Detection & IOCs extracted from sources · hover to see the quote

• → CVE-2023-47610 is exploited via specially crafted binary SMS messages targeting the SUPL (User Plane Location) message handler on Telit Cinterion modems; monitor for unexpected or malformed binary SMS delivery to modem subscriber numbers ↗
• → The attack vector is the SMS messaging interface present on all affected modems; attacker only needs the subscriber number of the target modem — no authentication required, no physical access needed ↗
• → Operator-level binary SMS restrictions may be bypassed using a rogue/fake base station; detection should account for SMS originating from unexpected or spoofed base stations ↗
• → Successful exploitation grants deep OS-level access including RAM and flash memory manipulation on the modem — look for anomalous modem firmware behavior or unexpected memory writes post-SMS receipt ↗

• · Telit fixed some but not all of the disclosed vulnerabilities; patching status should be verified per device variant before assuming remediation ↗
• · Because the modems are embedded in third-party solutions, determining the full scope of impacted products across industrial, healthcare, and telecom sectors is non-trivial ↗
