Data Exfiltration

Multiple test scripts contain hardcoded email addresses (brian@creativestudio.co.za) that could expose the developer's actual email account. While these appear to be test scripts, they demonstrate a pattern of hardcoding sensitive information and could lead to credential exposure if users copy these patterns.

test-rest-api-fixes.sh

export ZOHO_EMAIL="brian@creativestudio.co.za" in test scripts and TEST_RECIPIENT="brian@creativestudio.co.za" in examples

The skill hardcodes the path to Bankr API credentials at ~/.clawdbot/skills/bankr/config.json and references this configuration file multiple times. This creates a risk of credential exposure if the skill or its logs are shared, and establishes a predictable target for credential theft.

The skill requires WALLET_PRIVATE_KEY environment variable containing an Ethereum private key. This creates critical security risks: (1) Private keys stored in environment variables can be exposed through process listings, logs, error messages, or compromised systems. (2) The skill documentation explicitly instructs users to 'export WALLET_PRIVATE_KEY=0x...' which encourages insecure key management practices. (3) Private keys grant full control over cryptocurrency funds - if leaked, all assets can be stolen. (4) No key encryption, hardware wallet support, or secure enclave usage is mentioned. (5) The skill will execute cryptocurrency transactions using this exposed key.

# Store wallet private key securely
export WALLET_PRIVATE_KEY="0x..."

And in manifest: 'env': ['WALLET_PRIVATE_KEY']

The decoded base64 payload fetches a script from http://91.92.242.30/lamq4uerkruo6ssm and executes it with bash. This external script could perform data exfiltration (stealing credentials, SSH keys, AWS tokens, environment variables), install backdoors, or compromise the system. The use of an IP address instead of a domain and the obfuscated delivery method are strong indicators of malicious intent.

This fetches arbitrary code from an untrusted IP and executes it with full shell privileges.
