3. Spyware - Spyware secretly monitors and collects sensitive information from infected devices, including keystrokes, browsing habits, and personal data, compromising user privacy and security.

4. Adware - Adware displays unwanted advertisements and pop-ups on infected devices, disrupting user experience and potentially exposing them to further security risks.

5. Worms - Worms self-replicate and spread across networks without user intervention, exploiting vulnerabilities to infect multiple devices rapidly.

2. Denial-of-Service (DoS) Attacks

Denial-of-Service (DoS) cyber-attacks aim to disrupt the availability of online services by overwhelming a target system with a flood of traffic, rendering it inaccessible to legitimate users. Attackers often use botnets, networks of compromised devices, to orchestrate massive volumes of traffic directed at the target. Variants such as Distributed Denial-of-Service (DDoS) attacks amplify the impact by coordinating attacks from multiple sources simultaneously. 

DoS attacks can exploit vulnerabilities in network infrastructure, web servers, or applications, exploiting weaknesses in protocols like TCP/IP or HTTP. The impact of a successful DoS attack can range from temporary inconvenience to significant financial losses and reputational damage for businesses. 

3. Phishing 

Phishing cyber threats involve deceptive tactics, such as fraudulent emails, messages, or websites, to trick individuals into divulging sensitive information such as passwords, financial details, or personal data. Cyber attackers often impersonate legitimate entities, such as banks, social media platforms, or government agencies, to gain victims' trust and encourage them to click on malicious links or provide confidential information. 

Phishing attacks exploit human vulnerabilities, relying on curiosity, urgency, or fear to manipulate victims into taking action. 

Types Of Phishing 
1. Spear Phishing - It targets specific individuals or organizations, often using personalized messages to increase their effectiveness.
2. Whaling - Whaling attacks specifically targets high-profile individuals, such as executives or senior management, to gain access to sensitive information or funds.
3. Vishing -  Vishing attacks is conducted over voice calls, where attackers impersonate legitimate entities to trick victims into revealing personal or financial information.
4. SMiShing - SMiShing threats takes place via SMS or text messages, typically containing malicious links or prompts to elicit sensitive information from recipients.

4. Spoofing 

Spoofing attacks constitute a deceptive practice in which attackers falsify data or identities to mislead victims and gain illicit access to systems or sensitive information. These attacks encompass various forms, including IP spoofing, email spoofing, and website spoofing, each exploiting vulnerabilities in communication protocols. 

Types Of Spoofing 
1. IP spoofing  - It manipulates IP addresses to conceal the source of network traffic, facilitating unauthorized access or launching denial-of-service attacks. 

2. Email spoofing -  Email spoofing involves forging email headers to impersonate legitimate senders, tricking recipients into divulging confidential information or downloading malware. 

3. Website spoofing - It creates counterfeit websites resembling legitimate ones, aiming to deceive users into entering personal or financial details. 

By exploiting flaws in trust mechanisms and employing social engineering tactics, spoofing attacks undermine cybersecurity defenses. 

5. Identity-Based Attacks

Identity-based cyber attacks involve exploiting compromised or stolen credentials to gain unauthorized access to systems, networks, or sensitive data. These attacks target individuals or organizations, aiming to impersonate legitimate users or entities and bypass authentication measures. 

Identity-based attacks include credential stuffing, password spraying, and brute-force attacks, which exploit weak or reused passwords to compromise accounts. Cybercriminals may also conduct phishing campaigns to harvest login credentials or trick users into divulging sensitive information. These attacks pose significant risks to data confidentiality, integrity, and availability, potentially leading to data breaches, financial losses, or reputational damage. 

Mitigating these threats requires implementing robust authentication mechanisms, such as multi-factor authentication and password policies, to strengthen access controls and verify users' identities securely. 

6. Code Injection Attacks

Code injection attacks involve inserting malicious code into vulnerable software applications, exploiting vulnerabilities to execute unauthorized commands or manipulate system behavior. 

Types Of Code Injection Threats
Credential Harvesting - Cybercriminals makes use of user credentials for gathering login credentials through deceptive tactics such as phishing emails or fake login pages.

Credential Stuffing - Credential stuffing attacks capitalize on the tendency for individuals to reuse the same login credentials across various accounts, enabling attackers to potentially access unrelated accounts by possessing the credentials for just one account.

Password Spraying - In a password spraying attack, a threat actor employs a common password across multiple accounts within the same application to evade the typical account lockouts triggered by brute force attacks, where numerous passwords are attempted on a single account.

Pass-the-Hash Attack - Pass the hash is an attack method where an attacker steals a "hashed" user credential and employs it to establish a fresh user session within the same network, bypassing the need to ascertain or decipher the password for system access. 

Man-in-the-Middle (MITM) Attack - A man-in-the-middle attack involves a cyber assailant intercepting communications between two parties to gather personal data, passwords, or financial information, as well as persuading the victim to perform actions like altering login credentials, conducting transactions, or transferring funds.

7. Supply Chain Attacks

Supply chain attacks occur when cybercriminals infiltrate an organization's systems through vulnerabilities in its supply chain partners or third-party vendors. These attacks exploit trust relationships, allowing attackers to compromise systems and networks indirectly, often with devastating consequences. 

By targeting weaker links in the supply chain, attackers can gain access to valuable data, disrupt operations, or distribute malware to a wider network of targets. Mitigating supply chain attacks requires comprehensive risk assessment, vetting of third-party vendors, and implementing robust security measures to detect and prevent unauthorized access or data breaches. 

8. Insider Threats

Insider threats refer to the risks posed by individuals within an organization who have privileged access to sensitive information and systems. These insiders may intentionally or unintentionally misuse their access to steal data, sabotage systems, or compromise security. 

Insider threats can manifest in various forms, including disgruntled employees, negligent workers, or malicious insiders recruited by external actors. Mitigating insider threats requires implementing strict access controls, monitoring user activities, and conducting regular security awareness training to educate employees about security best practices and the consequences of insider threats. 

9. DNS Tunneling

DNS tunneling is a covert communication method that uses DNS protocol to bypass security controls and exfiltrate data from networks. It involves embedding data within DNS queries and responses, allowing attackers to transmit information disguised as legitimate DNS traffic. DNS tunneling can be used to circumvent firewalls, evade detection, and establish unauthorized communication channels with external servers. 

It requires advanced network monitoring and analysis tools capable of identifying abnormal DNS traffic patterns and scrutinizing DNS requests for suspicious payloads. The organizations must implement robust DNS security measures, including DNS filtering, threat intelligence, and anomaly detection, to mitigate the risks posed by DNS tunneling attacks and protect their networks from unauthorized data exfiltration.
