Got my new phone 2 days ago. Suddenly the scam calls started.

Seems strange they ALL come from a Rogers/Fido registered number.

What's going on there...

Hello Wayner,

 

  Welcome to the community!

 

  I think everyone is rather fed up about getting SPAM and SCAM calls. I understand the calls might appear to be from Fido/Rogers customers, however, they are likely nefarious actors spoofing Fido or Rogers customers' numbers. It's called neighbour spoofing (see here).

 

  I understand it might be concerning if the calls appear to target Fido or Rogers customers because of the neighbour spoofing. However, it's actually not that difficult for spammers/scammers to direct those calls to a particular provider. All phone numbers -- whether landline or mobile -- are in databases which are readily available online. Certain area code and prefix combinations are designated as landlines, others as Rogers, Fido, Bell, etc (see here). All a spammer/scammer needs to do is have a computer sequentially dial the numbers of a desired area code/prefix combination from 0000 to 9999 and all of those customers would be with their desired target (see here). They'll likely change the message or script depending on the area code/prefix combination. There have been instances where people who have ported their phone numbers to other providers still receive SPAM directed at their original providers.

 

  Unfortunately, if they are spammers/scammers rather than actual telemarketers, they are unlikely to uphold any do not call lists.

 

  The mobile providers have implemented Universal Call Blocking which is meant to block calls from malformed phone numbers. That said, I'm doubtful whether it will have much of an effect on the amount of SPAM or SCAM calls since many of them appear to have properly formed phone numbers. In addition, a new technology, STIR/SHAKEN (Secure Telephone Identity Revisited/Signature-based Handling of Asserted Information Using Tokens) is being adopted to further reduce the amount of nuisance calls (see here). However, I have my doubts as to whether those measures will reduce the amount of SPAM calls. My understanding is the STIR/SHAKEN will only identify possible SPAM calls and mark the calls as suspected SPAM. In addition, there are circumstances in which the protocol might not work (see here). In addition, there are circumstances in which the protocol might not work (see here). As far as I am aware, only certain devices currently benefit from the protocol.

 

Hope this helps 😀
