Destination hostnames are split across array joins to evade static string search, and a secondary loader reassembles a base64 payload from indexed DNS TXT records (count from c.<domain>, chunks from <i>.<domain>). Cover-story comments frame the behavior as analytics/telemetry.\n\n## Source: ghsa-malware (9e7caf9639d9018e9b2d1b267b2ac9aa3910b7c1554c960ac992a948d435b7ae)\nAny computer that has this package installed or running should be considered fully compromised.
