These days, it’s so important to know who’s calling your mobile with the number of scams that seem to be targeting us. Unfortunately, scammers are getting quite clever in obtaining personal information when impersonating government agencies like Centrelink and the ATO, along with Telcos like Telstra.
From suspicious SMS messages to deceptive app downloads, mobile scams are becoming increasingly sophisticated. As smartphones become our digital wallets, ID vaults, and work hubs, they also become lucrative targets for cybercriminals.
This article explores the most common types of mobile scams, how they work, and—most importantly—how you can protect yourself against them.
Common Types of Mobile Scams
1. Phishing SMS (Smishing)
Scammers send fake messages impersonating banks, delivery services, or government agencies to trick you into clicking malicious links.
Example: “Your parcel is held due to unpaid customs fees. Pay now: [fake link]”
2. Vishing (Voice Phishing)
Fraudsters call pretending to be from tech support, your bank, or law enforcement, urging you to take urgent action like transferring money or providing sensitive info.
3. Malicious Apps
Fake apps disguised as games, utilities, or updates often request unnecessary permissions and install malware or spyware.
4. QR Code Scams
QR codes placed in public or sent via text redirect you to phishing sites or prompt you to download malicious software.
5. SIM Swap Attacks
Hackers transfer your phone number to a new SIM card, allowing them to intercept texts and calls—including your 2FA codes.
Red Flags to Watch For
- Unsolicited messages or calls urging immediate action
- Generic greetings like “Dear customer”
- Poor grammar or spelling
- Links that don’t match the official domain
- Apps requesting access to contacts, messages, or location unnecessarily
How to Protect Yourself
1. Don’t Click Suspicious Links
Never tap on links in unsolicited messages. If unsure, contact the sender via official channels.
2. Enable Call and SMS Filtering
Use your phone’s built-in spam detection features or apps like Truecaller, Hiya, or SpamHound.
3. Install Apps from Trusted Sources Only
Only download from the Google Play Store or Apple App Store. Check developer names, reviews, and permissions.
4. Use Two-Factor Authentication (2FA)
Enable 2FA on all accounts, and opt for app-based 2FA like Google Authenticator instead of SMS where possible.
5. Monitor Account Activity
Keep an eye on banking and email accounts for unusual activity. Report anything suspicious immediately.
6. Keep Your Device Updated
Install the latest security patches and OS updates. Many vulnerabilities are exploited through outdated software.
7. Educate Yourself and Others
Awareness is your first line of defense. Share knowledge with friends, colleagues, and family.
Bonus Tips for Advanced Users
- Use a Mobile Security Suite (e.g., Bitdefender, Norton, or Kaspersky)
- Audit App Permissions regularly via your phone’s privacy settings
- Lock Your SIM with a PIN code via Settings
- Enable Remote Wipe in case your device is lost or stolen
Conclusion
Mobile scams aren’t going away—but with vigilance and the right practices, you can dramatically reduce your risk. Whether it’s avoiding a fake delivery SMS or locking down your device, every action you take boosts your digital security.
