Security audit

Cronexplain

Security checks across malware telemetry and agentic risk

Overview

Cronexplain is a local cron-expression helper with no evidence of hidden access, networking, persistence, or privileged behavior.

Safe to install for casual cron explanation. Do not treat its next-run output as authoritative for production scheduling, audits, or maintenance windows unless you verify edge cases with your actual cron implementation.

Finding
The tool computes and prints 'next run' times as if they were authoritative, but its matching logic only approximates cron semantics, especially around day-of-month/day-of-week behavior. In operational or security-sensitive contexts, this can mislead users about when scheduled jobs will execute, causing missed maintenance windows, incorrect audit conclusions, or unsafe scheduling decisions.
