Does ignoring robocalls make them stop? Researchers uncover 2 key findings

Greater than 80 % of robocalls come from faux numbers – and answering these calls or not has no impact on what number of extra you’ll get. These are two key findings of an 11-month study into unsolicited telephone calls that we carried out from February 2019 to January 2020.

To higher perceive how these undesirable callers function, we monitored each telephone name obtained to over 66,000 telephone strains in our phone safety lab, the Robocall Observatory at North Carolina State College. We obtained 1.48 million unsolicited telephone calls over the course of the examine. A few of these calls we answered, whereas others we let ring. Opposite to popular wisdom, we discovered that answering calls makes no distinction within the variety of robocalls obtained by a telephone quantity. The weekly quantity of robocalls remained fixed all through the examine.

As a part of our examine, we additionally developed the primary methodology to determine robocalling campaigns accountable for a lot of these annoying, illegal and fraudulent robocalls. The primary kinds of robocalling campaigns had been about pupil loans, medical insurance, Google enterprise listings, common monetary fraud, and a long-running Social Security scam.

Utilizing these strategies, we realized that greater than 80 % of calls from a median robocalling marketing campaign use faux or short-lived telephone numbers to position their undesirable calls. Utilizing these telephone numbers, perpetrators deceive their victims and make it rather more tough to determine and prosecute illegal robocallers.

We additionally noticed that some fraudulent robocalling operations impersonated authorities companies for a lot of months with out detection. They used messages in English and Mandarin and threatened the victims with dire penalties. These messages goal weak populations, together with immigrants and seniors.

Why it issues

Suppliers can determine the true supply of a name utilizing a time-consuming, guide course of referred to as traceback. As we speak, there are too many robocalls for traceback to be a sensible answer for each name. Our robocalling marketing campaign identification approach isn’t just a robust analysis device. It will also be utilized by service suppliers to determine large-scale robocalling operations.

Utilizing our strategies, suppliers want to research solely a small variety of requires every robocalling marketing campaign. By focusing on the supply of abusive robocalls, service suppliers can block or shut down these operations and shield their subscribers from scams and illegal telemarketing.

What nonetheless isn’t identified

Suppliers are deploying a brand new know-how referred to as STIR/SHAKEN, which can forestall robocallers from spoofing their telephone numbers. When deployed, it should simplify traceback for calls, nevertheless it received’t work for suppliers who use older know-how. Robocallers additionally shortly adapt to new conditions, so they might discover a means round STIR/SHAKEN.

Nobody is aware of how robocallers work together with their victims and the way usually they modify their methods. For instance, a rising variety of robocalls and scammers at the moment are using COVID-19 as a premise to defraud individuals.

What’s subsequent

Over the approaching years, we are going to proceed our analysis on robocalls. We are going to examine whether or not STIR/SHAKEN reduces robocalls. We’re additionally creating strategies to raised determine, perceive, and assist suppliers and regulation enforcement goal robocalling operations.
