🦑Windows Defender Bypass 2024 with AES-Encrypted Malicious DLL.

Hello everyone,
Since a lot of you guys enjoyed the last video, I decided to create another bypass technique—this time using AES encryption for the shellcode. To make it more interesting, I incorporated the shellcode into a malicious DLL and executed it using another process.

Here’s how it works:

I created a simple file, test.exe (the process I mentioned), which loads the malicious DLL containing the encrypted shellcode. This is achieved using the LoadLibraryA() function and the GetProcAddress() function which is essential for loading any DLL and their exported functions into a process's memory. Once loaded, the DLL decrypts and executes the shellcode.

This time malicious DLL contained raw encrypted shellcode stored on disk. The encryption prevents detection by Windows Defender. In my previous approach, the shellcode was hosted on a server, making it a staged payload. While experimenting, I also tried XOR to obfuscate the shellcode like last time. However, it was consistently detected for some reason I still don’t understand.XORing the shellcode and AES encrypting it share a similar concept though.I might be wrong on this one, forgive me if I am.

This method can be implemented in various ways. One approach is to inject the DLL into another process using its PID or using this AES method to just execute the malicious exe to run the shellcode in memory without loading the dll. This technique has been used by APTs as a means of achieving persistence on compromised systems they target.

I used multiple resources from the internet. All the code used do not belong to me. I added custom logic(like calling the exported function) and tweaked it a little bit to make it work like the way I wanted it to. I give credit to the internet.Hope you guys find this useful!

🦑𝐗𝐒𝐒 𝐓𝐡𝐫𝐨𝐮𝐠𝐡 𝐇𝐑𝐄𝐅 𝐔𝐑𝐋𝐬 👇

I often see applications that let their users control URLs which are reflected back in the DOM as part of the HREF tag

Most of the time these features let you:

• set the integration URL with a 3rd party service
• customize your profile page with a link to your own blog/website
• link your account to you social media profile

While sometimes developers use HTML encoding on quotes to block attackers from escaping the tag, there are several ways to trigger XSS inside href tags <without> escaping them.

One of them is to provide a valid URL format (to bypass server-side validation) but use the javascript protocol (instead of http which is what most developers would expect)

Note however that this won't work if the target="_blank" is specified

🦑🔍 Mastering DNS & DHCP Penetration Testing: Protect Your Network’s Core!

DNS (Domain Name System) and DHCP (Dynamic Host Configuration Protocol) are foundational to network operations. However, their vulnerabilities can make them prime targets for cyberattacks. Understanding how to test and secure these protocols is a critical skill for any cybersecurity professional.

Common DNS Vulnerabilities & Attacks:

1️⃣ DNS Spoofing/Poisoning: Alters DNS responses to redirect users to malicious websites.
2️⃣ DNS Tunneling: Exfiltrates data or establishes backdoors via DNS queries.
3️⃣ Cache Poisoning: Manipulates DNS cache entries to disrupt or redirect traffic.
4️⃣ Zone Transfer Exploitation: Misuses misconfigured servers to access sensitive DNS records.

Common DHCP Vulnerabilities & Attacks:

1️⃣ DHCP Starvation Attack: Exhausts IP leases, causing network disruptions.
2️⃣ Rogue DHCP Server Attack: Deploys unauthorized DHCP servers to provide malicious configurations.
3️⃣ Man-in-the-Middle (MITM) Attacks: Exploits DHCP to intercept sensitive data.
4️⃣ IP Address Spoofing: Mimics authorized devices to gain network access.

Steps to Perform DNS & DHCP Penetration Testing:

1️⃣ Reconnaissance:
• Use tools like Dig, DNSRecon, and Fierce to identify DNS configurations.
• Scan for active DHCP servers using DHCPig or Yersinia.

2️⃣ Vulnerability Analysis:
• Check for weak configurations in DNS records (e.g., open zone transfers).
• Identify rogue DHCP servers or insufficient IP allocations.

3️⃣ Exploitation:
• Simulate DNS Spoofing or Cache Poisoning to test resilience.
• Perform DHCP Starvation or Rogue Server attacks in a controlled environment.

4️⃣ Remediation:
• Harden DNS configurations (disable unused services, restrict zone transfers).
• Enable DHCP snooping and IP source guard to prevent rogue DHCP servers.

Pro Tip for Defenders:
• Implement DNSSEC (Domain Name System Security Extensions) to validate DNS responses.
• Regularly monitor and test DHCP and DNS servers for vulnerabilities.

📌 Remember: Always test ethically with proper authorization!

🔐 DNS and DHCP are the backbone of every network. Securing them not only prevents breaches but ensures smooth operations for businesses.

🦑Cookie stealer which can then be used for session hijacking and Bypassing 2 Factor Authentication:

>> How Does it work?
Big-Papa utilizes malicious javascript code injection...and then makes a GET Request(with cookies) to the Python Web server running on the attacker machine

Note That you need to be man in the middle in order to inject the malicious javascript Code and then steal cookies of the website that the victim is currently visting

For testing purposes copy the Javascript code from the bgp.js file without the script tags and execute in the console of the browser

You can use Bettercap in-order to become man-in-the-middle using bettercap or use arp spoof and then run Big-Papa to inject Javascript

>> For HTTPS?
Big-Papa will work Perfectly against HTTP websites but For HTTPS you can use sslstrip to Downgrade it to HTTP and then utilize Big-Papa

*SSLstrip --> https://github.com/moxie0/sslstrip.git

Still some websites use HTTP and thus their data including Passwords can be read in Clear text but we need to steal cookies in some cases in order to Bypass 2-Factor-Authentication

🄸🄽🅂🅃🄰🄻🄻🄸🅂🄰🅃🄸🄾🄽 & 🅁🅄🄽 :

1️⃣ git clone https://github.com/vrikodar/Big-Papa.git

2️⃣cd Big-Papa

3️⃣chmod +x install.sh

4️⃣ ./install.sh

A playbook, also known as a standard operating procedure (SOP), consists of a set of guidelines to handle security incidents and alerts in the SOC.

Incident response methodologies typically involve creating standard operating procedures (SOPs), playbooks, and runbooks to guide teams through the incident response process.

These gudelines provide easy to use operational incident best practices. These cheat sheets are dedicated to incident handling and cover multiple fields in which a CERT team can be involved.
