FEFCS V12 Engine => Website security Observatory
Fractional Exact Flow Computing System — structural detection via exact fractional analysis, proposed by Miguel Vidal Bravo-Jandia. V12 architecture: PE V10 layer (native MZ/PE parsing + sections) + 4 V11 cycles (global fractional analysis). The al-jabr and al-muqabala principles of Al-Khwarizmi have been integrated.
How FEFCS V12 works
Exact Fractions
No modulo operation. No floating point. The engine operates exclusively in exact fractions — an approach proposed by Miguel Vidal Bravo-Jandia. Integrated alongside Al-Khwarizmi's al-jabr and al-muqabala principles, which structure the restoration and balancing of values. Rounding error does not exist.
Structural Detection
FEFCS never compares a file to a known database. It measures the intrinsic mathematical balance of each binary section — a coherence that every malware structurally destroys, regardless of its obfuscation. Zero signatures. Zero database. Zero external connection during analysis.
PE Granularity
Each PE section (.text, .data, .reloc…) is analyzed independently. A malware concealing its payload in .data is detected where it hides, not only at the global file level. The result is traceable, reproducible and explainable — without ever executing the file.
What is a PE malware?
PE = Portable Executable — the format of Windows executable files: all .exe, .dll, .sys, .scr. Windows' native format since 1993, it has not fundamentally changed since.
This is by far the most widespread malware format in the world. WannaCry, Emotet, Mirai, Stuxnet, modern ransomware, banking trojans, RATs, password stealers — virtually everything distributed by malware databases is predominantly PE. Security researchers estimate that over 70% of malware active in the wild are Windows PE binaries.
The reason is simple: Windows accounts for ~72% of the global desktop market. Targeting Windows in PE means targeting the maximum number of potential victims.
FEFCS V12 targets precisely this segment — the densest and most dangerous part of the global cyber threat. This is the core problem the entire antivirus industry has been trying to solve for 30 years.

V12 Architecture
ZIP Peek
Double extension detection and abnormal ZIP content before any in-depth analysis.
PE V10 Analysis
Native MZ/PE parsing. Section-by-section analysis (.text, .data, .reloc…). Structural UPX detection.
4 V11 Cycles
Global fractional analysis on the entire file. Covers non-PE types and completes PE analysis.
Infrastructure: dedicated VPS, hosted in Germany. Zero external connection during analysis. Traceable and reproducible fraction result.
Deployment & Scope
FEFCS V12 analyzes all files uploaded to digital-synapse-exchange.com — gallery, writing, shared files, MASP. Active protection in production.
Around 90% detection on more than 11,000 real PE samples (MalwareBazaar / abuse.ch). A dedicated threshold reduces false positives on PDF and Office documents.
Publication of the complete benchmark methodology. Planned extension to interpreted scripts and ELF binaries. Windows, Linux and Android versions planned.
