Waledac bot profligacy

Share this article:
Waledac-infected computers are, on average, capable of sending 6,548 spam emails per hour, or two emails per second, according to security vendor ESET. Over the course of several one-hour periods, a Waledac-infected computer in the company's lab delivered between 5,610 to 7,148 spam emails. If 20,000 computers are infected with Waledac, as researchers estimate, then the botnet is capable of sending three billion emails per day, if all infected computers were working to full capacity. — AM
