goals: 1. Formalise a threat model of VTAdmin. 2. Manually audit the VTAdmin code. 3. Manually audit the remaining Vitess code base. 4. Assess and improve Vitessʼs fuzzing suite. 5. Carry out a SLSA compliance modelling: ● Vitessʼs documentation including README files from the Vitess repository ● Vitessʼs source code at https://github.com/vitessio/vitess ● Feedback from Vitess maintainers The threat model is aimed is an individual or group that intentionally attempts to exploit vulnerabilities, deploys malicious code, or compromise or disrupt a VTAdmin deployment, o�en for personal gain, espionage, or sabotage.
