Many phones have pre-installed bloatware, including weather, music, or messaging apps. Keep in mind that you may not be able to remove these apps from your device.

Practice password hygiene

These days, giving someone your password is like giving someone the keys to your house. With so much sensitive information stored on our phones and online, a password is often the final line of defense between a hacker and your valuable data. 

Using strong passwords can stop hackers from taking over your digital life with password attacks. For extra security, be sure to change your passwords periodically, especially if you think your phone may be under attack.

Be sure to monitor your credit statements closely for the next year or two or even implement a credit freeze if you think your financial information was compromised.

Clear cache

To make your browsing experience quicker and more enjoyable, your phone temporarily stores data from the websites you visit. In case you’ve encountered any malware in your web browsing routine, clear your cookies and cache regularly.

Update the operating system

Updating your operating system (OS) is a great way to keep your device running smoothly. In addition to added features and bug fixes, these updates contain security patches to keep your phone secure. Just as you wouldn’t leave your door unlocked when you’re out of town, you shouldn’t leave your phone without proper security.

Uninstall jailbreaks 

People have been jailbreaking their phones and other devices for years. It allows you to customize your phone's features—at a cost. A jailbroken phone may be more vulnerable to cyberattacks and prevent you from updating your operating system, which often includes security patches that prevent zero-day exploits.

Complete a factory reset

If all else fails, you can perform a factory reset on your device. Before doing so, back up your important files, as a factory reset will wipe all of your files and personal data from your phone’s internal storage. On the plus side, a factory reset will also remove any malicious files a hacker may have been using.

Are you unsure if your phone was hacked? Luckily, these warning signs may help you figure it out. Let’s take a look at some of the most common red flags of a hacked phone.

Slower speeds

Once your device is under the control of a phone hacker, malicious applications may use up a large amount of its computing power. While it’s common for phones to slow down with time, malware can cause a sudden decrease in speed.

Shortened battery life

Hackers often use malware in fraudulent apps when breaking into your phone. These methods will use up a lot of your phone’s battery power, therefore shortening your battery life.

Frequent pop-ups

Combatting frequent pop-ups when browsing the web may be a sign your phone is under attack. Common examples of malicious pop-ups include: 

  • Notifications you’ve won a prize or contest
  • Fake virus alerts
  • Warnings that your personal information has been leaked 

If you see any of these pop-ups, close your browser immediately, because clicking on anything in the window may further expose your phone to cyberattacks.

Suspicious increase in data usage

Malicious applications are also known for their high data usage. Because these apps will constantly run when you’re under attack, you may notice a higher data usage on your monthly bill.

Unfamiliar apps

If you notice any new apps you don’t remember installing, your phone could be compromised. Many smartphone hackers rely on malware disguised as phone applications to trick users into giving up personal information.
