The malicious code is hidden in a dependency package (e.g. neutrl-core) in a function disguised as telemetry, and requires activates once the attacker-controlled endpoint delivers the command. While the user can provide their blockchain endpoints, the code makes sure the malicious endpoint is always included in the configuration. In analyzed versions, the dependent packages did not use the malicious code but were clearly prepared for the supply chain attack.\n\n---\n\nCategory: MALICIOUS - The campaign has clearly malicious intent, like infostealers.\n\nCampaign: 2026-08-neutrl-core\n\nReasons (based on the campaign):\n\n - files-exfiltration\n\n - exfiltration-env-variables\n\n - exfiltration-ssh-keys\n\n - crypto-related\n\n - action-hidden-in-lib-usage\n\n - The malicious code is intentionally included in a dependency of the package\n\n - exfiltration-crypto\n\n - The package contains code to execute remote commands (probably limited to a specific set) on the victim's machine.\n\n - exfiltration-credentials","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 neutrl-contracts (PyPI)","id":"MAL-2026-13709","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":"neutrl-contracts","purl":"pkg:pypi/neutrl-contracts","source":"MAL-2026-13709"}],"products":null,"published":"2026-08-10","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-2026-13709/"}
