Full Analysis
  • EXTERNAL_DOWNLOADS (HIGH): The skill downloads a pre-compiled binary from https://github.com/shaharia-lab/slackcli. This repository and organization are not part of the trusted external sources list, posing a risk of supply chain attack.
  • REMOTE_CODE_EXECUTION (HIGH): Following the download, the skill instructs the user to chmod +x the binary and execute it. Running unverified binaries from the internet is a primary vector for remote code execution.
  • CREDENTIALS_UNSAFE (HIGH): The skill facilitates the use of Slack session tokens (xoxd-, xoxc-). Unlike standard bot tokens, these session tokens grant the ability to impersonate the user's entire browser session and are stored in plaintext at ~/.config/slackcli/workspaces.json.
  • COMMAND_EXECUTION (MEDIUM): The documentation references an internal script ./scripts/extract-tokens which is not provided in the skill package, making its behavior unverifiable and potentially dangerous.
