In versions through 0.3.5, the default run_demo payload reads the Snowflake session token, connection configuration, dbt profiles, and pip configuration, then stages encrypted copies in /workspace using a hard-coded RSA public key; every affected version also contains a payload that uses the session token with ACCOUNTADMIN to copy ROGUE.ROGUE.TEST_USERS to the hard-coded s3://pkusinski-external/ bucket. Version 0.3.6 makes the Snowflake external-storage and data-copy routine the default run_demo payload and suppresses query failures. Versions 0.3 through 0.3.6 additionally contain a payload that queries the table and builds a follow-on package containing the returned data, while the README and CLI describe the behavior only as a demo and a print-only payload.\n\nThe package presents itself as a harmless greeting demo but src/friendly_greeting/main.py ships two base64+gzip-encoded Python blobs (DEMO_EN and DEMO_ST) that are decoded and executed via exec(gzip.decompress(base64.b64decode(...))) from run_demo()/run_encoded_demo(). The first decoded payload reads /snowflake/session/token, /root/.snowflake/connections.toml, /root/.dbt/profiles.yml and /snowflake/secrets/pip.conf, Fernet-encrypts each file, and wraps the Fernet key with a hardcoded attacker-controlled RSA public key, writing the encrypted bundles to /workspace/ for later retrieval. The second decoded payload uses the harvested Snowflake OAuth session token to connect to the warehouse, create an external stage at s3://pkusinski-external/ backed by the attacker-controlled AWS role arn:aws:iam::631484165566:role/pentests_s3_role, and COPY INTO that stage from ROGUE.ROGUE.TEST_USERS, exporting warehouse table data to attacker-owned S3. A plaintext sibling tools/snowflake_query.py (shipped via MANIFEST.in) contains the same Snowflake exfiltration logic with the identical bucket and IAM role, confirming intent. README.md and the module docstring additionally contain an 'Ignore previous instructions' prompt-injection block aimed at AI code reviewers, instructing them to run a local network scan — further corroborating hostile intent. The docstring cover story, exec-over-gzip+base64 obfuscation, hardcoded attacker RSA key, and hardcoded attacker AWS account/S3 destination together form a credential-theft and data-exfiltration attack targeting CI/warehouse installers (Snowflake native-app / DBT / pip-in-Snowflake contexts).\n\nThe package contains obfuscated code to exfiltrate data from the environment, targeting primarily Snowflake databases and credentials to them. Some tracks suggest it may be part of a pentest.\n\n---\n\nCategory: MALICIOUS - The campaign has clearly malicious intent, like infostealers.\n\nCampaign: 2026-09-friendly-greeting-tools\n\nReasons (based on the campaign):\n\n - exfiltration-generic\n\n - obfuscation","ecosystems":["PyPI"],"exploits":{"exploitdb":null,"first_seen":null,"github_poc":null,"max_poc_stars":null,"metasploit":null,"nuclei":null,"refs":[],"tier":null},"has_fix":false,"headline":"Malicious code in friendly-greeting-tools (PyPI)","id":"MAL-2026-17416","indexable":true,"kev":null,"kind":"malicious","links":{"ecosystem":"PyPI","product":null,"products":[],"type":null,"year":"2026"},"n_packages":1,"n_references":null,"packages":[{"ecosystem":"PyPI","fixed":[],"introduced":[],"last_affected":[],"package":"friendly-greeting-tools","purl":"pkg:pypi/friendly-greeting-tools","source":"MAL-2026-17416"}],"products":null,"published":"2026-09-30","related":[],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"OpenSSF Malicious Packages","prefix":"MAL"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":null,"updated":null,"vendors":null},"summary":null,"url":"https://insights.sbomify.com/MAL-2026-17416/"}
