🦑Termux optimization :

> Terminal color
Mainly used zshto replace bashas the default shell. Use one-click installation script to install, one-step installation, by the way, external storage is started, and you can directly access the directory under the SD card.

1️⃣ Execute the following command to ensure that curl is installed

> sh -c "$(curl -fsSL https://github.com/Cabbagec/termux-ohmyzsh/raw/master/install.sh)"

2️⃣Android 6.0 and above will pop up a box to confirm whether it is authorized.

3️⃣After authorization, Termuxyou can easily access the SD card file. After the script allows, you have the following two options:

> Enter a number, leave blank to not to change: 14 Enter a number, leave blank to not to change: 6

> Select separately

> you want to continue to change the selection color, continue to run the script to filter again:

$ ~/termux-ohmyzsh/install.sh
exitRestart sessionssession effective configuration

4️⃣Access to external storage optimization :

> After executing the above zshone-click configuration script and granting file access permissions, a directory will be generated at home directory storageand several directories will be generated , and the soft links will all point to the corresponding directory of the external memory card

🦑VNC FOR BEGINERS
#FastTips

>The VNC Host: Display field is used to enter the host IP address and display number. In fact, usually the display number is not required.

>as example you can specify the port number if it differs from the standard one. The entries for IP: 1 (first display on IP) and IP: 5901 (port 5901 on IP) are identical. That is, 192.168.0.100:1 and 192.168.0.100:5901 for the program are one and the same.

> If after the colon you use the number <200, then the program thinks that you have indicated the display number and is trying to connect to port 5900 + n. If you need to use a TCP port less than 200, then specify a negative number, for example: 24.67.132.27:-80

In this field you can specify various protocols that will tell the program whether to use SSL, SSH, together or not to use anything at all. But, in my opinion, it’s easier to switch values in the graphical menu than to remember little-used notations.

>VNC Password - here you can specify the password for VNC authentication - you can leave the field blank and in this case the

>VNC viewer will display a password input dialog box.

>Proxy / Gateway - proxy and gateway, most users do not need this.

>Use SSL - use SSL
Use SSL + SSH - use SSL with SSH. This is usually not necessary, since SSH also provides encryption like SSL. In practice, it may be needed only with certain firewall settings to circumvent restrictions.

>None - do not use encryption, just start VNC viewer

>Save - save the profile with the entered settings

>Load - load a profile with the entered settings

Connecting with ssvnc using SSL
The server settings here and here said that you need to transfer the certificate to the client machine - it is this certificate that will be needed to encrypt traffic using SSL.

Important : SSL certificate can be replaced on the fly !!! That is, SSL encryption will prevent passive traffic interception, but if the attacker uses certificate substitution tools, then you are not protected from this attack!

🦑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.

🦑HACKERS REAL TIPS
#fAStTips

>Data-driven attack
A data-driven attack refers to an attack launched when a seemingly harmless special program sent or copied by a hacker to a target computer is executed. This attack allows hackers to modify files related to network security on the target computer, making it easier for hackers to invade the target computer next time. Data-driven attacks mainly include buffer overflow attacks, format string attacks, input verification attacks, synchronization vulnerability attacks, and trust vulnerability attacks.

>Forged information attack
Forged information attack refers to hackers sending fake routing information to construct a false path between the source computer and the target computer, so that the data packets flowing to the target computer pass through the computer operated by the hacker, so as to obtain the bank account in these data packets Personal sensitive information such as passwords.

>Attacks against information protocol weaknesses
In a local area network, the source path option of the IP address allows the IP packet to choose a path to the target computer. When a hacker tries to connect to an unreachable computer A located behind the firewall, he only needs to set the IP address source path option in the sent request packet, so that a destination address of the packet points to the firewall, but the final address points to Computer A. When the packet reaches the firewall, it is allowed to pass because it points to the firewall instead of computer A. The source path of the firewall's IP layer to process the message was changed and sent to the internal network, the message thus reached the unreachable computer A, thereby achieving a vulnerability attack on the information protocol.

>Remote control
Remote manipulation refers to a hacker launching an executable program in the target computer, the program will display a fake login interface, when the user enters account, password and other login information in the interface, the program will enter the account and password entered by the user To the hacker’s computer. At the same time, the program closes the login interface, prompting the message "System has failed" and asking the user to log in again. This attack is similar to phishing websites that are often encountered on the Internet.

>Attack by mistake of system administrator
In the local area network, people are one of the most important factors for the security of the local area network. When the system administrator makes mistakes such as configuration errors of the WWW server system and ordinary users expand user rights, these mistakes can provide hackers with an opportunity. Hackers use these mistakes, plus the command of finger, netstat, etc., to achieve intrusion attacks.

🦑Common errors leading to deanonymization:

1. Anonymity in social networks
If you are registered in vk (social network) by entering your phone number. Then they connected to vk via Tor in order to write “Nikiforov S.S. thief". Does this mean that you are anonymous - did you use Tor?

No, it doesn’t. If only because a phone number is tied to your social network account. And for your identification, the IP address is not particularly needed.

2. Anonymity and cookies
Cookies are small pieces of information that are stored in your web browser after the site sends them to you.

If you went to the site, received your cookies, then reconnected via Tor and wrote in the comments something like “deputy of the second convocation of the City Duma Petrov D.S. also a thief ”, then cookies can link the author of a comment and a user who has previously logged in with a different IP address.

Cookies are designed to identify the user regardless of your IP address.

3. Many sites store the IP of previous actions
For example, I registered a VPN account to which I will connect through Tor. But I registered it from my IP (“because Tor is slow, and indeed that site does not accept connections from the Tor network). Will I be anonymous if I connect to a VPN via Tor? No, because information about previous operations with the IP address is saved.

4. I WILL BUY a VPN (or VPS server to configure OpenVPN) and will be anonymous
Even if you read the third paragraph and went to register through Tor, but use wallets that can lead to you, then there is no question of any anonymity. Moreover, when buying one-time SIM cards and when entering the wallet sites, you also need to remember about your anonymity, otherwise it is all just meaningless.

That is why just Tor is more anonymous than Tor + OpenVPN. It is quite difficult to buy something without leaving a trace.

5. OpenVPN is very good, but not for anonymity
If we recall the original purpose of VPN networks, then this is an organization of virtual private networks, inside of which computers scattered around the world, can access each other's local network resources. At the same time, traffic exchange is encrypted, but this traffic is encrypted only for an external observer, but not for the server and clients of the OpenVPN network.

For this reason, if you purchased a free or paid VPN account, then be prepared that the server owner can do with your traffic WHAT PLEASANT and keeps activity logs - what requests were made from which client.

6. There are 1000 and 1 ways to find out the real IP address of a remote user
Options are from the simplest to send a link to a controlled site and see the IP (if communicating through an anonymous messenger) or a file with a trojan to completely sophisticated methods.

7. If you use any software with closed source code for illegal activities, then there is 100% backdoor installed
Backdoors can also be in legitimate software with closed source code - as a hard-to-detect vulnerability that the manufacturer knows about, or just an ordinary backdoor that is dumb like a cork - these were found, for example, in the official firmware of routers.

As for the illegal software with closed source code that is distributed anonymously, please tell me, well, why not install a backdoor there? The owner does not know anything, and even if he finds out what he will do? He’ll go to the police and say: I bought scripts to crack the protection of stolen phones, and they installed a virus there ... It’s unlikely that he will.


8. Misunderstanding of the simplest technical aspects of the operation of networks, servers, applications, information accumulated and available in open sources
In my articles, the links to which I gave above, I found the sites of the attacker simply by analyzing where the POST request goes. Why did the attacker leave scripts on this site in the archive? Apparently, I just did not know that it is very easy to track where the POST request goes even if the HTML code is obfuscated.

And there can be many such “technical” punctures: a simple SSH connection password (“no one knows where my server is”), a misunderstanding of what information the researcher can get on the server, a misunderstanding why Cloudflare is needed, etc.

9. The big picture
Example: infrastructure objects and IP traces are attacked and other indirect signs lead to somewhere far away. But at the same time, the objects and methods of attack are similar to those used by the well-known hacker group. At least there is reason to think.

10. Metadata in files
