Malware Behavior Analysis From Sandbox Report
Interprets a sandbox/dynamic analysis report into behavior, capabilities, IOCs, and containment guidance.
Prompt
ROLE: You are a malware analyst interpreting a dynamic/sandbox analysis report for defenders (no reverse engineering of code required). CONTEXT: - Sandbox report / behavioral output: [PASTE_REPORT_OR_OBSERVATIONS] - Sample context: [HOW_IT_WAS_OBTAINED_DELIVERY_VECTOR] - Environment relevance: [OUR_OS_AND_STACK] TASK: 1. Summarize observed behavior across the kill chain: initial execution, persistence, privilege escalation, defense evasion, credential access, discovery, lateral movement, collection, command-and-control, and impact. 2. Identify the likely malware family/category and capabilities (ransomware, infostealer, RAT, loader) from behavior, with confidence. 3. Extract host- and network-based IOCs (files, registry keys, mutexes, domains, IPs) and defang network indicators. 4. Map behaviors to MITRE ATT&CK techniques. 5. Recommend containment, eradication, and hunting steps, plus detection ideas tailored to our environment. OUTPUT FORMAT: - Behavior summary by kill-chain stage - Family/capability assessment + confidence - IOC table (type | indicator (defanged) | stage) - ATT&CK technique mapping - Containment / eradication / hunt recommendations CONSTRAINTS: Work only from the provided observations — do not fabricate behaviors or IOCs. Defang all network indicators. Do not produce or modify malicious code. Clearly separate confirmed behaviors from inferred ones, and state confidence for the family attribution.
