THE HACKER thought to have been behind the Mariposa botnet is on trial in Slovenia.

Iserdo, or Matjaž Škorjanc, 26, is accused of being the creator of the software used to build the Mariposa botnet, which was dismantled in an international cyber crime sting in 2010.

The three men that ran Mariposa were arrested in a swoop by authorities in March 2010, and their capture was coordinated between Spanish police and the FBI.

They were called opportunists, rather than sophisticated hacker criminals. They were effective though, and their link infesting keylogger trojan managed to access about 12.7 million internet addresses in 190 countries.

The FBI said that Iserdo was suspected to be the mastermind at the time of his arrest in July 2010, and it has no doubt that the botnet was a bad thing.

"In the last two years, the software used to create the Mariposa botnet was sold to hundreds of other criminals, making it one of the most notorious in the world," said FBI director Robert S. Mueller III.

"These cyber intrusions, thefts, and frauds undermine the integrity of the Internet and the businesses that rely on it; they also threaten the privacy and pocketbooks of all who use the Internet."

Mariposa style botnets were built using Škorjanc's "Butterfly Bot" code, according to the Slovenian authorities, and it was sold to cyber criminals worldwide. Mariposa, the Spanish version of the botnet, was the largest and the most notorious.

Škorjanc is also accused of tailoring his software to customer requests and selling plugins to boost its features. µ
