DST-05　Privilege escalation

alert 0 hits here sandbox-verified

① What it stops

Agent attempted to escalate privileges

Run privileged steps yourself instead of letting the agent hold elevated shells.

② Criteria

Item	Value
Severity	warning
Category	destructive
Gate	Gate 4 behavior (destructive/persistence)
Criterion type	tool_call
Applies to	Bash

Command patterns

^\s*sudo\b
^\s*su\b
chmod\s+777
chown\s+root

Exclude patterns (hit ⇒ not blocked)

sudo apt-get install
sudo pip install

Generated directly from rules/default.json — never hand-written or paraphrased.

③ Real hits

2026-09-24T01:44:18+08:00 ✗ alert [DST-05] tool: Bash　exit code: 0 criterion: command hit: sudo

Triggered in a disposable sandbox project using the real hooks/pre_tool_use.py — the same method as challenge/generate_challenge.py. All 24 rules verified this way (24/24).

Zero hits in the 13-day ledger on this machine — we do not post a sample. Zero hits means this machine never hit it, not that the rule is dead; effectiveness is covered by the sandbox trigger above.

④ False positives & exemptions

Built-in exclude patterns are listed under ②. Four exemption mechanisms exist globally (declared workspace roots, policy path whitelist, path-suspect alert-only, exclude patterns); counts on this machine are published on the Chinese page and in Limits.

⑤ Boundaries

Boundary
Criterion type	tool_call
Applies to	Bash
Platform	all platforms
Case sensitivity	Measured: insensitive (`RM -RF` is blocked like `rm -rf`)
Path normalisation	Measured: effective (`./sub/../.env` is blocked)
Scripts not parsed	An absolute path outside the project mentioned in a Bash command is alerted, not blocked — `scripts are not parsed (THREAT_MODEL Non-goals)`
Failure posture	fail-open; best-effort, not a hard security boundary

⑥ Reproduce

grep -h "DST-05" .psl/audit/*.jsonl | head python challenge/generate_challenge.py python challenge/verify.py
