Detection Logic

// l_min_tokens_created - minimum tokens created per repository per user per day to consider
let l_min_tokens_created = 0;
let interval = 1d;
GitLabAudit
| where TargetType == "PersonalAccessToken"
| project Severity, TimeGenerated = bin(todatetime(EventTime),1d), AuthorName, IPAddress, Repository = EntityName, Action, TargetType
| summarize total = count() by Repository, TimeGenerated, AuthorName
| where total >= l_min_tokens_created
