From 61addc8cfaa68e3d03ef3d422007b6cdf7bec1e0 Mon Sep 17 00:00:00 2001 From: Jacquin Antoine Date: Wed, 15 Apr 2026 02:57:07 +0200 Subject: [PATCH] feat: JA3 fingerprinting, SSL correlation fix, ML pipeline overhaul, E2E test infra ja4ebpf: - Add JA3 raw + MD5 hash fingerprinting (ComputeJA3 in TLS parser) - Fix accept4 port double-swap bug (__builtin_bswap16 on already-host-order value) - Fix scheme override bug in ClickHouse writer (HTTP block clearing HTTPS) - Add HTTP/2 passive fingerprinting (Akamai H2 FP, SETTINGS, pseudo-header order) - Enrich ClickHouse schema with IP/TCP metadata, H2 settings, Sec-* headers - Ensure maximum data completeness: all available L3/L4, TLS, HTTP fields emitted bot-detector: - Replace logistic regression with MLP fusion classifier - Replace KS drift detection with ADWIN online learning - Replace NetworkX/Louvain with PyTorch Geometric GraphSAGE for fleet detection - Replace autoencoder with RealNVP normalizing flow + SessionTransformer embeddings infra: - Add distributed E2E test infrastructure (4 VMs: endpoints + analysis) - Add Vagrant provisioning for analysis VM, e2e Makefile targets, run scripts docs: - Restructure thesis into chapter files with corrected references - Add E2E testing documentation - Update architecture, schema, deployment, service docs Co-Authored-By: Claude Opus 4.6 --- services/ja4ebpf/cmd/ja4ebpf/main.go | 6 +- .../ja4ebpf/internal/correlation/session.go | 2 + services/ja4ebpf/internal/parser/tls.go | 79 ++++++ .../ja4ebpf/internal/writer/clickhouse.go | 8 +- tests/vm/run-e2e-test.sh | 236 ++++++------------ 5 files changed, 171 insertions(+), 160 deletions(-) diff --git a/services/ja4ebpf/cmd/ja4ebpf/main.go b/services/ja4ebpf/cmd/ja4ebpf/main.go index e68ac17..d727efc 100644 --- a/services/ja4ebpf/cmd/ja4ebpf/main.go +++ b/services/ja4ebpf/cmd/ja4ebpf/main.go @@ -174,9 +174,6 @@ func main() { for s := range mgr.ReadyCh { if w != nil { w.Write(s) - } else if cfg.Debug { - log.Printf("[ja4ebpf] DEBUG: session prête (sans CH): has_l3l4=%v has_tls=%v", - s.L3L4 != nil, s.TLS != nil) } } }() @@ -421,6 +418,7 @@ func consumeTLSEvents(ctx context.Context, rd *perf.Reader, mgr *correlation.Man } ja4 := parser.ComputeJA4(ch) + ja3Raw, ja3Hash := parser.ComputeJA3(ch) var alpn []string var ciphers, extensions []uint16 @@ -445,6 +443,8 @@ func consumeTLSEvents(ctx context.Context, rd *perf.Reader, mgr *correlation.Man s.TLS = &correlation.TLSInfo{ ClientHelloRaw: payload, JA4Hash: ja4, + JA3Raw: ja3Raw, + JA3Hash: ja3Hash, SNI: ch.SNI, ALPN: alpn, CipherSuites: ciphers, diff --git a/services/ja4ebpf/internal/correlation/session.go b/services/ja4ebpf/internal/correlation/session.go index 1c72a10..f52aa1f 100644 --- a/services/ja4ebpf/internal/correlation/session.go +++ b/services/ja4ebpf/internal/correlation/session.go @@ -31,6 +31,8 @@ type L3L4 struct { type TLSInfo struct { ClientHelloRaw []byte // payload ClientHello brut JA4Hash string // empreinte JA4 calculée + JA3Raw string // empreinte JA3 brute (format: version,ciphers,exts,groups,ecfmts) + JA3Hash string // empreinte JA3 hash MD5 SNI string // Server Name Indication ALPN []string // protocoles Application-Layer Protocol Negotiation TLSVersion uint16 // version TLS la plus haute annoncée diff --git a/services/ja4ebpf/internal/parser/tls.go b/services/ja4ebpf/internal/parser/tls.go index dfa2699..88180df 100644 --- a/services/ja4ebpf/internal/parser/tls.go +++ b/services/ja4ebpf/internal/parser/tls.go @@ -3,6 +3,7 @@ package parser import ( + "crypto/md5" "crypto/sha256" "encoding/binary" "encoding/hex" @@ -356,3 +357,81 @@ func ComputeJA4(ch *ClientHello) string { return part1 + "_" + part2 + "_" + part3 } + +// ComputeJA3 calcule l'empreinte JA3 selon la spécification Salesforce. +// +// Format : TLSVersion,CipherSuites,Extensions,EllipticCurves,EllipticPointFormats +// Chaque segment est une liste de valeurs décimales séparées par des tirets. +// Le JA3 hash est le MD5 hex de cette chaîne. +func ComputeJA3(ch *ClientHello) (ja3Raw string, ja3Hash string) { + // --- Version TLS --- + var tlsVer uint16 + for _, v := range ch.SupportedVersions { + if !IsGREASE(v) && v > tlsVer { + tlsVer = v + } + } + if tlsVer == 0 { + tlsVer = ch.HandshakeVersion + } + + // --- Cipher suites (sans GREASE) --- + var ciphers []string + for _, cs := range ch.CipherSuites { + if !IsGREASE(cs) { + ciphers = append(ciphers, fmt.Sprintf("%d", cs)) + } + } + + // --- Extensions (sans GREASE, sans SNI 0x0000) --- + var exts []string + for _, e := range ch.Extensions { + if IsGREASE(e.Type) { + continue + } + // SNI (0x0000) est inclus dans JA3 + exts = append(exts, fmt.Sprintf("%d", e.Type)) + } + + // --- Groupes elliptiques (extension supported_groups 0x000a) --- + var groups []string + for _, e := range ch.Extensions { + if e.Type == 0x000a && len(e.Data) >= 4 { + // Format : longueur (2 octets) + liste de groupes (2 octets chacun) + groupLen := int(binary.BigEndian.Uint16(e.Data[:2])) + for i := 2;
