Unwanted WhatsApp Calls? How to Stop Spam and Fraud from +84, +62 Country Codes

WhatsApp is a convenient platform for communication, but its popularity has also made it a target for scammers. These scams are becoming increasingly sophisticated, often involving international calls, fraudulent messages, and fake job offers designed to steal money or sensitive information. In this detailed guide, we’ll delve into the nature of these scams, provide insights into their tactics, and equip you with advanced strategies to protect yourself and others.


Rise of International WhatsApp Scams

International scams on WhatsApp often start with calls or messages from unfamiliar country codes, such as +62 (Indonesia) or +84 (Vietnam). These numbers might seem random, but they are strategically chosen to exploit unsuspecting users. Scammers use psychological tactics to lure their targets with promises of financial rewards, such as lucrative job opportunities or payment for simple online tasks like liking YouTube videos.

How These Scams Work:

  1. Fake Job Offers: Scammers pose as recruiters, offering high-paying jobs or part-time tasks. Victims are often asked to pay a registration or joining fee, which is never refunded.
  2. Small Payouts to Build Trust: To appear legitimate, scammers may deposit a small amount into your bank account after an initial task. This tactic is used to lower your defenses and encourage further engagement.
  3. Disappearing After Payment: Once you’ve paid the requested fee or completed several tasks, the scammers typically cut all communication.

These tactics leverage trust and urgency, making it essential for users to recognize the signs of such schemes.

How to Handle Suspicious International Calls

Step 1: Identify and Block Suspicious Numbers

When you receive a call from an unfamiliar international number, especially those starting with codes like +62 or +84, it’s best to err on the side of caution. Blocking such numbers prevents further contact.

To block and report numbers:

  1. Open WhatsApp and select the chat with the suspicious number.
  2. Tap the three-dot menu at the top right.
  3. Select More > Block, then confirm the action.
  4. To report the number to WhatsApp, choose Report during this process.

Blocking and reporting help WhatsApp monitor suspicious activity and protect other users.


Step 2: Silence Unknown Callers

To minimize distractions and avoid interacting with unknown numbers, enable WhatsApp’s Silence Unknown Callers feature:

  1. Open WhatsApp, tap the three-dot menu, and go to Settings.
  2. Navigate to Privacy > Calls.
  3. Toggle on Silence Unknown Callers.

This setting ensures that calls from unknown numbers won’t ring on your device, allowing you to focus on more important matters.


Step 3: Restrict Group Additions

Scammers sometimes add users to dubious WhatsApp groups without their consent. Adjusting your group privacy settings can prevent this:

  1. Go to Settings > Privacy > Groups.
  2. Choose My Contacts to limit group additions to people in your contact list.

By taking this step, you’ll reduce the likelihood of being added to spam groups that could expose you to phishing links or other fraudulent activities.

1. Recognize Common Red Flags

Familiarize yourself with scam warning signs:

  • Too Good to Be True Offers: If the offer promises easy money or rewards for minimal effort, be skeptical.
  • Requests for Upfront Payments: Legitimate employers or organizations rarely ask for money before you’ve started working.
  • Generic Messages: Scammers often use copy-pasted or impersonal messages to target multiple users simultaneously.

2. Verify Unknown Links and Messages

Never click on links from unknown sources. Scammers often disguise malicious URLs as legitimate websites, leading to phishing pages designed to steal your login credentials or personal data.


3. Educate Yourself About Phishing and Social Engineering

Understanding common scam tactics is critical to staying ahead of fraudsters. Social engineering relies on manipulating human psychology, often using urgency or fear to pressure victims into action. By staying informed, you’ll be better equipped to spot and avoid these traps.


Reporting Fraud to Authorities and WhatsApp

If you suspect fraudulent activity, reporting it can help stop the scam and protect others:

  • To WhatsApp: Email their support team directly at [email protected] (for Android) or [email protected] (for iOS). Include screenshots and a description of the incident for a faster resolution.
  • To Authorities: Report scams to local law enforcement or a cybercrime division. In the United States, you can contact the Internet Crime Complaint Center (IC3) to file a detailed report.

Dealing with the Aftermath of a Scam

If you’ve already fallen victim to a scam, it’s crucial to act quickly:

  1. Contact Your Bank: Report unauthorized transactions and request a freeze on suspicious activity.
  2. Secure Your WhatsApp Account: Change your password and enable two-step verification to prevent unauthorized access.
  3. Spread Awareness: Inform friends and family about the scam to protect them from similar incidents.

How Scammers Exploit Personal Data on WhatsApp

Scammers rarely rely on brute force to access your data; instead, they use subtle methods to deceive you into sharing sensitive information. Here’s how they may exploit your personal data:

1. Social Engineering Tactics

Scammers use techniques that play on emotions such as trust, fear, or urgency. For instance:

  • They may impersonate legitimate organizations, such as government agencies or popular companies, and ask for sensitive details like passwords or identification numbers.
  • Messages often come with urgent language, such as “Your account will be suspended unless you verify your details within 24 hours.”

2. Phishing Links

Links sent by scammers may lead to:

  • Fake login pages designed to steal your credentials.
  • Malicious websites that download malware or spyware onto your device.
  • Survey scams that collect personal information under the guise of offering rewards.

3. WhatsApp Account Takeovers

Scammers may ask for your WhatsApp verification code under the pretense of a mistake. Sharing this code can allow them to take control of your account, giving them access to your chats and contacts.

How to Protect Yourself:

  • Never share your WhatsApp verification code with anyone.
  • Avoid responding to messages asking for personal details, even if they appear urgent or official.
  • Use tools like spam filters or URL checkers to assess whether a link is safe.

Differentiating Between Genuine and Fraudulent Job Offers

Fraudulent job offers are one of the most common WhatsApp scams. Here’s how to spot and avoid them:

1. Verifying the Legitimacy of the Employer

  • Check the Company’s Website: Legitimate companies typically have a professional website with clear contact information.
  • Search for Reviews: Look up the company on platforms like Glassdoor or LinkedIn to read employee reviews.
  • Contact the Company Directly: Reach out to the company using official contact information (not the details provided by the scammer) to verify the job offer.

2. Red Flags to Watch For

  • Upfront Fees: Genuine job offers never require payment for training, equipment, or placement.
  • Generic Job Descriptions: Scammers often use vague or too-good-to-be-true descriptions, such as “Earn $500 daily by working from home.”
  • High Pressure: If you’re asked to make immediate decisions without sufficient information, it’s likely a scam.

3. Protecting Your Information

  • Share your personal and financial information only after thoroughly verifying the recruiter and job offer.
  • Avoid sending documents like ID proofs or bank details to unverified contacts.

Advanced Online Security Measures

Beyond WhatsApp, it’s essential to enhance your overall online safety to protect yourself from potential scams across platforms. Here’s how:

1. Strengthen Your Passwords

  • Use unique passwords for all accounts. A strong password includes a mix of uppercase and lowercase letters, numbers, and special characters.
  • Consider using a password manager to store and generate secure passwords.

2. Enable Two-Factor Authentication (2FA)

  • Two-factor authentication adds an extra layer of security by requiring a secondary form of verification (like an SMS code or an authentication app) in addition to your password.
  • On WhatsApp, enable 2FA by going to Settings > Account > Two-step verification and setting a PIN.

3. Keep Software Updated

  • Regular updates patch vulnerabilities that hackers might exploit. Ensure your phone’s operating system and all apps are up to date.
  • Avoid using outdated devices that no longer receive security updates.

4. Install Reputable Security Software

  • Use antivirus and antimalware tools on your devices to detect and remove malicious software.
  • Regularly scan your device for threats.

5. Stay Educated About Scams

  • Keep yourself informed about the latest scam tactics and techniques.
  • Follow trusted online safety resources and participate in awareness programs, if available.

Reporting Scams to the Authorities

While reporting scams to WhatsApp is important, involving local and international authorities ensures broader action against scammers. Here’s how you can escalate issues:

1. Contact Cybercrime Divisions

  • In many countries, there are dedicated cybercrime units that handle online fraud cases. For instance:
    • In India, report to the Cyber Crime portal (cybercrime.gov.in).
    • In the US, file complaints with the Internet Crime Complaint Center (IC3).

2. Provide Detailed Evidence

  • Save screenshots of the fraudulent messages or calls.
  • Document all interactions, including any financial transactions.

3. Report Phishing Websites

  • Many governments and organizations allow users to report phishing websites for takedown. Look up local resources or contact your ISP for guidance.

Educating Your Friends and Family About WhatsApp Scams

Awareness is one of the most effective ways to combat scams. By sharing your knowledge, you can help others avoid falling victim. Here’s how to educate your loved ones:

1. Share Real-Life Examples

  • Discuss cases of WhatsApp scams you’ve encountered or heard about to make the risks relatable.
  • Explain how these scams operate, from fake job offers to phishing links.

2. Teach Safe Practices

  • Encourage them to block and report unknown numbers.
  • Show them how to enable two-step verification and other privacy settings on WhatsApp.

3. Distribute Informative Resources

  • Share trusted articles and guides, like this one, to enhance their understanding of online safety.
  • Recommend online courses or webinars on cybersecurity, if available.

Final Thoughts: Staying Ahead of Scammers

The digital world is constantly evolving, and so are the tactics of scammers. Staying vigilant, educating yourself, and taking proactive security measures are the best ways to protect yourself from fraud. By implementing these strategies, you can confidently navigate WhatsApp and other online platforms without falling prey to scams.
