 vel 1 Hall 3 903 (Main Track 5) and DCTV-5 - [1]Map\n\n   Description:\n\n
    North Korea operates the world’s most extreme digital environment.\n 
   Its custom Android OS enforces an "allowlist" ecosystem where media\n   
 and apps require state-issued cryptographic signatures to run\, while\n   
 background daemons capture secret screenshots to log "illegal"\n   activit
 y. In this restrictive environment\, the stakes for accessing\n   outside 
 information are measured in prison sentences and public\n   executions.\n\
 n   Yet\, the hackers are active. This talk deconstructs the regime's\n   
 information control systems—from signature-verification logic to\n   Tra
 ceViewer forensics—and reveals how a network of defectors and\n   techno
 logists is fighting back. We will demo Pigeon\, a working\n   SELFSIGN spo
 of that bypasses handset verification\, and discuss eMMC\n   chip-off tech
 niques used to study device internals\, and look at\n   Windows data conce
 alment methods used by defectors.\n\n   This isn't just a technology brief
 ing\; it’s an offensive security\n   call for support. I will map out a 
 unique and intriguing engineering\n   backlog which includes media obfusca
 tion tools\, Android internals\n   research\, binary analysis\, anti-foren
 sics\, and hardware hacking. I\n   will show how these skills directly tra
 nslate into\n   freedom-of-information tool development. Built and validat
 ed through\n   iterative testing with defectors\, some of these technologi
 es are\n   operational already today.\n\n     * Korean Ministry of Unifica

 's Hidden Revolution\n\n   SpeakerBio:  JDT\, Liberty in North Korea\n\n  
  JDT brings over a decade of cybersecurity expertise to his role as\n   Ch
 ief Technology Officer at LiNK. Before joining the organization\, he\n   s
 erved as the lead specialist for the U.S. Department of Homeland\n   Secur
 ity’s HQ Threat Hunt team\, following ten years spent in\n   incident re
 sponse and red-teaming across the banking\, retail\, and tech\n   sectors.
 \n\n   After volunteering for the North Korean human rights movement in 20
 19\,\n   JDT stepped into the CTO role in 2025 to spearhead the developmen
 t of\n   tools designed to pierce the world’s most restrictive informati
 on\n   environment. By repurposing his deep understanding of adversary\n  
  tradecraft\, he develops unconventional technologies that empower North\n
    Koreans to access outside information safely and bypass state\n   surve
 illance.\n\n   '\n\n   1. #LVCCW_Level1_Hall3\n\n\n
