In this video, I explain malware threats. Malware, short for malicious software, refers to any software designed to harm or exploit any computing device, server, client, or computer network.

Over the years, various types of malware threats have emerged, each with unique functionalities and purposes. Below are some of the most common types:

Viruses: These are malicious software programs that, when executed, replicate by infecting other programs and files on the computer. They often require human intervention (like opening a file or running a program) to spread.

Worms: Unlike viruses, worms can spread without human intervention. They exploit vulnerabilities in software to infect systems and often spread across networks.

Trojans: Named after the Trojan horse from ancient mythology, these malware types disguise themselves as legitimate software. Once installed, they can deliver their malicious payload, which might involve providing backdoor access to an attacker or stealing information.

Ransomware: This type of malware encrypts the victim's files and then demands a ransom payment to decrypt them. Examples include WannaCry and NotPetya.

Spyware: As the name suggests, spyware is designed to spy on the user's activities. It can capture keystrokes, screenshots, browser histories, and more, sending this data back to the attacker.

Adware: While not always malicious in intent, adware displays unwanted advertisements to the user, often leading to a degraded browsing experience. Some adware can be intrusive and can also come bundled with spyware.

Rootkits: These are designed to provide stealth access to a computer's system. Once installed, they grant cybercriminals a high level of control over the infected device, often without detection.

Bots and Botnets: Infected computers can be turned into "bots" that, when networked together, form a "botnet". Cybercriminals use these botnets for various malicious activities, such as launching distributed denial-of-service (DDoS) attacks.

Fileless Malware: Rather than relying on files stored on the system, fileless malware exploits in-memory processes to carry out its activities, making it harder to detect by traditional antivirus solutions.

Mobile Malware: Specifically designed for mobile devices, these can steal data, send premium-rate SMS messages without the user's knowledge, or perform other malicious tasks.

Cryptocurrency Miners: Malware designed to utilize the infected system's resources to mine cryptocurrencies.

Logic Bombs: These are pieces of code that are set to execute under certain conditions. For instance, a logic bomb could be set to delete critical system files on a particular date.

Keyloggers: Capture and record user keystrokes to gather sensitive information, such as passwords or credit card details.
