Google Public DNS Server Spoofed for SNMP based DDoS Attack

Google Public DNS Server Spoofed for SNMP based DDoS Attack

Sep 16, 2014
The Distributed Denial of Service ( DDoS ) attack is becoming more sophisticated and complex, and, according to security experts , the next DDoS vector to be concerned about is SNMP (Simple Network Management Protocol) amplification attacks. Yesterday afternoon, the SANS Internet Storm Center reported SNMP scans spoofed from Google's public recursive DNS server searching for vulnerable routers and other devices that support the protocol with DDoS traffic and are opened to the public Internet. " We are receiving some reports about SNMP scans that claim to originate from (Google's public recursive DNS server), " wrote Johannes Ullrich, dean of research of the SANS Technology Institute and head of the Internet Storm Center. " This is likely part of an attempt to launch a DDoS against Google by using SNMP as an amplifier/reflector. " Simple Network Management Protocol (SNMP) is a UDP-based protocol designed to allow the monitoring of network-

SNMP Reflection DDoS Attacks on the Rise

The DDoS techniques have massively increased with the attackers becoming more skillful at working around the network security. A massive 300Gbps DDoS attack launched against Spamhaus website almost broke the Internet a year ago and also earlier this year, hackers have succeeded in reaching new heights of the massive DDoS attack targeting content-delivery and anti-DDoS protection firm CloudFlare, reaching more than 400Gbps at its peak of traffic. Akamai's Prolexic Security Engineering and Response Team (PLXsert) issued a threat advisory on Thursday reporting a significant surge in DDoS attacks last month abusing the Simple Network Management Protocol (SNMP) interface in network devices. Simple Network Management Protocol (SNMP) is a UDP-based protocol which is commonly known and often used to manage network devices. SNMP is typically used in devices such as printers, routers and firewalls that can be found in the home and enterprise environments as well. Just as D
