The Times of India (New Delhi edition) - - Times City - Caller ID spoof­ing al­lows one to dis­play a phone num­ber that is dif­fer­ent from the one be­ing ac­tu­ally used to make the call One can choose what num­ber and name will be visible to the re­cip­i­ent

be from a phone num­ber of the caller’s choos­ing.

Some­time ago, busi­ness­men had sim­i­larly re­ceived calls from the of­fice of Ka­mal Singh, the en­force­ment direc­torate chief. The caller claimed to be in­form­ing them about sum­mons is­sued to them for money laun­der­ing. The Spe­cial Cell probed this case too, but did not get far in un­rav­el­ling the mys­tery. They could only de­ter­mine that the calls had not orig­i­nated in the ED chief ’s of­fice. Sev­eral ar­rests have been made in re­cent months of peo­ple us­ing sim­i­lar tac­tics to ex­tort money.

Catch­ing these spoofers is tough, say po­lice. “The calls are mostly made us­ing in­ter­net tele­phony and trac­ing it over VOIP (voice over in­ter­net tele­phony) is very dif­fi­cult be­cause the caller’s IP ad­dress lies hid­den be­hind prox­ies,” ex­plained an of­fi­cer of the po­lice cy­ber cell. “The call­ers also use vir­tual pri­vate net­works to mask their iden­ti­ties.” Us­age of prox­ies can thwart all ef­forts of the cops.

If the num­ber is fa­mil­iar, but the caller isn’t, hang up and call back If the caller claims to be from a govt agency, call back to check Three west Delhi res­i­dents ar­rested for dup­ing some Aus­tralian res­i­dents, in­clud­ing ac­tress Isha Shar­vani, by pos­ing as of­fi­cials from Aus­tralian Tax Of­fice Uniden­ti­fied man spoofs num­ber of a Dubai busi­ness­man, makes hoax bomb call at a mall in Chandi­garh A 25-year-old man held for ex­tort­ing money from a busi­ness­man by pos­ing as a se­nior po­lice of­fi­cer in Ghazi­abad
