🦑This one command is enough to knock down your entire wifi.

-S : Send syn packets
--flood : Sent packets as fast as possible

Simple DOS attack, works really well on non-enterprise networks. Implement firewall/filter rules in your router to avoid these attacks.

However in some cases it can increase resources usage on router that could still lead to crashes.

🦑P11-Malware Development for Red Teamers.

Structure of a Portable Executable (PE) file
-----
MS-DOS Header

Located at the very beginning of the PE file, this header ensures backward compatibility with MS-DOS systems. It starts with the signature "MZ" (hexadecimal 4D5A) to indicate that the file is an executable. The header also includes metadata and, most importantly, a pointer (at the e_lfanew field) to the location of the PE signature, which marks the start of the Windows-specific portion of the file.
-
MS-DOS Stub

Following the MS-DOS Header is a small program, known as the DOS Stub, that displays a message if the file is run in an MS-DOS environment. Typically, this message is: "This program cannot be run in DOS mode." While it serves no purpose on modern Windows systems, it remains in the file for compatibility reasons.
-
PE Signature

This marks the beginning of the Portable Executable (PE) format. The signature is always PE\0\0 (hexadecimal 50 45 00 00), signaling that the file conforms to the PE standard. This signature separates the DOS-specific data from the Windows-specific data.
-
File Header

Following the PE Signature, the File Header contains critical information about the executable. This includes details like the target machine type (e.g., x86 or x64), the number of sections, the timestamp of file creation, and flags indicating the file's characteristics. It acts as a roadmap for understanding the executable's overall structure.
-
Optional Header

Despite its name, this header is mandatory for executable files. It provides essential details such as the entry point (the starting address for execution), the image base (preferred memory location), and sizes of various segments. This header bridges the gap between the high-level structure of the file and its low-level memory layout.
-
Section Headers (PE Sections)

These headers define the various sections of the executable, such as .text (code), .data (initialized data), and .rdata (read-only data). Each section header specifies attributes like the section's size, location in memory, and access permissions. These sections contain the actual content of the program, including its instructions, data, and resources.

🦑DNS Record Types You Should Know!

Here are the 8 most commonly used DNS Record Types.

1 - A (Address) Record
Maps a domain name to an IPv4 address. It is one of the most essential records for translating human-readable domain names into IP addresses.

2 - CNAME (Canonical Name) Record
Used to alias one domain name to another. Often used for subdomains, pointing them to the main domain while keeping the actual domain name hidden.

3 - AAAA Record
Similar to an A record but maps a domain name to an IPv6 address. They are used for websites and services that support the IPv6 protocol.

4 - PTR Record
Provides reverse DNS lookup, mapping an IP address back to a domain name. It is commonly used in verifying the authenticity of a server.

5 - MX Record
Directs email traffic to the correct mail server.

6 - NS (Name Server) Record
Specifies the authoritative DNS servers for the domain. These records help direct queries to the correct DNS servers for further lookups.

7 - SRV (Service) Record
SRV record specifies a host and port for specific services such as VoIP. They are used in conjunction with A records.

8 - TXT (Text) Record
Allows the administrator to add human-readable text to the DNS records. It is used to include verification records, like SPF, for email security.

Over to you: Which other DNS Record Type have you seen?

🦑What is Honeypot: Simplified

Follow Santosh Nandakumar for daily simplified infosec learnings.

A honeypot is a security mechanism designed to detect, deflect, or study hacking attempts by acting as a decoy system. It looks like a legitimate target but is isolated from the actual network to gather intelligence on attackers.

Example

Imagine you’re protecting a house (your network) from burglars. You set up a fake house nearby, filled with dummy valuables. Burglars are attracted to this fake house, thinking it’s the real one. You monitor their actions to learn their techniques and better secure your actual house.

Technical Example

You deploy a honeypot server within your corporate network that mimics a database server. It contains no real data but appears authentic to attackers. When an attacker tries to access it, their activities (such as IP, methods, and tools) are logged for analysis.

Types of Honeypots

1. Production Honeypot
Used to improve overall security by distracting attackers from real systems.
Example: A fake customer login page for a banking website.

2. Research Honeypot
Used for studying attack methods and gathering intelligence.
Example: A honeypot server that simulates IoT devices to study botnet attacks.

Usage

- Intrusion Detection: Identify unauthorized access attempts.

- Threat Intelligence: Understand attackers' tools, techniques, and goals.

- Deception Strategy: Divert attackers away from real resources.

- Vulnerability Testing: Study how attackers exploit weaknesses.

Benefits

1. Early Threat Detection: Identifies threats before they reach critical systems.

2. Data Collection: Offers valuable insights into attack patterns and behaviors.

3. Improved Defense: Helps in identifying security gaps and improving defenses.

4. Resource Efficiency: Reduces the workload on actual systems by diverting attacks.

5. Training Ground: Useful for security teams to practice handling real-world threats.

Limitations

1. Limited Scope: Cannot detect attacks on systems outside the honeypot.

2. Risk of Exploitation: If not properly isolated, attackers could use the honeypot to attack real systems.

3. Resource Intensive: Requires setup, monitoring, and maintenance.

🦑AI-SOC. Radiant Security AI.

I have had many conversations (and still have) about Security for AI, especially about how AI-SOC can affect and help the SOC team and processes. At the same time, We have been (xTriage) running Radiant Security AI as AI-SOC (and more) for over a year, and the results arrived on time with HUGH successes!

During the AI-SOC journey with Radiant Security AI, we found many advantages about it. Below are some of them (in a nutshell):

1️⃣ Proactive Threat Hunting: AI-SOC leverages real-time data analysis and threat intelligence to proactively detect emerging threats, even before they appear in known threat databases.

2️⃣ Precision in Incident Detection: AI models analyze massive datasets and correlate events across multiple layers (network, endpoints, cloud, identities), reducing detection blind spots.

3️⃣ Scalability: AI-SOC can handle the massive influx of security alerts and scale effortlessly with an organization's growth without requiring linear increases in human resources.

4️⃣ Behavioral Anomaly Detection: AI identifies subtle deviations from normal behavior patterns that traditional systems often overlook, ensuring early detection of insider threats and zero-day exploits.

5️⃣ Hyperautomation: Combining AI with SOAR platforms enables faster and smarter incident response. Automated workflows triage and contain incidents without waiting for human intervention.

6️⃣ Continuous Learning and Adaptation: AI algorithms evolve with each new threat encountered, continuously improving their accuracy and relevance in detecting sophisticated attacks.

7️⃣ Enhanced Collaboration: AI-SOC tools facilitate collaboration across security tiers (T1-T3), presenting data and insights in clear, actionable formats tailored to the expertise level of the analyst.

8️⃣ Integrated Multi-Vendor Ecosystem: With support for seamless integration into existing ecosystems (e.g., XDR tools, SIEMs, SOAR), AI-SOC ensures minimal workflow disruption.

9️⃣ Reduction in False Positives: By understanding context and correlating events, AI dramatically reduces false positives, allowing analysts to focus on genuine threats.

🔟 Cost Efficiency: By automating repetitive tasks and reducing the need for manual intervention, AI-SOC optimizes resource utilization and lowers the overall cost of operations.

In the end, T1/T2 is not chasing after massive FPs or useless alerts - They are now doing advanced tasks.

🦑Understanding the Network Protocol Stack Simplified 🛠️

Networking is the backbone of modern communication, but the variety of protocols can feel overwhelming. Here's a clean breakdown of the Network Protocol Stack, from physical data transmission to application-level interactions:

🟪 Application Layer (L5-L7)
Where user-facing magic happens! Think web browsing, secure communication, and directory services (e.g., HTTP, TLS, DNS).

🟦 Transport Layer (L4)
Handles data delivery, reliable (TCP) or quick (UDP). New protocols like QUIC ensure modern needs are met.

🟥 Network Layer (L3)
Focuses on routing and addressing, whether through IPv4 or IPv6, with security layers like IPsec keeping it safe.

🟩 Data Link Layer (L2)
Close to hardware , responsible for switching, VLANs, and WiFi connectivity.

I recently watched one of DEFCON's talk of this year "Your CI CD Pipeline Is Vulnerable, But It's Not Your Fault" by Elad Pticha, Oreen Livni and was really impressed by the attack vector (link in comments)

𝐋𝐞𝐭'𝐬 𝐬𝐞𝐞 𝐡𝐨𝐰 𝐢𝐭 𝐰𝐨𝐫𝐤𝐬

Github workflows are part of the CI/CD (Continous Integration/Continous Deployment) ecosystem that lets developers automate their workflow

For example: once a commit is made to the repo -> the code is scanned with a tool -> if the tests pass -> code is pushed to test/production

Now the interesting part is that (if the repo maintainer uses input that you control) inside the workflow, this can lead to command injection in the pipeline

𝐖𝐡𝐢𝐜𝐡 𝐦𝐞𝐚𝐧𝐬 𝐲𝐨𝐮 𝐦𝐚𝐲 𝐛𝐞 𝐚𝐛𝐥𝐞 𝐭𝐨 𝐭𝐚𝐤𝐞 𝐨𝐯𝐞𝐫 𝐭𝐡𝐞 𝐫𝐞𝐩𝐨

In the example bellow, the pipeline uses the title of an issue as part of a bash echo command

That means anyone can create a issue named $(𝐰𝐡𝐨𝐚𝐦𝐢) and execute commands in the CI/CD

If you can do that -> you can abuse the command injection to steal the repo's Github token, read secrets or push malicious code
