Cybercriminals are constantly evolving and developing shrewd techniques to access your phone with your permission (unbeknownst to you). Yes, you read that right! Most of the time it’s you who allow threat actors to gain unauthorised access to your phone by clicking unverified links sent via texts, WhatsApp messages, and emails – or simply by granting permission to cloned apps.
 

Some of the common mobile malware are RAT (Remote Access Trojans), spyware, adware, crypto mining malware, etc. Let’s explore how these illicitv emenets can adversely compromise your digital privacy through your phone.
 

1. Personal data and credential theft: Mobile malware poses a serious risk to confidentiality by stealing personal data like contacts, messages, and passwords. Cybercriminals exploit this information for identity theft, fraud, and unauthorised access, causing long-term privacy and security issues.
    
2. Financial risks: Online financial scams are increasing at an alarming rate and usually it’s because of users’ ignorance or unawareness. Most of the time, users fall prey to such scams by ignorantly downloading cloned apps that replicate legitimate apps. This is how cybercriminals violate your digital privacy to steal credentials like credit card details, contact numbers, and so on. Put simply, they take control of your phone and can even drain your bank accounts and wallets.
    
3. Organisational risks: Using your compromised phones in an organisational network can lead to serious consequences like data breaches, loss of customer data, and more. The entire operation cycle might get disrupted, and worse, the organisation might have to suffer mammoth financial loss and irreversible reputation damage.

This is one of the most common signs to detect during a malware scan Android. These intrusive ads are designed to generate revenue through clicks, lead you to scammy offers, or even expose you to more dangerous malware. Stay cautious and avoid blind clicking.
    
2. Unexpected Billing:
   Go through your phone or credit card bills line by line. Scan for unauthorised services tacked onto your phone bill. If there’s something you can’t explain, it might be a cramming scam. Sadly, there have been cases where carriers didn’t address this properly, leaving the responsibility on you to identify and report fraudulent fees.
    
3. Sudden Dip in Battery Life:
   If your phone’s battery starts dying quicker than usual without any major changes – it might be because of malware running in the background or overusing your device’s components.
    
4. Phone too Hot to Handle:
   If your phone feels hotter than usual, it could be a sign of trouble, possibly caused by malware like Loapi. This type of software can overwork your phone’s CPU and charging components, leading to serious overheating issues. To stay safe, unplug it, turn it off, and let it cool down. A hot phone isn’t just uncomfortable, it can also be dangerous.
    
5. Phone Acting Sluggish:
   When a device gets infected with malware, it can push its hardware to the limit, leading to longer load times and frequent freezes. While some issues have been linked to playful pranks like text strings or wallpaper glitches, a sudden drop in speed might point to a deeper security issue.
    
6. Unknown Apps Popping:
