🇮🇳 Building OmniCore OS: From an Idea to a Working Development Build A few days ago, I shared the vision behind OmniCore OS. Today, I want to share the next step in that journey. The idea is no longer just a concept. OmniCore OS is now booting as a working development build. Getting an operati
HMAC Proves Origin, Not Freshness: Replay Attacks Against Signed APIs The signature verified. The secret was correct. The payment processed for the fourth time, from a request captured three hours earlier. HMAC proves that a request came from someone who knows the secret. It does not prove when.
Every JWT carries a header parameter whose only job is to tell the server which key to use. The RFC does not define the format of that parameter. Most libraries do not validate what arrives in it. The kid parameter is processed before signature verification. When a server passes that value directly
A logged-in user visits a page you do not control. Your WebSocket server opens a new authenticated connection to that page's JavaScript. The attacker reads every message your server sends and can write any message your server accepts. No XSS. No phishing. Just a missing header check. Cross-Site Web
Passwordless auth was supposed to eliminate credential phishing. Instead, it moved the credential from a password field into a URL, a log file, and an email inbox. Magic links encode auth tokens in URLs that end up in server logs and Referer headers. TOTP verification endpoints are rarely protected
Race Conditions in APIs: TOCTOU in Payments, Coupons, and Rate Limiting Every standard scanner sends request A, waits for the response, and only then sends request B. Every race condition in production lives in the window between a server-side check and the update that follows it. These two facts
The Problem & Industry Shift The OpenBSD project is renowned for its security focus, but its hardware support philosophy is equally distinctive: it actively supports a vast array of obscure and obsolete devices, some of which feel like relics from a medieval technological era. While mainstream
Four questions decide almost everything: where your data goes, whether the vendor is still alive, what happens when you uninstall, and what the bill looks like when the team grows. Everything else is detail. Short answer. Look for the Runs on Atlassian badge, which is a verified technical fact rath
Following the path from untrusted content to agent permissions, credentials, and external actions. Hermes Agent is useful because it can do more than answer questions. It can run tools, connect to MCP servers, schedule work, and continue tasks across sessions. That connectivity changes the securit
Pessoal, eu ia colar o Juice Shop na tabela do post das três portas. Tinha 13 findings com requisito ASVS e arquivo:linha. SQL concatenado, eval no username, CORS *, cesto de outro usuário. O modelo tinha trabalhado. A tabela ia ficar “mais completa”. Aí li o package.json: probably the most modern
A local-first app still needs a good answer to one basic question: how does a person know that the phone in their hand is connecting to the right computer? For iWinBridge, the answer is a QR code. It sounds like a small UI detail, but it changes both the setup experience and the trust model for iPh
Hi DEV! I was fed up picking up my phone to type a six digit code into the machine I was already sitting at. The desktop authenticators I tried either wanted an account, synced my secrets to their cloud, or both, which rather defeats the point of the thing being under my control. AuthGeek is a TOT
Build an editor on Flutter Web. The user opens budget.csv, edits it, hits save. They get budget.csv in their Downloads folder. They edit again, save again: budget (1).csv. Again: budget (2).csv. Their real file — the one on their Desktop that they opened — has never been touched. By the end of an
As I continue learning and working in the tech field, I have been learning not only how to build websites and applications, but also how to handle account credentials securely. Recently, I was introduced to Bitwarden, a password manager that can also be used to securely share sensitive information.
That Time Someone Exploited a Git Hook to Root Your Homelab You know how it is—you spin up a self-hosted Git instance, maybe Forgejo or Gitea, and you're feeling good about having your own GitHub alternative. Then you forget about it for a while. That's usually when something bad happens. Someone

Somebody types "can we loop in finance on this?" in a product channel. Nobody tags the finance channel. The thread moves on. Three weeks later there is a contract nobody in finance has seen. That is not a tooling problem in any obvious sense. Slack worked exactly as designed. Search would have foun

The missing piece for an end-to-end data pipeline, entirely on AWS, from space. Camping in the North Cascades growing up, stargazing was a treasured pastime for me. My dad and I would often read between the lines of stars and planets to look for satellites... nowadays, they're so common, it's hard
