Corporate Espionage, Business Disruption, or Financial Gain. Whatever the motivation, cybersecurity threats have become pervasive and continue to upend every facet of the digital realm.
What is a Threat in Cybersecurity?
A cybersecurity threat is a malicious and deliberate attack by an individual or organization to gain unauthorized access to another individual’s or organization’s network to damage, disrupt, or steal IT assets, computer networks, intellectual property, or any other form of sensitive data.
Types of Cybersecurity Threats
While the types of cyber threats continue to grow, there are some of the most prevalent cyber threats that present-day organizations need to know about. The top 10 cyber security threats are as follows:
Malware attacks are the most common cyber security threats. Malware is malicious software, including spyware, ransomware, viruses, and worms, which gets installed into the system when the user clicks a dangerous link or email. Once inside the strategy, malware can block access to critical components of the network, damage the system, and gather confidential information, among others.
Cybercriminals send malicious emails that seem to come from legitimate resources. The user is then tricked into clicking the malicious link in the email, leading to malware installation or disclosure of sensitive information like credit card details and login credentials.
3) Spear Phishing
Spear phishing is a more sophisticated form of phishing attack in which cybercriminals target only privileged users such as system administrators and C-suite executives.
4) Man in the Middle Attack
Man in the Middle (MitM) attack occurs when cyber criminals place themselves between a two-party communication. Once the attacker interprets the communication, they may filter and steal sensitive data and return different responses to the user.
5) Denial of Service Attack
Denial of Service attacks aims to flood systems, networks, or servers with massive traffic, making the system unable to fulfill legitimate requests. Attacks can also use several infected devices to launch an attack on the target system. This is known as a Distributed Denial of Service (DDoS) attack.
6) SQL Injection
A Structured Query Language (SQL) injection attack occurs when cybercriminals attempt to access the database by uploading malicious SQL scripts. Once successful, the malicious actor can view, change, or delete data stored in the SQL database.
7) Zero-day Exploit
A zero-day attack occurs when software or hardware vulnerability is announced, and the cybercriminals exploit the vulnerability before a patch or solution is implemented.
8) Advanced Persistent Threats (APT)
An advanced persistent threat occurs when a malicious actor gains unauthorized access to a system or network and remains undetected for an extended time.
Ransomware is a type of malware attack in which the attacker locks or encrypts the victim’s data and threatens to publish or block access to data unless a ransom is paid. Learning more about ransomware threats can help companies prevent and cope with them better.
10) DNS Attack
A DNS attack is a cyberattack in which cybercriminals exploit vulnerabilities in the Domain Name System (DNS). The attackers leverage the DNS vulnerabilities to divert site visitors to malicious pages (DNS Hijacking) and remove data from compromised systems (DNS Tunneling).
