Cyber threats

Introduction to Cyber Threat

Cyber threats refer to malicious attempts to damage, disrupt, or gain unauthorized access to computer systems, networks, or digital data. These threats can come from various sources, including individual hackers, organized crime groups, nation-state actors, or even insiders with malicious intent. Cyber threats evolve constantly, becoming more sophisticated and dangerous over time.

The potential dangers or attacks that target computer systems, networks, or digital data with the intent to cause harm, steal information, disrupt services, or gain unauthorized access. These threats can come from various sources, including hackers, cybercriminals, and even malicious software.

Some common types of Cyber Threats

• Malware: Malicious software such as viruses, worms, trojans, and ransomware that can damage, disrupt, or gain unauthorized access to systems.
• Phishing: Fraudulent attempts to obtain sensitive information, such as usernames, passwords, and credit card numbers, by impersonating a trustworthy entity in emails, websites, or messages.
• Ransomware: A type of malware that encrypts files on a victim’s system, holding them hostage until a ransom is paid to the attacker.
• Denial-of-Service (DoS) Attacks: Overloading a network or server with excessive traffic, causing it to crash or become inaccessible.
• Man-in-the-Middle (MitM) Attacks: Where an attacker intercepts and potentially alters communications between two parties without their knowledge.
• SQL Injection: A technique where an attacker inserts malicious SQL code into a vulnerable database query, potentially gaining access to sensitive information.
• Insider Threats: Attacks or data breaches caused by people within an organization, such as employees or contractors, who misuse their access to information.
• Zero-Day Exploits: Attacks that target vulnerabilities in software or hardware that the vendor has not yet discovered or patched.
• Social Engineering: Manipulating people into divulging confidential information or performing actions that compromise security.
• Advanced Persistent Threats (APTs): Sophisticated, long-term cyberattacks aimed at stealing sensitive data or compromising critical infrastructure
