vis0r

Programming Linux Anti-Reversing Techniques es un libro gratuito de Jacob Baines que muestra al lector cómo programar y analizar las técnicas más conocidas de anti-reversing en Linux. El libro muestra cómo un reverser analiza un binario con herramientas como IDA, Radare2, GDB, readelf y más. El código es presentado al lector listo para que pueda compilarlo y analizarlo por sí mismo.
