About
Nullbyte Security Conference is a Brazilian information security event held in Salvador, Bahia, described by its organisers as one hundred per cent focused on offensive security, advanced research and highly technical content. That focus is unusually strict. Where many regional security conferences balance technical research against governance and awareness material, Nullbyte deliberately excludes the softer end entirely, positioning itself for researchers and practitioners who work at the level of exploitation and reverse engineering. The programme seeks original research and practical demonstration across vulnerability research and exploitation, reverse engineering, malware analysis, cloud attack techniques, web application security, hardware hacking, red team operations, cryptographic systems, and the emerging use of artificial intelligence in offensive work. Salvador's position in Brazil's northeast gives the event a regional character distinct from the São Paulo–centred conference circuit, drawing researchers from a part of the country with fewer technical gatherings. For offensive security practitioners, malware analysts and vulnerability researchers in Brazil, Nullbyte offers a rare venue for deeply technical work without dilution.

Planning your trip to Salvador
Contains sponsored linksNullbyte meets in Salvador in early November, at the start of the Bahian hot season: twenty-nine degrees, high humidity and short heavy showers that clear within the hour. This was Brazil's first capital, and its historic upper town is the densest concentration of Portuguese colonial architecture in the Americas, sitting on a cliff above the bay. The security community here is long-established and the conference has a distinctly local character.
Getting there & around
Salvador's airport (SSA) is about 25 kilometres from the centre, roughly 30 to 40 minutes by road to Barra or the Pelourinho depending on traffic. Metro Line 2 connects the airport to Acesso Norte, where a transfer continues toward the centre. Ride-hailing apps operate from the terminal and are cheaper and more predictable than airport taxis.
Skip the taxi queue — pre-book a fixed-price airport transfer with Kiwitaxi. Exploring beyond the city? compare rental cars on EconomyBookings.
Staying connected
Coverage in Salvador's central and coastal districts is reliable, though the steep terrain creates gaps. Brazilian prepaid SIMs require a local tax number, which makes an eSIM arranged before arrival much simpler for foreign attendees. Set up an eSIM with Airalo before you board and you're online the moment you land.
After the sessions
Pelourinho. The colonial upper town is a grid of pastel townhouses, baroque churches and steep cobbled squares, restored as a heritage district and full of drumming groups and capoeira circles. Two hours covers the core. It is best in daylight and on the busier streets; the quieter lanes are worth avoiding after dark.
Elevador Lacerda and Mercado Modelo. An art deco lift has connected the upper and lower towns since 1873, dropping seventy metres for a few centavos and depositing passengers beside the Mercado Modelo craft market on the bay. The ride takes under a minute and the view across the Baía de Todos os Santos is the reason to take it.
Porto da Barra and Farol da Barra. A sheltered bay beach in the Barra district faces west, which makes it one of the few places in Brazil where the sun sets over the water. The lighthouse at the point houses a nautical museum. Locals arrive in the late afternoon; the swimming is calm and shallow.
Igreja de São Francisco. Behind a restrained facade lies an interior almost entirely covered in gilded wood carving, one of the most extravagant baroque interiors anywhere. Entry is ticketed and takes about forty minutes with the adjoining cloister of blue Portuguese tilework. It sits in the middle of the Pelourinho.
Good to know
What is the weather like in early November?
Hot and humid, with highs near 29°C and short intense showers most days as the rainy season approaches. Light clothing, sun protection and a compact rain layer are all needed.
What should visitors know about getting around safely?
Stick to busier streets in the historic centre, particularly after dark, and use ride-hailing apps rather than walking between districts at night. Leave valuables in the hotel and carry only what is needed for the day.
How should payments be handled?
Cards are accepted widely and contactless is standard, but market stalls, beach vendors and the elevator want small amounts of cash. Brazil's instant-payment system is universal locally but generally needs a domestic bank account.
