Welcome to the OWASP Lisboa chapter

Welcome to the new OWASP Lisboa OWASP chapter. This new portuguese local chapter, builds on the previous experience of the previous existing portuguese OWASP chapter, that was active between 2008 and 2018.

The objective of this chapter is to promote application security in Portugal, through the engagement of the local community, meetings and events organization, and project participation.

The first meetup of the OWASP Lisboa Chapter - The Beginning.

Location:

OLX Portugal - Praça Duque de Saldanha nº 1 · Lisboa

Agenda:

Bots have gone phishing, but all they get is the boot

Web applications and the APIs which drive them are built with humans in mind. Exposing APIs enable interesting mashups of applications. But they also allow bots to automate access to these web applications, brute-forcing passwords, grabbing credit card numbers and gift cards; artificially inflating the price of goods and tickets; deny legitimate users service; and scraping content. Traditional approaches have focused on trying to detect legitimate browsers, known bot frameworks and user behavior but the easy availability of scriptable headless browsers are making this approach have diminishing returns. Bots are also commonly used in the context of phishing web apps. These apps are copies of the website, usually hosted in similar host names, where the user is tricked by means of phishing attacks. There, the user is convinced to enter their credentials, just like they would in the legitimate website. 2FA does not help in this context, as the user will likely volunteer this information, believing that the request comes from the legitimate website. Once in possession of the user credentials and 2FA, bots are used to automate the login into the account and steal sensitive data or commit fraud.

In this talk, we will give a brief overview of the broad goals bot-writers have when targeting your site, examples of how these have affected businesses, how traditional approaches to defending against them work and where they fail when faced with modern scripted browsers. We will then focus on phishing bots, and how to defend against them. We demonstrate a series of techniques using a combination of obfuscation and a one time token to increase the cost in time and money to a bot-writer rather than attempting to detect or block it. We will cover the challenges in creating such a solution, how to anticipate how bot-writers attempt to evade detection and how to proactively evolve the solution. A live demo will be included.

Jasvir Nagra

Jasvir Nagra is widely recognized as a thought leader in software protection. He is co-author of Surreptitious Software, the definitive textbook on software protection, and an early researcher in obfuscation, software watermarking, and fingerprinting. With more than 12 years of experience, his professional path includes companies such as Instart, Dropbox and Google - where he led the Caja project. As an advisor to Jscrambler, he is helping cybersecurity startups address key technological challenges.

OWASP API Top10

APIs are a foundational element of innovation in today’s app-driven world, exposing business logic and access to sensitive data. Because of this APIs have increasingly become a target for attackers and, unsurprisingly, the common vector between major well-known data breaches.

We’ll briefly discuss why we’ve decided to create yet another top 10 list, how it was built, and what our plans are for the next edition, but the master plan is to take most of the time to exploit a modern web application, deep diving into the top 10 API security risks as we spot them.

Paulo Silva

Since his first OWASP local event back in 2010, he has been an active community member contributing to several OWASP projects. Nowadays, he’s the OWASP Go Secure Coding Practices project co-leader and OWASP API Security Project main collaborator.

With +15 years of professional experience developing software, at some point in time decided to focus on breaking it, helping several companies and organizations to improve their security posture, either as an ethical hacker, pentester, or security researcher.

History

This page tells a bit of the OWASP Lisboa Chapter history. Actually, this chapter builds on top of a former OWASP Portugal Chapter, that existed between 2008 and 2018. During this period, the OWASP Portuguese Chapter, helped disseminate the OWASP mission in Portugal, throughout the organization and participation on multiple events, meetups and the collaboration on some projects.
