What is Hacking?
Hacking is the term for the unlawful use, manipulation, or exploitation of networks, data, or computer systems, usually for malevolent or personal gain. It includes a broad range of tasks, including as finding and taking advantage of flaws as well as breaking into secure systems.
Depending on the purpose and legality of the actions involved, hacking may be considered ethical when done with authorization, unlawful, or somewhere in between.
Types of Hacking Attacks?
- Phishing Attacks
Phishing attacks entail tricking people into divulging private information, including usernames, passwords, or bank account information, by using false emails, messages, or websites that impersonate reliable organizations.
2. Malware Attacks
Attackers can obtain unauthorized access, steal data, or interfere with operations by using malicious software, such as viruses, worms, and Trojan horses, to penetrate and corrupt systems.
3. Denial of Service (DoS) Attacks
Attacks known as denial of service overload a target server or network with a large amount of traffic, making it impossible for authorized users to access services and taxing its resources.
4. Distributed Denial of Service (DDoS) Attacks
DDoS assaults use a number of hacked devices, frequently arranged into botnets, to flood a target with traffic and make it even harder to stop and recover from the attack.
5. SQL Injection Attacks
By manipulating input fields on websites to insert malicious SQL code, SQL injection attacks have the ability to allow unauthorized access to databases and compromise or exfiltrate sensitive data.
6. Man-in-the-Middle (MitM) Attacks
MitM attacks involve the interception and possible modification of communication between two parties by an attacker without their knowledge, with the potential to obtain sensitive information that is being shared.
7. Social Engineering Attacks
Social engineering attacks use psychological manipulation to trick people into divulging private information or doing actions that jeopardize security.
8. Brute Force Attacks
Brute force assaults, which are frequently used to obtain unwanted access to accounts or systems, entail continuously attempting every possible combination of username and password until the right one is found.
9. Zero-Day Exploits
Because there are no patches or fixes available when they are exploited, zero-day exploits focus on software or hardware vulnerabilities that the vendor is unaware of. This makes them especially dangerous.
10. Ransomware Attacks
Attacks using ransomware encrypt a victim’s data, making it unusable until the attacker is paid a ransom for a decryption key. This frequently results in major disruption and monetary loss for both individuals and businesses.
Difference Between Hacking and Ethical Hacking
|1.||Intent and Legality||The goal of hacking is to obtain unauthorized access, steal data, or interfere with systems by the use of unauthorized and frequently unlawful actions.||Legal and carried out with express consent, ethical hacking aims to improve system security by finding and addressing security flaws.|
|2.||Authorization||Because hacking is done without the target’s consent, it is illegal.||Ethical hackers are permitted to evaluate and test system security with legal authorization.|
|3.||Motivation||Malicious intent, financial gain, or personal gain are the usual motivations behind hacking.||The goal of improving cybersecurity, safeguarding data, and fortifying an organization’s defenses drives ethical hacking.|
|4.||Methods and Tools||Hackers can be disruptive or dangerous, and they employ a range of tools and strategies to take advantage of weaknesses.||When identifying vulnerabilities, ethical hackers employ comparable methods and resources without causing harm; their activities are well-recorded and non-destructive.|
|5.||Outcome||Data leaks, financial loss, and legal repercussions for the hacker are all possible outcomes of hacking.||Better security, lower risks, and a safer online environment for people and businesses are the outcomes of ethical hacking.|
