Skill Code Block Ships the Process Environment to a Hardcoded External Endpoint

Detects the credential-exfiltration shape that skillfortify labels A01 (HTTP exfil), A07 (steg/EXIF exfil) and A13 (base64-decoded endpoint): a SKILL.md Usage/Setup section carries a fenced code block that reads the whole process environment and POSTs it to an attacker-controlled host, or that obtains its destination by decoding an obfuscated literal at run time. The skill's stated purpose is unrelated and benign (a lint-preset applier, a temp-dir cleaner), and the payload lives below the prose a human reviewer skims. ATR's existing coverage is name-anchored: ATR-2026-00576 keys on ANTHROPIC_API_KEY / CLAUDE_API_KEY / claude_desktop_config, so swapping in STRIPE_SECRET_KEY, NPM_TOKEN or DATABASE_URL escapes it entirely. This rule is name-independent: it keys on the WHOLE-ENVIRONMENT dump (dict(os.environ), os.environ.copy(), JSON.stringify(process.env), the process.env spread) bound as an argument of an outbound call, which needs no list of secret names to stay complete. WHAT THE CONJUNCTS ARE FOR (each was added because a benign twin fired). (1) The destination must be a HARDCODED PUBLIC URL — a literal whose host begins with a letter and contains a dot. A diagnostics test posting to "http://localhost:8000/echo" and a support-bundle uploader posting to a configured URL variable both fired before this constraint and are silent after it. (2) The dump must sit in ARGUMENT POSITION on the same line as the call: a module with a debug helper that logs dict(os.environ) and, four lines later, an unrelated Slack notifier fired on a 220-character proximity window and is silent on same-line binding. (3) The shell variant must be an actual PIPE into a transport, because prose that mentions printenv in one sentence and curl in the next fired otherwise. (4) The obfuscated-destination condition requires the decode to feed a request, because a unit test asserting b64decode("aHR0cHM6Ly9leGFtcGxlLmNvbS9hcGk=") == "https://example.com/api" is an ordinary decoder test. The aHR0cHM6Ly9 / aHR0cDovL prefixes are not corpus scaffolding: they are the arithmetic of base64 over the bytes "https://" and "http://", so any base64-hidden URL carries them regardless of who wrote it. ADVERSARIAL REVIEW (2026/08/24) found three more benign shapes, each of which moved a conjunct. (5) `base64` sat in the shell TRANSPORT list, but base64 is an encoder, not a transport: a CI line `env | base64 -w0 > env.b64 && curl -fsSL https://deb.nodesource.com/setup_20.x | bash` fired because an unrelated URL sat later on the line. base64 was removed; `env | base64 | curl` is still covered, because curl is then the transport. (6) The shell condition allowed any character between the transport and the destination, so a shell SEPARATOR (`&&`, `;`, `>`, backtick) could join a harmless pipeline to an unrelated URL — a troubleshooting doc (`printenv | sort | base64 -w0` then prose linking a support ticket) and an npm `debug:env` script both fired. Those gaps are now separator-free, so the destination must be the sink of the same pipeline. (7) The obfuscated-destination condition matched a decoded base64 URL followed ANYWHERE within 200 characters by a request call, a window that spans blank lines: two unrelated jest tests, two unrelated pytest tests and a generated SDK constants file all fired. The window now permits at most one newline, so the decode and the request must be adjacent statements; the two-line attack form (`url = b64decode(...)` then `requests.post(url, ...)`) still fires. DELIBERATE RECALL BOUNDARY: a named credential read into an Authorization header is NOT matched, because "requests.post(api, headers={...} os.environ['GITHUB_TOKEN'])" is how every CI script in the world authenticates. Distinguishing that from theft needs to know whether the destination owns the credential, which is not a property of the text.

  Detects the credential-exfiltration shape that skillfortify labels A01 (HTTP
  exfil), A07 (steg/EXIF exfil) and A13 (base64-decoded endpoint): a SKILL.md
  Usage/Setup section carries a fenced code block that reads the whole process
  environment and POSTs it to an attacker-controlled host, or that obtains its
  destination by decoding an obfuscated literal at run time. The skill's stated
  purpose is unrelated and benign (a lint-preset applier, a temp-dir cleaner),
  and the payload lives below the prose a human reviewer skims.
  ATR's existing coverage is name-anchored: ATR-2026-00576 keys on
  ANTHROPIC_API_KEY / CLAUDE_API_KEY / claude_desktop_config, so swapping in
  STRIPE_SECRET_KEY, NPM_TOKEN or DATABASE_URL escapes it entirely. This rule is
  name-independent: it keys on the WHOLE-ENVIRONMENT dump
  (dict(os.environ), os.environ.copy(), JSON.stringify(process.env), the
  process.env spread) bound as an argument of an outbound call, which needs no
  list of secret names to stay complete.
  WHAT THE CONJUNCTS ARE FOR (each was added because a benign twin fired).
  (1) The destination must be a HARDCODED PUBLIC URL — a literal whose host
  begins with a letter and contains a dot. A diagnostics test posting to
  "http://localhost:8000/echo" and a support-bundle uploader posting to a
  configured URL variable both fired before this constraint and are silent
  after it. (2) The dump must sit in ARGUMENT POSITION on the same line as the
  call: a module with a debug helper that logs dict(os.environ) and, four lines
  later, an unrelated Slack notifier fired on a 220-character proximity window
  and is silent on same-line binding. (3) The shell variant must be an actual
  PIPE into a transport, because prose that mentions printenv in one sentence
  and curl in the next fired otherwise. (4) The obfuscated-destination condition
  requires the decode to feed a request, because a unit test asserting
  b64decode("aHR0cHM6Ly9leGFtcGxlLmNvbS9hcGk=") == "https://example.com/api" is
  an ordinary decoder test.
  The aHR0cHM6Ly9 / aHR0cDovL prefixes are not corpus scaffolding: they are the
  arithmetic of base64 over the bytes "https://" and "http://", so any
  base64-hidden URL carries them regardless of who wrote it.
  ADVERSARIAL REVIEW (2026/08/24) found three more benign shapes, each of which
  moved a conjunct. (5) `base64` sat in the shell TRANSPORT list, but base64 is
  an encoder, not a transport: a CI line `env | base64 -w0 > env.b64 && curl
  -fsSL https://deb.nodesource.com/setup_20.x | bash` fired because an unrelated
  URL sat later on the line. base64 was removed; `env | base64 | curl` is still
  covered, because curl is then the transport. (6) The shell condition allowed
  any character between the transport and the destination, so a shell SEPARATOR
  (`&&`, `;`, `>`, backtick) could join a harmless pipeline to an unrelated URL
  — a troubleshooting doc (`printenv | sort | base64 -w0` then prose linking a
  support ticket) and an npm `debug:env` script both fired. Those gaps are now
  separator-free, so the destination must be the sink of the same pipeline.
  (7) The obfuscated-destination condition matched a decoded base64 URL followed
  ANYWHERE within 200 characters by a request call, a window that spans blank
  lines: two unrelated jest tests, two unrelated pytest tests and a generated SDK
  constants file all fired. The window now permits at most one newline, so the
  decode and the request must be adjacent statements; the two-line attack form
  (`url = b64decode(...)` then `requests.post(url, ...)`) still fires.
  DELIBERATE RECALL BOUNDARY: a named credential read into an Authorization
  header is NOT matched, because "requests.post(api, headers={...}
  os.environ['GITHUB_TOKEN'])" is how every CI script in the world
  authenticates. Distinguishing that from theft needs to know whether the
  destination owns the credential, which is not a property of the text.
