With
over two billion users globally, WhatsApp reigns as the world’s most popular
instant messaging app. In Malaysia, its dominance is even more pronounced, with
a staggering 89.3% of the population using it for daily communication, both
personal and professional. This widespread adoption, however, makes WhatsApp a
prime target for cybercriminals. The ease with which we connect on the platform
can also be its vulnerability, leaving users susceptible to various scams and
hacks. One of the biggest concerns? Not knowing for sure if the person on the
other end of the chat is truly who they claim to be.
As
of 2023, WhatsApp had 13.8 million users in Malaysia. In the same period, a
hacking community forum saw 11.7 million WhatsApp user details offered for
sale. It’s not a matter of if your WhatsApp will be hacked, but when
and how you’ll prepare for it.
The Danger of a Compromised WhatsApp Account
Unlike some other messaging apps that primarily reside within their own ecosystem, a compromised WhatsApp account can potentially grant hackers access to much more than just your chat history. In some cases, gaining control of your WhatsApp can be a gateway to broader control of your smartphone. This means hackers could potentially access your contacts, photos, emails, banking apps, and other sensitive data stored on your device. The implications are severe, ranging from identity theft and financial fraud to the spread of malware and misinformation.
Signs Your WhatsApp Might Be Hacked
Recognizing the signs of a compromised WhatsApp account is crucial for taking swift action. Here are some key indicators:
- Unusual Activity: Receiving messages from unknown contacts or from people you rarely communicate with can be a red flag. This could indicate that your account is being used to send spam or phishing messages.
- Sent Messages You Don’t Recognize: Regularly check your sent messages. If you find messages you didn’t send, it’s a strong sign that your account has been compromised.
- Unexpected Verification Codes: Receiving a WhatsApp verification code that you didn’t request is a major warning sign. This usually means someone is trying to access your account from another device. Never share this code with anyone.
- Unknown Linked Devices: WhatsApp’s “Linked Devices” feature allows you to use your account on multiple devices (like a computer via WhatsApp Web). Regularly check this section in your WhatsApp settings. If you see any devices you don’t recognize, remove them immediately.
Preventing WhatsApp Hacks: Proactive Measures
Prevention is always better than cure. Here are some proactive steps you can take to minimize your risk of being hacked:
- Be Wary of Forwarded Links: Exercise extreme caution when clicking on links forwarded through WhatsApp, especially from unknown sources. These links could lead to phishing websites or malware downloads.
- Enable Two-Factor Authentication (2FA): 2FA adds an extra layer of security by requiring a second form of verification (like a code sent to your phone) in addition to your password. 1 This makes it much harder for hackers to access your account, even if they have your SIM.
- Use the App Lock Feature: Most smartphones have a built-in app lock feature or allow you to download third-party app lockers. This requires a PIN, fingerprint, or facial recognition to open WhatsApp, adding another layer of defense.
- Install a Mobile Security Solution: Scan your mobile regularly with mobile security solution, such as Checkpoint Mobile Endpoint Security for malware.
What to Do if Your WhatsApp is Hacked: Immediate Action
If you suspect your WhatsApp account has been compromised, take these steps immediately:
- Open WhatsApp on Your Smartphone: Access WhatsApp directly from your phone (not a web browser).
- Delete Your Account: Navigate to Settings > Account > Delete my account. Enter your phone number in full international format (e.g., +60123456789) and confirm the deletion. This will log out the hacker from your account.
- Run a Malware Scan: Perform a full malware scan on your smartphone using a reputable antivirus app.
- Check for Unexpected Apps: Review the list of apps installed on your device and uninstall any you don’t recognize or that seem suspicious.
- Inform Your Contacts: Notify your friends and family that your WhatsApp account may have been compromised. This will alert them to be cautious of any suspicious messages they might receive from your account.
- Re-register Your WhatsApp Account: After deleting your account, you can re-register it using your phone number. This will create a fresh account, but be aware that your message history and backups will be lost unless you have a recent backup that predates the compromise.
By understanding the risks and taking proactive steps, you can significantly improve your WhatsApp security and protect yourself from potential threats. Stay vigilant, stay informed, and stay safe.
