Hack-proof: Cybersecurity tips you can't afford to ignore

Back in the '90s, the expansion of the World Wide Web (yep, that’s what we called the Internet back then) ushered in an era of incredible opportunities and opened the door to new industries. The new technological advances, however, came at a price, as they brought with them new challenges. Email accounts were plagued by the constant bombardment of spam, and viruses wreaked havoc on computer networks. Hackers expanded the scope of crime to include stealing people’s personal data online and duping them into giving out confidential information. This put people’s privacy, finances, and even their identities at risk.

Unfortunately, since the '90s, the situation hasn't improved; in fact, hacking threats have grown more sophisticated and elusive. It seems that the more we embrace technology, the wider we inadvertently open the door for cybercriminals, creating an endless tug-of-war.

But let’s shake off all that negativity because there’s a way to win this never-ending battle, and we’re going to show you how! In this article, we’ll share the top 10 ways you can protect yourself and your computer from hackers. Spoiler alert, being proactive and using cybersecurity tools like Guardio are probably the best ways to make sure you’re safe online. But we’re getting ahead of ourselves. Put on your swimming goggles, and let’s dive in!

Are hacked computers really that serious?

At first glance, computer hacks might seem like a mere inconvenience or something that happens to others. You might be wondering, “What if my computer gets hacked, so what? My vacation pics and Spotify playlist get stolen – who cares?” But in reality, this seemingly trivial scenario underscores a much larger issue. While losing personal files and entertainment might not seem catastrophic, it's just the tip of the iceberg.

When your computer is compromised, it opens the door to a host of more significant dangers. Hackers can exploit stolen information for financial gain, potentially leading to drained bank accounts, stolen credit card numbers, hijacked social media accounts, and even identity theft. They can also exploit your compromised device as a launching pad for more extensive cyberattacks, affecting not only your life but potentially your friends and families.

“It's never gonna happen to me” - Famous last words…

Whether you're a tech guru or not, the reality remains the same: cybercriminals are equal-opportunity assailants, targeting both the digitally seasoned and the technologically uninitiated. Mat Honan, a senior writer for WIRED, had to learn that the hard way. In the span of a single hour, Mat's digital life unraveled, shedding light on the vulnerability that lies beneath our interconnected world.

The attack began when hackers compromised his Google account, wiping out all of his personal data and digital memories. But the story doesn't stop there. The hackers proceeded to seize control of his Twitter account, unleashing a barrage of hateful, racist, and homophobic messages. Not only was this intrusion into his online persona invasive, but it was also deeply distressing.

Yet, the most catastrophic blow was yet to come. Mat's AppleID account was breached, unleashing a nightmare scenario. The hackers remotely wiped all data from his iPhone, iPad, and MacBook—effectively erasing his digital existence.

In the aftermath of this digital nightmare, Mat's ordeal wasn't confined solely to the loss of data and the hijacking of his online presence. The consequences rippled through every facet of his life. His online identity had been stolen, his integrity undermined, and his financial information exposed to malicious actors. The damage reached beyond the digital realm, tarnishing his reputation and sowing the seeds of distrust.

How to protect your computer from hackers and viruses

Knowing how to protect yourself from hackers is crucial - Here are the top 10 ways to protect your computer from hackers, plus some practical tips:

  1. Regular software updates: Ensuring all your software, including your operating system (OS), is up-to-date is critical. Developers release updates to fix security vulnerabilities that hackers try to exploit. Setting your system up for “automatic updates”, will guarantee that your defenses are up to date in case of any emerging threats.

  2. Use firewalls: Firewalls serve as your computer's first line of defense against unauthorized access from the internet. They monitor incoming and outgoing network traffic, blocking or allowing data based on a set of security rules. A well-configured firewall can prevent hackers from infiltrating your system. Whether you use Windows, Chrome OS, or have a Mac, built-in firewalls are usually preinstalled in your system. Make sure they’re on in your System Preferences.

  3. Secure your Wi-Fi network: Open Wi-Fi networks are vulnerable to intrusion. To protect your home network, enable WPA3 encryption and choose a strong, unique passphrase. Also, change your router's default login credentials and regularly update its firmware for security patches. Learn more.

  4. Invest in quality anti-malware & antivirus software: Simply put, getting top-notch online security software is like putting a digital fortress around your precious data. Antivirus programs, as their name suggests, tackle classic threats like viruses. But let's face it, the bad guys have evolved. That's where online security software swoops in to detect and boot out a whole bunch of nasty stuff, from phishing attacks to spyware and Trojans. That’s where Guardio comes in - Guardio is a browser extension and app that blocks cyber attacks and hackers from gaining access to your computer in the first place.

  1. Avoid suspicious links and emails: Phishing attacks are a common way hackers compromise systems. Be cautious of unsolicited emails or messages containing suspicious links or attachments. Verify the sender's identity and don’t click on links or download email attachments if you’re not sure where exactly they’re coming from.

  2. Password best practices: Create strong passwords for each online account. Utilize a mix of uppercase and lowercase letters, numbers, special characters, and make sure they are unique. Consider using a password manager to securely store and autofill your passwords. Change passwords periodically, especially after data breaches.

  3. Regular backups: Regularly back up your important data to cloud services or external drives. This practice ensures you can recover your data in case of a ransomware attack, hardware failure, or data loss. Automated backups are especially convenient and reliable.

  4. Enable Multi-Factor Authentication (MFA): MFA adds an extra layer of security by requiring users to provide two or more forms of verification to access an account. This typically includes something they know (password) and something they have (a temporary code sent to their smartphone). Enabling MFA significantly enhances account security.

  5. Be cautious with downloads: Only download files or software from reliable and official sources. Avoid downloading content from unofficial or suspicious websites, as they may contain malware or other security risks. Always verify the authenticity of the source before downloading anything.

  6. Educate yourself on the latest scams: Stay informed about the latest online scams and cyber threats. Knowledge and awareness are powerful defenses. Regularly read about cybersecurity news, attend webinars or workshops, and educate yourself about common tactics used by hackers.
