How to know if the phone is hacked?

Hackers can get into your phone, install malware, and access personal data by “hacking” the lock screen.

You’ve probably heard the term “screen hack (touch)” but don’t really understand it.

This is a form of cyber attack in which hackers covertly take control of the touch screen of a victim’s smartphone or computer. From there, they can perform various malicious tasks or access sensitive information such as account names, passwords, etc.

TRICKS OF NEWS

Screen hacking is usually done by taking advantage of a feature on the touch screen of electronic devices.

Hackers can access the victim’s screen remotely. To do that, they exploit the process of electromagnetic interference (EMI) – the process by which electrical signals can be detected and controlled. Because they contain many types of electrical signals, touch screen devices are susceptible to EMI.

Taking advantage of this connection, hackers can remotely insert fake touch points into your phone’s touchscreen, and then control the device without touching it directly.

After gaining access to your screen, they can change your lock screen password, install malware. They can even use this method to make purchases or access financial accounts without the victim’s knowledge.

Sequence of Attacks

Here are the steps that hackers usually take to successfully hack the victim’s touch screen.

Step 1: Find the right place.

Hackers will look for a public place where there are many “prey” and easy to act. For example an airport lounge, a coffee shop, a library or even on a train. In places like this, they can use EMI to access the touch screens of phones that are placed face down on a table.

Step 2: Install EMI . device

After finding a suitable location, the attackers will begin to install the EMI device. The device consists of an antenna and an amplifier, which generates magnetic signals, which can interfere with the electromagnetic field of the target touch screen.

Step 3: Transmit electromagnetic signals

Electromagnetic waves at specific frequencies are sent by hackers to interfere with the signals in your touch screen, thereby creating manipulations on the screen to gain control.

Step 4: Access the device

Once they have interfered with the electromagnetic field of the target device, the attackers will access and take control of the device, then perform malicious tasks.

HOW TO KNOW HACKED SCREEN?

It is very difficult to detect a hacked screen in the early stages because the hacker does not leave any physical traces. However, there are some warning signs that you can watch out for.

For example, when installing a new device, users tend to come up with their own preferences. If you notice any changes to the settings you previously selected, it could be a sign that your device is under attack.

Similarly, if you detect any unusual messages or calls coming from your phone, chances are, hackers have infiltrated your device.

Besides, screen hackers often use large amounts of data to control the device. Therefore, if you notice unusually high data usage on your phone, it’s likely that it has malware installed.

Finally, if your device connects to an unknown Bluetooth device, it could also be a sign of a screen hacking attack.

METHODS OF SAFETY GUARANTEE

Considering how dangerous screen hacking attacks are, experts recommend that you follow some of the tips below to protect yourself and your device.

Use a secure unlock method

If your phone supports fingerprint or face authentication, use these two methods instead of PIN or picture unlock.

Turn on 2-factor authentication

Two-factor authentication (2FA) provides an extra layer of protection for your device. In addition to the password, this method requires you to enter a code sent to the device or registered phone number to be able to log in.

2FA helps ensure that, even if someone gets your password, they can’t access it without the additional code.

Be careful in public

When in public, keep your phone out of sight and unattended.

Use a non-magnetic case

When using your smartphone, tablet or laptop in public, you should consider investing in non-magnetic cases/covers. This will help protect your device from malicious actors trying to gain control.
