Software Engineering Events in Krakow

Hey everyone,
Join us for an Offensive Night focused on how attackers actually think, move, and break things—and how we respond.

This evening brings together creative red teaming tactics and a hands-on vulnerability demo, designed for security engineers, developers, and anyone curious about the offensive side of security.

Agenda

• 17:00 Doors open
• 17:30 Live virtual speaker: Steve Borosh
  Continuous Offensive Recon: Tightening the OODA Loop with AI-Driven Data Enrichment for Red Team Operations
  Traditional penetration tests, assumed-compromise assessments, and red team engagements still treat reconnaissance as a discrete, time-boxed phase at the beginning of the assessment. In reality, modern environments change hourly, files change, credentials rotate, people join and leave, and defensive controls evolve. Static recon snapshots quickly go stale, forcing operators to restart the intelligence cycle under pressure. This talk presents Continuous Offensive Recon as the solution: a persistent, closed-loop intelligence capability that provides offensive operators with actionable intelligence at every phase of the assessment.
  Raw data from passive recon, active scanning, file share searching, C2 exfiltration, user behavior, and open-source intelligence is abundant. What separates elite operators is the ability to continuously enrich that data, surface hidden relationships between obscure technical and human data points, and convert noise into prioritized, high-fidelity attack paths in near real time.
  We will walk through exactly how to build and operate this capability using a practical, open-source-heavy stack that the audience can start implementing immediately:
  With the industry moving towards more “Continuous Penetration Testing” as BHIS has adopted, offensive operators are moving from periodic assessments to a living, intelligence-gathering assessment that paired with the OODA loop decision cycle, and continuous reconnaissance, keeps operators ahead of their target networks.
• 18:30 intermission
• 19:00 in-person speaker: Julian B. Let Him Cook! Hacking the Meatmeet BBQ Probe
  With grilling season upon us, each and every grillmaster is eagerly preparing their tools… but little do some know, their “smart” meat probes may have some glaring vulnerabilities that could leave them cooked. In this presentation we will disassemble, dump the flash, and decompile the mobile application of the Meatmeet BBQ probes to find countless vulnerabilities. From an open S3 bucket with the profile photo of every grill master, poorly salted passwords, to never-before-seen devices, and even remote code execution, Julian will walk you through the platter of vulnerabilities he found. This will illustrate the importance of IoT security, because the last thing you want is for your beautiful BBQ to be burnt to a crisp! As a Senior Penetration Tester at Software Secured, Julian hunts for vulnerabilities across a range of clients and products. Off hours, he spends his time performing vulnerability research against IoT devices and FOSS, amassing over 50 CVEs in the past several years. Previous work includes exploiting the Furbo devices, to find 20+ vulnerabilities, discovering more than 130,000 Claude, Grok, ChatGPT, and Other LLM Chats Readable on Archive.org (https://www.404media.co/more-than-130-000-claude-grok-chatgpt-and-other-llm-chats-readable-on-archive-org/), as well as being featured by 404Media in the article: Grok Exposes Underlying Prompts for Its AI Personas: ‘EVEN PUTTING THINGS IN YOUR ***’ (https://www.404media.co/grok-exposes-underlying-prompts-for-its-ai-personas-even-putting-things-in-your-ass/)

THE TALKS:
Oleg Szydłowski - AI agents orchestration with python [EN]

The usual way to wire sub-agents together puts an orchestrator LLM in charge of deciding what to call next — flexible, but non-deterministic: the same goal takes a different path every run, and long loops drift as context fills up. This talk shows a different approach: compile the goal into an explicit control-flow program once, then let deterministic code on python — not a model — drive every branch, retry, and loop, while the LLM just does the work at each node. The result is orchestration that's reviewable, reproducible, and bounded by construction, with a log that lets a crashed run resume exactly where it stopped.

Maria Lowas-Rzechonek - Wszystko, co musicie wiedzieć o docstringach, ale nie chcecie zapytać [PL]

Pamiętacie pierwszą klasę szkoły podstawowej i żmudne rysowanie szlaczków w zeszytach, żeby oddzielić jeden temat lekcji od drugiego? Wielu z nas kiedy dorosło, zamieniło zeszyty w linie na Pycharma, ale nawyki pozostały. Spójrzmy prawdzie w oczy: dla większości programistów pisanie docstringów to właśnie takie dorosłe „szlaczki”. Nużący obowiązek i wizualny wypełniacz, którego jedynym celem jest oddzielenie sygnatury funkcji od jej implementacji.
Większość z nas żyje w przekonaniu, że dobry kod dokumentuje się sam, a pisanie potrójnych cudzysłowów to strata czasu. Efekt? Albo nie piszemy ich wcale, albo generujemy automatyczne potworki, które informują świat, że funkcja get_user_id(user) służy do... get user id.
Przyjdź, jeśli nienawidzisz pisać dokumentacji. Obiecuję, że po tej prezentacji nadal możesz jej nienawidzić, ale przynajmniej pisanie jej stanie się mniej bolesne i do rzeczy!

Nightack to wydarzenie w którym uczestniczą osoby zarówno będące aktywnymi członkami hackerspace, jak i te które chciałyby dowiedzieć się jak hackerspace działa i co tutaj robimy.
Jesteśmy dla Was dostępni od 20:00, ale nie musicie wcale przchodzić punktualnie!

== Co robimy na nighackach? ==

Pracujemy nad własnymi projektami - np. ktoś frezuje radiator do komputera aby mógł w nim zmieścić rezystor dużej mocy, składa małego satelitę "CanSat" na konkurs, a w kolejnym siedzimy i rozmawiamy na wszelkie tematy w przyjaznej, aczkolwiek geekowej atmosferze.

== Kto może przyjść? ==

Każdy! Nie ma znaczenia czy jesteś elektronikiem hobbystą, spawasz zawodowo, czy też chciałbyś się jedynie dowiedzieć jak równo powiesić półkę - miło będzie nam Ciebie gościć.

== Nie mam projektu nad którym mógłbym pracować, czy to problem? ==

Zdecydowanie nie, chętnie Cię oprowadzimy, pokażemy co robimy, porozmawiamy, może się czymś zainspirujesz.

== Czy muszę być punktualnie o 20? ==

Będziemy w hackerspace co najmniej do północy - NightHack nie jest ustrukturyzowanym wydarzeniem, więc godzina o której przyjdziesz nie ma znaczenia.

== Co zrobić po dotarciu na miejsce? ==

Jeśli jesteś pierwszy raz to poszukaj organizatorów - najlepiej spytaj o nich pierwszą napotkaną osobę.

== Czym jest Hackerspace? ==

Hackerspace to przestrzeń stworzona i utrzymywana przez grupę osób, które łączy fascynacja ogólnopojętym tworzeniem w duchu kultury hackerskiej. Przestrzeń stymuluje rozwój projektów między innymi organizując i użyczając potrzebnych narzędzi stwarzając warunki do wzajemnej nauki. Hackerspace nie zna barier, jeśli masz ciekawy pomysł i szukasz ludzi chętnych do współpracy lub po prostu potrzebujesz miejsca i sprzętu - zapraszamy!

== Chciałbym o coś zapytać, jak mogę to zrobić? ==
