Robocall ‘hijacking’ is on the rise, report warns

Robocallers are alive and kicking as they continually change ways, a brand new report says.

Individuals are nonetheless flooded by 200 million undesirable robocalls a day, in keeping with a report from Transaction Community Companies (TNS), a telecommunications providers firm.

Excessive-risk calls grew at 28 p.c from the third quarter of final 12 months to the second quarter of this 12 months, whereas nuisance calls jumped 38 p.c, TNS mentioned.


A high-risk name is usually one thing like id theft, which might trigger “extreme emotional misery,” TNS mentioned. Nuisance calls are usually not malicious however the results of careless, unintentional calling patterns. 

Carriers have turn into extra aggressive in blocking robocalls, in accordance a June 2019 Declaratory Ruling by the FCC. That’s “why subscribers might even see high-risk calls not rising as quick as nuisance calls,” TNS mentioned.

Additionally on the rise: robocall hijacking. One in 1,700 cellular numbers is being hijacked by robocall spoofers each month, greater than double final 12 months’s determine of 1 in 4,000 cellular numbers. This has brought about some individuals to disconnect their cellphone quantity, in keeping with TNS.

Sometimes, unhealthy actors spoof reliable toll-free numbers of high-profile tech firms and declare there’s something unsuitable with the sufferer’s account in an effort to acquire private info, he mentioned.


Toll-free numbers accounted for 25 p.c of high-risk calls within the first half of 2019, up from 17 p.c final 12 months, Tyrrell mentioned.

The same development is high-volume “snowshoe” spamming. Right here, a nasty actor will spoof a neighborhood quantity however will unfold these calls in excessive quantity over a number of numbers every day over a number of days utilizing misleading name practices which might be tough for robocall-blocking apps to detect.

“By the point [the app] determines the quantity to be from a nasty actor, the unhealthy actor has moved on from that quantity, TNS mentioned.


Main U.S. carriers are solely a small a part of the issue, TNS mentioned. Whereas 70 p.c of all calls, constructive and unfavourable, come from tier-one U.S. suppliers, solely 12 p.c of the calls from these carriers’ numbers are thought-about high-risk.
