Recently, Kathy S. addressed a concern that many of us can relate to: “I received calls from Beijing and Russia on my mobile phone. I did not answer them. Can you tell me why this is happening? Is my phone at risk?”

International call fraud on the rise
In recent years, international call fraud has become more common. One particularly common scam is known as “Wangiri,” which comes from Japan and means “one ring and a cut.” These scammers usually let the phone ring once or twice before hanging up, hoping to pique your curiosity and get you to call back.

HOW TO PROTECT YOUR IPHONE AND IPAD FROM HARMFUL APPS
Why are you getting these international scam calls?
There are several reasons why you may receive calls from unfamiliar international numbers.
Another scam: Scammers use automated systems to call thousands of numbers, disconnecting after one call. If you call back, you may be connected to a premium rate number, which will incur a significant charge.
Telemarketing and robocalls: Some companies use international numbers to circumvent local regulations and reach a wider audience.
Fake number: Scammers can make their calls appear to be from different countries, tricking you into answering.

Is your phone at risk?
While unexpected international calls don’t necessarily put your phone at immediate risk, there are a few potential dangers to be aware of. The main risk is potential financial loss if you interact with these scammers. If you call back, you may be connected to a premium rate service number belonging to the scammer. You may also be charged a lot for these calls, with the scammer looking to keep you in touch to increase the bill.
Although Wangiri scams are less common, there is always a risk of personal information being stolen when you interact with unknown callers. Sharing sensitive data, such as bank account numbers or social security numbers, can lead to identity theft.
If you answer or answer these calls, the scammers may report that your number is active, potentially leading to more scam calls in the future. Although not usually related to Wangiri scams, some sophisticated phone scams can potentially install malware on your device if you click on certain links, prompts or follow the scammer’s instructions.
The best way to protect yourself from malicious links that install malware, potentially accessing your private information, is to install antivirus software on all your devices. This protection can also alert you to phishing emails and ransomware scams, keeping your personal information and digital assets safe.

How to protect yourself
While these international calls may be a concern, there are steps you can take to protect yourself and your personal information. Here are six effective strategies to help protect yourself from potential scams and unwanted calls.
1) Do not answer or call back: If you receive a call from an unknown international number, refuse to answer the call or call back.
2) Block suspicious numbers: Use the phone’s built-in features to block these numbers and prevent future calls.
3) Report calls: Report these suspicious calls to your phone carrier and the Federal Communications Commission (FCC).
4) Use call blocking apps: Consider the possibility of installation call blocking apps to identify and block spam calls.
5) Be careful with personal information: Never share sensitive information over the phone, especially with strangers.
6) Invest in personal data removal services: Consider using services that remove your personal data from the Internet, reducing the chance of your information being obtained by fraudsters. While no service promises to remove all of your data from the Internet, having a removal service is great if you want to constantly monitor and automate the process of continuously removing your information from hundreds of sites over a longer period of time.
