Since 2023, the phone hacking incidents have surged by 300%, according to cybersecurity experts, which has made the topic more critical than ever. The signs of being hacked are if you experience suspicious behaviour on your phone, or want to know the whole process in order to stay ahead of threats. This complete guide will provide you with expert-level detection and emergency response strategies.  

Can Someone Actually Hack My Phone? The Shocking Reality

Absolutely, your phone can be hacked even without your knowledge. Cybercriminals have developed unique methods to compromise all devices, including Android devices and iPhones. Although Apple devices are considered more secure than Android devices due to their closed ecosystem architecture. 

Most Common Phone Hacking Techniques:

With the rise of technology, hackers also started to use new and unique ways to hack devices. Some of the casual ways hackers use to attack users are given below.

• Social Engineering Attacks: On social platforms or through emails and text messages, the attacker lures the user to click on certain links. When the user clicks on the malicious link, it directs the user to download the fake apps that result in hacking.  

• SIM Swapping: This is another technique used by hackers; they request the mobile carrier to transfer the user’s phone number to their devices. They use the phone number to gain the two-factor authentication code and many other account recovery options.  

• Malicious Public Networks: When someone is outside the home or office and runs out of data, they try to find a public network for a while. Hackers create fake networks. When users connect to those compromised public networks, they are trapped in digital traps. Then start intercepting the transmission of the user’s data.  

• Infected Charging Infrastructure: Using the charging cables at the public charging stations of unauthorized net cafes can harbor malware that is designed to steal the user’s data through the USB port of the mobile during the charging sessions. The user thinks the phone is being charged, but actually, the hacker is stealing the user’s data.  

• Third-Party App Store Exploitation: Mostly, hackers upload malware-infected apps as legitimate software, sometimes mimicking the brands to convince the users to install the unofficial app.  

If a hacker gained access to the sensitive information of the user, including the passwords, financial information, photos, and private communications. The user can be blackmailed by the hackers and may demand a significant amount by threatening them to expose the data to the public.  

6 Definitive Signs Your Phone Is Hacked (Don’t Ignore These Red Flags)

A vigilant observation is required to check the compromised phone. If you found the unusual activity or the symptoms that don’t usually appear, and subtle signs are often overlooked. For you, 6 signs are given below to check whether significant damage has occurred or not.  

1. Suspicious Battery Drain and Overheating Issues

What to Watch For: Fast draining of the battery is also a suspicious sign if you notice the fast battery drain or excessive heat generated during the light activities.  

Why This Happens: When a device is affected by the viruses, the malware and spyware start to run continuously in the background. This unwanted running in the background results in consuming more power while transmitting the data to the remote servers.  

Expert Tip: You should visit the settings of the device and measure the battery usage by the order of battery usage by the apps. If you monitored the new app in the list or any other suspicious application, this is a sign of potential security breaches.  

2. Unexplained Phone Bill Spikes and Data Usage

What to Watch For: One more step to measure the hacking is to monitor the data consumed and keep an eye on the monthly bills. If your device is hacked, the data will be transferred to the server, which uses the data to transfer users’ information to the server. After noticing the change in monthly data bills, you can figure it out.  

Why This Happens: Hacked phones steal the user data and send it ot the remote destination, so it consumes the data that results in the bill spikes.  

Action Required: You should set the billing limits according to your usage. If the resources are overused, you may be notified about the usage alerts and better detect the anomalies immediately.  

3. Erratic App Behavior and Performance Issues

What to Watch For:

• Unknown applications appearing without installation
• Familiar apps loading slowly or crashing frequently
• Applications opening and closing independently
• Settings reverting to previous configurations unexpectedly

Why This Happens: Malware interferes with normal system operations, installs additional malicious software, and modifies existing applications to serve attacker objectives.

4. Rogue Notifications and Unauthorized Settings Changes

What to Watch For:

• Unexpected two-factor authentication codes for services you didn’t access
• Pop-up advertisements during normal phone usage
• Camera, microphone, or location permissions granted to unknown applications
• Security settings modified without your authorization

Critical Alert: Unrequested verification codes often indicate someone is attempting to access your accounts using your compromised device.

5. Account Lockouts and Authentication Problems

What to Watch For: If you notice a sudden logout from any of your accounts, as lost access to Apple ID, Google account, banking apps, or social media accounts, you should be worried about uncertain behavior.  

Why This Matters: This could be a sign of suspicious activity that happened to your account. All of the service providers,l ike Google or Apple, notify you by email or any other way added to the account for suspicious activity or password changes. If a hacker gained access to the user’s account, they could modify the credentials and steal sensitive information stored in the database.  

Immediate Response: If you noticed and it’s confirmed that you didn’t make these changes, you should contact a security expert or the related helpline of the affected service and initiate the account recovery procedures to secure your account or device.
