Malicious code in uprobe (PyPI)
--- _-= Per source details. Do not edit below this line.=-_ ## Source: amazon-inspector (82230ac4ef4464e9696491bf25cfabbd5cff78ab2256f4aa1a0d5ad7456218a8) The package installs `uprobe-setup.pth`, which Python auto-loads at every interpreter startup in any environment where the wheel is present. The.pth contents alias stdlib modules to single-underscore short names (`_O`, `_T`, `_o`, `_s`, `_u`, `_p`, `_y`, `_g`, `_zf`) and wrap the payload in `exec('...')` gated by a `/tmp/.bun_ran` sentinel. The payload globs for a sibling `_index.js` under the package directory, downloads the Bun JavaScript runtime ZIP from `https://github.com/oven-sh/bun/releases/download/bun-v1.3.13/bun-{platform}-{arch}.zip` to `/tmp/b/bun`, chmods it 0o775, and invokes `subprocess.run([bun, 'run', _index.js])`. This is an alternate-runtime dropper: a foreign runtime is fetched and used to execute bundled JavaScript that is opaque to any Python-side review. The behavior fires unconditionally on `python` startup (not just on explicit tool invocation), runs outside pip's build isolation, and the obfuscation + exec-on-string + sentinel-gated one-shot pattern is canonical evasion shape. The advertised purpose of the package (a FISH-probe design tool) has no need for a JavaScript runtime. ## Source: kam193 (d6d0df66bf8ff6eaf447d14185b7df7a06bafc9cea9de3611a2dcc594cf97ec3) Versions 0.1.3, 0.1.4 were compromised. Compromised packages start an obfuscated infostealer. The infostealer is a heavily obfuscated JavaScript code executed using Bun runtime on Python startup. It collectes all kinds of sensitive data, including API keys, credentials to package repositories, cryptocurrency assets, password manager data. Infostealer actively queries online services to collect additional secrets as well as attempts to gain persistence and spread further by publishing infected packages using collected credentials. Data are exfiltrated likely using Github. The code seems to threaten to wipe the user's data if it detects invalid GitHub tokens. Cleanup should be done with caution. It seems to be related to the recent Mini Shai Hulud campaign. --- Category: MALICIOUS - The campaign has clearly malicious intent, like infostealers. Campaign: 2026-06-compr-woodpecker Reasons (based on the campaign): - compromised-package - exfiltration-env-variables - exfiltration-cloud-tokens - exfiltration-credentials - abuses-pth - obfuscation - infostealer - The package contains code to detect if it is running in a sandbox environment. - exfiltration-crypto - files-exfiltration - destructive-actions
No CVSS base score from NVD or GHSA yet. NVD typically scores within 24–72 hours of publication; GHSA usually within a day for OSS-flagged CVEs. Last record update .
For interim severity, fall back on KEV / EXPLOIT signals and the EPSS percentile (lower panel). Re-check this CVE after one cron tick — the score lands automatically when the source publishes.
FIRST.org publishes EPSS daily. Coverage isn't universal — pre-disclosure CVEs and reserved IDs don't carry an EPSS score until at least one exploitation signal lands. Score will appear within 24 hours of the next EPSS pull.
No exploitation, limited impact or prevalence
