This is the second of two articles that describe how to use the Defensics SDK in fuzzing Bitcoin. In the previous article, you saw how to set up a test bed for bitcoind. We created two containers, alice and bob, and were able to set up communication between the two bitcoind instances. In this article, you’ll learn […]

This is the first of two articles that describe how to use the Defensics SDK to fuzz Bitcoin software. Specifically, you will learn how to model one of the Bitcoin protocol messages and use the Defensics SDK to perform fuzzing on the bitcoind process. This is an advanced technical tutorial, and you will need some background […]

The habit of breaking things When I was a child, I liked to break things to see how they were built. When I was older, I didn’t grow out of this habit. In fact, I joined a company with like-minded individuals. Now we don’t break things just for the sake of breaking them; we break […]

Written in coordination with Chris Clark, Defensics product manager Over the last year, we’ve noticed a rise in Defensics myths. Admittedly, this doesn’t surprise me. Myths abound in technology markets, where facts and figures often stand in contrast to conventional wisdom, and the fuzz testing market is a particularly challenging one to navigate. I suspect […]

Only when security is treated with the same importance as quality can your software’s integrity drive a proactive strategy rather than a reactive response. In addition to ensuring software quality, development teams are under increasing pressure to address software security concerns. The high-profile data breaches that continuously arise are raising awareness of security issues. Because […]

The definition of responsible vulnerability disclosure varies based on who you ask. Tech goliath Microsoft has openly disagreed with Google on this very topic, as outlined by The Verge. In the vulnerability management industry, discretion is key. Because we’re continuously handling vulnerabilities that can be used maliciously by black hats, there are widespread implications and […]

Last October, a distributed denial-of-service (DDoS) attack by the name of Mirai brought popular websites such as Netflix, Spotify, Twitter, SoundCloud, and more to their knees. Now, nearly a year later, Mirai is a distant memory, but we may not have seen the worst of Internet of Things (IoT) DDoS attacks. Security researchers at cyber […]

At Synopsys, our R&D teams routinely organize internal hackathons to verify the Synopsys Software Integrity Portfolio’s performance in real-world environments. During one hackthon, focused on open source software, Tuomas Haanpää, from the Synopsys Fuzz Testing (Defensics) R&D group, ran our NFSv3 test suite against the Linux kernel and found several interesting errors. Initial analysis found that anomalized […]

In a new report, Synopsys examines new insights into areas of software development where further testing remains. By analyzing over 4.8 billion protocol-based tests, the Synopsys State of Fuzzing 2017 report qualifies the relative levels of maturity in terms of quality and security across more than 250 protocols found in industry verticals such as industrial […]
