This document proposes a new methodology for web application testing that involves testing a system administrator's ability to detect an attack. It suggests conducting a staged test with increasing levels of noise or detection to see when the admin is able to identify an attack. The document also provides examples of how attackers hide connections and clear logs to avoid detection by discussing typical behaviors checked by incident response teams. The goal is to test both the security of the application and the security of the admin's knowledge to help admins learn new ways that attacks can be hidden and to improve security overall.

A computer virus is a malicious program that attaches itself to other files and programs to spread without permission. It can slow down or crash an infected computer by using system resources. A Trojan horse also spreads maliciously but does not replicate, instead masquerading as a desirable program. A worm replicates like a virus but spreads through networks instead of attaching to files. Antivirus software with up-to-date definitions is the best protection, but it requires regular updates after subscriptions expire. Backing up important data files regularly and storing backups separately is also crucial, as hardware and files will inevitably fail or become corrupted.

Microsoft Patch Management For Home Users outlines the importance of installing security patches for home computers connected to the internet. Older operating systems like Windows 98 require users to manually check for updates, while Windows XP Service Pack 2 automatically notifies users of available patches. Microsoft recommends installing patches immediately for security, but allowing time to test patches on less critical systems first. When installing patches, users should create a restore point, allocate an hour of time in case issues arise, and wait a few days if deadlines are approaching to avoid problems.

Checking Windows for signs of compromise
This document provides guidance on investigating compromised Microsoft Windows systems to identify how the system was compromised and what malware or unauthorized programs may be present. It outlines various locations in the file system, registry, services, and network settings where intruders commonly hide malware. Tools recommended for examining the system include using cmd.exe to view file timestamps, searching hidden folders and alternate data streams, and using Google to research any suspicious programs found. The document advises that while antivirus software can detect some threats, a fresh reinstall of the operating system is typically the most reliable way to restore a compromised system.
When love kills
The document discusses email viruses and how to identify hoax warnings about viruses. It provides the following key points:
1. Email viruses spread when users click on infected attachments, not just by opening the email itself. The "I Love You" virus spread this way.
2. Hoax warnings about viruses can be identified by ALL CAPS words, excessive exclamation points, and messages telling users to forward the email. Legitimate virus alerts do not ask users to forward warnings.
3. Resources like Symantec and Stiller Research can be used to look up virus warnings and identify hoaxes. Hoaxes outnumber actual new viruses in warnings users receive.
Some basics of computer security
Virus infections can seriously impair computers and damage businesses by destroying the system registry or the entire computer. Viruses slow down computers by causing the screen to get stuck in programs or making the keyboard stop working, and may prevent the computer from booting. To protect against viruses, it is important to always have the firewall turned on, keep programs and software updated with necessary service packs, run antivirus software daily using a paid rather than free version, update antispyware/adware weekly to maintain computer speed, enable pop-up blocking, be wary of suspicious emails and files from messengers, and take care when downloading programs. Botnets work by infecting computers with viruses that allow hackers to remotely control large networks of compromised
The present and future of serverless observability
The present and future of serverless observability involves overcoming new challenges presented by serverless architectures. These challenges include not having access to install agents or daemons on functions, no ability to perform background processing, higher concurrency of requests to logging and metrics systems, and a high chance of data loss due to batching. Observability tools need to evolve to provide a bird's eye view of the entire system as asynchronous functions interact, and help debug interactions between functions and external services.

Applying principles of chaos engineering to Serverless
Chaos engineering is a discipline that focuses on improving system resilience through experiments that expose the inherent chaos and failure modes in our system, in a controlled fashion, before these failure modes manifest themselves like a wildfire in production and impact our users.
Netflix is undoubtedly the leader in this field, but much of the publicised tools and articles focus on killing EC2 instances, and the efforts in the serverless community has been largely limited to moving those tools into AWS Lambda functions.
But how can we apply the same principles of chaos to a serverless architecture built around AWS Lambda functions?
These serverless architectures have more inherent chaos and complexity than their serverful counterparts, and, we have less control over their runtime behaviour. In short, there are far more unknown unknowns with these systems.
Can we adapt existing practices to expose the inherent chaos in these systems? What are the limitations and new challenges that we need to consider?

An Introduction to Prometheus (GrafanaCon 2016)
Often what you monitor and get alerted on is defined by your tools, rather than what makes the most sense to you and your organisation. Alerts on metrics such as CPU usage which are noisy and rarely spot real problems, while outages go undetected. Monitoring systems can also be challenging to maintain, and overall provide a poor return on investment.
In the past few years several new monitoring systems have appeared with more powerful semantics and which are easier to run, which offer a way to vastly improve how your organisation operates and prepare you for a Cloud Native environment. Prometheus is one such system. This talk will look at the monitoring ideal and how whitebox monitoring with a time series database, multi-dimensional labels and a powerful querying/alerting language can free you from midnight pages.
Introduction To Ethical Hacking
Hacking involves exploiting vulnerabilities in computer systems or networks to gain unauthorized access. There are different types of hackers, including white hat hackers who perform ethical hacking to test security, black hat hackers who perform hacking with malicious intent, and grey hat hackers who may sometimes hack ethically and sometimes not. Ethical hacking involves testing one's own systems for vulnerabilities without causing harm. Vulnerability assessments and penetration tests are common ethical hacking techniques that involve scanning for vulnerabilities and attempting to exploit them in a controlled way. Popular tools used for ethical hacking include Kali Linux, Nmap, Metasploit, and John the Ripper.

Security engineering 101 when good design & security work together
Security concerns are often dealt with as an afterthought—the focus is on building a product, and then security features or compensating controls are thrown in after the product is nearly ready to launch. Why do so many development teams take this approach? For one, they may not have an application security team to advise them. Or the security team may be seen as a roadblock, insisting on things that make the product less user friendly, or in tension with performance goals or other business demands. But security doesn’t need to be a bolt-on in your software process; good design principles should go hand in hand with a strong security stance. What does your engineering team need to know to begin designing safer, more robust software from the get-go?
Drawing on experience working in application security with companies of various sizes and maturity levels, Wendy Knox Everette focuses on several core principles and provides some resources for you to do more of a deep dive into various topics. Wendy begins by walking you through the design phase, covering the concerns you should pay attention to when you’re beginning work on a new feature or system: encapsulation, access control, building for observability, and preventing LangSec-style parsing issues. This is also the best place to perform an initial threat model, which sounds like a big scary undertaking but is really just looking at the moving pieces of this application and thinking about who might use them in unexpected ways, and why.
She then turns to security during the development phase. At this point, the focus is on enforcing secure defaults, using standard encryption libraries, protecting from malicious injection, insecure deserialization, and other common security issues. You’ll learn what secure configurations to enable, what monitoring and alerting to put in place, how to test your code, and how to update your application, especially any third-party dependencies.
Now that the software is being used by customers, are you done? Not really. It’s important to incorporate information about how customers interact as well as any security incidents back into your design considerations for the next version. This is the time to dust off the initial threat model and update it, incorporating everything you learned along the way.

Bsides Tampa Blue Team’s tool dump.
This document provides an overview of various cybersecurity tools and concepts. It begins by explaining security information and event management (SIEM) tools and what logs they can ingest. It then discusses intrusion detection systems (IDS) versus intrusion prevention systems (IPS) and how they work. Next, it covers endpoint detection and response (EDR) tools, open source alternatives, and how they can provide threat hunting capabilities. The document concludes by discussing the importance of vulnerability assessment and patching systems to reduce risk.
The Top 10/20 Internet Security Vulnerabilities – A Primer
This document summarizes the top 10 internet security vulnerabilities presented by Randy Marchany at a computing conference. It discusses each vulnerability in the list, including BIND vulnerabilities that allow hackers to control nameservers, CGI script vulnerabilities that can be used to modify websites, and RPC vulnerabilities that permit remote access to systems.

A trojan is a type of malware that appears to perform a desirable function but hides malicious code that allows unauthorized access to a system. Some key points about trojans:
- Trojans are often disguised as legitimate files to trick users into running them. Common file types used for trojans include executable files (.exe), dynamic link libraries (.dll), scripts (.vbs, .js), and compressed files (.zip, .rar).
- Once activated, a trojan may allow attackers to install additional malware, steal data, use system resources for cryptomining or DDoS attacks, and more.
- Common trojan delivery methods include email attachments, compromised/malicious websites, peer-to-

- 7. “WITH CONTACT BETWEEN TWO ITEMS, THERE WILL BE AN EXCHANGE”
- 8. Every action you take will always leave a trace. Even when the action is to cover or delete the trace of another action. You will not only leave artefacts and traces on the target system but also on some of the devices you transit and communicate through. ?
- 9. Developers may create vulnerable code (always has and always will be a problem) Another problem however, that I don’t believe is looked at is: At what stage to SysAdmin’s know that their system is being attacked / is this early enough? Problem?
- 11. Create part of a testing stage that the SysAdmin’s can join in with! A low to high noise area of testing. What does this mean? Idea?
- 12. Checklist or Testing Guide. Make sure that the SysAdmin is aware of what is going to happen and ask them to co-operate. Plan a low – medium – high framework that can used. See where the SysAdmin picks it up. Incorporate this into the report. Idea (2)?
- 13. It is all well and good know you have been attacked, but the fact you don’t know when is when you need to worry. What information has been compromised. Idea (3)?
- 14. Not all companies have IR Teams Low hanging fruit with be checked first: Processes, connections, EventLog and in some cases memory dumps Knowing your enemy
