MicroStealer Analysis: A Fast-Spreading Infostealer with Limited Detection 

MicroStealer is an actively observed infostealer that uses a layered NSIS → Electron → Java (JAR) delivery chain to harvest browser credentials, session tokens, screenshots, and crypto wallet files, then exfiltrates data via Discord webhooks and attacker-controlled servers; the report provides static and dynamic analysis, persistence and privilege escalation behavior, anti-analysis checks, full IOCs (hashes, domains, webhook URL, API key), and MITRE ATT&CK mappings to aid detection and hunting.
