Have you ever considered all the aspects of your life bound up in that pocket-sized computer called a smartphone? It holds your conversations, schedule, photos, locations visited, purchases made, and maybe even work files.
With immense amounts of personal data, smartphones unfortunately attract hackers seeking to steal identities, money or information. In the US alone, smartphone malware infections grew by 15% and compromised 262,000 mobile banking app users just last year.
This guide will equip you to lock down your smartphone and stop 97% of hacking threats. I‘ll explain different cybercriminal techniques, plus concrete solutions to implement across your device, accounts and daily mobile usage habits. Follow these best practices and never wonder if your smartphone is secure again.
Understanding Common Smartphone Attack Tactics
Hackers employ a wide variety of schemes to infiltrate smartphones and access sensitive files within:
Malware Hidden in Apps
Bad actors develop legitimate-looking apps infected with malware prior to upload in official app stores. For example, one app posing as a currency converter infiltrated 112,000 devices – even using location access to track users for the hackers.
Phishing Scams
Through emails and texts, phishing links pretend to be from trusted brands. They may promise exclusive deals or claim your account needs reactivation. Click them and you hand over login credentials or download keylogging malware.
Public Wi-Fi Eavesdropping
Ever log into your bank account at the local coffee shop? On unsecured networks, hackers view everything you do. Many launch \"evil twin\" Wi-Fi hotspots impersonating legitimate public connections to capture transmitted data.
Bluetooth Hacking
Similar to Wi-Fi, hackers leverage Bluetooth connections to transmit spyware or gain access to call logs, messages, or photos if given permissions.
Fake Charging Stations
Public USB charging ports found in airports, hotels and shopping centers seem convenient. But hackers install them to inject malware onto devices through \"juice jacking\".
Spyware Apps
Stalkerware or monitoring software let abusive partners secretly track locations, messages and phone calls. The most sophisticated like Pegasus even record ambient audio through activated microphones.
Hackers sell compromised accounts and stolen identities on the dark web. With all your personal information at stake, it‘s critical to lock down every smartphone security gap.
10 Ways to Prevent Smartphone Hacks
While hackers employ advanced tactics, there are simple precautions to foil their plans:
1. Utilize Strong Passwords
Having weak passwords makes hacking too easy. When creating passwords:
- Minimum 8 characters
- Combine upper and lowercase letters
- Integrate numbers and symbols
- Unique for each account
- Consider a password manager to track
| Password Manager | Free Option | Unique Features |
|---|---|---|
| 1Password | No | Family password sharing |
| LastPass | Yes | Document/note storage |
| Dashlane | No | VPN included |
2. Maintain Latest Software Updates
As developers patch vulnerabilities, prompt software updates address hacking risks. Set devices to automatic updates for easiest protection.
3. Enable Two-Factor Authentication
Along with passwords, enable two-factor authentication (2FA) by text, email or verification apps for accounts containing sensitive information. Popular options supporting 2FA:
- Gmail
- Apple ID
- Social media apps
- Banking/financial apps
- Cryptocurrency exchanges
4. Research Apps Before Downloading
Only install mainstream apps from official Apple and Google app stores. Verify app ratings, reviews and developer legitimacy prior to purchasing paid apps or downloading free ones.
5. Install Antivirus Software
Antivirus software like Lookout or Norton scans devices and new app downloads for malware or hacking activity. Features like missing device locators provide additional security.
| Antivirus App | Price | Key Features |
|---|---|---|
| Lookout | Free or $3/month | Phishing and ransomware protection |
| Norton | $100-200/year | Includes VPN & dark web monitoring |
| McAfee | $80-100/year | Firewall & caller ID |
6. Connect Only on Private Wi-Fi
On shared public connections, assume your activity is visible. Never access financial accounts or share private data except on password-protected home/work networks.
7. Leverage a VPN
For encrypted traffic and anonymous browsing, virtual private networks (VPNs) are essential. NordVPN and ExpressVPN rank as top services to safeguard online activity, even on public Wi-Fi.
| VPN Service | Price | Connection Speed |
|---|---|---|
| NordVPN | $3-5/month | Fast 5400+ servers |
| ExpressVPN | $8-13/month | Lightning quick connectivity |
| ProtonVPN | $5-10/month | Free version available |
8. Turn Off Unneeded Location Services
Disable location services in settings when not actively using maps/navigation apps. Also narrow app-specific permissions – most don‘t require constant GPS access.
9. Message Over End-to-End Encryption
Normal texts and calls aren‘t encrypted. Use Signal, WhatsApp or Wire instead for secure communications across platforms.
10. Backup Data
On iOS devices, regularly backup locally to iTunes or pay for encrypted cloud storage through iCloud. For Android phones, back up to Google Drive for free. This preserves your data even if devices are lost, stolen or wiped remotely.
Remote Damage Control for Lost/Stolen Devices
Despite precautions, smartphones still get lost or stolen. Take these steps for harm reduction:
- Remotely lock device via Find My iPhone or Find My Device tools
- Wipe phone fully by remotely erasing all data
- Suspend service through wireless carrier
- Change ALL passwords stored on device
Backups restore personal files like contacts and photos. But financial and identity theft risks call for more urgent actions if a thief has your phone.
Expanded Mobile Security Beyond Phones
Smartwatches and tablets also require protection given their connectivity features. Here are key risks and how to combat them:
Smartwatches Risks
- SyncingFitness data to unsecured public Wi-Fior PCs
- Intercepted payment info if connected to wallet/bank apps
- Tracking children‘s locations if connected through family plans
Securing Smartwatches
- Encrypt fitness data
- Careful pairing only with personal devices
- Enable offline use modes with no Wi-Fi/Bluetooth
Tablet Risks
- Greater gaming and web browsing risks if accessing unsafe sites
- Higher child safety threats with more involved app ecosystem
Securing Tablets
- Strong parental controls over app downloads/usage
- Install antivirus and VPN apps for full protection
- Monitor all installed apps for appropriate age ratings
Maintaining Vigilance Over Time
Don‘t let great security one day lead to complacency down the road. Regularly follow these best practices:
- Update all device operating systems and individual apps promptly
- Reassess app permissions and remove anything unnecessary
- Check VPN/antivirus app subscriptions are current
- Backup data to the cloud on a weekly basis
- Delete unused apps and files taking up excessive storage space
- Only connect to personal Wi-Fi networks for sensitive logins
