If java.class files are very secured and no one can see your souce code, how then is it that people hack programms and systems??

Question

Help me understand...is there a way someone can get access to your programm and alter it without having the source code??...or how exactly do hackings happen..thanks for any replies...decided never to pretend i know..

Answer 1

yes it's still possible to see your code, there are some reverse engineering tools that one can use to do so, the best practice is to apply code obscurification and encryption techniques to add extra security levels. However, keep in mind that your code resides on their device...so eventually no code is 100% secured.

Answer 2

yes I know N00B ...I suggested that as a security measure...if nothing, it's still better to do that than leaving everything as original code so when someone reverse engineers your class, they'd have to do some serious work before knowing what you actually wrote

Answer 3

George Samanlian Code obfuscation is security by obscurity: https://en.wikipedia.org/wiki/Security_through_obscurity
