Also, those messages contained attachments that when viewed infected computers as well as dispatched the same e-cards to every other e-mail id listed on the contact lists of those PCs'. This way more systems were infected that were added to the expanding botnet. Incidentally, the security company found that Buzus' chief payload was the infamous botnet namely Hiloti.

Stated Project Manager Derek Manky in-charge of Fortinet's Cyber Security and Threat Research division that cyber-criminals preferred Hiloti that was spread via lot of different botnets as the malware introduced a 'pay-per-install' associate module through which long-standing botnet distributors earned certain fee whenever Hiloti was inserted inside a fresh computer.
