Keyloggers

• Keyloggers track and record every keystroke made on the device, capturing sensitive information such as passwords, credit card numbers, or messages. This data is often sent back to a remote server controlled by the attacker

​

SMS and Call Monitoring Spyware

• Spyware that intercepts SMS messages and call logs, allowing an attacker to view sent and received messages, listen to phone calls, or track who the user is communicating with.

• Some spyware infections can even forward calls or text messages to another number.

​

GPS Tracking Spyware

• GPS tracking apps can be installed to monitor a device’s real-time location. These apps can track your movements and report them to someone else without your knowledge.

• Some spyware also logs location history and shares it with the attacker.

​

Remote Access Tools (RATs)

• RATs (Remote Access Tools) allow someone to take over control of the mobile device remotely. This can include accessing the camera and microphone, reading messages, browsing files, or even taking screenshots.

​

Camera and Microphone Hijacking

• Certain spyware can gain control of the phone's camera or microphone, allowing the attacker to capture photos, videos, or audio recordings without the user’s consent.

• Always-on recording: In some cases, the microphone can be used to record conversations happening near the device, making it an effective eavesdropping tool.

​

Social Media Account Hijacking

• Some types of mobile spyware specifically target social media accounts. It may steal login credentials for platforms like Facebook, Instagram, or WhatsApp, allowing the attacker to impersonate the user, read private messages, or post on their behalf.

​

Email and Chat Spying

• Spyware can intercept email conversations and chat app messages (like WhatsApp, Signal, iMessage, etc.), even if the communication is supposed to be secure and encrypted.

​

Browser Activity Monitoring

• Spyware can track the user's browsing history, including sites visited, cookies, and saved passwords. Some spyware may also inject malicious ads or redirect the browser to phishing websites.

​

Data Exfiltration

• Some forms of spyware are designed to steal sensitive data like contacts, photos, files, and documents stored on the device. This information can be used for identity theft or financial fraud.

​

Hidden Apps and Processes

• Malicious apps may run in the background, hidden from the user’s app menu, and disguised under a different name to avoid detection. They consume resources and gather data in the background.

​

Battery Drain and Overheating

• Many types of phone spyware run continuously in the background, causing the device’s battery to drain faster than usual. Spyware may also result in the device overheating due to the constant activity it performs (e.g., sending data, accessing hardware components).

​

Abnormal Data Usage

• Phone Spyware often requires a lot of data to send information to a remote server. Unusually high data usage on the mobile plan can be a symptom of spyware sending information off the device without the user's knowledge.

 

Network & Traffic Manipulation

• Rogue VPNs/proxies, hostile/root CA certificates, “split-tunnel” data exfil.

• Malicious Wi-Fi profiles (evil-twin/auto-join), risky Bluetooth/BLE pairings/beacons.
