Reversing An Obfuscated Java Malware

Some time in the recent past, I stumbled upon a news on The Intercept, about a malware being used against some Argentine prosecutor, who was found dead under uncanny circumstances (Fig. 1 & 2). Interested, I decided to have a look at the malware. On further analysis, it revealed that it was a java based malware. Since java reversing is somewhat less documented, I decided to shed some light in this field, and the result of that is this document.
