The Insider ( github.com/Ch0pin/uncrack…) is not for quitters — and Sabr0x clearly isn’t one 😎. Well done on solving this challenge! 👏

While vendors dismiss the risk of vulnerabilities that require a third-party app to exploit, considering such scenarios unlikely to occur in practice Google bans Google Bans 158,000 Malicious Android App Developer Accounts in 2024 thehackernews.com/2025/01/google…

Want to add your challenge to github.com/Ch0pin/uncrack… ? Go ahead and open a PR! Just make sure it showcases a real vulnerability — ideally a whole class. Current ones focus on interesting behaviors like bypasses. Would love to include yours! #AndroidSecurity

Kudos to Wixter_07 for solving ‘Four’ and ‘Secure Browser’! Friendly reminder :) Looks like ‘Insider’ is still holding strong with only 11 solves so far github.com/Ch0pin/uncrack…

Here are some thought-provoking unanswered questions🤔: - Is free will an illusion? - Can morality be objectively defined without culture or religion ? ...and the greatest of all..... - Why do people willingly deobfuscate Java code?

Excited to share that my latest research has been accepted at NULLCON Berlin! It’s a follow-up to my previous work presented at Black Hat Europe — this time, we’re diving even deeper. See you in September in Berlin! 🇩🇪

Judging by how most Android developers verify URLs, a solid android[.net.Uri bypass could be the next big thing in app security 😬
