86.2 Million Phone Scam Calls Delivered Each Month In the US

An anonymous reader writes with a report from Help Net Security which assigns some numbers to the lucrative fraud-by-phone business in the U.S. -- and it's not just the most naive who are vulnerable. "Phone fraud continues to threaten enterprises across industries and borders, with the leading financial institutions' call centers exposed to more than $9 million to potential fraud each year," says the article. "Pindrop analyzed several million calls for threats, and found a 30 percent rise in enterprise attacks and more than 86.2 million attacks per month on U.S. consumers. Credit card issuers receive the highest rate of fraud attempts, with one in every 900 calls being fraudulent."

What's been your experience with fraudulent robocalls? I've been getting them on a near-daily basis -- fake credit card alerts, "computer support" malware-install attempts, and more -- for a few years now, which makes whitelisting seem attractive. ("Bridget from account services" has been robo-calling a lot lately, and each time she says it is my final notice.) My biggest worry is that the people behind these scams, like spammers, will hire copywriters who can fool many more people.

    all toll-free go to an auto-attendant that is a robot-check.
    all "number unavailable" goes to another robot-check.
    obvious fake phone numbers go to the blacklist auto-attendant, an infinite loop, basically.
    known phone spammers go to the blacklist auto-attendant
    it's easy to add a number to the blacklist.

    On a typical day, 3 to 5 calls get gobbled up by asterisk. The phone rings once, the caller id is read, and the caller is sent away. It is *wonderful*.

    She who must be complied with does not want to go to what I consider the ultimate solution, the white list for immediate pass-through, and a robot check for all other calls.

    The spam callers that do get through are verbally abused before their number is added to the blacklist.

    Want to know who to blame for this crap? The corporations who pushed to be able to spoof their caller ID -- so they could call us from foreign call centers.

    I'm sure the technology exists or could be added to the phone system to basically say "if your caller ID is faked, we're not even accepting this".

    I've started seeing the fake caller ID get to the point that it has the same area code and exchange as my own number ... once I apparently even called myself.

    Essentially incoming calls have to all be treated as fraudulent, because they've been just created by a computer to conceal where it's actually coming from.

    It has gotten to the point where if I don't know the number by sight, and then the persons voice, I pretty much tell all callers to piss off and go away.

    Sometimes the legitimate callers get all butt hurt, but I simply don't care ... because 95% or more of incoming calls on my phone are 100% fraudulent, and involve some clown in an overseas call center trying to scam me.

    And the problem is that it is probably the same exact call center that legitimate companies use, or one which has decided scamming is more lucrative than tech support.

    But between the Microsoft Service Provider, the people who want to clean my ducts, the automated call telling me I've won a free cruise, the automated call telling me I need to respond about lowering my credit card rate ... incoming callers find a hostile person who assumes they're lying to me.

    Sometimes I yell at them, sometimes I mess with them, but most of the time I just hang up immediately or leave it to the answering machine.

      I don't know about the US, but it's similarly a sham in the UK.

      I have two phone lines, the second always got spam calls, it was obviously a line some idiot had plastered everywhere and then given up only for BT to re-assign it to me, luckily I only have that line for my secondary internet connection so there's no phone on it anymore anyway.

      But when I initially did have a phone, I asked BT how they intended to resolve the issue given that it was receiving junk calls through no fault of my own. The short answer is, they refused to unless I pay them money - fat chance given that it wasn't a problem I caused. The long answer is that there are actually two types of withheld number - there's a number withheld within the UK, which BT can see, but doesn't get passed to me, the owner of the line, there's a withheld number of foreign origin - they can tell where the call comes from, but not the original number. Both these types of blocked numbers can be differentiated at the customer's end point. I asked therefore, if they could simply block all calls from India, because I frankly have no interest in talking to anyone from there, and was told I could only block all international calls, or none at all, and as much as I'd like to prevent my mother in law from Canada ever calling, that wasn't an option because the other half would have something to say about that. Oh, and I'd have to pay them for the privilege, again, bearing in mind this was a problem of their making, not mine.

      I similarly asked whether any of the withheld number calls I listed as unsolicited were from the UK and was told that they were, I asked what the numbers were but was told for data protection reasons they couldn't give me them, this was troubling for two reasons. Firstly, companies aren't protected by the data protection act and these were commercial calls, and secondly companies have a legal obligation to make their contact number available now.

      But there was a common theme throughout the discussions - they couldn't do anything, unless I pay them more, whether a few pounds a month to block at their end, or about £130 for their fancy new BT phone that can magically block these things.

      So it seemed perfectly clear that at least here in the UK, BT has everything it needs to help solve the problem, it could tell you details of companies calling you using hidden numbers if it wanted, and it could detect and block calls from certain countries if it wanted. Similarly, it could use market-led approaches to the problem, it could charge penalty costs to route calls from problem countries. India would soon get it's criminal call centre industry in line, if it's legitimate call centre industry was put at commercial risk.

      But as it stands, it's just too easy for them to make money from making sure the problem remains a problem, they're making a fortune charging people for simple features that should be part of the already astoundingly high £17 a month line rental, and there's too much profit in charging for phones with built in filtering functionality such as whitelists.

      So yes, solutions are already either widely available, or technically or even commercially trivial to implement. What's missing is the will for telcos to solve the problem when they're allowed to share the profit for it. This is unfortunately I suspect something that will not change without legislation.

      Dude, you are clueless on multiple levels. First, "spoofing" caller ID is normal - the ability to tell the phone company (this is a *high* level overview) what your number is when making outbound calls when using a non-POTS line. Due to the way the phone network works this can't easily be changed. And companies have done this for decades, it's not something new. Big multi-line companies typically want outbound calls to come from a single switchboard number.

      I think there's two kinds of "spoofing" -- legitimate spoofing, where you own the DID number that you send out outbound trunks (eg, main phone number, etc) and bullshit spoofing, where at best you're obfuscating the source of your calls (eg, some hired call center that sends their client's DID info as caller ID) or worse, deliberately sending false or nonsense caller ID information to hide and obscure your call origin.

      Telecoms providers could filter client outbound trunks and drop calls with bogus calling party information, where bogus is defined as something like "you don't control that DID and have no written permission to use it". The FCC could require telecoms providers to do this very thing.

      I'm sure it would be messy and complicated to get setup, but so many calls are handled by the major carriers (ATT, Verizon, CenturyLink, etc) that you have a natural choke point that limits the ability of rogue providers to hand off calls.

  5. Verified CallerID would help by david.emery · · Score: 2

    I've advocated (including to my senator, Warner (D) of Virginia, a former telecom executive) that the FCC should require changes to make CallerID Verified. By this I mean that the Telco/switch has to verify the CallerID (e.g. using payment data?), and mark the CallerID information as either verified or suspect. This would not solve the problem, but would, I believe, help both consumers and Law Enforcement.

    As long as spammers can forge CallerID, we won't be able to depend on CallerID to screen calls, and DoNotCall registry violations will be much harder to enforce. "Brigitte from Credit Card Services" calls usually have a City/State CallerID value, rather than the name of an individual or organization. But I get some legitimate calls (e.g. my dog's oncologist) that also show up as City/State. (I know to answer calls from Vienna, VA - at least until the Spammers start forging local CallerID values...) My former employer removed its telephone number from the CallerID information, I know if I get a call from "732" (New Jersey area code) that it's most likely one of my former co-workers.

    But recently I've been getting Spam calls on my cell, usually (but not always) the CallerID says "unknown". Until this month, such calls were limited to the Land Line (and this is the single strongest argument for ditching the land line.)

Those logs are also required to be available for (allegedly) authorized law enforcement agencies and they're one reason why the old movie trope of "keep them on the line while we trace this call" is bogus. If the connection was made at all, no matter how briefly, there's a record constructed by automated equipment.

    Naturally, if the true origin of the call is coming in from some other source, the phone company can only trust whatever ID came in from that source, but they definitely know where the call itself came from and that means that law enforcement can then track back until such point where they cannot gain any sort of co-operation.
