The Ministry of Information and Communications (MIC) has informed the public to be wary of incoming calls from overseas telephone numbers that could be scams or blackmail attempts.
According to Authority of Telecommunications (AoT), social network users have recently been receiving warnings about calls from overseas, including ones with the prefix +375 (Belarus) and +371 (Latvia). Users have been warned that if they call back, their contact lists and the details about bank accounts or credit cards may be copied within three seconds.
Users have been advised not to receive such calls, not to call back and not to press * # 90 or # 09 *.
AoT affirmed that these are spreading via social networks. in Vietnam, there is no call service in which receivers pay for calls (known as collect calls), including calls from overseas.
It also affirmed that if pressing * # 90 or # 09 * when answering the call, receivers’ information about credit cards and bank accounts will be stolen. It’s impossible to access users’ simcards even though someone implements such operations.
The agency has told users to be alert and not spread rumors which may cause anxiety to people. When getting a warning scam and unclear information shared on forums and social networks, users should report this to telecom carriers. After clarifying the information, they will give notices to subscribers.
There’re two possible scenarios. First, scam calls from overseas aim to entice receivers to call back and get hit with charges. The charge on the call to satellite phone numbers is VND99,000 per minute on average up to VND150,000 per minute.
Second, scammers call victims, introduce themselves as officers of electricity companies and inform victims that they owe electricity bills; impersonate a postman who informs them that they have gifts from overseas; acts as a banking officer who informs them that they have to pay bank debts; or acts as a policeman who informs them they have violated traffic laws or have relations with drug trafficking and international money laundry cases. The scammers may ask victims to declare their assets and bank accounts to appropriate their money.
The agency said despite regular warnings, many people have become the victims of the scams. It has told mobile network operators to apply technical solutions to prevent scam calls.
From July 2020 to September 2021, network operators prevented 74 million fake calls, including 3.5 million fake calls in September.
