CYBERSECURITY: THREATS AND IT’S SOURCES
What is a Cyber security Threat?
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.
1.Malware:
Malware attacks are the most common type of cyberattack.Malware is defined as 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 system, malware can block access to critical components of the network, damage the system, and gather confidential information, among others.
2.Phishing:
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 a 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 at flooding systems, networks, or servers with massive traffic, thereby 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.Ransomware:
Ransomware is a type of malware attack in which the attacker locks or encrypts the victim's data and threatens to publish or blocks access to data unless a ransom is paid.
9.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.
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 exfiltrate data from compromised systems (DNS Tunneling).
SOURCES OF THESE CYBER SECURITY THREATS
1.Nation States:
Cyber attacks by a nation can inflict detrimental impact by disrupting communications, military activities and everyday life.
2.Criminal Groups:
Criminal groups aim to infiltrate systems or networks for financial gain. These groups use phishing, spam, spyware, and malware to conduct identity theft, online fraud, and system extortion.
3.Hackers:
Hackers explore various cyber techniques to breach defenses and exploit vulnerabilities in a computer system or network. They are motivated by personal gain, revenge, stalking, financial gain, and political activism. Hackers develop new types of threats for the thrill of challenge or bragging rights in the hacker community.
4.Terrorist Groups:
Terrorists conduct cyber attacks to destroy, infiltrate, or exploit critical infrastructure to threaten national security, compromise military equipment, disrupt the economy, and cause mass casualties.
5.Hacktivists:
Hacktivists carry out cyberattacks in support of political causes rather than financial gain. They target industries, organizations, or individuals who don't align with their political ideas and agenda.
6.Malicious Insiders:
Insiders can include employees, third-party vendors, contractors, or other business associates who have legitimate access to enterprise assets but misuse those accesses to steal or destroy information for financial or personal gain.
7.Corporate Spies:
Corporate spies conduct industrial or business espionage to either make a profit or disrupt a competitor‘s business by attacking critical infrastructure, stealing trade secrets, and gaining access.
In conclusion to prevent these threats, organizations must refine their cybersecurity program. An effective cybersecurity program can help organizations disrupt attacks as they occur, reduce recovery time, and contain future threats.
