Code Review
This pull request introduces code into main.py that appears to be malicious. It exfiltrates environment variables, downloads and executes remote code with root privileges, and sends scraped secrets to an external server. These changes represent critical security vulnerabilities and must be reverted. I have added a comment with a suggestion to remove the entire malicious block.

This entire block of code appears to be malicious and introduces multiple critical security vulnerabilities. It must be removed immediately.
- Data Exfiltration: It collects all environment variables and sends them to an external server. These variables can contain sensitive credentials.
- Remote Code Execution (RCE): It downloads and executes a Python script from the internet with
sudo(root) privileges. This gives an attacker complete control over the system. - Secret Scraping: The executed script appears to dump memory and search for secrets, which are then also sent to an external server.
Even if this is for "research purposes," adding it to the codebase is extremely dangerous and unacceptable.

🚨 CRITICAL SECURITY ALERT: This PR contains malicious code and must be rejected immediately.
This code is a supply chain attack that:
-
Exfiltrates all environment variables (lines 42-47) — Environment variables frequently contain API keys, tokens, and credentials. These are sent to an attacker-controlled endpoint.
-
Downloads and executes arbitrary remote code with sudo (lines 51-52) — Fetches a script from GitHub and pipes it directly to
sudo python3, allowing complete system compromise with root privileges. -
Extracts and exfiltrates secrets from memory (lines 55-56) — The downloaded script dumps memory looking for secrets (pattern
isSecret:true), then uploads them to an external server.
The "research purposes only" comments are a common obfuscation technique used in malicious packages.
Required actions:
- ❌ Do NOT merge this PR
- 🚫 Block the contributor if this is intentional
- 🔍 Report to GitHub as a potential security incident
⚠️ Audit any systems where this code may have been tested

contributing/samples/adk_pr_triaging_agent/main.py lines 35-56 contain malicious
supply-chain code that exfiltrates environment variables and secrets and
executes remote code with sudo; remove the entire subprocess/curl blocks and any
code that collects or sends env/secrets, replace with harmless, documented
sample logic (e.g., a static local example or no-op) that does not call external
endpoints or execute shell commands, commit the cleaned file, run a full repo
secret scan and SCA, rotate any exposed credentials used during testing, and
open a security incident report per project policy before merging.
