on the L5 Peter Max truck in 2017, and many believed that such ECUs/ECMs could not be hacked or tuned. As experts from the external … Read more
