JavaScript & Macro Detection
Malware often hides in legit-looking documents using embedded JavaScript (PDFs) or VBA Macros (DOCX, XLSX). We statically extract and analyze this code before it can ever execute.
Hidden Object Streams
PDFs can contain compressed or encrypted object streams designed to evade simple string-matching antivirus engines. We deeply parse the file structure to expose what's inside.
Zero-Day Heuristics
By analyzing the behavior intended by the document (like `AutoOpen` or `/Launch` tags), we can detect suspicious intent even if the exact threat signature has never been seen before.
Embedded File Extraction
Attackers embed malicious executables inside seemingly harmless PDFs or Office documents. Our engine identifies and flags these nested payloads instantly.
Multi-Engine Consensus
Why rely on one antivirus? We instantly check document hashes against three premier threat intelligence feeds (Cymru, MalwareBazaar, CIRCL) for a unified verdict.
Actionable Insights
Instead of a black-box 'Failed' message, we provide exact structural triggers, hexadecimal block counts, and tags so security analysts can understand the threat.
