Out of Character Use of Punycode and Homoglyph Attacks to Obfuscate URLs for Phishing

Learn about advanced phishing techniques using punycode and homoglyph attacks in this 38-minute conference talk from AIDE 2012. Explore classic URL obfuscation methods, homographs, and the challenges posed by ASCII-based DNS. Discover likely sources for homoglyphs, examine a homoglyph attack generator demo, and understand browser and registrar protections. Investigate canonicalization errors, name spoofing, right-to-left text manipulation, and file name vulnerabilities. Gain insights into useful resources and references for further study on URL obfuscation and phishing prevention.
