If you notice a spike in your data usage, it could be a red flag. Hackers may use your phone to transmit data, often without your knowledge, which can result in unexpected data overages.

Suspicious Texts or Calls

Have you received odd text messages or phone calls from unknown numbers or contacts claiming you've sent them messages you have no recollection of? This could be an indication that your phone has been compromised.

Unauthorized Access to Accounts

If you receive notifications about unauthorized access attempts or changes to your email, social media, or financial accounts, it's a strong indicator that someone has gained control of your phone.

2. Types of Phone Hacks

Understanding the various ways your phone can be compromised is essential for effective countermeasures. Here are the common types of phone hacks:

Malware Infections

Malware, short for malicious software, includes viruses, spyware, and Trojans that can infiltrate your phone through infected apps, emails, or websites. Once inside, malware can steal your data, monitor your activity, or even take control of your device.
