What it detects

This rule detects the Java runtime javaw.exe establishing a network connection to Pastebin, the payload-retrieval behavior Red Canary observed from the signed D3F@CK loader that masqueraded as a Microsoft Teams installer. Java processes reaching out to paste sites are uncommon in enterprise environments, so this pairing indicates second-stage payload download from attacker-hosted text.
