Cybercriminals employ various techniques to extract sensitive information from their victims, often exploiting vulnerabilities in personal devices.
As hacking attempts become increasingly sophisticated, experts stress the importance of adopting robust security measures to safeguard personal devices.
Cybersecurity breaches have skyrocketed, with financial losses from cyber incidents quadrupling since 2017, according to the International Monetary Fund.
While most losses hover around $0.5m, severe attacks can cost companies as much as $2.5bn once every decade.
The New York Times reports that in 2011, there were five major ransomware incidents annually. By 2024, that number has exploded to 20–25 attacks every single day. This alarming increase underscores the critical need for individuals and businesses to fortify their defences.
Below are insights from industry professionals and users who have experienced hacking firsthand, offering practical strategies to protect phones and computers.
Multi-factor authentication
According to marketing expert, Caro Smith, “Using complex, unique passwords and enabling MFA adds an extra layer of security beyond just your password.”
For instance, Facebook employs MFA to bolster account security. This feature prompts users to provide an extra layer of verification—such as entering a code sent via SMS or using an authenticator app—when logging in from an unfamiliar device.
By requiring this additional step, Facebook aims to reduce the risk of unauthorised access and better protect users’ personal information. Activating MFA is straightforward and can be done through the platform’s account settings, offering an effective defence against hacking attempts.

Keep your software updated
Smith highlights that outdated software is often exploited by hackers: “Regularly update your operating system, apps, and security software to patch vulnerabilities.”
Many breaches occur because users delay or ignore software updates, leaving their devices exposed.
Regular software updates play a critical role in shielding devices from evolving cyber threats. These updates often include security patches designed to fix vulnerabilities that hackers might exploit.
Keeping your system up-to-date is not just a recommendation—it is a vital step in protecting personal data and maintaining compliance with industry standards.
By promptly updating your devices, you reduce the risk of falling victim to cyberattacks and ensure your technology remains resilient in an ever-changing digital landscape.
Watch out for phishing attacks
Smith also warns against falling for phishing schemes: “Don’t click suspicious links or download attachments from unknown senders. Phishing emails often trick users into revealing personal information or clicking malicious links.”
Phishing is a cunning tactic used by cybercriminals to manipulate individuals into revealing confidential information, such as usernames, passwords, or financial details.
These schemes typically involve fake emails, text messages, or websites that imitate legitimate organisations, creating a false sense of trust.
The goal is to deceive victims into voluntarily sharing sensitive data, often under the guise of resolving an urgent issue or securing their accounts.
Secure your Wi-Fi connection
Using public Wi-Fi without protection can expose your data to hackers.
Smith advised, “Avoid public Wi-Fi without a VPN, especially for sensitive activities like online banking. Use a strong password for your home Wi-Fi network.”
Open or poorly secured networks present significant risks, such as data theft and identity fraud, emphasising the importance of robust security measures.
Changing default passwords, enabling encryption protocols like WPA2 or WPA3, and regularly monitoring network activity can help mitigate these threats.
Research shows that many individuals underestimate the dangers of public Wi-Fi, often accessing sensitive information without adequate protection.
This highlights the urgent need for greater awareness and proactive steps, such as using virtual private networks and avoiding unsecured networks for critical activities like online banking.
Educate yourself on hacking techniques
A cybersecurity educator, Peter Moeller, emphasises the importance of understanding modern hacking methods.
“Most hackers rely on social engineering methods, like phishing or honeypots,” Moeller said.
“With a little training, you can easily defend yourself against those.” He also recommends reviewing resources provided by banks and trusted institutions about internet security, as “educating yourself is essential.”
Leverage security tools and apps
Retired accountant, Diana Taylor, shared her approach to device protection: “I use software like Norton to detect suspicious activity and VPN protection to hide my IP location.
My devices are constantly monitored for malware and known spammers.”
