Arbor: DDoS Attacks Getting Bigger as Reflection Increases

Reflected distributed denial of service DDoS attacks continue to increase, particularly among large scale DDoS events, but it’s a relatively new type of amplification attack which exploits the Simple Service Directory Protocol SSDP that has emerged in a new Arbor Networks report. Data from the...

SNMP DDoS Attack Spoofs Google DNS Server

Update: The SANS Internet Storm Center this afternoon reported SNMP scans spoofed from Google’s public recursive DNS server seeking to overwhelm vulnerable routers and other devices that support the protocol with DDoS traffic. “The traffic is spoofed, and claims to come from Google’s DNS server...

NTP Mode 6 REQ_NONCE DRDoS Scanner

This module identifies NTP servers which permit mode 6 REQNONCE requests that can be used to conduct DRDoS attacks. In some configurations, NTP servers will respond to REQNONCE requests with a response larger than the request, allowing remote attackers to cause a distributed, reflected denial of...

NTP Mode 7 PEER_LIST_SUM DoS Scanner

This module identifies NTP servers which permit "PEERLISTSUM" queries and return responses that are larger in size or greater in quantity than the request, allowing remote attackers to cause a distributed, reflected denial of service aka, "DRDoS" or traffic amplification via spoofed requests...

NTP Mode 7 PEER_LIST DoS Scanner

This module identifies NTP servers which permit "PEERLIST" queries and return responses that are larger in size or greater in quantity than the request, allowing remote attackers to cause a distributed, reflected denial of service aka, "DRDoS" or traffic amplification via spoofed requests. Module...

NTP Mode 7 GET_RESTRICT DRDoS Scanner

This module identifies NTP servers which permit "reslist" queries and obtains the list of restrictions placed on various network interfaces, networks or hosts. The reslist feature allows remote attackers to cause a distributed, reflected denial of service aka, "DRDoS" or traffic amplification via...

Dramatic Drop in Vulnerable NTP Servers Used in DDoS Attacks

While patching of webservers vulnerable to the Heartbleed OpenSSL bug may have stalled, the same cannot be said about repairs to NTP servers that could be leveraged in devastating amplification attacks. A spate of distributed denial-of-service attacks DDoS tore through companies in January and...

400 Gbps NTP Amplification DDoS Attack Alarmingly Simple

The largest distributed denial of service attack on public record was reported this week, and with it came many alarming numbers, not only in the volume of traffic generated 400 Gbps at its peak, but in the number of Network Time Protocol servers involved 4,592 on 1,298 networks as well as the...

broadcast-dhcp6-discover NSE Script

Sends a DHCPv6 request Solicit to the DHCPv6 multicast address, parses the response, then extracts and prints the address along with any options returned by the server. The script requires Nmap to be run in privileged mode as it binds the socket to a privileged port udp/546. See also:...

NTP Monitor List Scanner

This module identifies NTP servers which permit "monlist" queries and obtains the recent clients list. The monlist feature allows remote attackers to cause a denial of service traffic amplification via spoofed requests. The more clients there are in the list, the greater the amplification. This...
