Cybersecurity is the practice of defending computers, servers, mobile devices, electronic systems, networks, and data from malicious attacks. It’s also known as information technology security or electronic information security.
The term “cybersecurity” applies in a variety of contexts, from business to mobile computing, and can be divided into a few common categories
In light of the increasing prevalence of cybercrimes, there is a growing need to address this critical issue. It’s a common misconception that cyberattacks happen instantly, with people often saying, “With just one click, my money is gone,” or “My phone is hacked.“ However, the reality is that no device can be hacked without some form of user consent, whether knowingly or unknowingly given. These breaches often occur when individuals unknowingly grant access to their data through various means, such as social media, downloading files from the internet, or installing malicious applications. It is essential to raise awareness about these potential threats to better protect ourselves in the digital age.
We all recognize that privacy is of paramount importance, especially in today’s digital age. Protecting our devices from cyber threats is essential. You may wonder, what types of cyber threats are we likely to encounter? Here’s what you need to know.
Types of cyber threats
In this case, we won’t dive too deep into technical details. If you’re looking for in-depth knowledge, there are plenty of articles available online. However, this article aims to explain cybercrime in a simple and accessible way for easy understanding.
1.Cybercrime
Any crime that involves the use of laptops, mobile phones, or other electronic devices is classified as cybercrime. Examples include drug trafficking via the dark web, human trafficking, and the operation of illegal websites that distribute pirated movies or software. All of these activities fall under the umbrella of cybercrime.
2. Cyber-attack
A cyberattack refers to an incident where a hacker, driven by a specific motive, seeks to steal information from other systems or disrupt their functionality. This can involve shutting down a website, server, or any device entirely. Essentially, a cyberattack is an attempt to compromise or damage a system.
I believe we’ve clarified the difference between cybercrime and cyberattacks. Do you know how hackers gain access to a victim’s system? They often do this through the use of malware or Remote Access Trojans (RATs).
There are a number of different types of malware, including:
There are numerous methods that hackers use to target and attack victim systems. Here is a simplified overview.:
- Virus: A harmful program that copies itself and attaches to clean files, spreading through your computer and causing damage to other files.
- Trojans: A type of malicious software that pretends to be legitimate. Hackers trick you into installing it, and once it’s on your computer, it can cause harm or steal your data.
- Spyware: A sneaky program that secretly monitors what you do on your computer, such as recording your credit card information, so that hackers can use it.
- Ransomware: A dangerous program that locks your files and data, threatening to delete them unless you pay a ransom.
- Adware: Software designed to show you unwanted ads, which can sometimes be used to spread harmful software.
- Botnets: Groups of infected computers controlled by hackers to carry out tasks online without the owners knowing.
Effective Strategies for Protecting Your System from Cyber Threats
Protecting our systems is quite challenging in today’s digital world. If you’re an individual, the approach to keeping your system safe is different from what a company or organization would use, which requires a separate strategy.
This information is intended solely for individuals and may not be suitable for large companies or organizations. For more comprehensive guidance, consulting cybersecurity experts is recommended. Please note that we are providing only basic information here.
Cyber safety tips – protect yourself against cyberattacks
Use strong passwords:
This is one of the most effective ways to protect your system. Opt for passwords that include a mix of symbols, numbers, and lowercase letters. Consider using a password generator to create robust and secure passwords.
Avoid installing third-party apps:
Only download applications from reputable sources such as official app stores or trusted software providers. Refrain from downloading apps from unverified websites or social media platforms like Instagram and WhatsApp. In particular, some WhatsApp groups, often referred to as “WhatsApp universities” in India, distribute malicious software disguised as attractive offers or contests. These apps, often APK files, are designed to target Android users and may secretly collect and share your personal information over the internet without your consent.
Enable two-factor authentication (2FA):
This enhances your security by adding an additional layer of protection. It significantly reduces the risk of unauthorized access to your accounts.
Avoid Suspicious Links:
Do not click on unknown or untrusted links, particularly from websites offering pirated movies or apps. Such sites often inadvertently download viruses onto your device. Always exercise caution and avoid clicking on links if you are unsure of their legitimacy. If you are aware of what you are doing, consider other approaches to ensure your online safety.
These are fundamental methods to protect your system and other devices. While installing antivirus software, monitoring your network traffic, and using a VPN on public Wi-Fi are advanced measures, they provide additional layers of security. Note that a VPN should be purchased from a reputable provider, as free versions often lack adequate privacy protection and may expose your device to security risks.
What If Hacked?
If your device has already been compromised, the best course of action is to reset it and restore your data from a backup. Ensure you back up any important information before performing the reset to prevent data loss. If your social media accounts, such as Instagram, Facebook, Twitter, or LinkedIn, have been hacked, contact the support services for those platforms. Provide the required evidence to verify your identity and regain access to your accounts. This approach is typically the most effective solution following a security breach.
