What is OpenCTI?

OpenCTI spends a release unblocking queues and hardening upserts

7.260817.0 is a fix release. The most consequential item is malformed STIX messages nacking forever and blocking worker queues indefinitely — a stall in the ingestion path rather than a display bug. Alongside it: upsert clearing an existing createdBy when incoming confidence is higher, draft upserts crashing on existing attack patterns, OTP handling in the stream middleware, and case template relation authorization. Score fields were added to threat actor groups, intrusion sets and malware.

What is serofoi?

serofoi grew a serosurvey simulator alongside the force-of-infection models it was built to fit.

serofoi estimates the force of infection from serological survey data using Bayesian serocatalytic models fitted through Stan. Beyond fitting it now simulates serosurveys — specifying a model and a survey design and generating the data such a survey would produce. The most recent release is visualisation and naming work.

OpenCTI spends a release unblocking queues and hardening upserts

◆ Current state

7.260817.0 is a fix release. The most consequential item is malformed STIX messages nacking forever and blocking worker queues indefinitely — a stall in the ingestion path rather than a display bug. Alongside it: upsert clearing an existing createdBy when incoming confidence is higher, draft upserts crashing on existing attack patterns, OTP handling in the stream middleware, and case template relation authorization. Score fields were added to threat actor groups, intrusion sets and malware.

◆ Where it's heading

The platform's feature energy went into the connector catalog and integrations rework in July, and the releases since have been consolidating: mass operations on relation times, shareable saved searches, and now a pass over ingestion robustness. Adding score to more entity types continues the slow enrichment of the data model that runs underneath the feature work.

◆ Prediction

Given score arriving on three entity types in one release, expect it to keep spreading across the data model, and the queue-blocking class of bug to draw more worker-side hardening.

serofoi grew a serosurvey simulator alongside the force-of-infection models it was built to fit.

◆ Current state

serofoi estimates the force of infection from serological survey data using Bayesian serocatalytic models fitted through Stan. Beyond fitting it now simulates serosurveys — specifying a model and a survey design and generating the data such a survey would produce. The most recent release is visualisation and naming work.

◆ Where it's heading

The package moved from fitting-only to a fit-and-simulate pair. 0.1.0 added simulation from time- or age-varying force-of-infection trends and simplified the fitted object down to a Stan fit; 1.0.2 broadened simulation into full serosurvey generation with its own vignette. 1.0.3 then spent its effort on naming consistency and plotting options, which is what a package does once its scope is set.

◆ Prediction

With simulation and fitting both in place, the natural next step is tooling that closes the loop between them — recovery checks or study-design guidance built on simulated surveys.
