Do not just accept calls from foreign numbers, especially those from abroad. What's more, until you call back, the pulse can be sucked out!
This scam is known as Wangiri (from Japanese meaning ring once and then stop) and has been defrauding many people in the world for a long time. The mode is like this, the victim will receive a misscall and then call back to that number. Once picked up, the real person as an imposter or Interactive Voice Response (IVR) will make that person spend as long as possible staying on the line.
Launching Make Use of, Wangiri is one of the top five fraud methods used by fraudsters around the world. Wangiri carries significant financial risks for telephone companies and users, even losses from Wangiri fraud and other International Revenue Sharing Fraud (IRSF) have reached more than USD 27 billion or around Rp. 407 trillion more.
Unfortunately, Wangiri is difficult to eradicate. There are no regulations governing and targeting fraud with similar methods. In addition, Wangiri scams often use international telephone calls, which are difficult to trace.
Fortunately, we can prevent being fooled by Wangiri. The first way is to do a search on the foreign number that called your device on Google. Usually, scammers will use a number that looks like a local number to trick potential victims.
Next, use an application that can identify the identity of the caller. Currently there are many applications that offer these services such as GetContact, Truecaller, and Should I Answer. Last but very important: never share your phone number online. Not on social media or discussion forums.
So, that's about fraud under the guise of overseas calls. Do not fall for the trap, you.
