JObfuscator

JObfuscator – wielopoziomowa obfuskacja liczb

przez

Aktywne prace nad moim obfuskatorem dla Javy, czyli JObfuscatorem doprowadziły do poprawienia drobnych błędów i rozszerzenia funkcjonalności.

Historia silnika

v1.03 – 31.07.2021

  • Niektóre wartości typu integer nie były poprawnie ekstrahowane dla strategii obfuskacyjnej polegającej na przenoszeniu wartości liczbowych do tablic
  • Wielopoziomowa obfuskacja wyekstrahowanych wartości liczbowych do tablic (do losowej liczby tablic, o typach double i integer)

Jak prezentują się wprowadzone zmiany do silnika obfuskatora?

Obufuskacja wartości liczbowych w Javie

przez

Mój JObfuscator zyskał nową funkcjonalność, aby ochronić się przed wbudowanym deobfuscatorem w popularnym narzędziu do dekompilacji Javy – JEB.

https://www.pelock.com/pl/jobfuscator/

Wprowadzona zmiana do silnika w wersji v1.02:

  • Strategia obfuskacyjna polegajaca na przenoszeniu wartości liczbowych do tablic, zamiast zapisywanych tam wartości integer, zapisuje je jako typ double, aby zapobiec deobfuskacji przez popularne dekompilatory Javy np. double[] var_2597 = new double[]{13.898355719807563D, 65535.73657403742D, ... };.

A wyniki poniżej:
