πŸ¦‘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.

▁ β–‚ β–„ Uπ•Ÿπ”»β’Ίπ«6𝔬𝓓ⓔ β–„ β–‚ ▁

πŸ¦‘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 β€œNikiforov 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 β€œdeputy 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 (β€œbecause 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 β€œtechnical” punctures: a simple SSH connection password (β€œno 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

πŸ¦‘Do I need to use Tor with VPN, proxy, SSH?


> This is a common question in different variations. And there is no definite answer to it. Suppose in my country or my Internet service provider is blocking access to the Tor network, then not so much good as the only solution is to use VPN + Tor. At the same time,

> so i must clearly understand the risks of a VPN, which is designed for organizing virtual private networks, and not anonymity. If I DO NOT understand the risks of adding different intermediate nodes, and I just do it because I read something better on some forum, then this is a bad idea: there is no working technology to find out the real IP address of a Tor network user, but VPN β€œhoneypot "Will know everything about you:

1️⃣your real IP address

2️⃣what sites did you make requests to
what answers received

3️⃣Further translation from the pages of the official Tor Project documentation. I agree with these views, provided that there is trust in the Tor network. I do NOT have 100% trust in the Tor network, but of the other options for hiding my IP, this is the best solution.

πŸ¦‘Anonymity and privacy

> You can very much violate your anonymity by using VPN / SSH in addition to Tor. (Proxies are described below.) But if you know what you are doing, then you can increase anonymity, security, and privacy.

> VPN / SSH providers keep a history of financial transactions and you will leave traces if you do not choose a truly anonymous payment method. VPN / SSH acts as a permanent ingress or as a persistent egress node. This may solve some problems, but create new risks.

> Who is your opponent? Against a global adversary with unlimited resources, adding new intermediate nodes makes passive attacks (a bit) harder, but active attacks become easier as you provide more surface to attack and send more data that you can use.


> Adding hosts strengthens you against collusion between Tor hosts and against blackhack hackers who target the Tor client code (especially if Tor and VPN work on two different systems).

> If the VPN / SSH server is under the control of an attacker, you are weakening the protection provided by Tor. If the server is trustworthy, you can increase the anonymity and / or privacy (depending on the settings) provided by Tor.

> VPN / SSH can also be used to circumvent Tor censorship (if your ISP blocks access to Tor or if the end node blocks connections from the Tor network).

πŸ¦‘VPN / SSH vs proxy :


> The connection between you and the VPN / SSH is encrypted, but not always.

> On the other hand, the connection between you and OpenProxy is not encrypted. The "SSL proxy" in most cases is the only http proxy that supports the connect method. The connect method was originally designed so that you can use SSL connections to web servers, but other interesting things are possible, such as connecting to IRC, SSH, etc.

> Another disadvantage of http (s) proxies is that some of them, even depending on your network settings, even pass your IP through the β€œhttp forwarded for” header . (Such proxies are also called β€œnon-anonymous proxies.” Although the word β€œanonymous” should be understood with caution in any case, OpenProxy alone is much worse than Tor.)

πŸ¦‘VPN vs SSH or proxy :

> VPN works at the network level. The SSH tunnel can offer socks5 proxies. Proxies work at the application level. These technical details create their own problems when combined with Tor.

> The problem for many VPN users is the complicated setup. They connect to the VPN on a machine that has direct access to the Internet.

> VPN user may forget to connect to VPN first
Without special precautions, when a VPN connection is disconnected (VPN server reboot, network problems, VPN process failure, etc.), direct connections without VPN will be performed.
To solve this problem, you can try something like VPN-Firewall.

> When working at the application level (using socks5 SSH tunnels or proxy servers), the problem is that many applications do not comply with the proxy server settings.

> The most secure solution to resolve these problems is to use a transparent proxy, which is possible for VPN, SSH and proxies.

πŸ¦‘Why Use Password Managers ?
#FastTips

The main rules for the safe use of passwords:

>the password must be complex (i.e. include 4 groups of

>characters - uppercase and lowercase letters, numbers, special

>characters - and not consist of words or a combination of them that can be found in the dictionary)

>you cannot use the same password on different sites and services, because compromising your password, for example, on a poorly protected site / forum, can give an attacker access to your mail, cloud storage, social networks, network folder, etc.

>passwords should not be stored on a computer in text files, as well as in public places (a sticker with a password on a computer is also bad)

>Under these conditions, you need to remember a large number of complex passwords, which is practically impossible. Therefore, many users do not comply with these conditions (which is bad), and those who comply are forced to write passwords, for example, to a text file (if the file is not encrypted, then this is also bad).

πŸ¦‘A password manager can help in this situation - a program that stores your password in encrypted form. That is, instead of many passwords, you only need to remember one master password.
