High-Volume, High-Rate DDoS Attacks Persist

As expected, the numbers back up the continued proliferation of both high-volume and high-rate distributed denial of service attacks – like the ones executed via NTP amplification – over the last few months. NSFOCUS, a security firm that measures DDoS traffic, released its Mid-Year Threat Report...

Google Public DNS Server Spoofed for SNMP based DDoS Attack

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 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 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...

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...

AIX 6.1 TL 8 : bind9 (IV62146)

The default configuration of ISC BIND before 9.4.1-P1, when configured as a caching name server, allows recursive queries and provides additional delegation information to arbitrary IP addresses, which allows remote attackers to cause a denial of service traffic amplification via DNS queries with...

SuSE 11.3 Security Update : ntp (SAT Patch Number 9540)

The NTP time service could have been used for remote denial of service amplification attacks. This issue can be fixed by the administrator as we described in our security advisory SUSE-SA:2014:001: http://lists.opensuse.org/opensuse-security-announce/2014-01/msg00005. html and on...

Large-Scale DDoS Attacks Continue to Spike

Although the average size of a given DDoS attack is going down, the number of attacks at the upper end of the scale is increasing, with researchers at Arbor Networks reporting more than 100 attacks of 100 Gbps in the first half of this year. In order for a DDoS attack to be effective, bad guys us...
