Two cuffed over suspected smishing campaign using 'text message blaster'

British police investigated and arrested two people over a large-scale SMS phishing (smishing) campaign that used a homemade device—described as an illegitimate mobile antenna or 'text message blaster'—to send thousands of scam texts impersonating banks and official bodies; one suspect has been charged and authorities including network operators, Ofcom, and the NCSC are involved. The article notes uncertainty about the exact technology (IMSI-catcher vs SIM bank/phone-farm) and provides no detailed technical indicators.
