What are Cyber Attacks?

A cyber attack is a malicious attempt to disrupt, damage, or gain unauthorized access to computer systems, networks, or devices.

Such attacks can target individuals, businesses, or governments with the intent to steal sensitive data, extort money, or cause widespread disruption.

Cyber attacks are constantly changing therefore, constant information must be received and preparedness should be maintained.

Types of Cyber Attacks

1. Malware Attacks

Malware is malicious software that has the intent of breaching and causing harm to a system. These include:

Viruses: These attach themselves to clean files and spread within a system.

Ransomware: This locks the users out of their systems or data until the ransom is paid.

Spyware: These monitor the user activity secretly and obtain sensitive information from them.

Effects:

Data loss, financial damage, and system downtime.

Protection:

Use of antivirus software, keeping the system updated, and avoiding suspicious downloads.

2. Phishing

Phishing is a scam where it takes people into tricking them to authenticate with some authentic website or take the malware from that site which asks for passwords or credit card numbers, etc. It usually happens by spam emails or websites.

Effect:

Identity theft, loss of money, and compromised accounts.

Protection

Be aware of unsolicited emails; ensure sender addresses; and use multi-factor authentication.

3. Denial-of-Service (DoS) and Distributed Denial-of-Service (DDoS) Attacks

These attacks swamp a system, server, or network with high volumes of traffic, making the system unavailable to users. During a DDoS attack, several compromised systems are used for the attack.

Impact

These attacks cause disordered services, revenue loss, and reputational damage.

How to prevent such attacks

You can prevent the attacks by enabling traffic filtering, using a CDN, and observing network traffic.

4. Man-in-the-Middle (MitM) Attacks

In MitM attacks, a hacker interferes with communications between two parties to steal information or inject harmful content.

Impact:

Data breaches, unauthorized transactions, and compromised privacy.

Prevention:

Use encryption (HTTPS), avoid public Wi-Fi for sensitive transactions, and employ VPNs.

5. SQL Injection

This attack involves injecting malicious SQL code into databases to allow hackers to access, modify, or delete data.

Impact:

Data theft, loss of customer trust, and legal consequences.

Prevention:

Use parameterized queries, validate user inputs, and regularly test for vulnerabilities.

6. Zero-Day Exploits

A zero-day exploit strikes against a previously unknown vulnerability in software or hardware, providing developers with zero days to address the vulnerability before it is exploited.

Impact

Serious breaches of data, system compromise, and monetary loss.

Prevention

Up-to-date software, monitoring for unusual activity, and intrusion detection systems.

7. Social Engineering

Social engineering manipulates individuals into surrendering confidential information. Common ploys are through pretexting, baiting, and tailgating.

Impact

Unauthorized access, breaches of data, and fraud committed with money.

Prevention

Educate employees, implement strict access controls, and verify identities.

8. Insider Threats

Insider threats involve malicious or negligent actions by employees or contractors that compromise security.

Impact:

Data leaks, financial losses, and reputational damage.

Prevention:

Conduct background checks, monitor user activity, and enforce strict access policies.
