DoS and DDoS Attack Threat Advisory – Drive – Dirt Jumper

Prolexic Security Engineering & Response Team (PLXsert) Threat Advisories

New! NTP Amplification DDoS Toolkit Threat Advisory

Fueled by the availability of new DDoS toolkits that make it simple from malicious actors to generate high-bandwidth, high-volume DDoS attacks against online targets, the NTP amplification attack method has surged in popularity.

With only a handful of vulnerable NTP servers, the current batch of NTP amplification attack toolkits enable malicious actors to launch 100 Gbps attacks – or larger. The most recent toolkit uses an NTP server’s own list of recent server connections – as many as 600 IP addresses – as the payload to create malicious traffic at the target site.

Other Recent Threat Advisories:

  • Domain Name System (DNS) Flooder
    Malicious actors are purchasing, setting up and using their own DNS servers in reflection attacks, avoiding the need to source vulnerable DNS servers on the Internet. This advisory includes a sample payload, analysis, source code, Snort rule, ACL mitigation and two case studies.

  • Drive, a Dirt Jumper variant
    Finance and e-Commerce firms have been targeted with the Drive DDoS toolkit as a planned distraction by criminals engaging in identity theft and fraud of customer accounts. This threat advisory includes an analysis of payloads, capabilities, and IDS signatures for DDoS detection.

  • Itsoknoproblembro
    This threat advisory includes profiles of 11 different attack signatures, with detailed SNORT rules for DDoS mitigation; detection rules to identify infected web servers (bRobots), and a free log analysis tool (BroLog.py) that can be used to pinpoint which scripts were accessed, by what IP address, and for what DDoS targets.

  • Dirt Jumper Vulnerability Disclosure Report
    The Dirt Jumper family of DDoS Toolkits is considered one of the most popular attack tools on the market today. This vulnerability report exposes key weaknesses in the command and control (C&C) architecture that could neutralize would-be attackers.

  • Pandora
    This Russian-origin toolkit offers five DDoS attack modes and appears to be authored by the same individual responsible for the popular and destructive Dirt Jumper family of tools.

  • HULK (HTTP Unbearable Load King)
    This script takes advantage of common weaknesses with out-of-the-box web server functionality by launching 500 threads, which each spawn an additional 500 threads at the target web server.

  • Booter Shell Scripts
    These sophisticated, easy-to-use DDoS attack scripts make it possible to bring down web servers without vast networks of infected zombie computers.

  • High Orbit Ion Cannon (HOIC)
    This stealth DDoS attack tool targets up to 256 URLs simultaneously and randomizes attack signatures.

  • Dirt Jumper
