WANGIRI FRAUD CALL

 

 

WHAT IS A “WANGIRI” SCAM

 

The wangiri phone scam is a scam where scammers call your mobile phone, which rings once, and hang up before you can pick it. This type of scam originated from Japan and hence the name Wangiri. It is also known as the “one ring and cut” scam – wan means “one” and giri means “hang up” in Japanese.

 

HOW WANGIRI WORKS

 

There has been a recent wangiri scam in Kenya that has been reported by users on social media. The scam/scheme is designed to lure innocent and unaware phone users to  returning the “urgent” international calls upon which they are unknowningly redirected to premium numbers that drain their credit.

 

During the calls, users are played for a recorded message so as to keep the caller on line. The longer the callers stays online, the more money the scammers make. In such a case, post-paid subscribers are likely to be unaware because they receive their bills at the end of the month. The pre-paid subscribers can only lose as much as their loaded credit.

 

In Kenya, the calls have been reported to be coming from numbers with the following codes: +41(Switzerland), +963(Syria) , +252(Somalia) or +37(Lativa). These numbers are bought by the scammers illegally from the dark web.

 

PROTECTING YOURSELF FROM WANGIRI

*       Don’t call back any international number that you don’t recognize.

*       If you happen to already be a victim, report the number to your service provider so that they can block the numbers. This stops other users from becoming victims.
