Search — “STA1”

A sponsored BleepingComputer article by carrier Cape explains that SS7 and Diameter signaling abuse can locate phones, harvest IMSIs, redirect SMS (including 2FA codes) via false roaming claims, and impersonate subscribers without malware. It cites Citizen Lab's report on the STA1 actor rotating through eleven operator identities, and says Iranian-linked actors reportedly used outdated signaling to locate US personnel, but it details no specific confirmed compromise. Hunters have little concrete telemetry here; the content is general background and vendor marketing, so the main takeaway is awareness of signaling-layer exposure rather than a huntable intrusion.
