How to Check Your Phone for Spyware
Would you know how to check your phone for spyware if you suspected you were being spied on? Smartphones are essential to our daily lives, serving as our wallets, calendars, communication hubs and vaults for personal information – but they’re often overlooked when it comes to understanding the risks of spyware and other malicious software. Our phones’ convenience is also what makes them prime targets for cybercriminals, and spyware – malicious software designed to spy on your activities – can easily turn your phone into a surveillance device, if given the chance.
In this blog we’ll cover how to detect spyware, how to remove spyware from smartphones, and other mobile security tips that can keep your phone (and everything you use it for) safe and secure.
Understanding spyware on mobile devices
It’s a common misconception that spyware only infects PCs and other desktop devices. While the built-in security in smartphones has gotten better and better over time, cybercriminals have also continued to develop more sophisticated ways of countering those defenses.
What Is spyware?
Spyware is a type of malicious software that secretly collects information from your device. It can monitor your calls, texts, browsing history, location, and even capture sensitive credentials such as your banking details and other passwords. Unlike some forms of malware, spyware is designed to operate discreetly, so that it can run in the background, unnoticed by the user, for as long as possible. This is one of the reasons why it’s so hard to detect spyware on phones and other devices.
There are various types of spyware, ranging from keyloggers to GPS tracking software. Some are tailored to target specific individuals, whereas others are used by organizations and governments for surveillance purposes.
How does spyware infect smartphones?
Spyware can infiltrate smartphones in several ways:
- Malicious apps, disguised as (or piggybacking on) legitimate apps or games, that infect your phone once installed.
- Phishing links designed to lead the user to accidentally installing the malicious software.
- Taking advantage of software vulnerabilities in outdated operating systems or apps.
- Infecting devices through unsecured or public Wi-Fi networks.
- Physical installation.
Understanding how spyware spreads is the first step to defending yourself from it. But how can you tell if your phone has already been compromised?
Signs that your phone may be infected with spyware
Spyware may be designed to operate covertly, but even the best spies have tells. Here are some of the ways to detect spyware on phones.
Unusual battery drain
Spyware constantly runs in the background, consuming your device’s resources such as CPU or GPS. This increased activity can sap your phone’s battery, and create a noticeable decrease in battery life. If you’ve noticed a change in the longevity of your phone’s battery life, it might be worth investigating further.
Increased data usage
Another red flag is unexplained spikes in your data usage. Spyware can transmit the data it steals back to its creator, but this requires significant bandwidth. Review your data usage regularly to spot any anomalies.
Slow performance and overheating
If your phone develops a habit of overheating, or is suddenly more sluggish than usual, spyware could be the cause. The constant background activity of malicious software puts a strain on hardware, leading to performance issues for your phone and frustration for you.
Strange behavior and notifications
Apps you don’t remember downloading, unexpected pop-ups, or texts from unknown sources could also indicate the presence of spyware. Similarly, if your phone makes unexplained calls, sends texts without your input, or experiences frequent crashes, it’s worth investigating further.
How to Check Your Phone for Spyware
If you suspect your phone might be compromised, follow these steps:
Review installed apps
Carefully examine your list of installed apps and their various permissions. Look for apps you don’t recognize or recall installing. Pay attention to apps with generic names, such as “System Update” or “Device Manager”. Research any suspicious apps you find online to see if they’ve been flagged by other users or cybersecurity experts.
Use safe mode
Booting your phone in safe mode disables third-party apps, making it easier to identify if a malicious app is causing the issue. For Android users, you can press and hold the power button until the Power Off option appears. Tap and hold Power Off, and the option for Safe Mode will appear.
Install security software
Comprehensive security software can detect and remove spyware, often identifying threats that are difficult to spot manually. Look for a reputable app from a trusted provider to scan your device – but avoid downloading free, unverified security apps that might be spyware in disguise.
Steps to remove spyware from smartphones
If you’ve managed to confirm the presence of spyware, taking action as soon as possible is crucial.
Uninstall suspicious apps
Remove any and all apps you’ve identified as being potential threats. Make sure that you’re fully uninstalling these apps, not just removing them from your homepage. After uninstalling, monitor your phone for signs of improvement in performance and behavior.
Perform a factory reset
If the spyware persists, or you haven’t been able to identify its origins, a factory reset is the most effective solution. This will restore your phone to its original settings, erasing all apps, data and malware. Back up any files you want to save, such as pictures and contact details, before proceeding
Install security software
After removing suspicious apps or resetting your phone, install a trusted security app to safeguard it against future threats. Choose software with real-time threat detection, regular updates, and robust privacy protections. And, for good measure, carry out a scan on your phone as soon as it’s installed to make sure you haven’t missed any potential threats.
Don’t let spies crack your smartphone safe
Your smartphone is a treasure trove of personal information, and keeping it secure should always be a top priority. Spyware is a hidden threat that can compromise your privacy, steal sensitive data, and disrupt your device’s performance. By understanding the risks, learning how to recognize the warning signs, and taking proactive steps, you can protect yourself from spyware and other cyber threats.
