  • Debug Register Rootkits a Study of Malicious Use of the IA-32 Debug Registers
    DV1446 – Kandidatarbete i Datavetenskap Bachelor Thesis in Computer Science – Security Engineering Debug register rootkits A study of malicious use of the IA-32 debug registers May 2012 Authors: Emil Persson, Joel Mattsson Supervisor: Ewa Osekowska School of Computing Blekinge Institute of Technology This thesis is submitted to the School of Computing at Blekinge Institute of Technology in partial fulfillment of the requirements for the degree of Bachelor of Science in Computer Science. The thesis is equivalent to 20 weeks of half time studies. Contact Information: Authors: Emil Persson E-mail: [email protected] Joel Mattsson E-mail: [email protected] University advisor: Ewa Osekowska E-mail: [email protected] School of Computing Blekinge Institute of Technology Internet : www.bth.se/com SE–371 79 Karlskrona Phone : +46 455 38 50 00 Sweden Fax : +46 455 38 50 57 Abstract The debug register rootkit is a special type of rootkit that has existed for over a decade, and is told to be undetectable by any scanning tools. It exploits the debug registers in Intel’s IA-32 processor architecture. This paper investigates the debug register rootkit to find out why it is considered a threat, and which malware removal tools have implemented detection algorithms against this threat. By implementing and running a debug register rootkit against the most popular Linux tools, new conclusions about the protection of the Linux system can be reached. Recently, debug register rootkits were found on Windows as well. This project intends to bring knowledge about the problem and investigate if there are any threats.

As 5.0 is not meant for production, I will at least wait for 5.1 to be out for a while before I approach locking down FreeBSD 5.x. This document is intended to be a working checklist of security settings implemented on FreeBSD servers version 4.8-RELEASE. There are a number of well-written and often brilliant documents providing overviews, how-to's and faqs on FreeBSD security for the practical systems administrator, but there is no to-the-point, checklist that can be a tool for each time a server is built.

  • Métodos Para Detecção Local De Rootkits E Módulos De Kernel Maliciosos Em Sistemas Unix
    MÉTODOS PARA DETECÇÃO LOCAL DE ROOTKITS E MÓDULOS DE KERNEL MALICIOSOS EM SISTEMAS UNIX Nelson Murilo Klaus Steding-Jessen Pangéia Informática NIC BR Security Office SRTS 701, 70 cj E, sala 304 Rua Hum, 45 Caixa Postal 6146 70340-902 Brasília-DF 13083-970 Campinas-SP [email protected] [email protected] RESUMO Rootkits são ferramentas utilizadas com freqüência por invasores para ocultar sua presença em máquinas comprometidas, fazendo parte inclusive de alguns Worms e ferramentas de DDoS. Uma invasão pode passar meses sem ser descoberta graças a essas ferramentas. Além das versões tradicionais, rootkits vem sendo imple- mentados também sob a forma de módulos de kernel (LKMs), dificultando a sua detecção. Este artigo descreve o funcionamento desses dois tipos de rootkit, alguns métodos para sua detecção em sistemas Unix e uma ferramenta de código aberto, implementada pelos autores, para detecção automatizada de rootkits. ABSTRACT Rootkits are a very popular technique among intruders to hide themselves in compromised machines. Some rootkits are also used by Worms and DDoS tools. An intrusion can remain undetected for months when such a tool is used by an attacker. Rootkits are also being implemented as Loadable Kernel Modules (LKMs), making them much harder to detect. This paper describes the traditional as well as the LKM-based rootkit and presents some rootkit detection methods for Unix machines. This paper also presents an open source tool, developed by the authors, to detect rootkits. 1 INTRODUÇÃO evolução dos rootkits, seguido da descrição dos com- ponentes e funcionamento dos rootkits tradicionais e Com a popularização de ferramentas de ataque au- também dos implementados sob a forma de LKMs.

  • Malware Forensics Field Guide for Linux Systems: Digital Forensics
    Chapter 3 Postmortem Forensics Discovering and Extracting Malware and Associated Artifacts from Linux Systems Solutions in this Chapter • Linux Forensic Analysis Overview • Malware Discovery and Extraction from a Linux System • Examine Linux File System • Examine Linux Configuration Files • Keyword Searching • Forensic Reconstruction of Compromised Linux Systems • Advanced Malware Discovery and Extraction from a Linux System INTRODUCTION If live system analysis can be considered surgery, forensic examination of Linux systems can be considered an autopsy of a computer impacted by mal- ware. Trace evidence relating to a particular piece of malware may be found in various locations on the hard drive of a compromised host, including files, configuration entries, records in system logs, and associated date stamps. Foren- sic examination of such trace evidence on a Linux system is an important part of analyzing malicious code, providing context and additional information that help us address important questions about a malware incident, including how malware was placed on the system, what it did, and what remote systems were involved. This chapter provides a repeatable approach to conducting forensic examinations in malware incidents, increasing the consistency across mul- tiple computers, and enabling others to evaluate the process and results. Employing this approach, with a measure of critical thinking on the part of a digital investigator, can uncover information necessary to discover how malware was placed on the system (a.k.a. the intrusion vector), to determine Malware Forensics Field Guide for Linux Systems. http://dx.doi.org/10.1016/B978-1-59749-470-0.00003-6 Copyright © 2014 Elsevier Inc.

Appendix . 37 1. Introduction The motivation behind this paper is to explore using the tool Lynis that comes with Kali Linux. What is this tool: "Lynis is an open source security auditing tool. Its main goal is to audit and harden Unix and Linux based systems. It scans the system by performing many security control checks. Examples include searching for installed software and determine possible configuration flaws. Many tests are part of common security guidelines and standards, with on top additional security tests. After the scan a report will be displayed with all discovered findings. To provide you with initial guidance, a link is shared to the related Lynis control." source: Kali Linux "Since Lynis is flexible, it is used for several different purposes. Typical use cases for Lynis include: - Security auditing - Compliance testing (e.g. PCI, HIPAA, SOx) - Penetration testing - Vulnerability detection - System hardening " source: Lynis What does Lynus run on? "Lynis runs on almost all UNIX-based systems and versions, including: - AIX - FreeBSD - HP-UX - Linux - macOS - NetBSD - NixOS - OpenBSD - Solaris - and others It even runs on systems like the Raspberry Pi, IoT devices, and QNAP storage devices." source: Lynis "Lynis scanning is modular and opportunistic.
