Hacker Sidekick is a desktop application that gives penetration testers, red teamers, blue teamers, and security engineers an AI environment purpose-built for cybersecurity work. Built on a VS Code-based interface, it combines an AI model fine-tuned for security contexts with agentic execution โ€” meaning it chains tools together and runs multi-step workflows rather than just providing advice.

Sovereign AI Unlike general-purpose AI assistants, Hacker Sidekick's models are built for cybersecurity work. The AI generates exploit code, analyzes malware samples, writes attack narratives, and works with offensive security terminology natively โ€” without the content restrictions that block legitimate security research.

Agentic Execution Hacker Sidekick executes workflows rather than just chatting. It chains tools like Nmap, vulnerability scanners, and custom scripts into automated pipelines, maintains context across an entire engagement, accesses the terminal on your machine, and produces structured output including reports and documentation.

Local-First Architecture Runs on Windows, macOS, and Linux. Integrates with tools already on your system โ€” Kali Linux, Burp Suite, WSL, Metasploit, and custom scripts. Data stays on your machine by default.

Use Cases Offensive: penetration testing, web application assessment, code analysis, threat emulation (MITRE ATT&CK), bug bounty reconnaissance. Defensive: alert triage, detection engineering, threat hunting, incident response, compliance reporting.

Deployment Individual download (free tier available), team deployment via SSO, and on-premises enterprise deployment with centralized management.

The other option is to host your own PiHole. NextDNSโ€™s service is modelled on PiHole, and openly admit this in their FAQ. I personally host my own PiHole on a RaspberryPi 3b+ and have my traffic in my apartment routed through this. I trust NextDNS to protect me while I am on my mobile data, or in a coffee shop, but at home, I enjoy knowing that I have 100% control over my...

  • Cloudflare flags archive.today as "C&C/Botnet"; no longer resolves via 1.1.1.2

    While on the subject, does anybody know any good ad-blocking solutions for mobile phones? So far I have experimented with NetShield from ProtonVPN and https://nextdns.io/ with varying results. There are also features baked into certain browsers like the cookie blocker with DuckDuckGo which works extremely well, and UnTrap for Safari on iOS which allows for heavy Youtube web customisation. Also, shout out to... - Source: Hacker News / 6 months ago
  • Europe is scaling back its landmark privacy and AI laws
    I work right at the junction of marketing tech -- eCommerce, marketing sites, account management systems. Theoretically I should be living in compliance hell, but here's the dirty secret: To "follow" every rule, all you really need is another layer of UX friction. Another modal. Another "consent wizard."

  • Show HN: NextDNS Adds "Bypass Age Verification"
    We just shipped a new feature in NextDNS: Bypass Age Verification. More and more sites (especially adult ones) are now forcing users to upload IDs or selfies to continue. We think thatโ€™s a terrible idea: handing over government documents to random sites is a huge privacy risk. This new setting workarounds those verification flows via DNS tricks. Itโ€™s available today to all users, including free accounts. Weโ€™re... - Source: Hacker News / 11 months ago
  • Tell HN: uBlock Origin on Chrome is finally gone
    NextDNS [0] has proven very useful for me on iOS. Firefox is 99% ad-free. Only for YouTube do I switch to Brave Browser. My home router (Draytek) is also configured to force any connected devices to use NextDNS too. Definitely worth the โ‚ฌ20 annual subscription.
