The telecom regulator is facing caller ID spoofing or replication of its own numbers by scammers who are using the replicated numbers to trick mobile phone subscribers into giving them (criminals) their private and financial information.
The criminals are seeking the information through sending short messages and making calls on the pretext of needing the details to settle monetary rewards or to verify biometric registration of SIM cards.
Caller ID spoofing is a practice of hiding the number of call originator by replicating number of someone else.
The Bangladesh Telecommunication Regulatory Commission on Monday requested mobile phone subscribers to be cautious about such fraudulent activities.
Some groups are stealing private information of the subscribers using the name of BTRC, it said.
The private information includes SIM registration information and PIN number for mobile financial services.
In a public notice, the regulator said recently some scammers used BTRC landline number +88029611111 and mobile phone number +8801555121121 to conduct such crimes.
It said that mobile subscribers were also receiving SMS from IDs like BD info, Bangladesh info, BTRC info with request to share their information via SMS.
The notice also said that numbers of the private mobile phone operators were also used in such activities.
The BTRC also requested subscribers to report such scams by calling at 2872 or sending email to firstname.lastname@example.org.
‘It is to inform the subscribers that BTRC never asks for any personal detail of any subscriber through call or SMS. The mobile subscribers are advised not share such information with anyone,’ said the notice.
‘In the case of BTRC numbers, the biometric verification issue is being used
and people are falling victim of cheating,’ said a BTRC official.
Another BTRC official said that the regulator already started working on the matter with the help of mobile phone operators and the law enforcement agencies.
‘Most of the caller ID spoofing is done through computer software. This is very hard to trace as no traceable mobile number is there. The software creates the replicated number and enters into mobile network,’ another BTRC official said.
