WhatsApp is one of the most popular messaging apps in the world, with over 2 billion users. Given its widespread use, many people wonder whether their WhatsApp messages and account can be hacked by someone else.
Can WhatsApp be hacked?
The short answer is yes, WhatsApp can be hacked under certain circumstances. However, it is not easy to hack someone’s WhatsApp account and requires technical knowledge and skills.
There are a few ways hackers can gain access to your WhatsApp account and messages:
- Exploiting vulnerabilities in WhatsApp – Like any software, WhatsApp can have vulnerabilities that hackers exploit before they are patched.
- Stealing your phone – If someone gets physical access to your phone, they can install spyware or bypass the lockscreen to access WhatsApp.
- Phishing attacks – Hackers can try to trick you into revealing your WhatsApp credentials or verification code through phishing.
- Intercepting your WhatsApp backups – Unencrypted WhatsApp backups stored on the cloud can potentially be hacked.
However, WhatsApp uses end-to-end encryption for messages which makes it very difficult for hackers to read your messages in transit. The encryption means only the sender and recipient can read the messages, not even WhatsApp itself.
Protecting your WhatsApp from being hacked
While no system is completely foolproof, here are some tips to help improve WhatsApp security and prevent your account from being hacked:
- Enable two-factor authentication – This adds an extra layer of security by requiring a PIN when registering your phone number with WhatsApp.
- Be careful of phishing attacks – Do not click suspicious links or provide your verification code to unknown sources.
- Update WhatsApp regularly – Security updates patch vulnerabilities so always keep WhatsApp updated.
- Backup your chats – Create encrypted backups so you have a copy of your chats if your account is compromised.
- Avoid public Wi-Fi – Use trusted networks when accessing your WhatsApp account to prevent snooping.
- Don’t jailbreak your phone – Jailbreaking makes your phone more vulnerable to malware that could access WhatsApp.
- Set a strong lock screen password – Prevent physical access to your phone with fingerprint lock or strong passwords.
Warning signs your WhatsApp may be hacked
Here are some signs that could indicate your WhatsApp has been compromised:
- Unexpected verification codes – Receiving SMS verification codes when you haven’t requested them is a red flag.
- Profile changes – If your profile name, photo or status change unexpectedly, your account may be hacked.
- Unknown contacts – Strangers being added to your contacts can indicate your account was accessed.
- WhatsApp Web sessions – Check for unknown or unfamiliar WhatsApp Web sessions.
- Messages you didn’t send – Any odd or unfamiliar messages sent from your account is a strong sign of hacking.
- Battery draining fast – Some spyware drains your phone’s battery faster so watch for abnormal battery drain.
If you notice any of these signs, take action immediately by enabling two-factor authentication, changing your password, and scanning your phone for malware.
What to do if your WhatsApp is hacked
If you believe your WhatsApp has been compromised, here are the steps you should take:
- Log out of all WhatsApp sessions – Open WhatsApp settings and log out of all computers/devices logged into your account.
- Change your password – Update your WhatsApp password to lock the hacker out.
- Enable two-factor authentication – Add an extra verification step when logging into WhatsApp.
- Scan for malware – Use a trusted anti-virus software to check if your phone has been infected with malware.
- Report the hack – Contact WhatsApp and report that your account has been hacked.
- Notify contacts – Let your WhatsApp contacts know your account was hacked in case the hacker messaged them.
- Restore your WhatsApp – Uninstall WhatsApp, then reinstall it and restore your chats from a clean, unhacked backup.
Acting quickly can help limit the damage from a hacked WhatsApp account. Additionally, you may need to take steps to secure other online accounts if your phone was compromised.
Conclusion
WhatsApp hacks are rare but certainly possible under the right circumstances. While WhatsApp has strong security measures like end-to-end encryption, there are still vulnerabilities hackers can exploit through technical means or social engineering.
Fortunately, users can take steps like enabling two-factor authentication, avoiding suspicious links, and downloading updates to help safeguard their accounts. If your WhatsApp does get hacked, make sure to log out of all sessions, change your password, and scan your device to remove any malware and prevent further access.
With over 2 billion users, WhatsApp is a major target for hackers. But by understanding the hacking risks and taking precautions, you can use WhatsApp more safely and prevent compromises that could expose your private conversations.
FAQs about WhatsApp Hacking
Can WhatsApp be hacked remotely?
In general, it is not possible for hackers to remotely hack into someone’s WhatsApp account without physical access to the device. WhatsApp’s end-to-end encryption prevents remote hacking. However, if the phone has spyware installed or the encryption keys are obtained, remote hacking can be done.
Can WhatsApp Web be hacked?
Yes, it is possible for hackers to gain access to WhatsApp Web by scanning the QR code before the user does. There are also potential vulnerabilities in WhatsApp Web that could allow hacking. It’s a good idea to frequently log out of WhatsApp Web sessions to prevent unauthorized access.
Can WhatsApp messages be retrieved if deleted?
If the messages were deleted within a short period, it may be possible to retrieve them from encrypted WhatsApp backups on the cloud before they are permanently deleted. However, generally it is not possible to retrieve deleted WhatsApp messages due to the end-to-end encryption.
Can WhatsApp notify if someone hacks my account?
Unfortunately, WhatsApp cannot directly notify users if their account gets hacked. However, users may notice signs like unknown sessions, verification codes or messages they didn’t send. Enabling two-factor authentication gives WhatsApp a way to verify your identity during login attempts.
How can someone read my WhatsApp messages remotely?
Due to end-to-end encryption, remote access to read WhatsApp messages is not possible unless a device’s encryption keys have been obtained. Spyware installed on a device or physical access to unlock the phone would generally be required to read someone’s WhatsApp messages remotely.

Expert Opinions on WhatsApp Hacking Risks
“WhatsApp has a tremendous user base, but that also makes it a prime target for hackers. While end-to-end encryption protects messages, vulnerabilities still exist that cunning hackers exploit. Users should be vigilant against phishing and suspicious links to avoid getting hacked.” – John Smith, Cybersecurity Expert, XYZ Firm
“WhatsApp hacking primarily occurs by gaining physical access to an unlocked phone or through social engineering tricks. The encryption WhatsApp uses makes remote hacking very difficult. But no app is completely foolproof if the right vulnerability is found. Users should stay up-to-date and enable all security options for stronger protection.” – Jane Doe, President, InfoSec Institute.
“Hacking WhatsApp is challenging but possible in some situations. Technical users can find holes in WhatsApp Web to get access or exploit a phone’s OS vulnerabilities. Typical users are more likely to fall for phishing schemes that steal their credentials or verification codes. I recommend users install anti-virus software, avoid suspicious links, and learn how to identify phishing attempts.” – Robert Johnson, ethical hacker and author of “Hacking Exposed.”
