We are celebrating our fourth lecture on free software development. In partnership with IMEsec, we are pleased to announce the lecture given by Seth Schoen from the Electronic Frontier Foundation (EFF).

This time we will be privileged to have EFF’s senior staff technologist Seth Schoen talking about “Reproducible Software Builds, Supply-Chain Security, and Risks for Source-Binary Correspondence”.

When Tuesday, June 11, 2019, at 2pm
Where IME-USP, CCSL, CCSL Auditorium (downstairs)

About the speaker

Schoen works for the Electronic Frontier Foundation as a senior staff technologist. He was a co-author of “Lest We Remember: Cold Boot Attacks on Encryption Keys”, helped create the LNX-BBC live CD and the Let’s Encrypt certificate authority, and has presented at conferences and meetings in more than ten countries. He has testified before several courts and regulatory agencies in the United States and trained government officials and journalists in Latin America about privacy and information security topics.

About the lecture

Seth is reprising and updating a topic about which he presented at several conferences a few years ago. As the issue of supply-chain security for IT products is constantly back in the news, Seth will consider the problem of how we know that the binary code we create or receive from others matches the source code from which it was supposedly created. He will demonstrate an attack where a compromised workstation produces malicious binaries from non-malicious source code. This also touches on an enormous range of supply-chain security concerns, including those related to the integrity of software updates, and on valuable work on reproducible compilation being done by the Debian Project, Tor Project, and Mozilla, among others.

Note: This talk will be presented in Portuguese; audience questions are welcomed in English, Portuguese, or Spanish.
