How do phones pick up viruses?

Much like computers, mobile phones are vulnerable to various digital threats. In today’s interconnected age, these little gadgets are more than just communication tools; they’ve become our lifelines, holding crucial personal and financial data. But how exactly do these viruses infiltrate our mobile lifelines?

How Do Viruses Get on Your Phone?

One of the most common questions asked by mobile phone users is, ‘How do these viruses find their way onto my device?’. There are several gateways, some obvious and others not so apparent:

• Suspicious apps: Downloading apps from unofficial or third-party app stores can introduce harmful software onto your phone. Not all, but some of these apps contain malicious code.
• Phishing emails and messages: Cybercriminals often send deceitful messages with infected attachments or links. Once clicked, they can install malicious software onto your phone.
• Compromised Wi-Fi networks: Using public Wi-Fi networks might seem convenient, but they often lack proper security protocols, making it easy for hackers to access your device.
• Software vulnerabilities: Outdated software can have vulnerabilities that malicious actors exploit to introduce malware.

Security Settings on My Phone

The frontline defence against digital threats is the phone in your hand. There’s a range of security settings that, when activated, can protect your phone. Let’s explore some of them:

• Regular software updates: Always ensure that your phone’s operating system and apps are updated. Software developers frequently release updates to fix security vulnerabilities.
• Enable lock screen: A simple but effective measure. By requiring a PIN, pattern, or fingerprint to unlock your phone, you deter unauthorised access.
• Two-factor authentication: A feature available on many apps and services. It requires a second form of identification (often a text or email code) in addition to your password.
• Review app permissions: Be vigilant about which apps can access your data. Regularly review and adjust permissions in the settings.

Phone Security Settings

Take a deeper look into your phone’s armoury, and you will find additional settings aimed at safeguarding your digital world. These include:

• Remote lock and wipe: Features like ‘Find My iPhone’ or Android’s ‘Find My Device’ allow you to remotely lock or erase your phone if lost or stolen.
• VPN services: These tools encrypt your data, making it difficult for hackers to intercept when you are online, especially on public Wi-Fi.
• Web protection: Some phones offer built-in settings or recommend apps that alert you when visiting potentially harmful websites.

My Phone Security Settings

The responsibility of maintaining a virus-free phone doesn’t rest solely on the manufacturer; you also have an integral part to play as the user. Customise your settings to fit your usage:

• Regular backups: Ensure you back up your data regularly. If something goes wrong, you won’t lose your important files.
• Limited ad tracking: By limiting ad tracking in your settings, you reduce the risk of adware, which often serves as a gateway to more sinister threats.
• Review browsing habits: Being cautious about the sites you visit and links you click on goes a long way in keeping viruses at bay.
• Use trusted security apps: There are plenty of legitimate security apps that can scan for and remove threats. However, always ensure you download them from official app stores.

What is Mobile Malware?

We’ve briefly covered how viruses find their way onto your devices, but what are they exactly? In most cases, it’s malware. Malware – a term derived from ‘malicious software’ – encompasses various harmful software types, from spyware to ransomware. Each has its modus operandi, making understanding them crucial.

Mobile Spyware

Spyware is a silent observer. Once installed on your device, it monitors your activities, logging keystrokes or tracking browsing habits. The information is then sent to cybercriminals who can exploit it for identity theft or fraud.

Prevention Tips:

• Avoid clicking on suspicious links.
• Only download apps from trusted sources.
• Periodically check your phone for unfamiliar apps.

Mobile Ransomware

Unlike spyware, ransomware is far from silent. It encrypts your files, making them inaccessible. You’re then greeted with a demand: pay a fee to regain access. While it’s more common on PCs, mobile ransomware is an emerging threat.

Prevention Tips:

• Regularly back up your data.
• Do not pay the ransom; it doesn’t guarantee the return of your data.
• Seek professional help if infected.

Adware

Adware might seem benign, focusing on bombarding users with ads. However, it’s more sinister than it appears. By pushing fraudulent ads, it can redirect users to malware-laden sites.

Prevention Tips:

• Use ad blockers or browsers with built-in ad-blocking features.
• Regularly clear browser cookies.
• Stay wary of too-good-to-be-true offers.

Cultivating Safe Habits with Digital Hygiene

Digital hygiene goes beyond just your phone’s settings. Cultivating good digital habits is paramount in ensuring a safer online experience.

Safe Browsing:

Browsing the web can be like navigating a minefield – it’s not always clear where the dangers are lurking. To keep yourself safe:

• Always check for ‘https://’ in website URLS, the ‘s’ indicates a secure site.
• Stay clear of pop-up windows that urge immediate action.
• Trust your instincts. If a site feels off, leave it.

Password Management:

Passwords are more than just access codes; they’re the first line of defence against unauthorised access.

• Create complex passwords with a combination of letters, numbers, and symbols.
• Avoid using the same password across multiple sites.
• Consider using a trusted password manager.

Social Engineering

Viruses and malware aren’t always about exploiting software vulnerabilities. Often, they target human psychology.

Phishing Attacks

Phishing is a method used by cybercriminals who pose as trustworthy entities, sending messages or emails that lure users into providing sensitive data. To protect yourself from these attacks:

• Never share personal information via email or SMS.
• Check email senders. Often, phishing emails come from misspelled versions of official domains.
• Stay wary of unsolicited communications, especially those prompting urgent action.

Baiting

Who doesn’t love a freebie? Cybercriminals know this all too well. Baiting involves offering something enticing to distribute malware. To protect yourself, consider the following:

• Remember: If it’s too good to be true, it probably is.
• Only download software from trusted sources.
• Regularly update and scan your device with security software.

The Role of App Stores

App stores are the primary avenues through which we discover and install new software on our phones. As gateways, they play a vital role in our digital ecosystem.

Major app stores, like Apple’s App Store or Google’s Play Store, undertake a review process before allowing an app to be listed. This review, in theory, filters out malicious or poorly coded software, ensuring that users get quality apps that adhere to specific guidelines.

However, this system isn’t completely without risks. Occasionally, rogue apps might slip through the cracks. Sometimes, these apps might carry with them malicious intent.

Tips for Safe App Downloads

• Read reviews and check ratings before you download. Often, the collective experience of the user base is a good indicator of an app’s legitimacy.
• Be cautious of apps that ask for excessive permissions. A wallpaper app, for example, shouldn’t need access to your contacts.
• While third-party app stores might offer tempting exclusives, it’s best to stick to official channels wherever possible.

As we integrate more technology into our lives, the threats we face evolve. From the software we install to the links we click, every action holds potential risks. But with a mix of knowledge, caution, and the right tools, we can navigate the digital realm with confidence.
