Evil-WinRM is a WinRM shell for hacking/pentesting that connects to Windows servers via WinRM, supporting pass-the-hash, KerberosKerberosA network authentication protocol that uses tickets issued by a trusted service. Users and services can prove their identities without sending a password to each application., in-memory payload execution, and AMSI bypass.

Summary
evil-winrm is an open-source command-line shell, free to use, that connects to Windows machines over WinRM for post-exploitation work once valid credentials are in hand. It runs as a Ruby-based CLI on Linux or Windows clients and is aimed at red teamers and penetration testers rather than system administrators, though the README notes administrators could use it too. Its purpose is to replace a bare WinRM connection with something built for offensive use: it loads PowerShell scripts, DLLs, and C# assemblies into memory, supports pass-the-hash and Kerberos authentication including ccache and kirbi files, and includes a dynamic AMSI bypass. First committed in 2019, it remains actively maintained, with 24 contributors and a release just 30 days ago.

How evil-winrm helps
Which machines in this environment will let me in with just a hash or a ticket, no plaintext password needed?
opens an interactive PowerShell-style session over WinRM using pass-the-hash or Kerberos authentication, including ccache and kirbi ticket files, so credential material captured earlier is what gets you in
Can I run a script or tool on this host without it ever touching disk where an AV product might catch it?
loads PowerShell scripts, DLL files and C# assemblies straight into memory, with a dynamic AMSI bypass to keep those loads from being flagged
What services are running on a machine I've only got low-privilege access to?
lists the services on the remote machine over the same WinRM session without requiring elevated rights
Did I leave any trace of my commands or session on this box after I disconnect?
keeps command history stored locally per user and host rather than on the target, and clears the screen on request, but the session itself still runs as an interactive shell on the remote machine

Nine scores for evil-winrm, each built from the releases, notes and API history this site tracks — and, on Researcher and Business, where it stands among every measured tool in its category and how that has moved.
Score cards are part of every paid plan.

Blank means never measured; nothing here is a filled-in zero.
Peer standings are included with Researcher and Business. See how this tool ranks against its competitors, using data we don't publish anywhere else.
See plans →Each score is 0–100 on a published rubric, derived from data this site already shows. A dimension we cannot measure says so — it is never scored 0 and never enters a rank.
How this is scored
- Shipping velocity — releases a month over the last 12 months, on a log scale where 16 a month scores 100. Needs 3 releases in the window.
- Documentation quality — the release-notes rubric published on the analytics page, unchanged.
- Breaking-change discipline — the share of releases carrying a breaking change (none scores 100, half or more scores 0). Only projects that label breaking changes are measured: a clean record cannot be told from an unlabelled one.
- Maintenance risk — quiet time measured against the tool's own release cadence (quiet longer than 90 days and three typical gaps scores 0), plus the number of active maintainers and whether contributors are growing, where known. Higher is lower risk.
- Innovation & surface — new capabilities in the feature ledger this year, API and MCP operations added, and the share of commits that are features: the mean of whichever we hold.
- Community health (open-source tools only) — each is a direction, not a size: contributors this year against last, the bus factor now against a year ago, and issues closed per issue opened, where steady scores 50, doubled 100 and halved 0; plus the median time to a maintainer's first reply (an hour scores about 100, a month or more 0). A commercial card has no repository and carries none of the four.
- Documented delivery (commercial tools) — when a vendor's documented new capabilities have slowed against its own baseline, that counts against the overall standing as heavily as two low dimensions. Steady delivery, or too little history to judge, leaves the standing alone; it is never a sixth score.
- Open-source tools are scored on repository signals; commercial tools on their published changelog. Ranks compare tools within one category and one profile and need at least five measured peers; the overall standing needs three ranked dimensions. Best-in-breed or consolidator is a shape, not a quality, and is never scored.
