Vilnius Offensive
Security Meetup
hosted by Offensive360
Vilnius has a serious security industry and no room where the people who break things get together on purpose. So we are making one.
Two evenings: a talks night and a CTF night. Free to attend, vendor-pitch free, beginners genuinely welcome. First edition: Wednesday 18 & Thursday 19 November 2026, 18:00–22:00, in Vilnius.
// status: the dates are fixed. We are finalising a venue with a proper projector, presentation setup and enough network and power for a room full of laptops — everyone registered gets the address by email first, before it is announced anywhere else.

Why this, why now
Lithuania runs a dense, technically strong security scene — a national CERT, a fintech sector that gets attacked constantly, and some of the best-known privacy and infrastructure companies in Europe. There are excellent local events for the industry, and a conference once a year. What there isn't is a regular, informal room specifically for the offensive side of the craft: exploitation, red teaming, bug hunting, tooling, and the awkward findings you can only talk about among people who have written the same report.
This meetup is that room. Small, technical, recurring, and free. The format stays deliberately simple so it can survive: a couple of talks, a CTF you can actually finish in an hour, and enough time to talk to strangers. If it works, it happens every quarter and grows into something Vilnius keeps.
Hosted and funded by Offensive360. The company pays for the room and the food; it does not get the stage. Talks are chosen on technical merit by the community, and sales pitches are not talks.

We solve every challenge on the screen and explain how. The walkthrough is the point — it is where the learning actually happens.

Questions
Who is this meetup for?
Anyone who breaks, defends, or builds software in Lithuania: penetration testers, red and blue teamers, bug bounty hunters, appsec and DevSecOps engineers, SOC analysts, CTF players, students, and developers who want to understand how their code gets attacked. No certifications required, no gatekeeping. Curiosity is the entry ticket.
What does it cost?
Nothing. Attendance is free. Offensive360 covers the venue, the pizza, and the drinks — no ticket, no upsell pitch from the stage, no vendor booth. Sponsorship exists to pay for the room, not to buy the microphone.
What language are the talks in?
English by default, so newcomers to Lithuania and international speakers can take part. Lithuanian talks are welcome — indicate your preference when you submit and we will label it clearly on the schedule.
Can I speak if I have never given a talk before?
Yes, and we actively want you. Every meetup keeps slots for first-time speakers and 10-minute lightning talks. A CVE you found, a box you rooted, a bypass you built, a failure you learned from — that is a talk. We will help you rehearse and shape the deck if you want the help.
What can I not talk about?
No live attacks on systems you do not own or have written permission to test, no dumping other people's data, no unpatched zero-days in products where the vendor has not been given a fair disclosure window, and no vendor sales pitches. Responsible disclosure stories are very welcome — the responsible part is the interesting part.
When and where exactly?
Wednesday 18 and Thursday 19 November 2026, 18:00 to 22:00 both evenings, in Vilnius. Two evenings rather than two full days, deliberately: you can come straight from work, and you can come to one night or both. The dates are fixed. We are finalising a venue that can do proper presentations and handle a room full of laptops for the CTF — everyone registered gets the address by email before it is public.
Is there a code of conduct?
Yes. Be decent to people. Harassment, discrimination, and unsolicited recording of other attendees get you removed, with no debate. The community is meant to be the kind of room where a student can ask a basic question next to a principal engineer and nobody smirks.
Can my company sponsor or host?
Get in touch. We need an evening room for up to 100 people on 18 and 19 November, food and drink sponsors, and help with CTF infrastructure. Sponsors get a thank-you from the stage and a logo on the page — not a speaking slot. Email [email protected] with "Vilnius meetup" in the subject.
Want to host, sponsor, or help run it?
We are looking for venues for ~100 people, food sponsors, and people who want to co-organise. A community with one organiser is a community with a single point of failure.
