On our side, we have identified: Malware in fsevents · GHSA-xv2f-5jw4-v95m · GitHub Advisory Database · GitHub
Our malwares are all NPM/fsevents things.
Nexus gets its data from https://rhc.sonatype.com/rest/rhc/extras/maliciousContent/{NEXUS_ID} (can be finded on logs) => it allows to identify the registry.
Then, we have scraped malware databases of GitHub: GitHub Advisory Database · GitHub
And for each entry, we have used Nexus API to check if we have one: https://it-dev-fr-nexus.intramatch.eu:8080/service/rest/v1/search?repository=npm-registry&name={MALWARE_COMPONENT}.
=> ~ 50 were identified (among 18000).
Finally, we have checked group/version one by one to identify fsevents
