What are the most common password cracking techniques and how can you prevent them?

1. Bruteforce Attack Use strong passwords, account lockouts, and rate limiting. 2. Dictionary Attack Avoid common words, use complex passwords. 3. Phishing Educate users, employ multi-factor authentication (MFA) 4. Keylogging Use anti-malware, keep systems updated. 5. Credential Stuffing Discourage password reuse, monitor for suspicious activity. 6. Rainbow Table Attack Use strong hashing, implement salt, update algorithms. 7. Man-in-the-Middle Attack Use secure channels, be cautious on public networks, use VPNs. 8. Social Engineering Educate users, establish clear communication protocols, encourage verification.

A lot of companies have a default first password for the new users which are vulnerable to these kind of attacks. Ideally post first login, the user should be forced to reset the password as per the organisations password policy

Attackers can easily generate huge password lists using leaks and dictionaries. If we consider that every word in existence is on these lists we have several options for a stronger password. 1) Salting: Adding random strings (numbers, letters, special characters) at the beginning or the middle of the word. 2) Using passphrases: An attacker can potentially try every word that exists but will need considerably more resources to try every phrase. 3) Combining both: Using a salted passphrase were the salt and passphrase will change regularly and for each service we use. Passphrases are not only effective against dictionary attacks but also useful against brute force attacks.

Another attacking method is a hybrid one, based on a mix between dictionary and brute force attack. This method is based on a typical behaviour based on the tendency that several times the new password is just as the previous one while only one number/char is added at the end. As soon as the original pwd is intercepted, the attacker is able to identify the new one using a brute-force attacking method.

Using the most common passwords like password, password123 etc is still followed by many people. Some even tell their password or how they setup the password which shouldn't be the case no matter who asks.

I think the most and stronger way to crack password is social engineering attacks , and this need time but it alwys succussed the way to prevents it is security awareness updated day by day for all member inside companies not only IT members but also non IT members

Having a strong password policy is the simplest and most effective way to thwart a brute-force attack. Create a complex password that is relatively easy to remember but impossible to guess. Secondly, limit login attempts and monitor IP addresses.

These days when we often use APIs while developing microservices based application. Some APIs are used for authentication or authorization. In the case of brute force attack the developer must make sure that rate limiting setting is applied to how often the API is called for similar inputs in order to deter brute force attack or Denial of Service attack. Rate limiting means to put the limit on the number of requests in a given span of time.

Brute force attack is the easiest to perform and can quickly get the low hanging/easiest to guess passwords. If someone were looking to crack passwords I would expect them to use dictionary and brute force. If they are smart they will customize the dictionary to the individuals and the company.

Brute Force attack can be considered as one of the easiest password cracking method. With no api rate limits issue being present in thr system, this attack is quite successfull. Its only downside is its too time consuming for big passwords. Generally nowdays, developers implement Captcha and api rate limit to tackle this issue.

Rainbow attacks, executed by Kali Linux tools like "John the Ripper" and "Hashcat," exploit hashed passwords. Furthermore we need to use a technique "Salting" which means practice of adding random data, known as a "salt," to passwords before they are hashed and stored in the database. Here's how salting typically works: 1) Random Data Generation: A unique random value (the salt) is generated for each user. 2) Combining with Password: The salt is then combined with the user's password before the password is hashed. This means that even if two users have the same password, their hashed values will be different due to the unique salt.The hashed password, along with the associated salt, is stored in the database.

Ways to build protection against rainbow table attacks: -Salt hashes, using methodology that ensures that equivalent password get different hash functions -Avoid using weak cryptographic schemes, including MD5 and SHA1 -Choosing passwords that are very long (this should not be the default or sole security policy however)

Aparte de las medidas anteriores , es necesario incorporar un Hash Seguro aplicando tecnicas de “salting”. ( agregar información única antes del Hash para complicar la generación de la tabla “arco iris”.

One simple solution to prevent hacking using Rainbow table technique is to use strong hashing algorithms and choose complex passwords. Additionally, using multiple layers of encryption and implementing techniques such as delaying login attempts and locking user accounts after a certain number of unsuccessful attempts can also prevent attacks using Rainbow tables.

Organizations should set aside a particular budget for cyber awareness. This will encompass cyber security training for all staff, aimed at equipping the staff with knowledge on how to identify security threats and ways to deter them. Phishing attacks come in many forms, some common are vishing (voice mail), smishing (sms), spear phishing (messages aimed for specific group of executives), and email phishing (this is most common). The cyber security awareness sessions should be done regularly, and there should be a special platform for sharing cyber security information. This is done even in nation wide level.

Regular assessments, including architectural reviews, must be relentlessly conducted to gauge the ever-changing effectiveness of your anti-phishing and security strategies. As threats morph and mutate, our ability to adapt becomes our most formidable defense. In the realm of IT, change is not just constant; it's the only certainty!

Phishing attacks mainly exploits human vulnerabilities to gain unauthorized access or extract sensitive information. #Kali offers Social Engineering Toolkit (#SET) and Credentials #Harverster Tools for this type of attack.These tools enable attackers to craft convincing phishing campaigns ,manipulating users and gaining sensitive data. #DNS #Protection plays a pivotal role in mitigating phishing attacks. #Cisco #Umbrella (formerly #OpenDNS) , a cloud-delivered security service, uses #DNS filtering to identify and block malicious domains. By analyzing domain requests in real-time, Umbrella prevents users from accessing phishing sites, enhancing overall security. you can also use #Cloudflare #Gateway , #Quad9 , #Akamai Threat Protector and ..

This is the most common way for someone to gain access to your personal details. Ensure the entire business is trained up (and refreshed regularly) on how to spot a phishing attack and what to do when you see one

Phishing is one of the most common type of cyber attacks, "spear phishing" is a targeted form of phishing where an attacker customizes their deceptive communication (such as an email) to a specific individual or organization. Tailored malicious messages are much more effective than generic bulk message. Recommendations: 1. Upgrade to the latest version of your secure email gateway (SEG) 2. Deploy URL filtering (that uses URL proxying and time-of-click analysis), attachment sandboxing, and content disarm and reconstruction (CDR) 3. Implement real-time anti-phishing training 4. Enforce higher-trust authentication 5. Ensure proper desktop and Web gateway security 6. Most important: strengthen internal process controls

Keylogging attacks exploit software vulnerabilities to secretly record keystrokes. In Kali Linux, tools like #Keylogger , #Beelogger and #Metasploit are used for this purpose. However #Antivirues are the best defense for this attack. Behavioral analysis and signature-based detection are common techniques. Behavioral analysis identifies suspicious patterns in user behavior, while signature-based detection relies on known keylogger signatures. Regular updates are essential to enhance the database of signatures and stay ahead of emerging threats. #Kaspersky Endpoint Security Implemented multi-layered approach, including signature-based detection, heuristic analysis, and cloud-assisted technologies to detect and mitigate this attack.

Mi opinión es siempre mantener los discos de un computador cifrado, usar una especie de BitLocker y con eso mantener una buena seguridad.

Keystroke loggers does not always requires the response of a human in order to be introduced into the system. Various methods of keyloggers exist such as in malicious software, hardware-based, memory-based, form grabbing, even acoustic. It requires advance computing knowledge in order for a user to detect this kind of attack. This can be dealt with updated software, use of private computers for sensitive processes like banking, and healthcare. Use of public computers must be for basic surfing and with no input of sensitive and secret information.

Use security key. example: Google Titan, Yubikey, etc. It'll protect your password from keylogging attack (because the hacker only got your password, not your security key) + it's very easy, it's really a no-brainer.

Strategies for preventing keylogging attacks include many of the same defenses against malware more generally. This means educating people (human error causes many breaches) on how to avoid getting malware installed, and to use effective AV technologies. Common sense security practices include keeping software up-to-date with patches, filtering for spam, and training on detecting suspicious messages, links, and downloads. Those with key physical devices at risk of keylogger attacks should also monitor for any unknown hardware devices.

Security is a people problem, as it starts and ends with people. Thus, educate your end users, but not with the same phishing campaign on repeat, that they will learn to hate and eventually ignore. Talk to them about their role in the security of the organization, about risks that are real and how you're equiped to combat those. People tend to react when they are included, you'll find many of the employees having great potential in helping you safeguard the organization. Know your weakesnesses and act accordingly.

Diversify the passwords you use across sites. No one uses the same key to unlock their home and their car. Web applications and domain accounts should follow this same tenant. The loss of password confidentiality due to a breach should not result in the mass compromise of all your accounts.

One of the most common techniques are phishing which might be prevented by employee awareness. Another technique is brute force, which can be prevented by using captcha or account lockout policies. We also saw vulnerable browsers, caches and credentials vault that might also be stolen, these can be mitigated through using EDR, Patch Management, Hardening etc

One of the most easiest ways to find valid credentials for a given organisation is to use the password spraying technique. Take the most common password and try it once against all accounts in the organisation. However, be sure to use common passwords that are common to that organisation. The more accounts an organization has the more chances of finding an account that uses a common password. This is a very noisy attack and can easily be detected by creating a rule that triggers when a single machines is trying to authenticate more than say 50~ accounts..

Why would you crack a password when you can get the password or parts of it for free? Through database leaks access credentials are published or sold regularly on the internet and often darknet forums. Often you can download them or you can use a site like DeHashed to retrieve them without effort in exchange for some money. As people tend to reuse their passwords, adapt only parts such as year or the name of the service they are used for, this is a very efficient way to easily start a password search and limit the possibilities for a directory or brute force attack for a given account. Don't reuse your password. Generate it randomly for every service. Use multi-factor authentication. Be alert for phishing. React fast when it happens.
