A lot of people don’t think it’s important until it’s too late, but I’m going to show you that it’s something everyone should be aware of. I’m going to break down everything from different types of cybercrimes to tips and tricks to protect yourself so that by the end of this video, you’ll feel confident enough to protect yourself online.
Common Types of Cyberattacks
Phishing is a type of online fraud involving emails or other messages to trick people into sharing personal information or clicking on links that lead to malware. The goal is to get victims to respond quickly without thinking, resulting in them giving away sensitive information or downloading malicious software.
One common technique is called “spoofing,” where the hacker creates an email that looks like it’s from a legitimate authority, like your bank or a government agency. The email will usually enclose a link that takes you to a fake website, where you’re asked to enter your login details or other personal information.
Malware is a broad term for any type of malicious software that can cause harm to your computer. This can include viruses, Trojan horses, spyware, and adware. Some malware is designed to steal information, like passwords or credit card numbers. Other malware is designed to damage your computer or disrupt its normal operation.
Without your awareness, malware can be installed on your computer, often through email attachments or downloads from unofficial websites. Once installed, it can be tough to remove without the help of an antivirus program. To protect your computer from malware, it is important to only download files from trusted sources and to run a reliable antivirus program.
A denial-of-service attack (DoS attack) is a type of cyberattack in which the attacker seeks to disable a network by flooding it with requests, rendering it inaccessible to its users. DoS attacks are often launched by botnets, networks of infected computers that can be controlled remotely by the attacker.
These botnets can generate a large volume of traffic, making it difficult for legitimate users to access the targeted system. In some cases, a DoS attack can cause entire websites or online services to go offline. DoS attacks are often used as a tool for political or ideological warfare, and they can have a major consequence on businesses and individuals alike.
A SQL injection is a type of security exploit in which malicious code is inserted into a database in order to execute unauthorized queries. SQL injections can be used to gain access to sensitive data, such as passwords or credit card numbers. They can also be used to modify or delete data.
SQL injections are a serious security threat and can be very difficult to detect and prevent. Sometimes, they can only be detected by manually reviewing the injected code.
Ransomware is a type of malware that encrypts a victim’s files, making them inaccessible, and then demands a ransom be paid for the victim to regain access to their files. And Ransomware is typically spread through phishing emails or malicious websites. Once a victim’s system is infected with ransomware, the malware will begin to encrypt their files.
In some cases, ransomware will also delete any backups the victim has of their files. The ransom demanded can range from a few hundred dollars to several thousand, and it is often payable in Bitcoin. There have been reports of victims that paid the ransom but were not able to access their files.
Tips to Help You Stay Safe Online
According to Cybersecurity Ventures, more than half of all cyberattacks are aimed at small businesses. And within six months, 60% of them went out of business due to the damage caused by the attack.
That’s why it’s so necessary for individuals and businesses of all sizes to take cybersecurity seriously and to put in place defense to protect themselves. Here are some tips to help you stay safe online:
Don’t open emails from unknown senders
Many people have been deceived into clicking on fake links or attachments that can install malware onto their computer or device. Sometimes these emails look like they’re from a legitimate sender, but they’re not. They may even look like they’re from someone you know. That’s why it’s important to be cautious about any email you receive from an unknown sender.
If you’re not certain whether an email is safe, don’t open it. And if you do accidentally open a suspicious email, don’t click on any links or attachments. Delete the email right away and run a virus scan on your computer or device to be safe.
Install a firewall and antivirus software
When it comes to shielding your computer from malware, two of the most important tools at your disposal are a firewall and antivirus software. A firewall helps to block incoming connections from unknown or untrusted sources, while antivirus software scans your system for malicious code and removes any threats that are found.
Both of these tools are essential for keeping your computer safe, but they work best when used together. Antivirus software can miss some threats, and a firewall will not stop every attack, but when used in combination, they provide a much higher level of protection.
Use strong passwords
One of the simplest and most effective ways to protect your accounts is to use strong passwords. A strong passcode should be at least eight characters long and contain a mix of numbers, upper and lowercase letters, and symbols.
It’s also best to use unique passwords for each of your accounts. That way, if one of your passwords is compromised, the rest of your accounts will still be safe.
Enable Multiple Factor Authenticator
Multiple factor authentication (MFA) is an important security measure that can help protect your online accounts from unauthorized access. MFA implies you use two or more different factors to verify your identity before being able to log in. The most common type of MFA is using a password and a code that is sent to your mobile device via text or email.
This means that even if someone else knows your password, they would also need access to your phone to log in. MFA can also be used with biometrics, such as fingerprint or iris scanners. Setting up MFA may require a few extra steps during the login process, but it can ultimately help keep your account safe and secure.
Avoid Unnecessary Downloads
Downloading files from the internet can be risky, as these files may contain malware. So it’s important to only download files from websites that we trust and to be careful about what we click on.
When we download files, we essentially open our computers up to potentially harmful content. Any file that we download has the potential to be infected with malware, which can wreak all sorts of havoc on our systems.
Use a VPN
Virtual Private Network is a gizmo that can help to keep your online activity private and secure. VPNs work by encrypting the data that you send and receive online, making it unreadable to anyone who might be trying to interlope on your traffic.
This means that even if someone were to intercept your data, they would not be able to read it. VPNs are an important tool for anyone who wants to keep their online activity private, whether they’re using public Wi-Fi or just want to avoid being tracked by their ISP.
Check your microphone and webcam
If you have a webcam and microphone, it’s important to make sure that these devices are secure. Hackers can gain access to your microphone and webcam to spy on you, so it’s important to take steps to protect yourself.
One way to do this is to cover your webcam with a piece of tape when you’re not using it. This will hold back anyone from being able to activate your webcam without your knowledge. Test and check your webcam to make sure that it is not being used without your permission. You should also be careful about what applications have access to your microphone and webcam.
Invest in Cybersecurity Products
Many different cybersecurity products on the market can help protect your devices and data from malware. These products come in different forms, including antivirus software, firewalls, and VPNs.
Investing in one or more of these products is a good way to help keep your computer safe from malware. Be sure to do your research to find the product that best fits your needs.
Stay up-to-date on security threats
The cybersecurity landscape is constantly transforming, and new threats are emerging all the time. It’s important to stay up-to-date on the latest security threats so that you can be aware of the dangers and start to protect yourself.
Be aware of what you share online
Personal information like our addresses, phone numbers, and birthdates can all be used by criminals to steal our identities or break into our accounts. So it’s important to only share this information with websites that we trust and to make sure that our privacy settings are set to the most secure level.
