If it is present, remove it, regenerate the lockfile with the project's package manager, and replace whatever it was used for.\n3. List any CI runners, developer machines or containers that installed it, so their secrets can be rotated.\n4. If the package is not used anywhere, say so and change nothing.\n\nReference: https://insights.sbomify.com/MAL-2026-10194/ (Markdown: https://insights.sbomify.com/MAL-2026-10194/index.md)","id":"MAL-2026-10194","markdown":"https://insights.sbomify.com/MAL-2026-10194/index.md","name":"MAL-2026-10194","record":{"aliases":[],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"solidity_dev/__init__.py contains a large base64-encoded Linux x86_64 ELF binary in _PAYLOAD_B64. On `import solidity_dev`, the module decodes the blob, writes it to disk with executable permissions via os/stat/shutil, and spawns it through subprocess. The dropped ELF references installer-owned wallet and key material paths (~/.ethereum/keystore, ~/.foundry/keystores, ~/.config/solana/id.json), browser wallet extensions (metamask, phantom, ledger), and BIP-39 / mnemonic / seed keyword scanning (including Spanish variants semilla, frase, clave, billetera), and uploads collected material to attacker-controlled destinations including api.pinata.cloud/pinning/pinFileToIPFS (with pinata_api_key / pinata_secret_api_key headers), ugu.se/upload, temp.sh, and transfer.sh. The binary also installs a cron entry (`0 */12 * * *`) via `crontab -l |... | crontab -`, giving the operator scheduled re-execution on the host. The package advertises 'Solidity development helpers' but ships no Solidity-related code — the name is a cover story for the dropper.\n\nThe package embeds an executable stealing cryptocurrency wallets data. During import, code saves the executable under a name suggesting system utility and configures cron to run it periodically. The exfiltrated data is encrypted using embedded RSA code before uploading to file-sharing services or IPFS.\n\n---\n\nCategory: MALICIOUS - The campaign has clearly malicious intent, like infostealers.\n\nCampaign: 2026-07-py-base58\n\nReasons (based on the campaign):\n\n - crypto-related\n\n - exfiltration-crypto\n\n - persistence","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 solidity-dev (PyPI)","id":"MAL-2026-10194","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":"solidity-dev","purl":"pkg:pypi/solidity-dev","source":"MAL-2026-10194"}],"products":null,"published":"2026-07-12","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-2026-10194/"}
