prova vs Volatility
A side-by-side editorial comparison of prova and Volatility — release velocity, themes, recent moves, and the top alternatives to consider.
prova vs Volatility: at a glance
What is prova?
prova adds expected-utility calculation on top of its Bayesian inference core.
prova does Bayesian nonparametric inference in R — probabilities through Pr() and qPr(), mutual information, quantile plots. Five releases in about two weeks renamed its central argument, collapsed two plotting functions into one, and then in v2.3.0 introduced exputility() for expected utilities and their revisability, with plot() and print() methods attached from the start.
What is Volatility?
Volatility 3 caught up with Volatility 2, then started reorganising itself.
The 2.26.0 release was explicitly aimed at functional parity with the archived Volatility 2, landing around twenty plugins at once across Linux, macOS and Windows. Since then the work has shifted from filling gaps to structuring what exists: malware-specific plugins moved under a malware namespace with the old names deprecated, an arrow/parquet output renderer added, volshell given breakpoints, and per-release additions like sockscan, process_spoofing, pebmasquerade and etwpatch.
prova vs Volatility: editorial side-by-side
prova
6.3INFRA · APIS
prova adds expected-utility calculation on top of its Bayesian inference core.
◆ Current state
prova does Bayesian nonparametric inference in R — probabilities through Pr() and qPr(), mutual information, quantile plots. Five releases in about two weeks renamed its central argument, collapsed two plotting functions into one, and then in v2.3.0 introduced exputility() for expected utilities and their revisability, with plot() and print() methods attached from the start.
◆ Where it's heading
Two arcs run in parallel. One compresses the API: learnt= became K=, flexiplot() and plotquantiles() merged into pplot(), and omitting arguments such as Y=, X= and K= got simpler. The other extends reach — mutualinfoF() for finite-domain variates, quantile accuracy reported alongside mutual information, and now a decision-theoretic layer sitting on the inference the package already did.
◆ Prediction
exputility() shipping with print() and plot() methods matches how the probability and mutual-information classes were treated, so utilities are likely to get the same class-based handling as they mature. The notes do not say whether decision analysis extends beyond expected utility.
Volatility
0.0INFRA · APIS
Volatility 3 caught up with Volatility 2, then started reorganising itself.
◆ Current state
The 2.26.0 release was explicitly aimed at functional parity with the archived Volatility 2, landing around twenty plugins at once across Linux, macOS and Windows. Since then the work has shifted from filling gaps to structuring what exists: malware-specific plugins moved under a malware namespace with the old names deprecated, an arrow/parquet output renderer added, volshell given breakpoints, and per-release additions like sockscan, process_spoofing, pebmasquerade and etwpatch.
◆ Where it's heading
Two things are happening at once. The plugin catalogue keeps growing on the Linux side in particular — tracing, kallsyms, ftrace, VMA scanning, smearing protection — reflecting where memory forensics currently has the least coverage. And the framework is being made into something other tools consume: structured output formats, a shipped Windows executable, a namespaced plugin taxonomy with a year-long deprecation window. The project is treating plugin names as an interface it owes users stability on.
◆ Prediction
Expect the malware namespace migration to complete as the deprecated names age out, and the Linux plugin surface to keep taking the bulk of new additions, with output-format work continuing to open the framework to automated pipelines.
