Smartphone threats are growing — how safe is your device?

Mobile security

It was long believed in cybersecurity circles that mobile devices were naturally more secure than traditional computers. Strict app store reviews, application sandboxing, and restricted file access made phones a tougher nut to crack. That assumption is rapidly becoming outdated.

Throughout 2025, reports from several threat intelligence firms showed a rise of over 50 percent in mobile malware infections compared to the year before. Modern smartphones store banking credentials, two-factor authentication tokens, medical records, and years' worth of personal photos. By every meaningful measure, they represent a prime target.

Today's most prevalent mobile threats

Rogue applications

Even with app store screening in place, harmful applications continue to slip through the cracks. Fake utility tools, counterfeit versions of popular games, and seemingly trustworthy apps have all been caught stealing contacts, intercepting text messages, or running hidden adware. The risk escalates significantly on Android when apps are sourced from unofficial stores.

SMS-based phishing (smishing)

Phishing via text message has now surpassed email phishing in sheer volume. A message posing as your bank, a delivery company, or a government body links you to a convincing replica website that harvests your login credentials. The abbreviated URLs and compact screens of mobile devices make these scams particularly difficult to recognise.

Open Wi-Fi risks

Joining an unsecured wireless network at an airport, hotel, or coffee shop puts your data within reach of anyone on the same network. Man-in-the-middle attacks — where a third party quietly reads and relays your data — are relatively simple to carry out on unprotected connections.

Monitoring software and spyware

Commercial surveillance apps, sometimes called stalkerware, can be planted on a phone with just a few minutes of physical access. Once active, they run invisibly in the background, logging conversations, calls, and GPS coordinates. Detecting them without a specialised security tool is extremely difficult.

Is mobile antivirus effective?

It is, with certain limitations. On Android, security apps can scan installed applications, warn about risky websites, highlight excessive permissions, and identify known spyware. iOS's closed ecosystem restricts deep scanning, but security apps still provide VPN protection, Safari-based phishing alerts, and notifications when your email address appears in a data breach.

Mobile antivirus is not a cure-all, but it meaningfully shrinks the attack surface — especially for Android users who obtain apps from various sources.

Steps you can take to secure your phone right now

  • Always keep your operating system and apps up to date
  • Download apps exclusively from official stores and review permissions before installing
  • Activate a VPN when connecting to public Wi-Fi
  • Turn on two-factor authentication for every important account
  • Use a trusted mobile security application and scan your device regularly
  • Treat any unsolicited text containing a link with suspicion

Final thoughts

The days of assuming your smartphone is safe by default are over. The combination of valuable personal data, constant connectivity, and ever-more-sophisticated attacks makes mobile security a necessity rather than a nice-to-have. An integrated security suite that covers both desktop and mobile is the most practical way to protect all your devices in 2026.
