Signs that your phone has been hacked.

Currently, many users are unaware that their mobile phones have been and are being hacked and their information exploited by cybercriminals. This can lead to many unforeseen risks.

Here are some signs that your phone has been hacked.

You've received calls and messages from an unknown number.

If you see a list of calls or messages to an unknown number, you should be wary because these could be foreign numbers used to steal telecommunications charges, along with malware forcing your phone to make calls.

Consequently, the hacker will steal your phone credit. In this case, users should check their phone balance to see if any unusual charges have been made.

Unusual activity on the account linked to the phone.

If hackers gain access to a user's phone, they also gain access to accounts on the phone such as social media, email, banking, etc.

Users can identify this based on account activity, such as password resets, sending emails, marking emails as unread, etc.

In this case, users may be at risk of identity fraud, as hackers could open new accounts or credit lines using stolen personal information.

The phone's battery drains quickly and it lags.

When smartphones are infected with malware, their lifespan is significantly reduced and the battery drains quickly. This malware consumes all of the phone's resources to scan the device and transmit information back to the hacker's server.

In addition, lag can be caused by overloading the phone's resources or conflicts with other applications due to malware.

Users may also encounter situations where apps continue running in the background even after trying to close them, or the phone shuts down or restarts repeatedly.

Unusual data usage for Wifi/3G/4G

Another sign that your phone has been hacked is that your Wi-Fi and 3G/4G data usage is excessive. Bandwidth is frequently congested, and web browsing is often slow, choppy, or laggy.

Mysterious pop-up windows

While not all pop-ups mean the phone has been hacked, persistent warnings may indicate that the user's phone has been infected with adware, a type of software that forces the device to view advertising websites.

Even if the pop-up window isn't the result of a compromised phone, many of the links are potentially phishing attempts to trick users into entering sensitive information or downloading more malware.

What should you do if your phone gets hacked?

If you suspect your phone has been hacked, you should perform a factory reset to ensure maximum security.

For Android, AnonyViet recommends using an app that can scan for malware, provides call blocking, firewall, VPN, and a PIN requirement for certain apps – preventing malware from opening sensitive applications like online banking apps, such as Kaspersky Mobile or Avast Mobile.

For iPhones, users should avoid jailbreaking (modifying the system configuration) as this increases the risk of being hacked.
