    Did you know that VSCode extensions run with full access to your system—including file system, network, and credentials? Worse, dozens of malicious extensions have already made it into the marketplace, silently compromising devices. I am a security researcher and student developer who ran into this problem myself. To help tackle this, I built a 100% free tool (no login required) that scans VSCode (and Cursor/Windsurf) extensions for: - Hidden malware and obfuscated code - Dangerous permissions and API misuse - Vulnerable dependencies and suspicious network connections Users have already…

    I noticed the growing security concerns around MCP (https://news.ycombinator.com/item?id=43600192) and built an open source tool that can detect several patterns of tool poisoning attacks, exfiltration channels and cross-origin manipulations. MCP-Shield scans your installed servers (Cursor, Claude Desktop, etc.) and shows what each tool is trying to do at the instruction level, beyond just the API surface. It catches hidden instructions that try to read sensitive files, shadow other tools' behavior, or exfiltrate data. Example of what it detects: - Hidden instructions…

    We're launching SecureBuild: https://securebuild.com — a new way for open source projects and maintainers to earn revenue by partnering with and endorsing our Zero-CVE container images of their project.

    hey guys, wanted to show one of my side projects i just made public. the idea is basically another osint tool for pentesters and bug bounty hunters. it watches certificate transparency logs and checks newly-seen domains for exposed stuff like .env files, open .git dirs, config files, db dumps and so on, and puts whatever it finds into a searchable db. you just search a domain (or part of one) and see what's exposed. it's read-only and free. one thing i've been thinking about adding is a way to register for certain keywords and get notified when something new shows up for that search. would…
