What is beacon jitter in malware?

Adversaries add random percentage variance (jitter) to callback intervals (e.g. 60s ± 20%) to evade simple periodic timer detection algorithms.

How does this tool detect jittered beacons?

It computes delta clustering, variance distribution, and Shannon entropy over time deltas; even randomized malware exhibits recognizable statistical boundaries.

What is Coefficient of Variation (CV)?

CV = standard deviation / mean. Human browsing has high CV (> 1.0); malware beacons with jitter typically exhibit low to moderate CV (0.1 to 0.4).

Are my enterprise logs uploaded to your server?

No. All timestamp calculations, histograms, and statistical tests execute 100% inside your browser's local sandbox.
