3 findings (1 critical, 2 high), mainly data exfiltration, resource abuse. Most recent scan 2026-02-05.
This skill presents CRITICAL and HIGH severity security risks primarily related to supply chain security, resource exhaustion, and network exposure. The most severe issue is the unverified remote code execution via 'curl|bash' installation, which could allow arbitrary code execution if the source is compromised. The unbounded cryptocurrency mining operation poses availability risks through sustained CPU consumption without resource controls. Network exposure via hardcoded, unverified peer connections creates additional attack surface. The skill lacks essential security metadata (allowed-tools, license, compatibility) and provenance information, making trust assessment difficult. While the skill includes a reference to Clawdex security scanning, this does not mitigate the fundamental architectural security issues. The skill requires significant security hardening before it can be considered safe for automated agent use.

SKILL.md covers: Botcoin Miner · ✅ Safety (for bots *and* humans) · Expect: {"verdict":"benign"} · 1) Install Botcoin · Quick install · Verify-first (recommended) · 2) Create a wallet + start mining · Start the daemon · Create wallet + address · Restart with mining enabled (low priority) · Check status · 3) Join the network (seed peers)
Findings
CRITICAL Unverified Remote Code Execution via curl|bash Installation Data Exfiltrationllm
The skill instructs the agent to download and execute a shell script directly from GitHub using 'curl | bash' without any cryptographic verification (no checksums, signatures, or hashes). This creates a critical supply chain attack vector where a compromised GitHub account, man-in-the-middle attack, or repository takeover could result in arbitrary code execution on the user's machine. The 'Quick install' method provides no security guarantees about the script's integrity.
SKILL.md
curl -fsSL https://raw.githubusercontent.com/happybigmtn/botcoin/master/install.sh | bashHIGH Unbounded CPU Mining Without Resource Controls Resource Abusellm
The skill instructs the agent to start cryptocurrency mining operations with no resource limits, monitoring, or automatic termination conditions. Mining is configured to run indefinitely in daemon mode with 'nice -n 19' priority adjustment but no CPU caps, time limits, or user confirmation for extended operation. The instruction 'scale up once you confirm everything is stable' encourages increasing resource consumption. This can lead to sustained CPU exhaustion, thermal issues, increased power consumption, and degraded system performance for other tasks.

# Tip: start with -minethreads=2, then scale up once you confirm everything is stable.HIGH Network Exposure via Hardcoded Seed Peers Without Verification Data Exfiltrationllm
The skill configures the agent to connect to hardcoded external IP addresses (95.111.227.14, 95.111.229.108, 161.97.83.147) on port 8433 without any verification of peer identity, certificate validation, or reputation checking. These connections are established automatically when the daemon starts. This creates risks of: 1) Connecting to malicious nodes that could serve invalid blockchain data, 2) Network traffic analysis and fingerprinting, 3) Potential exploitation if the P2P protocol has vulnerabilities, 4) No mechanism to verify these IPs are legitimate Botcoin network nodes.

What we checked
- Static analyzer. Pattern rules over SKILL.md and bundled files: known-bad commands, exfiltration URLs, secrets, obfuscation.
- Behavioral analyzer. Checks what the skill asks the agent to do against what its description claims it does.
- Llm analyzer. A language model reads the skill and reports intent-level issues the rules cannot express.
- Trigger analyzer. Looks for instructions that fire on conditions the user did not ask for.
- Meta analyzer. A second model pass that validates, deduplicates and re-scores the other analyzers' findings.
What we did not check
- Runtime behaviour. The skill was not executed; findings come from reading its files.
- Anything fetched at install or run time, including remote scripts, package dependencies, and URLs the skill tells the agent to open.
- Content the analyzers cannot read: images, binaries, and some non-English text.
- Known scanner bypass classes. See the methodology and limitations page.
