    Published July 9, 2014

    Blackshades RAT crimeware is used for identity theft and blackmail. It allows malicious actors to spy on users by monitoring video and audio, keylogging, harvesting banking and website access credentials, and controlling the victim machine to hijack files and to launch executables.

  • Zeus Crimeware

    Published June 10, 2014

    The Zeus toolkit is used in many types of cybercrime, including customized attacks to target Fortune 500 enterprises. Attackers leverage the resources of infected devices and extract sensitive information for identity theft and fraud. Includes mitigation details.

  • SNMP Reflector

    Published May 22, 2014

    Simple Network Management Protocol (SNMP) reflection tools are used by malicious actors to harness devices such as printers, switches, firewalls and routers for use in DDoS attacks. Network administrators need to take the remediation steps described.

  • Storm Network Stress Tester

    Published April 29, 2014

    The Storm crimeware kit infects Windows XP (and higher) systems for malicious uses and enables file uploads and downloads and the launching of executables, including four DDoS attacks. Remote access lets malicious actors use a PC for malicious activity, such as the infection of other devices.

  • NTP Amplification

    Published March 12, 2014

    With only a handful of vulnerable NTP servers, NTP amplification attack toolkits enable malicious actors to launch 100 Gbps DDoS attacks and larger.

  • Domain Name System (DNS) Flooder

    Published February 11, 2014

    Malicious actors are purchasing, setting up and using their own DNS servers in reflection DDoS attacks, avoiding the need to source vulnerable DNS servers on the Internet. Includes a sample payload, analysis, source code, Snort rule, ACL mitigation and two case studies.

  • Drive, a Dirt Jumper variant

    Published August 28, 2013

    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. Includes an analysis of payloads, capabilities, and IDS signatures for DDoS detection.

  • Itsoknoproblembro

    Published January 3, 2013

    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

    Published August 14, 2012

    The Dirt Jumper family of DDoS toolkits are popular. This vulnerability report exposes key weaknesses in the command and control (C&C) architecture that could neutralize would-be attackers.

  • Pandora

    Published August 14, 2012

    This toolkit offers five DDoS attack modes and appears to be authored by the same individual responsible for the Dirt Jumper family of tools.

  • SNMP Amp (SAD)

    Published March 2012
