The data is stored in an ERP system. Teachers access it. Administrators download spreadsheets. IT teams back it up to the cloud. A third-party vendor manages the learning app. A...
The Web3 industry continues its rapid evolution, bringing with it new forms of value exchange, decentralized business models, and high-velocity innovation.

In this environment, robust cybersecurity is not just...
In Part 1 of this series, we explored how authentication flaws and logic errors can compromise Web3 platforms – from brute-force attacks bypassing two-factor authentication to IDOR vulnerabilities that lock users out of their own funds. Those vulnerabilities were dangerous, but they required some level of exploitation skill and understanding of API manipulation. What we’re...
After a year of pen-testing Web3 applications at Securze, we’ve seen patterns that most security discussions miss.

Technical Walkthrough: Cause of the Breach The root cause of...
OAuth (Open Authorization) is a widely adopted authorization framework that allows applications to grant limited access to their resources without exposing user credentials. OAuth allows users to authenticate third-party applications without sharing passwords, instead using tokens to authorize access to protected resources. While OAuth is a powerful and flexible authorization protocol, improper implementation can lead...
