Good to know:
Date: September 16, 2025
json-rules-engine-simplified package was compromised to include malicious code that steals github secrets, using them to create malicious github actions workflows that help exfiltrate even more github secrets. Besides, the malicious code also uses a data collection endpoint using webhook.site to collect all the stolen data. We recommend downgrading it to 0.1.17 https://thehackernews.com/2025/09/40-npm-packages-compromised-in-supply.html
