# Forcefield 1.2.1

Released on Sep 18, 2026

### Overview

Forcefield 1.2.1 strengthens protection against code injection, tampering, and driver vulnerabilities. It also improves installer feedback and ensures the service starts correctly after SYSTEM-context deployments.

### Changes

**FF-19**: Installer fails explicitly with an error message instead of failing silently on incompatible host architecture

**FF-22**: Resolves issue with SYSTEM-context deployments (e.g., Intune) so Forcefield service properly auto-starts on login after reboot

**FF-25**: Fixes denial-of-service / buffer overflow vulnerability in keeperforcefield.sys during Authenticode hash calculation

**FF-26**: Fixes vulnerability allowing bypass of Forcefield protections via thread manipulation

**FF-27**: Adds `keeperdb-desktop.exe` (KeeperDB) to the driver's list of protected processes

**FF-28**: Resolves bypass vulnerability involving DLL injection into trusted sihost.exe process

**FF-29**: Adds keeperforcefield.exe to driver protected process list for self-protection against tampering

**FF-30**: Updates handle stripping to remove `PROCESS_VM_WRITE` and `PROCESS_VM_OPERATION` to prevent code injection

**FF-31**: Corrects driver process name from keeper-gateway-service.exe to keeper-gateway.exe

**VM-1367**: Bugcrowd vulnerability report for keeperforcefield.sys kernel pool buffer overflow

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://newdocs.keeper.io/en/release-notes/desktop/forcefield/forcefield-1.2.1.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
