VPNHIDECategory: Hooks and process integrity Status in RKNHardering 2.10.0: Active check Role in the verdict: Mixed
This page describes the actual implementation in RKNHardering 2.10.0. It distinguishes what can be done without root, what requires root, and where a mitigation only reduces one signal without hiding the VPN as a whole.
One ID combines two different sources. The legacy detectVpnFiles() checks /data/local/tmp/vpnhide, /data/data/com.vpnhide, /data/local/tmp/.vpnhide, and /data/data/com.vpn.hide; a matching path produces a high-confidence vpnhide finding. The deep detector also routes the results of two regression probes here: SIOCGIFINDEX/SIOCGIFNAME consistency and the SIOCGIFCONF tail. Oracle and tail-vpn results are high confidence, tail-oracle is medium, clean is informational, and unavailable is an error.
High confidence: an accessible legacy path, a stable interface index without a reverse name, or a VPN-like name in the tail of the SIOCGIFCONF buffer. Medium confidence: a plausible stale non-VPN tail. Clean and unavailable results are not detections.
The signal may indicate either a direct file artifact or incomplete interface filtering. The title alone does not identify the cause; inspect the detail and check ID.
How the line affects the report: The same ID is used for both informational summaries and suspicious lines. The outcome depends on the specific detail and checker branch.
The legacy path names do not match the current paths used by every VPNHide version. Regression oracles test specific implementation errors and may miss a different bypass.
This line must be evaluated together with neighboring signals. A clean result from a single API does not simultaneously cover Java Binder, libc, raw netlink/syscalls, procfs/sysfs, local sockets, and server-side indicators.
VPNHide is not normally installed without root, so the path should be absent. If an oracle signal appears without VPNHide, another filter or a ROM bug may be responsible; repeat the test against a clean baseline. To keep the VPN itself off a non-rooted phone, use an external gateway.
Install only from the official VPNHide release. Configure System Framework and exactly one native backend. After every update, run both regression check IDs: the absence of tun0 is insufficient if an index or stale tail remains. Do not combine kmod and KPM.
# Read-only check of accessible paths:
adb shell 'for p in /data/local/tmp/vpnhide /data/data/com.vpnhide /data/local/tmp/.vpnhide /data/data/com.vpn.hide; do [ -e "$p" ] && echo "$p"; done'
# Regression probe source:
rg -n 'vpnhide_ifindex|vpnhide_ifconf' app/src/main/cpp/vpnhide_regression_probe.cpp
In the UI, distinguish check IDs native.vpnhide.ifindex_consistency and native.vpnhide.ifconf_tail.
After any change, force-stop both RKNHardering and the VPN client, start them again, and repeat the full scan. Zygisk, Xposed, and kernel modules usually require a reboot. Compare not only this line but also neighboring signals: a partial hook often creates inconsistencies between APIs.
The probe itself runs with ordinary app permissions and does not request root. The ADB commands below are for orientation only: adb shell runs under a different UID and may see either more or less than the app process. The decisive test is to run the check again after a force-stop.
A kernel backend may cause a boot loop or panic; running multiple backends at once is especially dangerous. Deleting package data erases settings.
Before installation, save the boot/init_boot image and the module list. If a boot loop occurs, disable the most recent module through the manager’s safe mode or restore a known-good image.
Mixed. Verified from the legacy path list, the C++ regression probe, and the VpnNativeDetectorChecker confidence policy.
The status of a third-party solution does not automatically carry over to this device. A module developer’s claim is only the initial hypothesis; confirmation requires a reproducible RKNHardering result on the specific Android version, firmware, and kernel.
