Summary
Recommends the 14k Stars open-source project blind_watermark, which embeds invisible watermarks in the DWT-DCT-SVD transform domain via frequency-domain steganography. The watermark is invisible to the naked eye and resistant to cropping, compression, re-photography, etc. Pure Python implementation, suitable for preventing leaks and piracy.

Why can internal screenshots from big companies always accurately trace the leaker?
The secret lies in “blind watermarking”. Today, I recommend a hardcore open-source project with 14k Stars: blind_watermark.
What makes it stronger than ordinary visible watermarks?
- Steganography in frequency domain: Hides the watermark in the DWT-DCT-SVD transform domain of the image, completely invisible to the naked eye.
- Devastating robustness: Even if someone crops, adds noise, heavily compresses, or re-photographs the image, the watermark can still be extracted.
- Out-of-the-box: Pure Python implementation, extremely developer-friendly.
Essential for preventing leakage of core assets and preventing image theft. Highly recommended to bookmark for later!

@vintcessun: A pure Go LLM privacy gateway that redacts PII/secrets in milliseconds—already in production. Two-layer detection: structured PII via regex (email, phone, ID, bank card), secrets/credentials via gitleaks rules plus Shannan entropy as fallback. Key design: no NER (avoids latency), only irreversible redaction; Go's native regexp is RE2, linear time with no backtracking risk.

Introduces an 8-stage vulnerability discovery agent based on Claude subscription, reproducing the core ideas of the Cloudflare Project Glasswing paper. It uses multiple narrow agents, intentional disagreement verification, and reachability gating to break down exploit analysis into precise steps, without the need for API keys.
@xiangxiang103: Wow, Anthropic really dropped the ball this time. Someone dug up hidden code in the Claude Code binary — specifically designed to detect whether you're a Chinese user or routing through China. Not ordinary telemetry, but deliberately obfuscated, not mentioned in release notes, and completely unknown to users. The process goes like this: - Detects you...
Hidden code was discovered in the Claude Code binary that specifically detects Chinese users or proxy routes, and secretly modifies system prompts to add watermarks, sparking widespread concerns about trust in developer tools.
@vintcessun: What troubles security teams most is too many false positives in the vulnerability discovery process and lack of closed-loop fix verification. Anthropic's reference implementation directly breaks the entire process into an auditable seven-stage pipeline. The core design is not about stacking features, but building a verification chain—each finding must go through independent sandbox reproduction, deduplication, scoring, and finally the patch must also pass regression testing...
Anthropic has released an open-source reference implementation for vulnerability discovery and remediation, building a verification chain with a seven-stage pipeline based on Claude, aimed at reducing false positives and ensuring closed-loop fix verification.
@ShenHuang: The number of stars an open-source project gets has nothing to do with code quality, release timing, or even features. WhaleBro's DeepSeek-TUI May 1 tweet got 375K views and 900 stars, while my similar open-source product OpenSeek got 51K views and 70 stars on its post yesterday...
This tweet analyzes the secret to getting stars for open-source projects, pointing out that the key lies in building identity recognition early in big accounts' comment sections, not just code quality. The author uses their OpenSeek and WhaleBro's DeepSeek-TUI as examples to illustrate the importance of reach and subsequent commercialization.
