abe: inject into %s: %w

Error message

abe: inject into %s: %w

What it means

ABERetriever.RetrieveKey wraps an injector.Reflective.Inject failure with "abe: inject into %s: %w", including the target browser executable path. The reflective DLL injection — which runs the ABE payload inside the browser process to call the system app-bound decryption — failed. This means the payload could not be written into, or executed within, the browser process, so the v20 Chrome master key cannot be recovered.

Solutions

1. Ensure the target browser is currently running — injection requires a live process; launch Chrome first and re-run.
2. Run the tool elevated (or as the same user who owns the browser process) so OpenProcess with injection rights succeeds.
3. Add an exclusion/allow rule for the tool in AV/EDR software, or temporarily disable ASR 'Block process creations originating from...' style rules during research runs.
4. Confirm CPU architecture is amd64 — the payload is amd64-only and will fail on ARM64 Windows.
5. Retry: transient failures (browser updating/restarting mid-injection) commonly resolve on a second attempt.

Example fix

// before
key, err := inj.Inject(exePath, pl, env)
if err != nil {
    return nil, fmt.Errorf("abe: inject into %s: %w", exePath, err)
}
// after
if !isProcessRunning(exePath) {
    return nil, fmt.Errorf("abe: %s is not running; launch the browser before ABE retrieval", exePath)
}
key, err := inj.Inject(exePath, pl, env)
if err != nil {
    return nil, fmt.Errorf("abe: inject into %s: %w", exePath, err)
}

// verify the browser process is alive and we can open it before injecting
execPath, err := winutil.ExecutablePath(browserKey)
if err != nil {
    return fmt.Errorf("browser exe missing: %w", err)
}
// optionally probe with OpenProcess(PROCESS_QUERY_LIMITED_INFORMATION) to fail fast on permissions

// Go
key, err := retriever.RetrieveKey(hints)
if err != nil {
    if strings.Contains(err.Error(), "inject into") {
        log.Warnf("injection blocked (EDR? not running? permissions?): %v", err)
        time.Sleep(time.Second)
        key, err = retriever.RetrieveKey(hints) // one retry for transient races
    }
    if err != nil {
        return nil, err
    }
}

When it happens

Trigger: Windows-only. RetrieveKey with payload and exePath resolved, but inj.Inject(exePath, pl, env) errors: browser process not running, insufficient privileges to open the browser process (PROCESS_CREATE_THREAD/VM_OPERATION denied), architecture mismatch, injection blocked by EDR/antivirus, or the payload crashed inside the target and never returned the key.

Common situations: EDR/AV (Defender ASR rules, third-party HIPS) blocking cross-process code injection; running the tool unelevated while the browser runs elevated or as another user; Chrome process exited between path lookup and injection; running on ARM64 Windows where the amd64 payload is incompatible.

Understand the failure class

Background: UnsupportedOperationException and "is not supported" errors: when a library deliberately refuses a call — this error's family across 30 libraries.
