Detection coverage update: Sigma rules for CVE-2025-53770 (“ToolShell”)

My team member @_swachchhanda_ contributed a set of Sigma rules that detect different stages of the recent SharePoint exploitation (CVE-2025-53770).

The rules are now public:
https://t.co/orTjB0ZDUh

They provide coverage for:
- Web shell deployment
- Post-exploitation behavior
- IIS log artefacts (initial exploitation)

These rules help detect both the initial access vector and follow-up activity using host and network data sources. They complement our YARA rules for the payloads themselves:

@Star_Knight12 No. 4gb is not good. I would 16gb is preferred as a min, but 8 could be passable based on the use cases.

@WebDesignMuseum Ahhh, flash. A decent ecma script implementation before the browsers really started taking javascript seriously.

@News3LV Ah yes, I'd like to report a scam, my monthly NV Energy bill keeps going up year over year even though we're using less energy.

@pnjaban I dont care who ya vote for, this'a car right here is a certified pre-owned, ya se! Fully stocked, locked and loaded!

@TrungTPhan Yeah, its sad. We had a great childhood. Kids today cannot be kids - we are constantly telling them how to play, what to do. I thinks this impacts thier independence and decision making skills.
