A few weeks ago, while using my Samsung Galaxy S21, Android 13, I noticed something strange on WhatsApp. Messages I hadn’t sent were appearing in my chats, and some friends reported receiving weird links from my number. I immediately feared my WhatsApp account was compromised.
The thought of hackers having access to my chats, contacts, and even sensitive information was terrifying. I knew I needed a real solution — not just tips from blogs — so I decided to take action myself. After testing several methods, I successfully secured my WhatsApp account without losing any data.
Here’s my personal experience and the exact steps that worked.
Sign #1: Unexpected Messages or Activity
The first sign that my account was hacked was messages being sent without my knowledge. Some contacts received messages asking for money, while others got links I hadn’t shared.
Lesson:
Even if nothing seems wrong, if your friends report unusual activity, treat it as an urgent warning.
My action:
I immediately logged out of all WhatsApp web sessions:
-
WhatsApp → Settings → Linked Devices → Log out of all devices
This ensures hackers no longer have remote access.
Sign #2: Suspicious Login Notifications
WhatsApp often sends notifications when your account is accessed on a new device. I received a “New login” notification for a device I didn’t recognize.
My action:
-
Immediately enabled two-step verification (2FA)
-
Changed my account password for additional security
Step:
-
Settings → Account → Two-step verification → Enable
-
Set a strong 6-digit PIN and linked email for recovery
This added an extra layer of protection, making it nearly impossible for hackers to log in again.
Step 3: Check for WhatsApp Web Access
Hackers often use WhatsApp Web to control accounts remotely. I checked my linked devices:
-
Settings → Linked Devices
-
Found one suspicious device
-
Logged out immediately
Tip: Always check this list periodically to detect unauthorized access.
Step 4: Review Connected Apps
Some apps may have access to your WhatsApp or device data. I went to:
-
Settings → Apps → Permissions
-
Removed suspicious apps that requested SMS, contacts, or WhatsApp access
This prevents malware or third-party apps from exploiting your account.
Step 5: Secure Your Email
Many WhatsApp recovery and hacking attempts rely on email. I ensured my Gmail account was secure:
-
Changed my password to a strong, unique one
-
Enabled two-factor authentication
-
Checked account activity for unauthorized logins
By securing my email, I blocked a common pathway hackers use to take over accounts.
Step 6: Avoid Phishing Links
Hackers often send messages claiming:
-
“Your account is at risk, click here”
-
“You have a gift card or reward”
I received a few of these and did not click them.
Tip:
-
Always verify links independently
-
Never share the 6-digit WhatsApp verification code
Step 7: Scan Your Phone for Malware
Since my WhatsApp had unusual activity, I suspected malware on my Samsung Galaxy S21.
What I did:
-
Installed Malwarebytes for Android
-
Ran a full device scan
-
Removed suspicious apps and files
This ensured that hackers didn’t have a backdoor into my phone.
Step 8: Inform Contacts
Once I secured my account, I warned my contacts about potential scam messages they may have received from my number.
Tip:
-
Inform family, friends, and colleagues immediately
-
Advise them not to click any suspicious links sent from your number
Step 9: Monitor for Unusual Activity
For the next week, I actively monitored:
-
Sent messages for anything I didn’t send
-
Login notifications
-
Linked devices list
Regular monitoring helps detect new threats early before hackers can exploit them.
