Understanding Elliptic Curve Cryptography (ECC) Elliptic Curve Cryptography, commonly known as ECC, is a method for encrypting data to secure digital communications. It’s a form of “asymmetric cryptography,” which means it uses two different keys: a public key that anyone can see and a private key that must be kept secret. What Makes ECC Special?
Was it possible to prevent an $18M loss on BNB Chain? PART 1 – Root Cause and Arbitrum Attack On October 16, 2024, Radiant Capital suffered a security breach resulting in a more than $50 million USD loss ($48M in the attack itself and $5-6M via infinite approvals). The attackers infiltrated the devices of at
Hacken’s partnership with Europe’s first public-sector blockchain infrastructure, EBSI, is evolving. After successfully conducting a comprehensive smart contract audit last year, Hacken has now performed a proactive penetration test on EBSI’s APIs and web applications. Our latest security assessment employed both black box and gray box testing methodologies, ensuring the platform’s security and integrity across
The AnniversaryChallenge CTF was created with a dual purpose: to celebrate Hacken’s 7th anniversary and test the Solidity and EVM skills of potential newcomers. With this in mind, a multi-step exploit was implemented to solve the challenge. Thus, candidates were expected to: The CTF’s objective was to collect the TrophyNFT ERC721 token with Id 1
Uncover a critical risk in ECDSA: improper nonce management can lead to private key recovery attacks. Explore how this impacts blockchain systems and how to securely implement the Elliptic Curve Digital Signature Algorithm
Explore our in-depth case study on PhronAI, an AI-powered Layer-0 blockchain leading the way in decentralized AI integration.
Learn how Hacken’s audit helped ensure the security and efficiency of their protocol and tokenomics model.
A case study of ethical hacking detailing how Hacken’s L1 Researcher and Auditor, Bartosz Barwikowski, uncovered a deeply hidden bug in Weft Finance’s smart contract, exploited it to extract $1.1 million in assets (on a mainnet ledger copy) and ultimately helped secure the platform, leading him to confidently stake his own assets there.
**Role of a Merkle Tree**
A Merkle Tree is a data structure used in blockchain to ensure data integrity and efficient verification. Read how Hacken auditors joined the effort to secure OpenZeppelin’s MerkleProof.sol library.
In this guide, Hacken auditors will share best practices for secure MetaMask Snaps development to safeguard users’ assets and privacy.
