My Journey into Android Security Research My path to becoming an Android security researcher was not a conventional one. I have been working as a security researcher for the past two years, focusing primarily on Android application defense, attack vectors, and vulnerability research. My role at Cyfinoid Private Limited involves identifying security flaws, developing training modules, and creating challenge applications to help developers and hackers understand Android security. One of the defining moments in my journey was discovering and reporting a critical business logic bug on the Yubico website, which led to recognition and a reward.

Halborn discovered a massive #ZeroDay vulnerability code-named Rab13s impacting Dogecoin and 280+ networks, including Litecoin and Zcash, putting over $25 Billion of digital assets at risk. To understand the zero-day vulnerability Rab13s, we need to go through some basic concepts. So I would like to explain blockchain and its key characteristics. Blockchain is a data structure used to represent a cryptocurrency. Stores data in a way that allows multiple parties to access it reliably without having to trust one another.

I have been an active participant in the crypto space since August 2017 and I consider myself to be pretty tech-savvy. However, I have been shocked every time I’ve fallen victim to a phishing scam. Unfortunately, it has happened to me three times now. The first time I was phished, I had just opened a new wallet and gave away my seed phrase to a scam website. I was new to the space and didn’t know any better, so I thought it was okay.
