Understanding Various Online Security Risks

The internet can be a risky environment with numerous security threats that can cause harm in many ways. Recognizing these dangers is crucial to safeguard your digital life. Below are some common online security threats to be aware of:

Malicious Software
Malicious software, or malware, encompasses a range of intrusive or harmful programs like viruses, worms, spyware, Trojans, and rootkits that can damage or compromise your device.

Deceptive Security Alerts
Fake security pop-ups often appear to warn users of threats. These alerts encourage clicking links to install malware or remove non-existent issues, posing significant risks. Microsoft provides guidance to identify and avoid such scams.

Malicious Applications (Trojan Horse)
Harmful programs disguising as genuine apps can infiltrate your system, granting cybercriminals access to control your device, spy on activities, or steal sensitive data.

Botnets
Networks of compromised devices controlled remotely by hackers, known as botnets or zombie computers, can be used to send spam, launch denial-of-service attacks, or conduct other malicious activities.

Phishing Attacks
Cybercriminals send fake emails pretending to be trustworthy entities like banks or service providers, aiming to trick users into revealing personal or financial information.

Social Engineering Techniques
Tactics such as pretexting, tailgating, or quid-pro-quo trick individuals into divulging confidential details through deception or impersonation.

Backdoors
Unauthorised programs or codes that bypass security measures, allowing hackers to access systems without permission.

Rootkits
Tools that grant attackers administrative access to devices or networks, often installed via vulnerabilities, and may include spyware to monitor activity.

Hijacking
When cybercriminals take control of a system, browser, or webpage, redirecting users to malicious sites or stealing control for malicious purposes. Types include network, browser, and website hijacking.

Brute Force Attacks
Attackers use software to systematically guess passwords or decrypt encrypted data by trying numerous combinations, often securing access to victims' accounts.

The best defense against these threats is installing reputable antivirus or internet security software to protect your devices and data effectively.
