Final answer:
An active attack on a cryptographic system involves actively interfering with the system to gain unauthorized access or modify data. A passive attack involves passively monitoring the communication channels or collecting information without altering data. Hackers use tactics like phishing and malware to steal data and can be reduced through cybersecurity measures.
Step-by-step explanation:
An active attack on a cryptographic system is when a hacker actively interferes with the system to gain unauthorized access or modify the data being transmitted. This type of attack involves the hacker actively manipulating or intercepting the communication channels to achieve their objectives.
A passive attack on a cryptographic system is when a hacker passively monitors the communication channels or collects information without altering or tampering with the data. This type of attack involves the hacker eavesdropping on the communication to gather sensitive information.
Tactics used by hackers can include techniques like phishing, malware, brute-force attacks, or exploitation of vulnerabilities in software. Hackers may steal various types of data, such as personal information, financial data, or intellectual property. The stolen data can be used for various purposes, including identity theft, financial fraud, or selling on underground markets.
Hacking can be reduced or mitigated through various measures, including strong passwords, two-factor authentication, regular software updates, encryption, and employee training on cybersecurity best practices.
An active attack on a cryptographic system involves altering or disrupting operations, such as by modifying data, while a passive attack involves eavesdropping without data alteration. Hackers use various tactics like phishing and malware to steal data that they can sell or use maliciously. Employing security software and best practices can help reduce the occurrence of such attacks.
An active attack on a cryptographic system is a type of interference where an attacker attempts to alter system resources or affect the operation to achieve a specific goal. This could involve modifying transmitted data, injecting malicious data, or disrupting the normal functioning of a system. Examples of active attacks include man-in-the-middle, replay attacks, and masquerading.
In contrast, a passive attack on a cryptographic system is one where the attacker attempts to gain unauthorized access to data by eavesdropping on communications without altering the content. The goal is to obtain sensitive information without detection. Examples of passive attacks are traffic analysis and interception of communications.
Hackers use a variety of tactics to exploit weaknesses in systems, such as phishing, malware, ransomware, and SQL injection. They often steal sensitive personal information, financial data, intellectual property, and login credentials. This stolen information can be sold on the dark web, used to commit fraud, or leveraged for ransom.
The success rate of hackers is hard to quantify due to the vast number of unreported incidents; however, successful breaches can have devastating consequences for individuals and organizations alike. To stop or reduce hacking, one can use antivirus software, firewalls, regular software updates, and education on cybersecurity best practices.
