As the Regional State Prosecutor for the General-Criminal Department he directs pre-trial criminal proceedings and represent the prosecution in criminal proceedings against offenders in the area of general-criminal and economic crimes, as well as for criminal offences related to computer crime, such as: intrusions in information systems, computer forgery, computer fraud, money laundering deriving from related offences, etc.
During the last three years, together with his colleague the Regional State Prosecutor Izidor Rojs, he directed the pre-trial criminal proceedings against the author of one of the most dangerous malicious codes called ButterFly Bot (BF bot) and ButterFly Flooder (BFF) which infected several million information systems worldwide and which was used by Spanish suspects to create one of the largest bot networks called “Mariposa”.
