🦑Top Password Reset Functionality Bugs
🛡️
Testing password reset flows is critical to ensuring account security. Here’s a checklist of common vulnerabilities to watch out for:

No rate limiting

Token leakage

Email manipulation

Self-XSS risks

Brute force reset attempts

Each of these bugs can lead to serious account takeovers (critical vulnerability) if overlooked. What other password reset vulnerabilities have you come across in your tests?

-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.

🦑Top Shodan Dorks for Finding Sensitive IoT Data 🌐

Are you testing IoT devices and systems for vulnerabilities? Shodan, the search engine for internet-connected devices, can reveal critical data with the right queries.

This cheat sheet contains useful Shodan dorks to identify exposed services, misconfigurations, and unsecured devices, such as: ✅ Open ports: 23 (Telnet), 21 (FTP), 3306 (MySQL)
✅ Exposed services: PostgreSQL, MongoDB, Apache, Jenkins, MikroTik
✅ Sensitive information: "MongoDB Server Information," "200 OK" responses, and certificate details

Some highlights include:

Finding unprotected remote desktops (port:3389)

Identifying insecure databases (port:27017, MongoDB authentication disabled)

Locating industrial devices and firmware (port:5006,5007 Mitsubishi)


Why does this matter?
IoT devices are often overlooked and can serve as easy targets for attackers if not properly secured. By searching for exposed ports and services, security researchers can help organizations address these risks proactively.

📢 A friendly reminder: Use this knowledge responsibly. Only test systems you have permission to access!

🦑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?
