Remote timing attacks

Vulnerability Assessment as a Service (VAaaS)

Tests systems and applications for vulnerabilities to address weaknesses.

Remote timing attacks are a type of cyber attack where an attacker can deduce sensitive information by analyzing the time taken by a system to respond to certain requests. In these attacks, an attacker can exploit the time it takes for a server or a device to respond to certain queries, such as authentication requests or cryptographic operations, to extract information about the system’s internal state or data. By carefully measuring the response time, an attacker can infer sensitive information such as passwords, encryption keys, or other secret information. These attacks are often carried out remotely and can be difficult to detect and prevent. Remote timing attacks are a serious threat to the security of networks and systems, and require careful mitigation strategies to prevent their exploitation.

Example of vulnerable code on different programming languages:


in PHP:

				
					<?php
function checkPassword($password) {
    $hash = md5($password);
    $dbhash = lookupHashFromDatabase();
    if ($hash == $dbhash) {
        return true;
    } else {
        return false;
    }
}
?>

				
			


This PHP code checks whether a given password matches the hashed password stored in the database. An attacker can launch a remote timing attack by repeatedly sending requests with different passwords and measuring the time it takes for the server to respond. If the server takes longer to respond when the password is closer to the correct password, the attacker can use this information to guess the correct password.

• in Python:

				
					import time
import hmac

def check_mac(message, mac, key):
    expected_mac = hmac.new(key, message, digestmod='sha256').hexdigest()
    if expected_mac == mac:
        return True
    else:
        return False

start_time = time.time()
check_mac('secret message', 'bad mac', 'bad key')
end_time = time.time()
elapsed_time = end_time - start_time

print('Elapsed time:', elapsed_time)

				
			


This Python code checks whether a given message has been authenticated using a message authentication code (MAC) generated using a secret key. An attacker can launch a remote timing attack by repeatedly calling the check_mac function with different messages and measuring the time it takes for the function to return. If the function takes longer to return when the message is closer to the correct message, the attacker can use this information to guess the correct message.

• in Java:

				
					public boolean authenticate(String inputUsername, String inputPassword) {
    long startTime = System.nanoTime();

    // check if inputUsername and inputPassword match database
    boolean result = checkDatabase(inputUsername, inputPassword);

    long endTime = System.nanoTime();

    // log the time taken for authentication
    logger.log(Level.INFO, "Authentication took " + (endTime - startTime) + " nanoseconds");

    return result;
}

				
			


In this Java example, the code measures the time taken for authentication and logs it using the logger object. However, an attacker can use this timing information to determine whether a username or password is correct by measuring the time taken for authentication.

Examples of exploitation Remote timing attacks

Password cracking:

An attacker can use remote timing attacks to guess a user’s password by observing how long it takes for a system to respond to a login request. By making repeated login attempts with different passwords, the attacker can determine which password is correct based on how long it takes the system to respond.

Cryptographic attacks:

Remote timing attacks can be used to crack cryptographic keys by measuring the time it takes to perform encryption or decryption operations. By analyzing the timing data, an attacker can determine the key used to encrypt or decrypt a message.

Network scanning:

An attacker can use remote timing attacks to scan a network for open ports or other vulnerabilities. By sending a series of requests to different ports and analyzing the response times, the attacker can determine which ports are open and vulnerable to attack.

Side-channel attacks:

Remote timing attacks can also be used as a side-channel attack to gain access to sensitive information such as cryptographic keys, passwords, or other data. By analyzing the timing data of a system’s responses, an attacker can infer information about the system’s internal state and use this information to launch further attacks.

Privilege escalation techniques for Remote timing attacks

Time-based Blind SQL Injection:

This is a technique where an attacker can inject malicious code into a vulnerable application, which in turn sends a query to the database. The attacker can then measure the time it takes for the database to respond, allowing them to extract information from the database.

Remote Timing Side Channel Attack:

This technique involves exploiting the timing differences between different system components to extract sensitive information. For example, an attacker could measure the time it takes for a response to be returned from a server, allowing them to deduce which encryption algorithm is being used and potentially extract sensitive data.

Remote Timing Attack on Cryptography:

This technique involves exploiting timing differences in cryptographic algorithms to extract sensitive information. For example, an attacker could measure the time it takes to decrypt a message, allowing them to deduce the key used in the encryption process.

Remote Timing Attack on Authentication:

This technique involves exploiting timing differences in authentication protocols to extract sensitive information. For example, an attacker could measure the time it takes for a server to respond to a login request, allowing them to deduce whether a valid username was entered.

Remote Timing Attack on Authorization:

This technique involves exploiting timing differences in authorization protocols to gain unauthorized access to a system. For example, an attacker could measure the time it takes for a server to respond to an access request, allowing them to deduce whether the request was granted or denied.
