Detection & IOCsextracted from sources · hover to see the quote
- →Vulnerability exists in rw_mfc_handle_read_op() within rw_mfc.cc — monitor for out-of-bounds write triggered via NFC packet processing on Android 10/11 ↗
- →No user interaction required and no additional privileges needed — exploit is fully remote via NFC; detection should focus on anomalous NFC traffic to Android 10/11 devices ↗
- →Affected platform versions are Android 10 and Android 11 only; scope detection/patching efforts to these versions ↗
- →Android bug tracker reference A-178725766 can be used to cross-reference patch status and affected builds ↗
- →Use Qualys QID 610331 (signature version SEM VULNSIGS-1.0.0.30) to detect unpatched devices; manufacturer-specific QIDs are 610329, 610330, 610332 ↗
- ·Exploit requires NFC to be enabled on the target device; attack surface is limited to NFC range (proximity). Disabling NFC on unpatched Android 10/11 devices reduces exposure. ↗
