Robocalling Scourge May Not Be Unstoppable After All (arstechnica.com) 236

Posted by msmash from the good-news dept.
Dan Goodin, writing for Ars Technica: New data shows that the majority of robot-enabled scam phone calls came from fewer than 40 call centers, a finding that offers hope the growing menace of robocalls can be stopped. The calls use computers and the Internet to dial thousands of phone numbers every minute and promote fraudulent schemes that promise to lower credit card interest rates, offer loans, and sell home security products, to name just a few of the scams. Over the past decade, robocall complaints have mushroomed, with the Federal Trade Commission often receiving hundreds of thousands of complaints each month. In 2013, the consumer watchdog agency awarded $50,000 to three groups who devised blocking systems that had the potential to help end the scourge. Three years later, however, the robocall problem seems as intractable as ever. On Thursday at the Black Hat security conference in Las Vegas, a researcher said that slightly more than half of more than 1 million robocalls tracked were sent by just 38 telephony infrastructures. The relatively small number of actors offers hope that the phenomenon can be rooted out, by either automatically blocking the call centers or finding ways for law enforcement groups to identify and prosecute the operators. "We know that the majority of robocalls only come from 38 different infrastructures," Aude Marzuoli, research scientist at a company called Pindrop Labs, told Ars. "It's not as if there are thousands of people out there doing this. If you can catch this small number of bad actors we can" stop the problem."

        It comes and goes in cycles. For awhile I was getting several a day from the same company shilling security systems. I finally got them to stop when I worked my way through their system getting farther and farther along each call until I managed to get a tech dispatched to an abandoned house not far from me. They stopped calling at that point.

        Depending on what I was doing at the time, I also enjoyed just letting them ramble on for awhile about their spiel, then give them an address in Canada or Australia or something. Really pissed them off.

        Nowadays they're almost all initially handled by an automated speech thing (albeit some are scary good) so it's harder to have fun with them.

        Here is my solution to deal with those shenanigans:

        * Every spam call you get, counterintuitively, ADD it to your Contacts under "Spam" BUT append a number.

        I still believe that regulators should require that, if a caller ID is to be presented, it should be traceable to an individual in the originating country (with the carrier responsible if it's not). A carrier should be able to warrant this to its interconnects - if it can't, that carrier's calls will all be presented with no caller ID.

        Customers can then reject calls without caller ID or from other countries if necessary.,Where caller ID is presented it is then traceable to a person, enabling existing state rules about such calls to be enforced.

        There is no good reason that I should be able to buy a VOIP account for a couple of dollars a month and spoof any caller ID.

      Our main "Home Phone Number" is a Google Voice line. One of the nice features they have is "spam filtering" for phone calls. If a person calls us and it's a robocall/scammer, we can block the number. Then, when they call again, they get a "this number has been disconnected" message. If enough people do this, calls from that number automatically are blocked. Often, Google Voice will alert us that we missed a call when our phones didn't ring. When we look into the number, it's invariably a scammer trying to get through.

Second, and more importantly, they're billing them for the calls. They're not sending out bills for thousands of calls to the spoofed IDs, but the real ones.

    The fact that the Internet was the "Wild West" is just because the Internet was ignored for a long time by the powers-that-be. My feeling is eventually you won't be able to connect to the Internet without an "approved" network connection device/router and that device will be monitored and encrypted traffic will be either disallowed or the router will do MITM to allow the monitoring to take place. This is all technologically possible today. Secure boot, locked down devices are just the start.
