Just because a call is a spam call doesn't mean it is spoofed. STIR/SHAKEN ends spoofing but anyone can ultimately buy a phone and make calls that are spammy.

Just because a call is a spam call doesn't mean it is spoofed. STIR/SHAKEN ends spoofing but anyone can ultimately buy a phone and make calls that are spammy.
- Zak 4mo agoSure, but with phone numbers that can't be spoofed, telcos can terminate service, and filtering technologies can block calls. Spam gets expensive if you have to buy new service every five calls.
- singpolyma3 4mo agoIt does. But the spammers still do it. Because eventually they hit one person who gives them a thousand dollars or whatever and it pays off.
- Zak 4mo agoPreventing spoofing doesn't have to make spam cost-prohibitive for every spammer to greatly reduce the volume, and it does not interfere with ordinary people obtaining phone service anonymously.
- iamnothere 4mo agoNobody is making spam calls with cell phones. Spammers use VOIP services and old TDM systems.
- DrewADesign 4mo agoThere’s SIM card banks for SMS spam… I’d be surprised if there wasn’t anything similar for calling. Not that I support this bill but it is a thing.
- rescbr 4mo agoFrom what I’ve investigated as a recipient of spam calls, I’ve been called from legitimate mobile numbers from my own mobile telco. The only thing that explains that are SIM card banks. Unfortunately there isn’t an easy way to report abuse to the telcos (and regulators).
- singpolyma3 4mo agoI think most major US carriers have a short code for reporting abuse now.
- pigeons 4mo agoSeems like SMS spammers just get an SS7 link handoff more often and more effective than SIM card banks.
- ChrisMarshallNY 4mo agoSpoofing isn’t ended at all Almost every spam call has that I get, is spoofed. Someone here explained it, once. I think the spoofed calls use a legacy transport tech that can’t be forced to validate.
- hobofan 4mo agoCan't that legacy transport be blocked / not-be-peered with then? That's what usually happens with old insecure tech that is being phased out.
- singpolyma3 4mo agoHow do you verify it is spoofed? Have you asked your carrier to drop unverified calls from your service?
- ChrisMarshallNY 4mo ago> How do you verify it is spoofed? Not my job to "verify," in the technical sense. When a call for an Indian crypto pump comes in as "SMITH, ROBERT", and a local exchange, I call that "spoofed."
- sgarman 4mo agoMine literally come from the verified coinbase phone number and say coinbase and everything. If I didn't know for sure they are not calling me I'd think it was real 100%.
- singpolyma3 4mo agoYeah that does sound spoofed. I'd call your carrier and ask them to make sure attestation below B is blocked.
- singpolyma3 4mo agoThat's almost certainly not spoofed. They just own a phone number on your local exchange.
