npm indexed-btree BTree.prototype.set runtime loader trigger
Detects the execution and behavioral patterns associated with the malicious 'indexed-btree' npm package. The rule specifically looks for code patterns where a malicious loader is injected into 'BTree.prototype.set' and triggered at runtime. It also monitors for suspicious process spawning behavior, such as running node processes with detached and hidden windows flags, often used by the package to maintain persistence or execute malicious payloads silently.
