Botnet

+ - Sality Botnet Mapped Entire IPv4 Address Space without Raising Alarms->

Submitted by hypnosec
hypnosec (2231454) writes "A little known botnet – Sality, in a search for vulnerable VoIP (Voice over IP) servers has probably managed to map the entire IPv4 address space without raising alarms it has been claimed. Researchers over at University of California and the University of Napoli in Italy have revealed in their research paper [PDF] that the Sality botnet, scans for vulnerable VoIP targets and that too using a technique called “reverse-byte order scanning.” In this particular method of scanning the choice of IP addresses progresses in reverse-byte order increments which not only results in a low number of packets per day, out of all the IP addresses, which the researchers monitored using UCSD Network Telescope, a million IPs actually dropped out of the scanning activity after transmitting only one probe."
