Key Takeaways
- iPhones and Android devices can both be compromised — no platform is completely immune to threats.
- Antivirus software alone does not protect against phishing, weak passwords, or unpatched software.
- A device that feels fast and normal can still be silently compromised.
- Public charging stations and app stores carry real, underestimated security risks.
- Security updates exist for a reason — delaying them leaves known vulnerabilities open.
Why Device Security Myths Are Dangerous
Security myths are particularly harmful because they feel reassuring. When people believe their device is protected by default — because of the brand they chose or the software they installed — they skip the basic habits that actually keep them safe. The result is a gap between perceived protection and real exposure.
These misconceptions span every type of device and every level of technical experience. They're worth examining directly, because the corrections are straightforward and the actions they lead to are genuinely effective. For related misconceptions that affect how people connect, see our piece on public Wi-Fi safety myths and network security myths that carry similar risks.
Myth
iPhones don't get malware, so I don't need to worry about security on mine.
Fact
iPhones face real threats including phishing attacks, malicious profiles, and vulnerabilities in apps and the OS itself.
Apple's closed ecosystem does reduce certain risks, but it creates a false ceiling of confidence. Researchers have documented sophisticated attacks — including zero-click exploits — that require no user interaction at all. Beyond malware in the traditional sense, iPhone users are still fully exposed to phishing links in messages, fraudulent apps, and credential theft. Security vigilance applies regardless of which platform you use.
Myth
I have antivirus installed, so my device is fully protected.
Fact
Antivirus is one layer of defence, not a complete security solution.
Antivirus software is useful for catching known malicious files, but it cannot protect you from phishing emails that trick you into handing over your credentials, weak passwords that are guessed or leaked in data breaches, or unpatched software vulnerabilities. A layered approach — combining strong passwords, two-factor authentication, regular updates, and careful clicking habits — provides far better coverage than any single tool.
Myth
If my device is running fine, it hasn't been hacked.
Fact
Many forms of compromise are designed to be invisible so they can operate undetected for as long as possible.
Modern malware and spyware are engineered to avoid disrupting normal device performance. Attackers benefit most when you don't know you've been compromised — giving them extended access to your accounts, messages, or camera. Indicators of compromise are often subtle or absent entirely. Relying on your device 'feeling normal' is not a reliable security check.
Myth
Charging my phone at a public USB port is perfectly safe.
Fact
Public USB charging ports can be used to transfer data or install malicious software — a technique known as 'juice jacking.'
USB connections were designed to transfer both power and data simultaneously. Compromised public charging stations — found in airports, hotels, and cafes — can exploit this to access your device or push unwanted software. Using your own AC adapter plugged into a wall outlet, or a USB data blocker (a small passthrough device that allows power but blocks data pins), eliminates this risk entirely.
Myth
Apps from official stores like the App Store or Google Play are always safe.
Fact
Both major app stores have hosted malicious or deceptive apps that passed initial review processes.
Official app marketplaces have security screening, but it is not foolproof. Researchers regularly identify apps that harvest excessive data, display fraudulent subscription prompts, or contain hidden adware. Checking app permissions carefully, reading recent user reviews, and verifying the developer's identity before installing anything are habits that matter — even on official platforms.
What Genuine Device Security Actually Looks Like
Effective device security is built from several overlapping habits rather than a single solution. Keeping your operating system and apps updated closes vulnerabilities that attackers actively scan for — updates are not optional maintenance, they are your primary defence against known exploits.

Users who skip available software updates
Surveys consistently find a large share of users delay or ignore OS and app updates, leaving known security patches unapplied.

Breaches involving weak or stolen credentials
According to Verizon's Data Breach Investigations Report, the majority of hacking-related breaches involve compromised passwords.
Strong, unique passwords for each account — combined with two-factor authentication — dramatically reduce the impact of a data breach on any one service. If you're uncertain whether your password habits are working against you, our guide on password myths covers the most common errors in plain terms.
Being cautious about what you install, where you charge your device, and which links you click completes the picture. Scam attempts increasingly arrive through apps and messages rather than email alone — recognising the warning signs of a scam is a skill worth building. For practical day-to-day guidance, the Smartphone Tips & Tricks hub and Network Security hub offer actionable starting points.
Don't Rely on Any Single Security Tool
No app, setting, or device feature provides complete protection on its own. Treating antivirus software, a VPN, or a specific platform as a full solution leads to overlooking the habits — like updating software and verifying links — that matter most. Security works best as a set of layered practices, not a single switch to flip.
