Your Xiaomi Redmi 8 Pro suddenly started to run out in a few hours, although it used to hold a charge for a day? apps themselves open at night, and mobile traffic melts away from scratch? These symptoms may indicate the operation of spyware β programs that steal data, track location or eavesdrop on conversations.In 2023, Kasperskyβs lab recorded a 37% increase in mobile spies compared to 2022, and Xiaomi devices due to open architecture. MIUI They are at risk more often than others.
Here are 7 proven ways to detect and remove a spy with Redmi 8 Pro, including hidden methods that are not written about in standard instructions. We're going to take a look at both system tools and third-party utilities, and we're going to show you which files and processes you want to check first on that particular model. MIUI (For example, com.miui.analytics), so a conventional antivirus check will not find them.
1. Signs of Spyware Infection on Redmi 8 Pro
Spyware programs rarely pose as symptoms, and they are meant to go unnoticed. However, there are specific signs on the Redmi 8 Pro that should alert you:
- π A sharp drop in autonomy: if the phone used to hold 1.5-2 days, and now discharges in 8-10 hours under normal use, check Settings β Battery. β Battery use: Spies often masquerade as processes like the Android System or Mediaserver, consuming 15 to 25 percent of the charge.
- π‘ Unexplained traffic consumption: open Settings β SIM cards and mobile networks β Traffic consumption and you see that it took 200-500 MB per night? This is a classic sign of data transfer (call logs, SMS, geolocation).
- π Extraneous sounds during calls: If the interlocutor complains of echoes or noise in the tube, it is possible that the recording of conversations works (spies like FlexiSPY or mSpy use the microphone even when the screen is off).
- π± Spontaneous actions: the phone restarts at night, the camera turns on without your participation, or in Settings β Apps appear unknown programs with Chinese characters in the title.
The Redmi 8 Pro features the Snapdragon 665 and 6GB of RAM, which allows spies to work in the background for years without causing suspicion. For example, Cerberus (positioned as anti-theft) actually collects data on all user activities, and is deleted only through the use of a computer. ADB.
β οΈ Note: If the phone is rooted, spyware could have infiltrated the system files, in which case a simple firmware reflash won't help - you need a complete Fastboot cleanup.
| Symptoms. | Probable cause | What do you do? |
|---|---|---|
| The phone is warming up without loading | Spy uses it CPU Encrypt data before sending | Check the Settings. β The phone. β System status for unknown processes |
| SMS confirming to unknown numbers | Interception SMS Two-factor authentication (e.g., Pegasus) | Turn off the shipment. SMS through settings β Passwords and security |
| Photos/videos disappear from the gallery | Spy copying media files to a remote server | Check the folder. /data/media/0/DCIM/.thumbnails hidden-file |
| The phone is slowly switched on (30)+ seconds) | The bootloader checks the connection to the C&C server (the spy command center) | Launch your phone in Safe Mode (hold the power button for 10 seconds) |
Verification through system tools MIUI
Redmi 8 Pro has built-in security features to help identify suspicious activity, starting with them β itβs safe and doesnβt require third-party software installation.
Step 1: Analysis of battery consumption
Go to Settings. β Battery. β Battery usage and sort the list by activity time:
- π Processes called com.android. or miui. that last longer than the screen was turned on.
- π Consumption annexes >5% of the battery you havenβt installed (e.g. com.sec.android.app.launcher is not a system app for Xiaomi).
Step 2: Monitoring traffic
Open the Settings. β SIM cards and mobile networks β Traffic consumption. It's important:
- π See which apps used traffic in the background (Background Traffic tab").
- π Check for System Updates β If they are consuming >100MB a month, maybe it's a spy disguise.
Step 3: List of installed applications
Go to Settings β Applications β Application Management and:
- Click on the three dots in the upper right corner β Show system processes.
- Note apps with a date that was not installed (for example, if the phone was purchased a month ago and the program was installed 2 weeks ago).
- Check applications with device administrator rights (the "Special Access" tab).
Sort applications by working time in the background|See the traffic consumption of the last 7 days|Find programs with administrator rights|Check the folder. /data/app unknown APK-->
On the Redmi 8 Pro, spies are often disguised as:
- π¦ com.miui.analytics (Xiaomi Analytics, but can be replaced)
- π¦ com.android.providers.downloads.ui (download manager)
- π¦ com.qualcomm.qti.autoregistration (system process, but may contain backdoor)
β οΈ Note: Do not remove system applications through Settings β Apps -- this can cause a phone to break down. Use only proven methods of uninstallation.
3. Search for spyware through ADB
If the system tools didnβt show anything, but suspicions remain, use Android Debug Bridge (ADB) β This is a low-level access tool, and it requires you to connect your phone to your PC, but it can even find deep-hidden spies.
What you need:
- π» Computer with Windows/Linux/macOS
- π USB-cable (preferably original from Xiaomi)
- π₯ ADB Fastboot Tools by Google
Step-by-step:
- Turn on the phone Developer Mode: go to Settings β About Phone and 7 times click on the MIUI version.
- Return to Settings β Additional β For developers and enable USB debugging.
- Connect the phone to the PC and in the command line enter: Adb devices Should appear device with a serial number.
- Use the command to search for suspicious packages: adb shell pm list packages -f | findstr "spy\|track\|monitor\|"Stealth" (for Linux/macOS Use grep instead of findstr)
- Check the list of installed services: adb shell dumpsys package | findstr "com.android"
If you see a package like this:
- π΅οΈ com.spymaster.pro
- π΅οΈ com.stealthgenie
- π΅οΈ com.flexispy
It's 100% spyware, and you can remove it by command:
adb uninstall --user 0 name packageπ‘
Before use ADB Create a backup of data through Settings β System system β Backup. Some commands can cause file loss.
4. Security scanners: which ones work on the Redmi 8 Pro
Antiviruses don't always detect spies, but some specialized utilities can help. 8 Pro due to modified firmware MIUI 12/13 Many antiviruses give false positives to system files.
Recommended programmes:
| Annex | What's he looking for? | Features for Xiaomi |
|---|---|---|
| Malwarebytes | Spies, keyloggers, backdoors. | We need to turn off optimization. MIUI battery-setting |
| Kaspersky Mobile | Advanced Spy (Pegasus, Predator) | It can be a problem with Google Play Protect. |
| iSpyoo Detector | Specialized spy detector | Demands a license. ADB deep-check |
| CertiK OS | System Vulnerabilities Through Which Spies Are Installed | It only works on unrooted devices. |
How to properly scan:
- Install one of the applications (not several at once β they may conflict).
- Before scanning, restart your phone in Safe Mode (hold the power button). β "Restarting in Safe Mode").
- Start a deep scan (not fast!).
- If you find threats of the RiskWare or Monitor class, remove them without hesitation.
On the Redmi 8 Pro, false positives often give:
- π« com.miui.securitycenter (Xiaomi Security Center)
- π« com.android.vending (Google Play Store)
- π« com.qualcomm.qcr (processor drivers)

5. Manual inspection of the file system
Spyware leaves traces in system folders. On Redmi 8 Pro, check the following directories (use a file manager with root rights, for example, the following directories, FX Explorer or Solid Explorer):
Key folders to check:
- π /data/app/ β stored APK Look for files with a change date that doesn't match the application installation date.
- π /data/data/ β Spies often create folders with random names like com.a1b2.c3d4.
- π /system/priv-app/ β If there's new files here after you bought your phone, it's suspicious.
- π /sdcard/.nomedia/ β hidden folder where spies put logs and screenshots.
How to find:
- Open the file manager and enable the display of hidden files (in the settings).
- Sort files by date of change β spies often update their modules every few days.
- Pay attention to files with extensions: π.dex (executable Android code) π.So (libraries, may contain malicious code) π.db (databases where stolen items are stored) SMS/contact)
Examples of suspicious files on Redmi 8 Pro:
- π /data/data/com.android.providers.telephony/databases/mmssms.db β size >5 MB, maybe there's a copy of yours. SMS.
- π /sdcard/Download/.temp/apk β There are often spies installers.
- π /system/bin/debuggerd64 β modified version of the system debugger.
β οΈ Note: Do not delete files from folders /system/ or /vendor/ without backup β this can lead to loss IMEI or sensory problems.

6. Checking network activity
Spyware communicates with command servers (C&Cs), so it can be computed over network connections. There are two ways to do this on the Redmi 8 Pro:
Method 1. Through the built-in traffic monitor
- Go to Settings β SIM cards and mobile networks β Traffic consumption.
- Press three points. β Using App Traffic.
- Pay attention to programs that transmit data to unknowns. IP-addresses (e.g. 185... or 91...).
Method 2. via Wireshark (for advanced)
If you have access to a PC:
- Connect the Redmi 8 Pro to the same Wi-Fi network as your computer.
- Start Wireshark and start packet capture.
- Filter traffic by IP phone (you can find out in the settings) β The phone. β Status).
- Look for connections to domains like: π spyserver[.]net π track[.]mobi π flexispy[.]com
On Redmi 8 Pro, spies often use ports:
- π 443 (HTTPS, masquerading as normal traffic)
- π 8080 (proxy servers)
- π 53 (DNS-tunneling)
If you find suspicious connections, block them through Settings. β Wi-Fi β Additionally. β Network management, by adding IP blacklisted.
π‘
Android spies often use legitimate services (such as Firebase or Android Spyware). AWS) If you see a permanent connection to googleapis.com or amazonaws.com without your actions, that's a reason to check.
7 What to do if a spy is found
You find spyware? You use an algorithm.
Step 1. Isolate your phone.
- π΅ Turn off mobile network and Wi-Fi.
- π Get out. SIM-card (if the spy intercepts the card) SMS).
- βοΈ Turn on Airplane Mode.
Step 2. Remove the spy.
Depending on the type of software:
- ποΈ Normal App: Remove via Settings β Annexes.
- π₯οΈ System spy: use it ADB (team adb uninstall --user 0 packet).
- π§ Spy with root rights: Reflashing through Fastboot is required.
Step 3. Restore security.
- Change all passwords (social networks, banks, mail).
- Enable two-factor authentication wherever possible.
- Install Google Authenticator instead of SMS-confirmation.
- Check the Settings. β Google β Account management β Security for Unknown Devices.
Step 4: Prevention
- π Disable the installation from unknown sources (Settings) β Privacy β Unknown sources).
- π‘οΈ Install NetGuard to monitor application network activity.
- π Check your phone regularly for viruses (once a month).
β οΈ Note: If the spy was installed through physical access to the phone (for example, someone took it in their hands for 5-10 minutes), chances are that it is embedded in the firmware.
