In an increasingly digital world, information is power. Open-Source Intelligence (OSINT) refers to the practice of collecting, analyzing, and interpreting data from publicly available sources to gain insights.

Whether you’re verifying a potential date’s background, checking for personal data leaks, or researching...

It’s funny how history can teach us about the present. People were figuring out how to keep themselves, their secrets, and their belongings safe from prying eyes and sticky fingers long before we had firewalls, VPNs, or two-factor authentication. We’re discussing operational security, or OpSec for short, which is all about preventing the bad guys from piecing together your plans from the scraps you leave behind, privacy, or keeping personal matters private, and security, or protecting against...

Without them, each chain would remain a siloed economy, stifling the growth of DeFi and NFTs. Bridges enable users to, say, deposit ETH on Ethereum and withdraw an equivalent wrapped version (wETH) on Polygon for cheaper transactions. In the sprawling universe of blockchain technology, cross-chain bridges serve as vital conduits, allowing digital assets to flow seamlessly between isolated networks like Ethereum, Solana, and Binance Smart Chain. These bridges unlock liquidity, enable DeFi inno...

In the fast-evolving world of blockchain and decentralized finance, smart contracts are the backbone of trustless systems. They automate transactions, manage assets, and enforce rules on immutable ledgers like Ethereum or Solana. However, this immutability cuts both ways: once deployed, a flawed smart contract can lead to catastrophic losses. According to reports, over $14.8 billion has been lost to crypto exploits between 2020 and 2024, with a 21% annual increase in incidents. Building a rob...

Looking at this year’s never-ending hacks, one wonders why they happen so frequently. Have audit firms actually gotten worse at what they do? This, in my opinion, is not the case; yet, the topic is rather tricky because you can, in certain ways, reduce the risks to yourself and your project! The need for robust security tooling is becoming increasingly critical as the attacks are becoming more complicated and coming from different directions apart from code. One innovative solution that is on...
