- Present Day: Cyber attacks are increasingly sophisticated, targeting supply chains, financial institutions, and national security.
This advancement is not just about new threats but also involves the changing dynamics of the cyber risk landscape. It includes how threat actors evolve alongside technological advancements that pose new risks and offer new defenses.
What are Major Sources of Cyber Threats?
Cyber threats originate from various sources, including amateur hackers known as 'Script Kiddies,' politically motivated 'Hacktivists,' 'Advanced Persistent Threats (APTs),' 'Organized Crime Groups,' 'Insiders' with access to sensitive information, 'Terrorist Groups' seeking to disrupt, and 'Corporate Spies' aiming to steal trade secrets.
- Terrorist Groups: Utilizing cyber tactics, terrorists aim to disrupt national security, damage critical infrastructure, or cause mass casualties. Their cyber activities are an extension of their broader goals.
- Advanced Persistent Threats (APTs): Highly skilled and well-funded, often backed by nation-states. They aim to gain unauthorized access over extended periods, often targeting crucial infrastructure or sensitive information.
- Criminal Organizations: These groups use cyber attacks for financial gain, employing phishing, ransomware, and identity theft. Their operations are often global and well-organized.
- Malicious Insiders: Malicious insiders include an organization's employees or associates who misuse their access to systems for personal gain or to harm the organization. These insider threats include stealing confidential information or sabotaging IT systems.
- Competitors: Businesses may engage in cyber espionage to steal trade secrets or disrupt the operations of their rivals. This corporate espionage is a growing concern in the hyper-competitive global market.
- Hackers/Hacktivists: Often driven by personal challenges, political activism, or financial gain, hackers employ various techniques to breach security systems. These culprits range from amateurs to highly skilled professionals and may operate independently or in groups.
- Script Kiddies: Young, less skilled individuals wanting bragging rights might use pre-existing malicious software but aren't a high threat.
The primary origins of digital risks extend across spectrums of threat sources. These include varieties of systemic and technological factors like software vulnerabilities and supply chain risks. An organization must address both direct and indirect contributors to the risk landscape.
What are Types of Cyber Threats?
- Malware Attacks: Malware, short for malicious software, includes a range of harmful programs like viruses, worms, trojans, and ransomware. These programs infiltrate systems through deceptive links or downloads to collect sensitive data, disrupt operations, or even destroy data.
- Social Engineering Attacks: This category involves manipulating individuals into unintentionally compromising security. Techniques like phishing, pretexting, and baiting trick users into revealing sensitive information or installing malware. Phishing uses deceptive emails to masquerade as legitimate requests from trusted sources.
- Supply Chain Attacks: These attacks target software developers and vendors, infecting legitimate applications and distributing malware through compromised supply chains. Attackers look for vulnerabilities in network protocols, server infrastructure, and coding techniques to execute these attacks, which are particularly dangerous as they involve trusted software.
- Man-in-the-Middle (MitM) Attacks: In these attacks, an intruder intercepts and possibly alters the communication between two parties. Common examples of MitM include Wi-Fi eavesdropping, where attackers set up fake Wi-Fi networks to steal data, and email hijacking, where attackers spoof a legitimate email address.
- Denial-of-Service (DoS) Attacks: These attacks overload a target system with traffic, rendering it unable to function normally. A variant involving multiple devices, DDoS attacks can use techniques like HTTP floods, SYN floods, and ICMP floods to disrupt services.
- Injection Attacks: These attacks exploit online vulnerabilities in applications to insert malicious code. SQL injection, code injection, and Cross-Site Scripting (XSS) are common injection attacks where attackers manipulate input fields or scripts to gain unauthorized access or retrieve sensitive data.
The broad spectrum of online security threats vary widely in form and intent. These range from forms of digital security risks such as targeted espionage and financial theft to variants of cyber attacks causing widespread disruption and damage to IT infrastructure.
