Ecuador has quite strict computer crime laws. E.g. distribution of hacking tools is illegal.
The law he is being charged with violating reads: "Diseñe, desarrolle, programe, adquiera, envíe, introduzca, ejecute, venda o distribuya de cualquier manera, dispositivos o programas informáticos maliciosos o programas destinados a causar los efectos señalados en el primer inciso de este artículo."
which google translates as: Design, develop, program, acquire, send, introduce, execute, sell or distribute any malicious means, devices or programs or programs intended to cause effects indicated in the first paragraph of this article.
Laws that criminalize creation/distribution of "hacking tools" are dangerous and scary because there's really no bright line as to what constitutes a hacking tool; e.g., it's even possible that Ola's work on JOpenSSL or OTRv4 could be construed as a "hacking tool" under this law :(
A good if unfortunate reminder to anyone who works in computer security to check local laws before traveling and especially before emigrating.
The article body says they apprehended a lot of electronic equipment on his house, and many credit cards. It also says he travels a lot. I'm not getting into any specifics because the article doesn't get into them either...
Also, it says nothing about what he actually hacked.
