Grayback in action
A quick look at how we find and fix real vulnerabilities.
From first test to fix
Every report's journey, from detection to reward: a traceable cycle with expert triage at each step.
Submitted
The bug hunter reports the vulnerability through Grayback. The finding is logged with a unique identifier and a timestamp.
In triage
Grayback reviews the scope, impact, report quality and initial reproducibility. Clarifications may be requested, or false positives and out-of-scope reports discarded.
Validated
The vulnerability is reproduced and technically confirmed. The flaw type is classified and the final severity is assigned.
Accepted
The company officially acknowledges the finding, confirms the severity and commits to resolving it.
Reward approved
The reward or recognition tied to the report is determined and approved, pending payment or delivery.
