An Overview Of Authentication Attack Evasion Methods

By Tom Seest

How to Evade Authentication Attacks?

In the digital realm, the security of our online identities hinges on the robustness of authentication processes. When these processes falter, the door opens to password compromise attacks. The likelihood of such attacks succeeding is a function of password complexity and the attacker’s ability to reach the user. These attacks don’t just breach accounts; they grant attackers the same privileges as the user, posing significant risks.

How to Evade Session Hijacking Attacks?

Imagine you’re sipping coffee at a café using public Wi-Fi. Little do you know, this setting is ripe for session hijacking attacks. To shield yourself, employ a VPN. It’s like a digital cloak, rendering your online presence invisible and encrypting your data. Additionally, arm your system with security software to thwart malware and viruses. Attackers in session hijacking sniff out session IDs to impersonate users, often using malicious links. The consequences? They could drain bank accounts or hold personal data for ransom. Remember, HTTP is a favored playground for these attackers due to its session cookies.

When using public Wi-Fi, it is important to protect your identity by installing a virtual private network (VPN). This will conceal your IP address and ensure your online activities remain private. Additionally, using security software can help prevent malware and viruses from attacking your system. One common type of attack is session hijacking, where an attacker exploits weak security points in web servers to access a user’s session ID and gain unauthorized access. They may then send the victim a malicious link to carry out their instructions. This can result in theft of money or personal information, or ransom demands. Attackers typically target large networks and prefer protocols like HTTP that allow them to maintain control over the user’s session. While session hijacking may not be as prevalent as spyware or rootkits, it is still a common cyber-attack.

How to Evade Reverse Brute Force Attacks?

Reverse brute force attacks turn the conventional approach on its head. Instead of starting with a username, these attacks begin with common passwords, aiming to guess the right username. They’re time-intensive and often automated through bots or credential stuffing. The latter exploits reused credentials across multiple accounts. Dictionary attacks, another variant, use common words and phrases but are slow and less effective.

Reverse brute force attacks involve hackers attempting to bypass authentication checks by using the brute force principle. These attacks can be quite time-consuming. Typically, the attacker will start with a common password and try to guess the user’s username. They may use dictionary words and phrases in their attempts. To automate the process, the malicious party may use applications or programs that can guess password combinations and session IDs. The most commonly used tool for brute force attacks is a bot. Hackers often have a list of stolen credentials and will use the bot to systematically attack websites using these credentials. Another method is called credential stuffing, where the attacker takes advantage of repeatedly used usernames and passwords to gain access to multiple accounts. This technique, although older than modern brute force attacks, is still relevant because people are not following security best practices. Dictionary attacks, on the other hand, involve using a dictionary of common words, phrases, and passwords to find a password. While this method can help a hacker find the most commonly used passwords, it is slow and not very successful.

In session cookie attacks, attackers exploit the data exchange between servers and nodes. They might create fake sessions to deceive users into logging into compromised sites. These attacks are prevalent on public networks, where hackers can easily intercept data. To counter this, use temporary session cookies that expire after a session. However, this can impact user experience. Attackers can also inject malicious scripts into trusted websites to hijack sessions, gaining access to passwords and emails.

Attackers may exploit the Session cookie to bypass authentication attempts by intercepting traffic and data exchanged between web servers and nodes. They can also create deceptive sessions to deceive users into logging into an insecure site. These attacks are particularly prevalent in public Wi-Fi networks, as hackers can easily view all network traffic by using a packet sniffer. Another method of attack, known as “session side jacking,” involves manipulating network traffic to steal a session cookie. While most websites use SSL/TLS encryption to prevent this type of attack, some do not. Attackers can also steal session cookies by obtaining a copy of the victim’s cookie, granting them access to the victim’s account. Once they have the cookie, they can make unauthorized transactions or alter user settings on the victim’s device. One effective measure to prevent this attack is to make the session cookie temporary, expiring after one session or when the user logs out. However, this approach may negatively impact the user experience by limiting the duration of the session cookie. Additionally, a hacker can insert a malicious script into a trusted website and use the session cookie to gain access to the victim’s account. Once they have access, they can view passwords, read emails, and perform unauthorized actions with the victim’s account permissions.

How to Evade Man-In-The-Middle Attacks?

Man-in-the-Middle (MITM) attacks are digital eavesdropping. Attackers intercept data on public networks, masquerading as the victim. They might use malware or phishing to execute these attacks. To safeguard against MITM attacks, encryption is key. It’s a digital fortress, protecting your login credentials and financial data from prying eyes. Emails, often unencrypted, are particularly vulnerable to MITM attacks.

Man-in-the-Middle (MITM) attacks are a common tactic employed by cybercriminals to intercept sensitive data. These attacks often occur on public networks with no security measures in place, making it easy for attackers to impersonate the victim and intercept their information. LANs and Wi-Fi networks are particularly vulnerable to these attacks. Malware designed to monitor internet traffic and phishing scams are some of the methods used to carry out these attacks. MITM attacks can take various forms, such as hijacking, where the attacker takes control of an email account or website, or SSL phishing, which involves masquerading as a trusted sender. Eavesdropping, which involves intercepting data transmitted between users, is another common method used in these attacks. To protect against MITM attacks, network administrators should implement centralized authentication and resource visibility controls. While these attacks are difficult to detect, following best practices such as using encryption and data encryption can help safeguard against them. Hackers often use MITM attacks to target websites and emails, as these are often not encrypted and thus easier to compromise. By spoofing emails and stealing login credentials, attackers can gain access to sensitive information. It is crucial to use encryption to protect against MITM attacks and maintain information security.

How to Evade Session Re-Use Attacks?

In session re-use attacks, hackers exploit session IDs from logged-out users. To prevent this, developers can use a salting hash, creating a one-time authentication barrier. Implementing a session expiration timeout is also crucial. It limits the window of opportunity for a hijacked session. Additionally, using a secure session manager to generate secure cookies can prevent attackers from reusing your credentials.

Session re-use authentication attacks occur when a hacker obtains the session ID of a logged-out user. To prevent these attacks, developers often use a salting hash of the session ID, which also provides the benefit of one-time authentication. Web applications can further protect against these attacks by using JavaScript code on the login page to track the time since the page was loaded and when the session ID was granted. This allows the application to alert the user when the maximum login time has passed and force a session ID renewal. Furthermore, this method prevents session fixation attacks. To enhance security, it is important to implement a session expiration timeout. A shorter timeout reduces the window of opportunity for a hijacked session to be used. The session timeout should be adjusted based on the purpose of the web application, as a longer timeout can make it more vulnerable to session-based attacks. To prevent session fixation, a secure session manager should be utilized. This tool generates secure cookies that prevent attackers from using stolen credentials. This ensures that only authorized users have access to the information on the web application.
