analyzing-slack-space-and-file-system-artifacts
Examine NTFS slack space, MFT entries, the USN Change Journal, and Alternate Data Streams (ADS) to recover hidden or residual data, reconstruct deleted-file metadata, and reconstruct available file-system change activity from USN records. Use during deep forensic analysis of an NTFS image when standard file recovery is insufficient, such as hunting for data hidden in ADS.

E005: Suspicious download URL detected in skill instructions.
What this means
Detected a suspicious URL in the skill instructions that could lead the agent to download and execute malicious scripts or binaries. This includes links to executables from untrusted sources, typosquatting of official packages, URL shorteners that obscure the destination, and personal file hosting services.
Why it was flagged
These are high-risk because they are direct .exe download links hosted on non-official/suspicious domains (malicious-site.com and its CDN), a common malware distribution pattern referenced in the skill's Zone.Identifier entries.
Low
Low-risk findings.
1 low severity finding. Worth noting, but not necessarily harmful.
W011: Third-party content exposure detected (indirect prompt injection risk).
What this means
The skill exposes the agent to untrusted, user-generated content from public third-party sources, creating a risk of indirect prompt injection. This includes browsing arbitrary URLs, reading social media posts or forum comments, and analyzing content from unknown websites.
Why it was flagged
The workflow ingests outsider-authored free text at runtime by extracting and parsing an attacker-provided forensic disk image file’s contents (e.g., slack strings/keywords and USN journal decoded filenames), which are arbitrary bytes/strings originating from that outsider-authored data.
