Understanding Cybersecurity Threats: Types and Sources
Common Sources of Cybersecurity Threats
Nation States
Nation states pose significant cybersecurity threats by launching cyber attacks aimed at destabilizing local companies and institutions. These attacks can disrupt communications and cause widespread disorder.
Terrorist Organizations
Terrorist entities conduct cyber attacks against critical infrastructure to undermine national security, disrupt economies, and inflict harm on citizens.
Criminal Groups
Organized hacker groups exploit vulnerabilities by employing tactics such as phishing, spam, and malware attacks to gain illicit financial benefits through identity theft, extortion, or online scams.
Individual Hackers
Individual hackers utilize a variety of attack techniques for personal gain, revenge, or political motives. They often create new threats to enhance their criminal capabilities.
Malicious Insiders
Malicious insiders—such as employees, contractors, or partners—abuse their legitimate access to company resources, leading to data breaches or system damage for personal gain.
Types of Cybersecurity Threats
Malware Attacks
Malware, short for malicious software, encompasses various types of threats including viruses, worms, trojans, spyware, ransomware, and more. It infiltrates systems often through untrusted links, collecting sensitive data and potentially causing extensive damage.
Key Malware Types
- Viruses: Malicious code that attaches itself to applications, enabling execution when the application runs.
- Worms: Software that exploits vulnerabilities to infiltrate systems and may initiate distributed denial-of-service (DDoS) attacks.
- Trojans: Malicious programs disguised as legitimate software, allowing attackers to control infected devices once downloaded.
- Ransomware: Prevents users from accessing their systems until a ransom is paid, often without ensuring restoration of access.
- Bluetooth and Cryptojacking Attacks: Utilize unauthorized access to drain resources or mine cryptocurrency without consent.
- Spyware and Adware: Gathers user data or displays targeted ads, potentially compromising privacy.
- Rootkits: Provides remote administrative access, allowing complete control over a compromised system.
Social Engineering Attacks
Social engineering manipulates individuals into compromising security protocols by tricking them into divulging sensitive information or unwittingly installing malware.
Primary Social Engineering Techniques
- Baiting: Luring victims into providing sensitive data with enticing offers.
- Pretexting: Impersonating authority figures to extract confidential information.
- Phishing, Vishing, and Smishing: Utilizing fake emails, voice calls, or SMS messages to harvest personal data.
- Piggybacking and Tailgating: Gaining unauthorized physical access through the assistance or negligence of authorized personnel.
Supply Chain Attacks
Targeting software vendors, supply chain attacks introduce malware during the development process, exploiting vulnerabilities in build and update protocols. This type of attack can lead to widespread distribution of infected applications.
Man-in-the-Middle Attack (MitM)
MitM attacks involve intercepting communications to eavesdrop, steal data, or impersonate either party involved. Techniques include Wi-Fi eavesdropping, email hijacking, and DNS spoofing.
Denial-of-Service (DoS) Attacks
DoS attacks overwhelm systems with excessive traffic, rendering services unavailable. A more severe form involves multiple devices, known as Distributed Denial-of-Service (DDoS) attacks.
DoS Attack Methods
- HTTP Flood: Uses legitimate-seeming requests to overload web servers.
- SYN Flood: Exploits TCP connection requests to consume server resources.
- UDP Flood: Floods targeted systems with UDP packets to exhaust resources.
- ICMP Flood: Sends excessive ICMP requests to slow down server response times.
- NTP Amplification: Leverages publicly accessible NTP servers to amplify attack volume.
Injection Attacks
Injection attacks exploit application vulnerabilities to insert malicious inputs, potentially compromising databases or executing unwanted commands.
Common Injection Types
- SQL Injection: Manipulates database queries through user inputs, leading to unauthorized data access.
- Cross-Site Scripting (XSS): Executes harmful scripts in a target’s browser, facilitating session hijacking or redirection to malicious sites.
