This document provides a summary of strategies for preventing distributed denial of service (DDoS) attacks. It discusses both preventive defenses, such as securing systems against infection by patching vulnerabilities and monitoring for anomalous behavior, and reactive defenses, such as filtering spoofed traffic and increasing available resources. The key challenges are that preventive measures cannot always block all attacks and reactive strategies like filtering large traffic volumes can be expensive to implement effectively. Overall, the document outlines an approach to DDoS prevention through reducing infection risks and reacting to detected attacks.
Infoblox White Paper - Top Five DNS Security Attack Risks and How to Avoid ThemJennifer Nichols
This document discusses DNS security risks and how to better secure DNS infrastructure. It outlines five common DNS attack types, including TCP SYN floods, UDP floods, spoofed source address attacks, cache poisoning attacks, and man-in-the-middle attacks. It argues that general-purpose computers running operating systems like UNIX are not well-suited for DNS servers due to the complexity of securing the OS, difficulty of regularly updating both the OS and DNS software, and risk of compromise via user logins. Instead, it advocates for purpose-built appliances that are easier to secure and update to better prevent DNS attacks.
This document discusses advanced persistent threats (APTs) and strategies for cyber defense. It describes APTs as advanced, persistent, and threatening adversaries that are formally tasked to accomplish missions. The document outlines the lifecycle of APT attacks, including establishing backdoors in networks, maintaining long-term control, and exfiltrating data using encryption. It provides examples of APT groups and tools they use, such as exploiting vulnerabilities to escalate privileges and dump cached credentials from Windows networks. The overall summary is that APTs are dangerous, organized adversaries requiring persistent cyber defense strategies.

This document summarizes three papers related to data compression and network security. The first paper studies how improper implementation of data decompression in network services can enable denial-of-service attacks. It identifies 12 categories of flaws and evaluates popular services finding 10 vulnerabilities. The second paper proposes the Bohatei system to improve defense against DDoS attacks using SDN/NFV. It presents a hierarchical decomposition approach and proactive tag-based steering. The third paper examines data compression as a source of security issues, studying past attacks like zip bombs and analyzing pitfalls in design, implementation, specification and configuration of compression in network services.
This presentation will introduce the Lockheed Martin Cyber Kill Chain and MITRE ATT&CK frameworks. By working through 4 different practical scenarios in a fictional company https://sensenet-library.com, the attendees will learn how they can use those frameworks to measure their security response in today's diverse security threat landscape. We'll go through categorising security controls, responding to a vulnerability report, assessing a threat intel report and decide on future of the company's toolset where you will be able to answer a question if you should continue investing in a tool or should you buy a new one.
2016 state of the internet threat advisory dnssec ddos amplification attacksAndrey Apuhtin
The document discusses DNSSEC amplification DDoS attacks that have been observed over the past quarters. It notes that attackers have been leveraging a specific DNSSEC-configured .gov domain to launch over 400 attacks due to the large response size it provides. The domain has been used in attacks against customers in multiple industries. It then provides technical details on how DNSSEC works and how attackers are exploiting it to amplify DDoS attacks through DNS reflection techniques.

It outlines best practices for organizational security, preparing, installing, and configuring Windows Server, as well as user account, network, registry, and general security settings. It also addresses audit policy, software security, and finalization steps like imaging servers. Implementing the guidelines can help reduce security vulnerabilities and the risk of attacks compromising critical systems and data.
This document is a presentation on hacking techniques given by Martin G. Nystrom from Cisco Systems. It outlines methods for footprinting targets on the internet, hacking Windows systems, hacking Unix/Linux systems, and hacking networks. For Windows, it discusses scanning, enumeration, penetration, privilege escalation, pillaging systems, gaining interactive access, and expanding influence. For Unix/Linux, it outlines discovering the landscape, enumerating systems, attacking remotely and locally, and gaining privileges beyond root. It also discusses vulnerabilities in networks and dealing with firewalls.
07182013 Hacking Appliances: Ironic exploits in security productsNCC Group
The document discusses security vulnerabilities found in various security appliance products. It describes easy password attacks, cross-site scripting vulnerabilities with session hijacking, lack of account lockouts, and other issues found across email/web filtering, firewall, and remote access appliances from vendors like Barracuda, Symantec, Trend Micro, Sophos, Citrix, and others. Many appliances were found to have command injection flaws allowing root access. Vendors' responses to reported vulnerabilities varied, with some issues getting addressed within months while others saw no fixes. The author advocates defense-in-depth practices and keeping appliances updated with vendor patches.
This document discusses program security for Android apps. It begins with an introduction of the speaker and covers topics like Android architecture, app threat models, app components like activities and intents, data storage security, cryptography, injection attacks, and reverse engineering defenses. The document provides examples of real security issues from apps like LinkedIn and Pandora and offers tips to defend against various threats like improper data handling, insecure communication, and client-side injection.

The document discusses various information security threats and countermeasures across infrastructure, systems, databases, and networks. It describes threats like viruses, worms, Trojans, SQL injection, and denial of service attacks. It also explains associated countermeasures like firewalls, intrusion detection, input validation, log monitoring, and defense in depth.
This document summarizes three papers presented at an S&P 2012 security conference session on system security. The first paper proposes a framework to eliminate backdoors from response-computable authentication systems. The second paper discusses replacing the standard program loader with a secure loader to prevent attacks on software-based fault isolation. The third paper presents a technique called ReDebug for finding unpatched code clones in entire OS distributions.
Attackers can quietly move laterally within networks by first gaining initial access, such as through phishing, then using tools and techniques to discover and access other systems on the network. This includes using powershell to run code without touching disks, download payloads from remote systems, and inject shellcode. It also involves using tools like mimikatz to dump credentials and move access from one system to another to gain higher privileges. The goal is often to compromise domain controllers to access domain admin credentials and gain full control.
Time-based DDoS Detection and Mitigation for SDN ControllerLippo Group Digital
This document proposes a method to detect and mitigate distributed denial of service (DDoS) attacks on software defined networking (SDN) controllers using time-based characteristics. The method considers not only the malicious packet destination but also the time needed to achieve high traffic rates and periodic attack patterns. The proposed solution architecture monitors packet rates over time windows to detect abnormal traffic increases. Future work includes optimizing detection thresholds, deeper analysis of DDoS attack time patterns, and evaluation of the method's performance in a simulation.
The document discusses automatic malware clustering and detection. It covers the current state of antivirus classification, which relies primarily on signature-based methods. Automatic malware clustering aims to recognize known malware to filter it out and focus on new threats. The clustering process typically involves malware analysis, feature extraction, and clustering algorithms. Inconsistent labeling of malware families by different antivirus vendors poses challenges. The document advocates improving classification by describing the full malware lifecycle.

NCC Group 44Con Workshop: How to assess and secure ios appsNCC Group
This document provides an overview of assessing and securing iOS apps. It discusses setting up a testing environment by jailbreaking an iOS device to gain root access. Various tools are installed to analyze apps, including intercepting network traffic both passively and by acting as an HTTP proxy gateway. The document also covers monitoring local app data, binaries, and runtime analysis for black-box security testing of iOS apps.
This document discusses various techniques for sandboxing untrusted code, including chroot jails, system call interposition, virtual machines, and software fault isolation. It notes that completely isolating applications is often inappropriate, as they need controlled ways to communicate. The key challenges are implementing reference monitors to enforce isolation policies and specifying the right policy for each application to define what behavior is allowed.
The document discusses reducing attack surfaces in cloud environments. It notes that understanding your attack surface is critical for deploying proper security controls as attack surfaces differ between cloud and on-premises environments. It also states that web application attacks are now the leading cause of data breaches but less than 5% of security budgets are spent on application security. Common cloud misconfigurations are also discussed as a major risk factor.

Beyond the Pentest: How C2, Internal Pivoting, and Data Exfiltration Show Tru...Beau Bullock
Your vulnerability scanner reports that there are no issues on your network. A pentester has spent the last week trying to exploit every system your organization owns with no luck. The check box for this year's compliance audit has been checked. While it is good that these things occurred, they do not complete the picture in regards to true risk.
Real attackers do not solely rely on software exploits to compromise an environment. In almost every breach you hear about the root of the compromise came from a phishing attack. This is why additional tests, post-infection, should be performed to assess just how far an attacker can go after gaining a foothold into your environment.
What command and control channels are available for an attacker to utilize to communicate with your internal systems? How easy is it for an attacker to move laterally within your environment and gain access to other systems? What are your detection capabilities when it comes to sensitive data being exfiltrated out of your environment? How do you test these attacker techniques using open-source tools?
This lecture will address these questions and more, including a showcase of attacker methodologies.
Secure active directory in one day without spending a single dollarDavid Rowe
This document discusses securing Active Directory without spending money. It describes Active Directory and why access control is important. Privilege creep can occur over time as user accounts gain more access to objects like computers, groups and other users. This expands the attack surface for attackers. The document outlines Microsoft's Enhanced Security Administrative Environment (ESAE) solution in 3 stages with 14 steps to better separate administrative duties and limit administrative access. It provides an example of how a breach could occur if an unpatched public web server is compromised, allowing an attacker to gain domain administrator access. The document recommends two initial steps: 1) limit the number of administrative users and 2) create separate administrative accounts to better restrict administrative privileges.
The Unintended Risks of Trusting Active DirectoryWill Schroeder
This presentation was given at Sp4rkCon 2018. It covers the combination of Active Directory and host-based security descriptor backdooring and the associated security implications.
This document summarizes a presentation on bridging the gap between penetration testing and red teaming using offensive PowerShell techniques. It introduces Empire, a pure PowerShell post-exploitation agent, and discusses how weak standard images, dirty networks, and domain trusts can be exploited to escalate privileges and move laterally. Various PowerShell modules for tasks like credential dumping, code execution, and lateral movement are demonstrated.
Case Study: Privileged Access in a World on TimeCA Technologies
Today there are more privileged users than ever before. Providing access is not optional it is a business necessity. But how do you avoid excessive access? Providing the right access at the right time is the formula for reducing your risk and securing a world of data. At FedEx empowering the right people at the right time is not only good business, but it's also good security.

This document provides an introduction to WordPress security given by Chris Dodds to the Oklahoma City WordPress User Group. It discusses common WordPress security threats like script kiddies, hacktivists, professional criminals and information warriors who try to enumerate and exploit sites. Password attacks are highlighted as a major risk, and a backdoor code in the ToolsPack plugin is shown as an example. Best practices for security include updating plugins and WordPress core, backing up sites, using strong unique passwords, disabling unused plugins, and using security plugins like Better WP Security. The presenter provides his contact information for questions.
The document discusses various techniques for hacking systems, including password cracking, privilege escalation, executing applications remotely, and using keyloggers and spyware. It provides an overview of tools that can perform functions like password cracking, sniffing network traffic, capturing credentials, escalating privileges, executing code remotely, and logging keystrokes covertly. Countermeasures to these techniques, like disabling LM hashes, changing passwords regularly, and using antivirus software, are also covered.
Exploiting Active Directory Administrator InsecuritiesPriyanka Aash
"Defenders have been slowly adapting to the new reality: Any organization is a target. They bought boxes that blink and software that floods the SOC with alerts. None of this matters as much as how administration is performed: Pop an admin, own the system. Admins are being dragged into a new paradigm where they have to more securely administer the environment. What does this mean for the pentester or Red Teamer?
Admins are gradually using better methods like two-factor and more secure administrative channels. Security is improving at many organizations, often quite rapidly. If we can quickly identify the way that administration is being performed, we can better highlight the flaws in the admin process.
This talk explores some common methods Active Directory administrators (and others) use to protect their admin credentials and the flaws with these approaches. New recon methods will be provided on how to identify if the org uses an AD Red Forest (aka Admin Forest) and what that means for one hired to test the organization's defenses, as well as how to successfully avoid the Red Forest and still be successful on an engagement.
Some of the areas explored in this talk:
Current methods organizations use to administer Active Directory and the weaknesses around them.
Using RODCs in the environment in ways the organization didn't plan for (including persistence).
Exploiting access to agents typically installed on Domain Controllers and other highly privileged systems to run/install code when that's not their typical purpose.
Discovering and exploiting an AD forest that leverages an AD Admin Forest (aka Red Forest) without touching the Admin Forest.
If you are wondering how to pentest/red team against organizations that are improving their defenses, this talk is for you. If you are a blue team looking for inspiration on effective defenses, this talk is also for you to gain better insight into how you can be attacked."
This document discusses tactics for red team operations on Windows networks. It begins by covering techniques for gaining initial access and situational awareness, such as using PowerShell commands to enumerate users, computers, and network information. It then discusses abusing domain trust relationships and using PowerView to operate across trusts. Escalation techniques like PowerUp for privilege escalation and Mimikatz for token manipulation are also covered. The document discusses persistence methods like Golden Tickets and WMI. It finally covers techniques for locating and accessing file shares to retrieve sensitive information, using PowerView commands. The overall message is that while tactics remain the same, tools and implementations are continually evolving to facilitate red team operations.
Bridging the Gap: Lessons in Adversarial Tradecraftenigma0x3
This document discusses bridging the gap between penetration testing and red teaming using offensive PowerShell techniques. It describes how standard Windows images often have vulnerabilities, dirty networks with outdated users and services provide easy targets, and domain trusts allow access between organizations. The authors promote the Empire PowerShell agent for post-exploitation, highlighting modules for execution, credential theft, and lateral movement. They provide examples using Empire to inject into processes and extract credentials with Mimikatz.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
