1. Malware 

Malware attacks accounted for 27% of all cyber incidents in 2024. And 27% of consumers have stopped using public Wi-Fi to protect online privacy. Malware encompasses a variety of malicious software, including viruses (which attach themselves to legitimate programs), trojans (which masquerade as legitimate software), and spyware (which secretly gathers user information). 

Pros: Cons:
Malware can steal sensitive data, disrupt operations, and provide unauthorized access to attackers. This can lead to data breaches and significant financial losses.  Malware typically requires user action—such as downloading an infected file or clicking a malicious link—to infect a system. Furthermore, most antivirus software can detect and eliminate common malware types, making it easier to defend against them. 

2. Phishing 

Phishing attacks use deceptive emails, messages, or websites to trick users into revealing personal information, such as usernames, passwords, and credit card numbers. These attacks often mimic legitimate entities to appear trustworthy. Over 75% of targeted cyberattacks start with an email in 2024, making phishing a primary vector for cybercrime. 

Pros: Cons:
Phishing can reach a broad audience quickly, making it an effective way for attackers to harvest sensitive information from numerous victims simultaneously.  As phishing techniques become more sophisticated, they are increasingly harder to detect. Attackers may use social engineering tactics to craft highly believable messages, making user vigilance essential. 

3. Ransomware 

Ransomware encrypts files on a victim’s device, rendering them inaccessible, and demands payment (often in cryptocurrency) for the decryption key. 

Pros: Cons:
Successful ransomware attacks can yield significant financial profits for attackers, incentivizing further attacks on businesses and individuals.  Victims may face permanent data loss if backups are not maintained, as recovering encrypted files can be challenging without the decryption key. 

4. Denial-of-Service Attacks 

These attacks overwhelm a service, server, or network by flooding it with excessive traffic, rendering it unavailable to legitimate users. 

Pros: Cons:
DoS attacks are relatively simple to execute, especially with the availability of botnets that attackers can rent to launch large-scale assaults.  While they can disrupt operations temporarily, many organizations can mitigate DoS attacks through robust security measures, such as traffic filtering and rate limiting. 

5. Man-in-the-Middle Attacks 

In these attacks, an intruder intercepts communication between two parties (such as a user and a website) to steal data or inject malicious content. 

Pros: Cons:
MitM attacks effectively capture sensitive information like login credentials and payment details, making them highly lucrative for cybercriminals.  Executing a successful MitM attack typically requires sophisticated tools and techniques, making it less common than other threats. 

6. SQL Injection 

This attack exploits vulnerabilities in an application’s software by inserting malicious SQL code into input fields, allowing attackers to manipulate database queries. 

Pros: Cons:
SQL injection can lead to unauthorized access to sensitive data, such as user accounts and financial records. Secure coding practices, such as input validation and parameterized queries, can effectively prevent SQL injection attacks. 

7. Zero-Day Exploits 

These exploits target unpatched vulnerabilities in software immediately after discovery, before the vendor has had a chance to issue a fix. 

Pros: Cons:
Zero-day exploits are particularly dangerous as they can be highly effective and stealthy, giving attackers a window of opportunity to cause significant harm.  Regular software updates and vulnerability management practices can help mitigate the risk of zero-day attacks. 

8. Credential Stuffing 

Credential stuffing involves using stolen username and password combinations to gain unauthorized access to user accounts, relying on the common practice of password reuse. 

Pros: Cons:
This attack can quickly compromise numerous accounts if users have not implemented unique passwords for different sites.  Implementing multi-factor authentication can significantly reduce the effectiveness of credential-stuffing attacks, making it more difficult for attackers to gain access. 

9. Social Engineering 

Social engineering involves manipulating individuals into divulging confidential information by exploiting psychological triggers, such as fear, urgency, or trust. 

Pros: Cons:
These attacks can bypass technical security measures, as they target the human security element. Organizations can reduce the effectiveness of social engineering attacks through comprehensive awareness training for employees. 

10. IoT Vulnerabilities 

The rise of Internet of Things (IoT) devices introduces new security risks, as many lack robust security features and can be easily compromised. 

Pros: Cons:
IoT vulnerabilities are often overlooked, providing attackers with easy entry points into secure networks.  Many IoT devices may not support updates, making them persistently vulnerable to attacks. 

11. Supply Chain Attacks 

These attacks target third-party vendors or partners to compromise an organization’s security. Attackers may infiltrate a trusted vendor to access the networks of larger organizations. 

Pros: Cons:
Supply chain attacks can impact numerous organizations simultaneously, making them highly effective.  Executing such attacks requires careful planning and execution, making them complex but potentially rewarding for attackers. 

12. Insider Threats 

Insider threats involve security risks within the organization, typically from disgruntled employees or contractors who misuse their access. 

Pros: Cons:
Insider threats can be particularly damaging because they are often difficult to detect and can lead to significant data breaches.  Organizations can mitigate the risk of insider threats through robust monitoring, access controls, and employee engagement strategies. 

13. Cryptojacking 

Cryptojacking involves the unauthorized use of someone else’s computer or device to mine cryptocurrency without the user’s knowledge. 

Pros: Cons:
This attack is often invisible to users until they notice degraded system performance, making it a stealthy way for attackers to profit. Unusual resource usage patterns can help detect cryptojacking, prompting users to take action to secure their devices. 

14. Advanced Persistent Threats (APTs) 

APTs involve prolonged, targeted cyberattacks where an intruder gains access to a network and remains undetected for an extended period. 

Pros: Cons:
These attacks are highly stealthy and sophisticated, often aimed at stealing sensitive information or intellectual property.  APTs require significant resources and expertise to execute, making them more challenging for attackers to carry out than other types of attacks. 

15. Worms 

Worms are self-replicating malware that spreads across networks without requiring user action. 

Pros: Cons:
Worms can quickly infect numerous systems, causing widespread damage in a short amount of time.  Most modern security systems can detect and prevent worm infections, making them easier to defend against than other threats.
