The maintainer of Cerberus banking trojan for Android is auctioning the entire project for a price starting at $50,000 or double the money. The price includes everything from source code to customer list along with installation guide and scripts to make components work together. For at least one year, the group behind Cerberus advertised their business and rented the malicious bot for up to $12,000 per year. According to a post from the seller on a Russian-speaking underground forum, the business is currently generating $10,000 every month.
