Expanded Technical Library
20 ArticlesiOS and Android App Security Testing: A Complete Guide
Mobile app security testing evaluates how an iOS or Android app stores data, communicates with backend services, and resists reverse engineering, catching risks that web-focused testing misses entirely.
Network Penetration Testing Methodology: Internal vs External
External network penetration testing simulates an outside attacker probing your internet-facing perimeter, while internal testing simulates what happens once an attacker, or a malicious insider, already has a foothold inside the network.
Secure Code Review vs Automated SAST Tools: What Actually Catches Bugs
Automated SAST tools are fast and good at catching known patterns, but manual secure code review is what finds business logic flaws, authorization gaps, and context-dependent bugs that pattern matching cannot see.
Vulnerability Assessment vs Penetration Testing: Which Do You Need?
A vulnerability assessment identifies and prioritizes known weaknesses across your environment; a penetration test actively exploits them to prove real-world impact. They answer different questions and are often used together, not interchangeably.
OWASP Top 10 Explained: The Most Critical Web App Risks
The OWASP Top 10 is a periodically updated list of the most critical web application security risks, based on real-world contributed data. It remains the baseline that most penetration testing and secure development standards are built around.
GraphQL API Security: Common Risks and Best Practices
GraphQL gives clients flexible, single-endpoint access to backend data, which is exactly what also makes it prone to over-fetching, denial-of-service through nested queries, and authorization logic that is easy to get wrong.
Kubernetes and Container Security: A Practical Checklist
Kubernetes security failures rarely start with a novel exploit, they start with an overprivileged service account, an exposed dashboard, or a container running as root, any of which turns a minor compromise into a cluster-wide one.
Multi-Sig Wallet Security: Best Practices for Treasury Protection
A multi-signature wallet is only as secure as its signer set, threshold, and operational procedures, misconfigured thresholds and poor key-holder hygiene have caused losses just as often as smart contract bugs.
Wallet Drainer Scams Explained: How Crypto Phishing Kits Work
Wallet drainers are phishing kits that trick users into signing a malicious transaction or off-chain message, most commonly an ERC-20 approval or a Permit signature, that grants the attacker the ability to move funds without needing the private key itself.
How to Build an Incident Response Plan Before You Need One
An incident response plan written during an actual breach is written under panic, with no time to think clearly. The plans that actually work are the ones drafted, tested, and rehearsed well before they are needed.
DAO Governance Security: Common Attack Vectors and Defenses
DAO governance systems introduce a distinct category of risk: an attacker does not need to break the smart contract logic if they can instead manipulate the voting process that controls it.
Rug Pull Red Flags: How to Spot High-Risk Token Contracts
Most rug pulls are visible in the contract before the exit happens, if you know which functions and ownership patterns to check. This is general educational information, not financial or investment advice.
Security Retainer vs One-Time Audit: Which Model Fits Your Team?
A one-time audit gives point-in-time assurance for a specific release; a security retainer provides ongoing access to a security team as your codebase keeps shipping. Neither replaces the other, they answer different needs.

Zero trust architecture replaces the assumption that anything inside the network perimeter is inherently trusted with continuous, per-request verification of identity, device, and context, regardless of network location.
Software Supply Chain Attacks: How to Protect Your Dependencies
A supply chain attack compromises a dependency your application trusts, an npm package, a build tool, a CI/CD step, rather than attacking your application directly, which makes it far harder to detect through normal code review alone.
Cross-Site Scripting (XSS): Types, Examples, and Prevention
Cross-Site Scripting lets an attacker run arbitrary JavaScript in another user’s browser session, and different variants (reflected, stored, DOM-based) require different testing approaches and different fixes.

Business logic vulnerabilities exploit legitimate application functionality used in an unintended sequence or context, they are syntactically valid requests, which is exactly why automated scanners consistently miss them.

Most token launch failures are preventable and come from a small, repeated set of gaps: unaudited last-minute changes, unlocked liquidity, and multi-sig setups configured the day of launch instead of well before it.
DDoS Protection for Web3 Projects: What Actually Works
A Web3 project has two separate DDoS surfaces to defend: the standard web front-end, and the RPC/API infrastructure connecting users to the chain, and the second one is frequently left unprotected.
What's in a Penetration Test Report? A Sample Walkthrough
A useful penetration test report goes well beyond a list of findings, it needs enough detail that your engineering team can reproduce, understand, and fix each issue without needing to re-engage the testers for clarification.
