| Titre | Pourquoi les fraudeurs nous blitz-ils avec des appels téléphoniques sur l'escroquerie? Why are fraudsters blitzing us with scam phone calls? |
| Texte | Chair of Cybersecurity at MTU, Dr. Donna O\'Shea, contributed to this article in the Irish Times This week I have received a half dozen mobile calls from a number purporting to be very similar to my own. The caller ID shows an 087 number – like my own – and the subsequent four digits were also identical to mine, while the last three varied each time. In the jargon, this is known as “neighbour spoofing”, when a false caller ID is sent, seeming to come from the same area you live in, or a familiar looking number, to make it more likely that you will answer. When I did answer a not very convincing automated recording from “the department of social protection department” said fraud had been associated with my Personal Public Service Number (PPSN). Many of you will have received similar calls, trying to get you to “press a key” and talk to someone who tries to get you to divulge your PPSN, name, and in some cases, bank details. A recent scam text pretending to be from an Irish bank tells users that access to their account has been restricted due to a hacking attempt and invites them to input details to unlock it. These are all part of the seemingly endless cycle of scams which seem to have exploded over the past couple of years – and got increasingly sophisticated. But why is this happening? Let\'s look, as we would with any business, at the economics of the phone frauds. 1. Falling barriers to entry One of the first things with any business is to look at the barriers to getting involved. Whether for a criminal or legal enterprise, the cost of establishment is vital and can have a key bearing on activity levels and competition. Up to recent years, undertaking phone scams that involved hiding numbers and making thousands of calls required a significant level of technical knowledge. Now, according to Dr Donna O\'Shea, head of the computer science department of Cork Institute of Technology (CIT), the requisite “exploit” kits are downloadable, can leverage VOIP (voice over internet protocol) technology to call from PCs and display fake numbers on the user\'s phone. “You don\'t have to be a technical person to do it any more,” she said. It is still hard to account for the massive volumes of calls now happening, according to O\'Shea, but there appears to be a sharp rise in call numbers as well as increased sophistication. Relatively easily spotted calls from far-away countries are now replaced by more sophisticated “spoofing” – using numbers displaying themselves as “ordinary” Irish numbers. Showing a number close to your one is just one variant of this. It has also led to people “returning” calls to these numbers, which in some cases are valid numbers with real – and puzzled – owners. “You rang me”. . . “No I didn\'t . . .” At the moment incoming calls cannot be easily verified as coming from valid numbers. As the industry deregulated, numbers became portable – an 087 number can operate as part of the 086 network and so on – making checking incoming numbers to see if they are valid difficult – though here and internationally this issue is being examined. Some US operators have introduced controls, but it is a constant battle to stay ahead of the scammers. Not only it is relatively easy, but generating tens of thousands of phone calls is cheap, with operators taking on a tiny – or zero – cost per call. And so the “success” rate required to make money is tiny. Business Insider calculated in the US that some 2.5 million calls could be bought from a provider for just $875 by illegal telemarketers or scammers. Even if one in every 10,000 yielded revenue averaging $7 on average, the initial investment would be doubled. And of course, phone calls are just one variant of the scammers\' art, which also includes text messages and emails, all in many ways increasingly sophisticated, particularly texts allegedly from financial institutions which click through to plausible fake sites inviting you to enter your details. 2. |
