A few days ago some arrests in Slovenia were announced. People is wondering if this is really linked to the Mariposa case,as the guys behind Mariposa were from Spain, and the people arrested are from Slovenia.

Back in March, when the story went public, we talked about the Spanish guys arrested, and that they had bought the bot. Probably you realized that we didn’t mention anything about the seller of the bot. This was not because we didn’t know who was behind that, but because the FBI kindly ask us not to disclose that information, as they were chasing Iserdo. Who’s Iserdo? As far as I know, he is a Slovenian guy, the main developer of the butterfly bot and he was in touch with Netkairo, and was who sold the Mariposa bot to Netkairo.

Iserdo’s web site is down, though I took a screenshot half a year ago:


After that he changed his web (same kind of content though) but I didn’t take any screenshots. According to Netkairo, he and Ostiator gave to Iserdo a “99%” of the idea to develop the bot. This is unlikely to be true, and remember that we were having that conversation because Netkairo wanted me to hire him 🙂

On another Slovenian newspaper, there was a guy saying that the price could go up to 40,000€ I don’t know where that guy had his intel from, but that looks a bit overprized. These are the real prices:

As for the custom one, that was the one bought by Netkairo, these were the prices:
