# Lunes 15/12 14hs - Seminario “Gathering Threat Intelligence from Encrypted Network Traffic” Prof. Ondřej Ryšavý, Brno University of Technology (BUT), República Checa.
Tenemos el agrado de invitarlos a la charla que brindará el Prof. Ondřej Ryšavý que nos visita desde la Brno University of Technology (BUT) de la República Checa.
Esta visita se da en el marco de una cooperación activa entre BUT y el DC/ICC en temas de seguridad informática (aunque no exclusivamente), con lo cual este seminario es también una oportunidad para aquellos investigadores, docentes y alumnos que deseen sumarse a las iniciativas en curso.
🗓 lunes 15 de diciembre
🕑 14:00 hs.
📍 Sala 1606, Pabellón 0+infinito, Ciudad Universitaria, Buenos Aires, Argentina. geo:-34.54396,-58.44038?z=16

Título: Gathering Threat Intelligence from Encrypted Network Traffic
Abstract: Encrypted communication now dominates network environments, reducing the visibility of defenders and demanding new approaches that derive security intelligence without decrypting content. This presentation unifies three complementary research directions into a single, end-to-end framework for threat identification, behavior profiling, and malware attribution.
First, it introduces a privacy-preserving methodology for latent behavior modeling of TLS traffic. This methodology uses autoencoder-based profiling, extended flow-level metadata, and federated learning for distributed training across sites. The results demonstrate that encrypted traffic can be characterized statistically and semantically without access to the payload, enabling scalable anomaly detection while reducing the risk of data exposure. The second part focuses on threat detection through IoC-driven context enrichment. In this approach, Indicators of Activity (IoAs) extracted from hosts are matched against fuzzy IoC sets derived from malware. This enables family-level correlation, threshold-based scoring, and experimentation in semi-controlled infected environments. Lastly, the presentation explores JA3/JA4+ TLS fingerprinting as a higher-resolution layer for application and malware discrimination. An experimental evaluation using sandbox-generated datasets reveals patterns of uniqueness, coverage, and collisions across multiple malware families and benign applications. This demonstrates how fingerprinting can facilitate attribution and classification in encrypted networks.

📚 UNIPOP ZAM: Prendiamoci i saperi! (con lectio di Francesca Coin e live di Calogero Incandela)
Domenica 6 luglio, dalle 17:30 alle 23:00, presso ZAM, Milano, via Sant'Abbondio 4
📣 Grande Annuncio 📣
Domenica 6 luglio presso ZAM si terrà il lancio ufficiale del secondo Anno Accademico della nostra Università Popolare!
Analizzeremo questa bellissima esperienza a quasi un anno di distanza dalla sua nascita, presenteremo i nuovi corsi e tutte le novità che abbiamo pensato per voi. Non vediamo l’ora! ✨📚🧨
Per farlo al meglio, avremo l’onore di ospitare Francesca Coin che terrà una breve lectio sulla destra americana 🎓
CenaPop a cura della q-cina ZAM 🌱
A seguire, musica live con Calogero Incandela 🎶
“Dopo ‘Tutti ostentammo a stento’, ‘Radiofeccia’, ‘Orizzonti di Boria’, Calogero Incandela sta per giungere propizio al suo quarto album che uscirà a breve: ‘Strazi di vita quotidiana’. Ma non prima di viaggi solitari in bicicletta per le campagne irrorate dal sole estivo senza tempo in compagnia di compagni di sventure, nel ricorso di giovanili entusiasmismi in cui scarponi chiodati la facevano da padrone tra i boy scout.”
Non prendete impegni. Vi aspettiamo dalle 17:30! 🔥
