I the news I read this:
The firm was forced to make a security disclosure on its blog and on Reddit, admitting that a development error had led to a problem with the generation of private keys. Private keys (effectively the private addresses used to hold bitcoin) were generated with a low degree of entropy, making them easy for attackers to retrieve.
Is there a detailed analysis available of what exactly happened or perhaps you could share your thoughts on this? I understand a concept of information entropy just want to know what should be done and what should be avoided to achieve a high degree of entropy.
