Next time you get a missed call starting with +92; #90 or #09, don't show the courtesy of calling back. Some intelligence officials say that calling back these numbers could lead to your SIM card being cloned. BSNL is issuing alerts to subscribers — particularly about the series mentioned — above as the moment one press the call button after dialing the above number, someone at the other end will get your phone and SIM card cloned.
According to reports, more than one lakh subscribers have fallen prey to this new telecom terror attack as the frequency of such calls continues to grow. Intelligence agencies have reportedly confirmed to the service providers particularly in UP West telecom division that such a racket is not only under way but the menace is growing fast. "We are sure there must be some more similar combinations that the miscreants are using to clone the handsets and all the information stored in them," an intelligence officer told TOI.
General Manager (GM) BSNL, RV Verma, said the department had already issued alerts to all the broadband subscribers and now alert SMSes were being issued to other subscribers as well.
As per Rakshit Tandon, an IT expert who also teaches at the police academy (UP), the crooks can use other combination of numbers as well while making a call. "It is better not to respond to calls received from unusual calling numbers," says Tandon. "At the same time one should avoid storing specifics of their bank account, ATM/ Credit/Debit card numbers and passwords in their phone memory because if one falls a prey to such crooks then the moment your cell phone or sim are cloned, the data will be available to the crooks who can withdraw amount from your bank accounts as well," warns Punit Misra; an IT expert who also owns a consultancy in Lucknow.
The menace that threatens to steal the subscriber's information stored in the phone or external memory (sim, memory & data cards) has a very scary side as well. Once cloned, the culprits can well use the cloned copy to make calls to any number they wish to. This exposes the subscribers to the threat of their connection being used for terror calls. Though it will be established during the course of investigations that the cellphone has been cloned and misused elsewhere, it is sure to land the subscriber under quite some pressure till the time the fact about his or her phone being cloned and misused is established, intelligence sources said.
"It usually starts with a miss call from a number starting with + 92. The moment the subscriber calls back on the miss call, his or her cell phone is cloned. In case the subscribers takes the call before it is dropped as a miss call then the caller on the other end poses as a call center executive checking the connectivity and call flow of the particular service provider. The caller then asks the subscriber to press # 09 or # 90 call back on his number to establish that the connectivity to the subscriber was seamless," says a victim who reported the matter to the BSNL office at Moradabad last week. "The moment I redialed the caller number, my account balance lost a sum of money. Thereafter, in the three days that followed every time I got my cell phone recharged, the balance would be reduced to single digits within the next few minutes," she told the BSNL officials.
