Security audit
Security checks for vulnerabilities and agentic risk
This skill is a coherent Volcengine TLS LogCollector deployment guide with expected but high-impact cloud, Kubernetes, and host installation steps.
Install only if you intend to let an agent help configure Volcengine TLS logging with cloud credentials, Kubernetes access, and possibly root access on target hosts. Verify official installer URLs and versions, prefer vendor-supported checksum/signature checks when available, avoid exposing AK/SK in command history, and review all dry-run output before any live write or install.
The natural-language strings in the skill metadata are entirely in Chinese and provide no indication that users may choose another language. This creates a locale/language policy concern because the skill appears to enforce a specific language without explicit user opt-in or a documented region-specific justification.
Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.
--input '{"topicId":"","delimiter":",;=|/","log":""}'
Do not copy delimiter examples into production without checking the actual query and tokenization requirements.

Commands invoke sudo or root privileges. Verify this elevated access is necessary and justified.
wget "https://logcollector-.tos-.volces.com/logcollector.tgz"
-O /tmp/logcollector.tgz
tar -xzf /tmp/logcollector.tgz -C /tmp
chmod 755 /tmp/logcollector/logcollector.sh
/tmp/logcollector/logcollector.sh --help
Commands invoke sudo or root privileges. Verify this elevated access is necessary and justified.
Confirm:
- Linux and a package matching `x86_64/amd64` or `aarch64/arm64`
- sufficient disk, CPU, memory, file permissions, and root/sudo access
- explicit region, TLS endpoint, and public/private network path
- network reachability to the package location and TLS endpoint
- the intended host group identity: Label by default, IP only when explicitly required
Marking a downloaded script in /tmp as executable is part of a potentially dangerous execution chain because /tmp is a shared, attacker-relevant location and the file is later run with elevated privileges. While chmod alone is not the exploit, the pattern encourages executing an untrusted network-retrieved artifact from a temporary path without strong provenance checks.
For a private network, the official guide may use the corresponding .ivolces.com domain. Validate the final URL with wget --spider or an equivalent HTTP check, then inspect what was downloaded:
chmod 755 /tmp/logcollector.sh
file /tmp/logcollector.sh
/tmp/logcollector.sh --help
The document instructs users to execute a downloaded script from /tmp with sudo while passing cloud credentials on the command line. If the downloaded installer is tampered with, this yields immediate root-level arbitrary code execution; additionally, credentials supplied as arguments may be exposed to local process inspection or shell history tooling depending on environment.
read -r -s -p "TLS SecretKey: " TLS_LOGCOLLECTOR_SK
printf '\n'
sudo /tmp/logcollector.sh install \
--region <region> \
--endpoint <explicit-tls-endpoint> \
--secret_id "${TLS_LOGCOLLECTOR_AK}" \
Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.
--input '{"HostGroupName":"","HostGroupType":"Label","HostIdentifier":"","ServiceLogging":true}'
The installed LogCollector label must exactly match `HostIdentifier`. For an explicitly requested IP group, re-read `host-group.create`, use its current `HostGroupType` and `HostIpList` contract, and configure installation with IP identity only. Do not combine label and IP identity.

The natural-language description includes both English and Chinese, but the file does not state that the skill is intended for bilingual users or provide an explicit language preference mechanism. Under the policy, language constraints or assumptions should be opt-in or clearly justified.
No suspicious patterns detected.
