Xiaomi Phone Hacked: How to Check, Delete Threats, and Protect Yourself in the Future

Have you noticed the strange behavior of a Xiaomi smartphone — fast battery drain, unfamiliar apps or suspicious activity on the network? Your device may have been hacked. In this article, we will discuss how to accurately determine the fact of compromise, remove malware and regain control of the device without losing data.

Xiaomi manufacturers regularly update their MIUI security, but even the most secure firmware doesn’t guarantee 100% protection from leaks, phishing or vulnerabilities in third-party applications. The main mistake users make is ignoring the first signs of hacking, which leads to theft of personal data, money from accounts or even remote management of the device. We have compiled expert recommendations relevant to models from Redmi Note 12 to Xiaomi 14 Ultra, taking into account the features of the latest versions of MIUI.

It's important to act quickly, but not panic. Some steps (like factory resets) can delete important files, so first we'll figure out how to save data and confirm that a hack has occurred. If you suspect that the phone is being used for surveillance or fraud, go to Emergency Responses.

Signs of hacking Xiaomi phone: how to recognize the threat

Malware and unauthorized access are different, and here are the key symptoms that should alert you:

• 🔋 Battery discharges in a few hours without active use – background malware processes consume resources.
• 📱 Unknown applications (such as Chinese or random names) appear – they cannot be removed in standard ways.
• 💰 SMS or push notifications about debits from bank cards tied to the phone.
• 📡 Mobile Internet traffic has increased – some viruses transmit data to remote servers.
• 🔒 Locking the screen or changing the password without your participation is a sign of remote control.

Pay special attention to MIUI settings: if you see programs with administrator rights that have not been installed in the Settings → Applications → Permissions section, this is a sure sign of compromise. Also check the Settings → Accounts and Synchronization: Unknown accounts (for example, Mi Cloud with someone else’s email) may indicate hacking.

Not all symptoms are definitively indicative of a break-in, for example, rapid battery drain can be caused by battery wear and strange applications by remnants of previous firmware. To confirm the threat, proceed to the next section.

How to check Xiaomi for viruses and malware

Use a combination of built-in MIUI tools and third-party antiviruses to diagnose your diagnosis. Start with standard tools:

1. MIUI Security Scanner: Go to Settings → Memory → Security Check. Run a full scan. Pay attention to warnings about “potentially dangerous” files.
2. Activity monitoring: Open Settings → Battery & Performance → Battery usage. Check which apps consume the most power in the background.
3. Journal of Network Activity: in Settings → SIM-maps and mobile networks → Data traffic see which programs were transmitting data without your knowledge.

If the built-in tools do not detect threats, install specialized antiviruses:

• 🛡️ Malwarebytes – detects spyware and Trojans.
• 🔍 Kaspersky Mobile Antivirus – effective against phishing and rootkits.
• 📱 Bitdefender Mobile Security – scans system files MIUI nucleus-level.

💡

Before installing the antivirus, turn off battery optimization for it in the MIUI settings. Otherwise, the system may pause scanning in the background.

Note that some viruses disguise themselves as system processes (e.g. com.android.system). If antivirus detects a threat in such files, do not manually delete them, which can cause system failure.

Emergency measures: what to do if the phone is hacked

If you have confirmed the fact of hacking, act on the algorithm:

Step 1. Isolate the device

Disable your mobile data and Wi-Fi immediately to stop the data being transmitted to intruders. If the phone is connected to Mi Band or other Xiaomi devices, untie them in the Mi Home app.

Step 2: Remove the back door

Go to Settings → Applications → Application Management and uninstall any suspicious programs. Pay attention to applications with device administrator or special access rights – they must be disabled in the appropriate settings sections.

⚠️ Warning: Some viruses block access to settings. If you can't open the app menu, go straight to reset settings via Recovery Mode.

Step 3: Reset to factory settings

This is the most reliable way to remove any trace of a break-in.

• 📱 Through the menu: Settings → The phone. → Resetting settings → Erase all data.
• 🔧 Using Recovery Mode: Turn off your phone, press the Power button + Volume up, select Wipe Data.

After reset, do not restore data from backups created before the hack – they may contain malware. Use only verified sources (for example, photos from Google Photos).

How to recover data after a hack without risking a second threat

If you didn't back up before the hack, you can partially restore the data.

If you need to recover files from your phone’s internal memory (such as documents or music), use Dr.Fone or EaseUS MobiSaver, but pre-scan them with an antivirus. Do not connect your phone to your computer without first checking – some viruses spread through your computer. MTP-connection.

Once you recover your data, make sure to change all passwords (email, social media, banking apps) and enable two-factor authentication. Use password managers like Bitwarden or 1Password to avoid being hacked again through credentials leaks.

How to protect Xiaomi from hacking in the future: prevention

To minimize the risks, follow these rules:

• 🔐 Turn off the debugging. USB In Settings → The phone. → Version. MIUI (7 times press) → Developer parameters → Debugging by USB. This feature is often used to install malware.
• 🛡️ Install real-time antivirus software (e.g. Avast Mobile Security or Norton 360).
• 🔄 Update regularly MIUI — New versions close vulnerabilities. Check for updates in Settings → The phone. → Updating the system.
• 📱 Don't install it. APK Even if the file is downloaded from the forum 4PDA, Check its hash amount (for example, via VirusTotal).
• 🔒 Use bootloader lock. On Xiaomi models with unlocked bootloader, it is easier to install malicious firmware. To block: go to Fastboot Mode. + Volume down) and execute the command fastboot oem lock

Pay special attention to the settings of the Mi Cloud:

• Turn off automatic sync for unnecessary data (such as Notes or Call Records).
• Enable notifications about new devices in your account (Mi Cloud Settings → Security → Sign-in Notifications).
• Check the list of connected devices in your Mi Account regularly.

💡

Even if you don’t notice signs of hacking, check your phone every 3 months with an antivirus and analyze network activity in your MIUI settings.

If you frequently connect to public Wi-Fi (such as at cafes or airports), use a VPN (such as ProtonVPN or Windscribe) to protect your traffic from being intercepted through vulnerabilities in routers.

What to do if a breach involves theft of money or data

If the hack has resulted in financial losses or personal information leakage, proceed with this plan:

1. Block bank cards linked to Google Pay, Mi Pay or SMS-Contact the bank and report fraud, and in some cases, you can cancel the transaction within 24 hours.

⚠️ Warning: Fraudsters may contact you under the guise of Xiaomi or bank support, offering "help" in refunding money. SMS or access to the phone via TeamViewer!

Xiaomi’s Vulnerabilities: What to Look for

Xiaomi devices have features that are often used by attackers:

• 📡 Vulnerabilities in Mi Wi-Fi Repeater: If you use your phone as an access point, update your router's firmware. In 2023, a flaw was discovered that allowed you to connect to the network without a password.
• 🔑 Mi Account problems: Xiaomi accounts are often hacked through phishing sites (such as fake Mi Cloud login pages). URL login.

If you use Xiaomi with custom firmware (like LineageOS or Pixel Experience), check it regularly for vulnerabilities through XDA Labs or GitHub, some of which disable the built-in MIUI security mechanisms, making it easier for attackers to do so.

For models with an infrared port (such as the Redmi Note 11 or POCO X5), disable Remote Control in the IR transmitter settings. In 2022, a vulnerability was discovered that allows you to send commands to your phone via an IR signal.
