Bangladesh Telecommunication Regulatory Commission has initiated a move to strengthen its call-spoofing prevention measures.
Call spoofing, also known as caller ID spoofing, has frequently been used in recent days for fraudulent activities. The abuse causes the telephone network to give the receiver false information about the caller. Under the malpractice, criminals use others’ mobile numbers as a disguise to make phone calls.
BTRC sources said that a number of groups were active to claim extortion money and cheat people using call spoofing.
One of the groups claims money from the family members of missing persons for the persons’ safe return.
In July 14 this year, unidentified miscreants demanded money from two Chittagong City Corporation ward councillors through spoofing the official phone number of the deputy commissioner.
Keeping the issues in mind, the telecom regulator has taken a number of measures including investigating issues based on complaints from the victims, a senior official of the commission told New Age.
The commission detected that such activities were initiated from IP-based telephone services as such calls could not be generated through mobile phone technology.
Under the move, the BTRC has asked the mobile phone operators to take measures for the prevention of call spoofing.
At the same time, the commission asked all the mobile phone operators to inform the telecom regulator by September 22 this year about the measures the entities have taken so far in this regard.
Another BTRC official said that the international calls were another way of entering spoofed calls inside the country.
He said most of the incoming international calls were brought in Bangladesh through cheap international careers which did not follow country code-based phone call generation.
‘That’s why the country’s mobile phone operators along with other telephone operators are allowing such phone calls which do not match with the callers’ phone numbers,’ he said.
The commission is now thinking for alternatives to tackle such call and its misuse, the BTRC officials said.
They said that the telecom regulator refrained from blocking such calls as the incoming international call volume might decline if such calls were blocked.
